家里的二哈爱吃花
白粉病 白粉病可以说是养月季的花友最害怕遇到的病了，既影响月季的美观，又妨碍月季的正常生长。 [图片]白粉病表现 初期叶片有少许细微的白色颗粒，然后白色颗粒逐渐聚集成一层白色粉末状物质，严重时，整片叶子、枝干、花苞都被白色粉末覆盖。 预防措施 白粉病主要发生在春秋季节，干燥、通风差都会引起白粉病。所以，月季栽种时不要太密，在室外接受太阳直射的太阳要时常向植株周围喷水，保持湿度。 救治方法 将粉锈克与水按照1:1500的比例配制，喷洒全株，可在溶液中加少量百菌清进行辅助预防。 黑斑病 月季对黑斑病几乎没有任何抵抗力，几乎所有月季都会得黑斑病，简直是“头号祸害”！ [图片]黑斑病表现 起初为褐色小斑点，逐渐发展成黑褐色大斑，严重时导致叶片发黄，脱落甚至造成秃枝！ 预防措施 黑斑病主要是高温多雨天气造成的，所以要在雨季做好预防。下雨后要立刻喷洒杀菌药，及时摘除病变叶片，以防扩散。 救治方法 1、喷药 10毫升阿米妙收药剂兑15升水，喷洒时要均匀，叶片的反面、茎杆发病部位也要喷洒。 2、浇水 月季发病后，浇水时要格外注意，最好沿着盆边浇灌土壤，尽量避免叶片上有水。保持月季通风良好，可适当修剪，保持透光性。 根瘤病 地栽的月季特别容易得根瘤病，嫁接月季比扦插月季得此病的几率高许多，并且根瘤病极易传染。 [图片]预防措施： 在栽植月季之前先用K84兑水3倍，进行蘸根，这样有助于抑制根瘤病的发生。 救治方法： 若根瘤程度不严重，可以用消毒后的小刀把肿瘤切掉，切至木质部位，然后用高锰酸钾涂抹创口。若过于严重，最好将植株舍弃，对土壤进行消毒。 红蜘蛛 红蜘蛛应该是种月季的花友最头疼的一种害虫，不仅是月季，红蜘蛛也是大部分花卉都容易招的一种害虫。 [图片]红蜘蛛危害 红蜘蛛泛滥的环境主要是高温、干燥且通风不畅。红蜘蛛会造成叶片出现黄色斑块，叶片枯黄直至脱落。 红蜘蛛解决方法 用阿维菌素药剂兑水喷洒3天1次，连续3次，注意叶子反面也要喷到，严重时，可2天1次。 蚜虫 蚜虫应该也是花友比较熟悉的了，每到春天就遭受蚜虫的折磨，苦不堪言！ [图片]蚜虫危害 蚜虫多发于干旱少雨的早春季节，会导致月季叶片、花苞发育不正常，吸收月季的汁液，造成月季长势变慢，甚至引发其他病害。 蚜虫解决方法 蚜虫不多时可以用手直接捏死，如果大量爆发，可以用蚍虫林喷洒。 你家的月季得过这些病吗？ 你有什么独家解决方法呢？ 欢迎留言分享~

Description: This herbaceous plant is a biennial or short-lived perennial. During the first year, several basal leaves are produced, but thereafter this plant bolts to produce flowering stalks about 4-8' tall. The central stem is light green, stout, terete with vertical ridges, more or less covered with spreading white hairs, and usually unbranched. The interior of the this stem is hollow. Widely spreading alternate leaves are located primarily along the lower half of the central stem, becoming smaller in size above. The lower to middle alternate leaves are ternately compound (divided into 3 leaflets); they are 8-20" long and similarly across in outline. The leaflets are 4-12" long and ovate or orbicular in outline; they are shallowly to moderately cleft into 3-5 lobes and coarsely toothed. The lobes of leaflets are ovate in shape; they have broad acute tips. The upper leaflet surface is grayish green, medium green, or yellowish green and rough-textured, while the lower leaflet surface is slightly more pale and hairy along the primary and secondary veins. The petioles of lower to middle leaves are 3-10" long, light green, hairy, and relatively stout (especially at the base). The petiole bases are partially enclosed by a pair of hairy membranous sheaths. These sheaths are light green, purplish green, or nearly white from abundant hairs. Upper leaves are usually simple, ternately lobed, and coarsely toothed; they are up to 4" long and similarly across. The lobes of upper leaves are lanceolate with acute tips. The upper leaves have petioles up to 2" long. The central stem terminates in a compound umbel up to 8" across. Additional compound umbels are produced from the axils of upper leaves on long peduncles (flowering stalks); these axillary umbels are up to 6" across. The compound umbels are more or less flat-headed. Each compound umbel has 8-30 rays that terminate in umbellets; each umbellet has 8-30 flowers. The rays of the compound umbels are 2-5" long, light green, and pubescent; the pedicels of the flowers are ¼–¾" long, light green, and pubescent. Individual flowers span a little less than ¼" across. Each flower has a light green calyx that is shaped like a saucer, 5 white petals, 5 stamens, and a whitish ovary with a pair of tiny styles. The petals are strongly incurved at their tips. The blooming period occurs from late spring to mid-summer, lasting about 1 month. Afterwards, the flowers are replaced by fruits (schizocarps); each fruit consists of a pair of seeds. Individual immature fruits are about 8 mm. (1/3") in length, 6 mm. (1/4") across, and somewhat flattened; they are elliptic-obovoid in shape, light green with white margins, and there are 4 vertical dark green veins toward the center of each flattened side. Mature fruits become tan to dark brown, and their lateral margins become flattened into wings; they are distributed to a limited extent by the wind before dividing into seeds. The root system consists of a taproot or a cluster of thick roots. This plant reproduces by reseeding itself. [图片]Cultivation: The preference is full sun to light shade, moist conditions, and fertile soil containing loam, silty loam, or sandy loam. The size of individual plants can vary considerably. Some protection from strong wind is desirable. Because Cow Parsnip can irritate human skin, it is best to wear gloves while handling its foliage. Range & Habitat: The native Cow Parsnip is occasional in central and northern Illinois, while in the southern section of the state it is uncommon (see Distribution Map). Habitats include bottomland woodlands, terraces of floodplain woodlands, borders of woodlands, woodland openings, meadows in wooded areas, riverside prairies, thickets, streambanks, and partially shaded roadsides. Cow Parsnip can be found in both high quality natural areas and disturbed habitats. [图片]Faunal Associations: The flowers of Cow Parsnip attract a large diversity of insects because of its easily accessed nectar and pollen. These floral visitors include honeybees, cuckoo bees (Nomada spp., Sphecodes spp.), plasterer bees (Colletes spp.), masked bees (Hylaeus spp.), Andrenid bees, Halictid bees, Sphecid wasps, Vespid wasps, spider wasps (Anoplius spp., etc.), Tiphiid wasps, Ichneumonid wasps, dark-winged fungus gnats (Sciara spp.), soldier flies (Stratiomys spp., etc.), Syrphid flies, dance flies (Empis spp., Rhamphomyia spp.), Tachinid flies, flesh flies (Ravinia spp., Sarcophaga spp., etc.), blow flies (Lucilia spp., etc.), Muscid flies, frit flies (Liohippelates spp., Olcella spp.), long-horned beetles (Strangalepta spp., Trigonarthris spp., etc.), tumbling flower beetles (Mordellidae), flower chafers (Trichiotinus spp., etc.), plant bugs (Miridae), and occasional butterflies (Robertson, 1929; Gosling, 1986). Some insects feed destructively on the foliage, fruit, and sap of cow parsnip. These insect feeders include the larvae of leaf-mining flies (Phytomyza spp., etc.), larvae of Euleia heraclei (Hogweed Picture-wing Fly), larvae of Depressaria pastinacella (Parsnip Webworm Moth), Orthops scutellatus (Carrot Plant Bug), Taeniothrips vulgatissima (Cow Parsnip Thrips), and such aphids as Aphis decepta, Cavariella aegopodii (Willow-Carrot Aphid), Cavariella pastinacae (Willow-Umbellifer Aphid), and Cavariella theobaldi (Willow-Parsnip Aphid); see Needham et al. (1928), Knight (1941), Stannard (1968), and Blackman & Eastop (2013). Some mammals feed on the flowers and foliage of Cow Parsnip, particularly in the western United States. There are records of bears, elk, deer, cattle, horses, and sheep feeding on this plant (Esser, 1995). However, when this plant is exposed to the ultraviolet radiation of sunlight, the foliage can become phytotoxic, causing blisters to form on the skin and possible irritation of the digestive tract (Georgia, 1913). This toxic side effect is the result of light-sensitive furanocoumarins. Cow Parsnip shares this characteristic with another species in the Carrot family, Pastinaca sativa (Parsnip). [图片]Photographic Location: Border of a woodland along a road at Illinois Beach State Park in NE Illinois. Comments: Because of the large size of its compound umbels, Cow Parsnip is one of the best sources of nectar and pollen for a wide variety of insects, especially small bees, wasps, flies, and beetles. This plant can be distinguished from other species in the Carrot family primarily by its large size (up to 8' tall or more), large ternately divided leaves, and hairy foliage. Other scientific names of Cow Parsnip include Heracleum lanatum and Heracleum sphondylium montanum. The latter scientific name, Heracleum sphondylium, refers to European Cow Parsnip. This plant species has compound leaves with 3-7 pinnately arranged leaflets, while the Cow Parsnip of North America, Heracleum maximum, has only 3 leaflets per compound leaf. Both plant species are about the same size. A third species that is native to Eurasia, but has naturalized in parts of North America, is Heracleum mantegazzianum, or Giant Hogweed. This is a much larger plant that becomes 6-18' tall at maturity. The compound leaves of Giant Hogweed are also larger in size than the preceding plant species in its genus; they are pinnate-pinnatifid or pinnate-bipinnatifid with narrowly acute lobes.

Description: This herbaceous perennial plant is about 3-6" tall. It consists of a tuft of basal leaves that develops during the late spring and persists through the winter. These leaves are up to 3" long and across; they have slender petioles up to 6" long. Each leaf is palmately divided into 3 lobes; the lobes are oval-ovate and approximately the same size. The smooth upper surface of each leaf can be green, brownish green, reddish brown, or contain patches of the preceding colors; usually, the upper surface is more green during the summer, but become reddish brown during the winter. The leaf margins are smooth; for var. acuta, the tips of the lobes are rather pointed in mature leaves. A mature plant will produce a tuft of flowers on long stalks during early to mid-spring, by which time the basal leaves that persisted during the winter may have withered away. Each flower occurs on a naked hairy stalk about 3-4" long; this stalk is often reddish green or reddish brown. The flower may be erect or it may nod on its stalk. Each flower is up to 1" across, consisting of 5-11 petal-like sepals, a green cluster of carpels in its center, and numerous white stamens surrounding the carpels. The sepals are white, pastel pink, or pastel blue; each sepal is oblong-oval in shape. At the base of each flower, there are 3 leafy bracts that are lanceolate, ovate, or oval in shape. These bracts are reddish green or reddish brown, hairy across the outer surface, and shorter than the sepals. The blooming period occurs during early to mid-spring and lasts about 2-3 weeks for a colony of plants; however, individual flowers are short-lived. The carpels turn brown and become beaked achenes that are often pubescent. The root system consists of a tuft of fibrous roots. This plant spreads by reseeding itself. [图片]Cultivation: The preference is dappled sunlight during the spring and light shade during the summer. The basal leaves should be left undisturbed during the winter. The soil should be well-drained, loamy, and can contain some rocky material, including pieces of limestone; a thin-layer of decaying leaves is also beneficial. Range & Habitat: The native Sharp-Lobed Hepatica is occasional in wooded areas of central and northern Illinois; it is uncommon or absent in southern Illinois (see Distribution Map). Habitats include upland deciduous woodlands, rocky bluffs, the slopes of bluffs, and limestone cliffs (where some shade occurs). Sharp-Lobed Hepatica occurs in high quality wooded areas where the original flora is largely intact. Sometimes it is cultivated as a rock garden plant. While Sharp-Lobed Hepatica is native to North America, the typical variety of Hepatica, Hepatica nobilis nobilis, occurs in Eurasia. [图片]Faunal Associations: Small bees collect pollen from the flowers, while Syrphid flies and other flies feed on the pollen. Bee visitors include honeybees, Small Carpenter bees, Andrenid bees, and Halictid bees. Nectar is not provided by the flowers. Chipmunks reportedly eat the achenes. The brownish green basal leaves are poisonous and somewhat camoflaged; it seems unlikely that they are eaten by mammalian herbivores to any significant extent. Photographic Location: The photographs of the blue and white flowers were taken at Kickapoo State Park, Vermilion County, Illinois, while the photographs of the pink flowers and basal leaf were taken on a sloping bank of the Sangamon river in Allerton Park, Piatt County, Illinois. [图片]Comments: The flowers of Sharp-Lobed Hepatica bloom earlier than most spring-blooming wildflowers of woodlands. They are delicately attractive and have a tendency to blow about on their slender stems in the wind. Another native variety of this plant species is Hepatica nobilis obtusa (Round-Lobed Hepatica), which has a very similar appearance, except that the lobes of its basal leaves are well-rounded rather than pointed. This latter variety is apparently restricted to NE Illinois. Sometimes these two varieties intergrade where their ranges overlap. Some authorities refer to Sharp-Lobed Hepatica as Hepatica acutiloba, while Round-Lobed Hepatica is referred to as Hepatica americana. Another common name for Hepatica is Liverleaf, which refers to the appearance and shape of the leaves.

Description: This wildflower is a summer annual about 4-12" tall that is branched or unbranched. The stems are light green, terete, and pubescent. The opposite leaves are about 1" long and ¼" across; they are elliptic, oblong-lanceolate, or oblong-oblanceolate in shape. The margins of the leaves are smooth or they have a few blunt teeth toward their tips. The petioles of the leaves are short and slender. The foliage of American Pennyroyal has a strong medicinal-mint scent. Small axillary clusters of 1-4 flowers are produced from the base of each middle to upper leaf. Each flower is about ¼" long and half as much across, consisting of a 2-lipped tubular corolla, a tubular calyx with 5 teeth, 2 stamens, and a 4-celled ovary with a single style. The corolla is white or blue-violet with a contrasting color near its throat. Along the outer rim of the corolla, there is an upper lobe, 2 lateral lobes, and a lower lobe; they are short and rounded (although not always well-defined). The hairy ridged calyx has 3 upper triangular teeth and 2 lower teeth that are slender-lanceolate. At the base of each flower, there is a pair of a leafy bracts; these bracts are at least as long as the flower. The blooming period occurs from mid-summer to early fall and lasts 1-3 months; individual flowers are short-lived. At maturity, each fertile flower is replaced by 4 nutlets. This wildflower reproduces by reseeding itself. It occasionally forms colonies at favorable sites. Cultivation: The preference is full sun to light shade, mesic to dry conditions, and soil that is rocky or loamy. Plants that are grown in sunny locations require more moisture than those growing in shade. Barren or disturbed locations that are largely devoid of ground vegetation are preferred, as this reduces competition from taller plants. Range & Habitat: The native American Pennyroyal is occasional to locally common throughout Illinois, except the NW section of the state, where it is less common (see Distribution Map). Habitats include dry upland woodlands, rocky woodlands, areas along woodland trails, rocky glades, areas along railroads, roadsides, pastures, and fallow fields. This species prefers areas (whether sunny or shaded) that have been subjected to some disturbance. Faunal Associations: Small bees pollinate the flowers, where they seek nectar and pollen. These visitors include little carpenter bees (Ceratina spp.), Halictid bees (Augochlorella spp., Halictus spp., & Lasioglossum spp.), and the dagger bee Calliopsis andreniformis. Syrphid flies may visit the flowers occasionally, but they feed on the pollen and are less effective at pollination. The strong scent of the foliage protects this plant from mammalian herbivores. [图片]Photographic Location: An upland area of Busey Woods in Urbana, Illinois. Comments: The most remarkable thing about this little plant is the strong scent of the foliage. Otherwise, it is rather easy to overlook. The only other species in this genus that occurs in Illinois, Hedeoma hispida (Rough Pennyroyal), has linear leaves and a milder scent; it also prefers sunnier habitats. American Pennyroyal superficially resembles Gratiola neglecta (Clammy Hedge Hyssop), but this latter species lacks any fragrance and its prefers soggy habitats (e.g., damp depressions in woodlands). Native pennyroyal species (Hedeoma spp.) have only 2 stamens per flower, while other similar species in the Mint family often have 4 stamens per flower. Because the flowers are so small, this requires a 10x hand lens to see clearly.

Description: This biennial plant forms a rosette of leaves during the first year. During the second year, it becomes a rather lanky plant about 2-4' tall that branches occasionally. The stems have abundant white hairs; the lower central stem is often ribbed. The basal and lower leaves are up to 6" long and 3½" across; they are cordate-ovate or ovate with petioles up to 2" long. The upper leaves are lanceolate to elliptic and sessile, otherwise they are similar to the lower leaves. All leaves have smooth (entire) and slightly ciliate margins. The upper leaf surface is dark green and sparsely covered with short stiff hairs, while the lower leaf surface is medium green and more hairy, especially along the major veins. Both the lower and upper leaves alternate along the stems. The upper stems terminate in flowering racemes about 4-12" long; sometimes shorter racemes or individual flowers develop from the axils of the upper leaves. The stalks (peduncles) of these racemes are pubescent or hairy, and small leafy bracts may develop underneath some of the flowers. The pedicels of the flowers are pubescent or hairy and up to ¼" (6 mm.) in length. Each flower is about 1/8" (3 mm.) across, consisting of 5 petals and a pubescent green calyx with 5 slender teeth. The petals are white and well-rounded; less often, they are light blue. The blooming period occurs during the summer, lasting about 2-3 months. Only a few flowers are in bloom at the same time and they are fairly inconspicuous. The flowers are replaced by prickly subgloboid fruits (about 4-6 mm. across) that hang downward from short slender pedicels (one fruit per flower). Hooked prickles densely cover the surfaces of these fruits. The fruits are initially whitish green, but later they later become brown. Each fruit contains 4 nutlets. The root system consists of a taproot. This plant spreads by reseeding itself; it occasionally forms colonies. [图片]Cultivation: The preference is partial sun to medium shade, mesic conditions, and a fertile loamy soil. However, this plant tolerates different kinds of soil and moisture conditions and it is quite adaptable. Range & Habitat: The native Stickseed is common in central and northern Illinois, and locally common to absent in the southern section of the state (see Distribution Map). Habitats include moist to slightly dry deciduous woodlands, woodland borders, powerline clearances in wooded areas, thickets, and shady fence rows. Stickseed prefers disturbed wooded areas and it is rather weedy. This plant sometimes occurs in wooded areas where there has been a recent fire, as well as degraded wooded areas that are subjected to occasional grazing by cattle. [图片]Faunal Associations: The nectar of the flowers attracts Halictid bees (Halictus spp., Lasioglossum spp.) and Syrphid flies, particularly Syritta pipiens. A flea beetle, Longitarsus melanurus, feeds on the leaves of Stickseed and other members of the Borage family. The bitter foliage is avoided by deer and other mammalian herbivores. When there is an overpopulation of deer in wooded areas, Stickseed often becomes more common. The bur-covered fruits can cling to the fur of mammals and clothing of humans; by this means, they are introduced into new areas. Photographic Location: Edge of a wooded area at Busey Woods in Urbana, Illinois. [图片]Comments: This is another woodland wildflower with small white flowers that blooms during the summer in shaded areas. The most distinctive characteristic of Stickseed (Hackelia virginiana) are the prickly fruits that hang downward from its slender racemes. Another species in the Borage family, European Stickseed (Lappula squarrosa), has similar racemes of prickly fruits. However, the prickles of its fruits are arranged in columns with spaces in-between. In contrast, the fruits of Stickseed are densely covered with prickles throughout. European Stickseed is shorter than Stickseed and its leaves are more slender. This introduced species prefers sunny areas, while the native Stickseed prefers wooded areas with some shade. An older scientific name for Stickseed is Lappula virginiana.

Description: This small perennial orchid produces a low rosette of evergreen basal leaves. Individual leaves are 1½-2½" long and ¾-1½" across; they are ovate or broadly elliptic and smooth along their margins. There are 5-7 primary veins per leaf; they are parallel. These veins are interconnected through a network of secondary veins. Both the primary and secondary veins are accented in white, while the remaining leaf surface is dark green. The basal leaves taper abruptly to petiole-like bases that are short and winged, where they are also accented in white along their central veins. After several years, a spike-like raceme of flowers develops from the basal rosette that is 4-14" tall and more or less erect. The central stalk of this inflorescence is light green, glandular-pubescent, and terete. Along the lower two-thirds of its length, there are widely separated leafy bracts. These bracts are small in size (about ½" in length), linear-lanceolate in shape, and ascending to erect. Along the upper one-third of the central stalk, the small flowers are densely distributed, facing in all directions. The sepals and petals of these flowers (3 of each per flower) are white or greenish white, while their inferior ovaries are green and glandular-pubescent. The upper sepal and 2 lateral petals of each flower are merged together to form a hood with a slightly upturned outer rim, while the 2 lateral sepals are free and the lower petal forms an open pouch with a minute down-turned beak. These petals and sepals are 3.5-5.5 mm. long; the outer surfaces of the hood and lateral sepals are minutely pubescent. The ovaries are 6-8 mm. long, ellipsoid in shape, and ascending. At the bases of the ovaries, there are ascending floral bracts. These bracts are green, glandular-pubescent, linear-lanceolate in shape, and ascending; they are about the same length as the ovaries. The blooming period occurs during mid- to late summer, lasting about 3-4 weeks. There is no noticeable floral fragrance. Afterwards, the flowers are replaced by seed capsules that become ovoid in shape and brown at maturity. At this time, these capsules split open into several sections to release their minute seeds to the wind. The root system consists of a shallow creeping rhizome with coarse fibrous roots. After flowering, this rhizome forms 1-3 clonal offsets. The clonal offsets become independent on their rhizomes, while the original rhizome dies. The evergreen basal leaves persist for at least 1½ years (at least 2 summers and 1 winter). [图片]Cultivation: The preference is medium shade to dappled sunlight, mesic to dry-mesic conditions, and an acidic loose soil that contains loam, loess (wind-blown silt from a prior ice age), or glacial till with decaying organic matter. The site should be protected from drying winds and it should be relatively humid. The root system of this orchid benefits from an endomycorrhizal association with certain kinds of fungi. This orchid has been successfully cultivated indoors in terrariums (Ugiansky, 2010). It should not be collected from the wild, which can easily destroy local populations. Range & Habitat: The native Downy Rattlesnake-Plantain is uncommon in Illinois, occurring mostly in northern and southern Illinois (see Distribution Map). Habitats include upland woodlands, north-facing wooded slopes, bluffs, large wooded ravines or sandstone canyons, sandstone glades, and woodlands damaged by logging. On rare occasions, this orchid has also been found in forested bogs. It is often associated with such canopy trees as oaks, pines, Eastern Hemlock (Tsuga canadensis), or sugar maple (Acer saccharum). This orchid usually occurs in high [图片]Faunal Associations: The small flowers are cross-pollinated by bees, including bumblebees (Bombus spp.) and green metallic bees (e.g., Augochlora spp., Augochlorella spp.); see ILPIN and Homoya (1993) for more information. Aside from this, little is known about floral-faunal relationships for this orchid. The evergreen leaves may be browsed by deer and the rhizomes may be eaten by chipmunks or mice, but additional study of such potential threats is required. Photographic Location: A rocky bluff dominated by Eastern Hemlock (Tsuga canadensis) at a nature preserve in east-central Indiana. Comments: While the flowers of Downy Rattlesnake-Plantain are rather small, the reticulated patterns of its basal leaves are very ornate and unique, making this orchid easy to identity. In spite of its common name, this orchid is not closely-related to plantains (Plantago spp.); its leaves have a shape that is similar to some of the common broad-leaved plantains. The common name is also inspired by the superficial resemblance of the leaves' reticulated patterns to the skin of a rattlesnake. The inflorescence of Downy Rattlesnake-Plantain resembles those of the Lady Tresses' Orchids (Spiranthes spp.), although they have dissimilar leaves. The flowers of the former orchid differ from those of the latter by the pouch-like structure of their lower lips, which is lacking in the flowers of Lady Tresses' Orchids. There are other orchid species in the Goodyera genus, but their ranges are located outside of Illinois, mostly to the north or northeast.

姬星美人是非常袖珍的多肉植物品种，"姬"正代表她"迷你"的意思，翡翠般的深绿色细小叶片很适合用于多肉拼盘的点缀，十分适合摆放窗台、阳台和客厅。姬星美人正常的颜色应该是蓝绿色，夏天阳光强的情况下，姬星美人会变的矮小，匍匐在地上，颜色呈现非常迷人的所谓的蓝粉色，非常的可爱。 [图片]姬星美人叶子变黄原因：正常现象 若姬星美人靠近地表的叶片开始发黄，逐渐萎蔫，是正常现象，因为植株在生长过程中，不会伴随着养分的消耗。多肉植物会消耗底部的叶片来获取养分，而且底部都是一些老叶，萎蔫之后不会影响植株的生长，反而会加快植株自身的代谢，促进更新。 姬星美人叶子变黄原因：浇水过多 乍一看到图片，许多肉友会说，哇塞，很漂亮啊，这是叶片发黄的前兆，主要原因就是浇水过多，每个枝条顶端的较大的叶片会变成透明状，颜色较浅。浇水过多，造成根部腐烂，枝叶水分吸收受阻，造成生理性缺水，从而造成叶子发黄。 在养护过程中尽可能的少浇水，不干不浇。若浇水过多，就多晒晒太阳，松松土，若盆土还是长时间湿润，那就只能换盆了！ 姬星美人叶子变黄原因：光照不足 姬星美人在阳光充足的环境下会变成蓝色，非常漂亮，但正常情况下会保持绿色，只有少数情况，缺少光照会颜色暗淡。所以你要确定是否是因为缺少光照导致姬星美人叶子发黄。 如果是光照原因导致叶子发黄，那就容易很多，补充光照就好，放在阳光下多晒晒。 姬星美人叶子变黄原因：病虫害 姬星美人叶子发黄可能是病虫害在做怪，仔细观察叶片上有没有出现斑点，或者白色的小虫子，一旦发现及时清理干净。 姬星美人的植株很小，叶片较厚，成簇生长，发生虫害很难发现的。所以要以预防为主。在养护中每个月喷洒一下杀菌药剂。 [图片]一直喜欢姬星美人，袖珍，好养，够萌，不用操心，随便给她点阳光就能出效果，去年10月，掉在地上几个月的姬星美人居然生根活了，于是我把他们换到粗瓶子里养着，不到半年，变成胖妞了，呵呵，好吧，你想胖就胖吧~

吹雪之松锦原产纳米比亚，是一种变异带有白色锦斑的多肉植物。马齿苋科、回欢草属多肉植物，别称回欢草，顶端叶片似莲花展开，叶面厚实，五彩雍华，喜阳，但忌长时间放在烈日下。株高仅5厘米，叶色倒卵形，叶腋间有白色丝状毛，开玫瑰色小花。变异品种叶上有橘红色斑块，更具观赏性。是马齿苋科中唯一被作为多肉植物介绍的一类。在养殖过程中，养护不当会出现吹雪之松锦叶片发皱、烂根现象，接下来一起看看吹雪之松锦发皱原因及怎么解决。 [图片]吹雪之松锦发皱分析 吹雪之松锦皱了大部分是烂根了，水多了就会烂根。换个底部能透水的花盆。把多肉植物拔出来，检查一下根系的情况，把腐烂的根去掉，把多肉植物晾几天，然后再湿土干栽，过一段时间新的根生出来就好了。土壤不干不浇水，浇水一次要浇透(看到水从花盆底部渗出来)，如果花盆下面用了托盘，不要让渗出的水积在托盘里。放在明亮透风的地方。夏天日照时不要让阳光直射，以免灼伤叶片。 [图片]吹雪之松锦养殖事项 1、吹雪之松锦养殖：盆土配制 吹雪之松锦锦为浅根性肉质植物，盆栽土须用腐叶土和粗沙的混合土，盆栽时，盆底要多加瓦片，以便有良好的排水性。 2、吹雪之松锦养殖：光照充足 吹雪之松锦锦喜阳，能在全日照环境下生长最好，但忌长时间放在烈日下，夏季高温强光时适当遮荫。 3、吹雪之松锦养殖：浇水适量 夏季没有明显的休眠期，但要减少浇水，保持盆土干燥，不宜浇水过多否则会导致烂根的现象。 4、吹雪之松锦养殖：温度控制 平常在室内养吹雪之松锦锦，要保持温度在15~28为好，最低温5度、最高温35度是植株忍受的极限。 5、吹雪之松锦养殖：通风良好 不论是养什么植物，通风是很重要的环节，在闷热的夏天，到了夜晚要加强通风。 吹雪之松锦作为观赏植物，适宜用小盆栽种，陈设于窗台、案头、书桌、阳台等处，闲暇之时细细观赏其独特的株型、叶片，从中领悟大自然之神奇，植物之妙趣。

玉树是最好养的多肉吧？很久之前就看见过别人家随意丢都在院子里的土都干得裂缝的玉树，感觉它好坚强！我去年扦插了一枝，没怎么费工夫它就活了。生怕它干枯了，随时都把花盆里装满水，离开一周也照样昂首挺胸，虽说没开花没上色，却长势喜人，枝干比拇指还粗了。后来还切了一枝给同事，也是长得旺盛。 当然在好养的植物都有叶子发黄、发软的时候。那么是什么原因造成的呢？ [图片]玉树叶子发黄、发软原因分析 最常见的玉树叶子发软的原因是因为缺水，一般这种情况及时浇水就可以很快恢复，但是也有一些花友发现自己的玉树是莫名其妙的叶子发软，不知道该如何下手查找原因，下面我们来总结一些常见的排查玉树叶子发软的方法： 1、玉树发黄：水量大 前面我们已经说了，玉树的叶子含水量很大，所以首先检查是不是缺水了。 2、玉树发黄：光照 玉树忌暴晒，检查是不是突然把玉树从室内搬到室外了，叶子被晒蔫了，这种情况应该将玉树及时挪到阴凉的散光处养护。 3、玉树发黄：烂根 玉树还是比较容易烂根的，浇水多了，容易导致烂根，这个可以根据自己的浇水情况来排查，如果烂根，只有挖出来看看根的情况，适当处理重新栽种，如果严重，只能重新扦插了。 4、玉树发黄：通风 玉树需要通风良好的环境，有时候花友们的玉树是在比较闷的环境中，这不利于玉树的生长。 还有诸多原因，比如有换盆后叶子发软的，室内搬到室外暴晒导致叶子变软的等等，花友要结合自己的实际情况来排查。 春夏间可以给玉树换土，夏季到了，玉树移放室外养护，应先放在阴凉处，再移置强光下，放在屋檐下、阳台后口处最佳。平时浇水也不要过多过勤，见盆土表面发干时再浇。到了冬季，玉树就可安心地放在室内养护。 [图片]玉树景天科青锁龙属多肉植物有多个别名燕子掌、厚脸皮、玻璃翠、豆瓣掌等。小型灌木状肉质植物，茎圆柱形，灰绿色，肉质，多分枝，有节。叶对生，扁平肉质，椭圆形，全缘。玉树喜温暖、干燥和阳光充足环境。不耐寒，耐干早，怕积水，忌强光，稍耐阴。生长适温22一27℃。冬季温度不低于7℃。宜肥沃和排水良好的沙质壤上。玉树有“富贡吉祥”、“财源滚滚”等花语，盆栽茎干基部膨大，枝叶肥厚，四季碧绿，叶形奇特，株形庄重，宜于盆栽水养，装饰茶几、案头，翠绿清秀，十分诱人。非常适合家庭点缀。
