[图片]一．养殖的方法 1家庭种的话，可以准备好培育芽苗的培养土，泥土的调配最好是使用园土加上腐叶土、细沙一起按照2:2:1调配，然后要消毒。消毒后的土可以避免苗期病虫害的威胁。 2把采集到的种子放在通风的干燥的地方储存，选择在冬天的12月份种在气温在2到8度的温室里面，到了第二年，种子就会长出芽苗来，到了3月份就可以移到比较大的盆子里面了。也可以在5月份采种子，立刻播种，这样很快就可以发芽了。 3播种之后的屋子内的温度一定要维持在15度到25度。 [图片]4等到小苗都长出来之后，要对温度进行特别的控制为了防止小苗的徒长，而且这个时候要注意光照的补充要充足，白天的温度要在15度，晚上的温度要在8度到10度，要令泥土稍微地干燥。 5等到小苗长出第一片叶子的时候就可以开始分开种了，底下的水要湿透。这个时候的温度就可以在白天维持20度，晚上维持15度左右。还可以适当地在泥土里面施一点已经腐熟的有机肥料促进它的成长。 6等到芽苗长出5片叶子的时候就可以定位种植了，每40株之间的空间要达到1平方米。 二．养殖的注意 1由于这种植物的抵抗能力非常强，所以在它的成长期里面不需要对它进行特殊的管理，不过在它的成长比较旺盛的季节，可以每隔7到10天给它施加一次有机肥料。 2这种植物容易惹来红蜘蛛侵害叶子，可以准备石硫合剂来喷杀红蜘蛛。 3这种植物会容易得半知菌感染，然后生叶斑病，如果不及时救治会引起大片的黑色斑，然后叶片会慢慢地枯黄然后凋零。所以一旦生病，要准备好药水喷叶面。 [图片]

Description: This perennial plant is 1½–3' tall and more or less erect. It is usually unbranched below, while branching occasionally above. The stems are light green or light blue, glabrous, and often glaucous; they are usually terete, although sometimes the stems are narrowly furrowed. Alternate leaves occur along the entire length of these stems, becoming gradually smaller in size as they ascend. These leaves are up to 6" long and 1¼" across, although they are typically about one-half of this size. The leaves are oblong-ovate, oblong-obovate, lanceolate, or ovate in shape, while their margins are either entire (toothless) or sparingly and bluntly toothed. Both lower and upper leaves clasp their stems. The upper leaf surface is medium green to grayish blue, glabrous, and sometimes glaucous, while the lower leaf surface is light green or light grayish blue, glabrous, and sometimes glaucous. A reticulated network of secondary veins is usually visible on the lower surface of each leaf. The central stem terminates in a panicle of flowerheads about ½–1' long and about one-half as much across; smaller panicles of flowers often develop from lateral upper stems and the axils of upper leaves. Each flowerhead is ½–1" across, consisting of 15-30 ray florets that surround a dense head of numerous disk florets. The petaloid rays of the flowerheads are light lavender or light blue-violet (rarely white), widely spreading, and narrowly oblong in shape. The corollas of the disk florets are 3-6 mm. long, tubular in shape, and 5-lobed along their upper rims. During the blooming period, they change in color from whitish yellow to purplish red, eventually turning brown afterwards. The short-triangular lobes of these corollas are erect or ascending. Surrounding the base of each flowerhead, there are glabrous phyllaries (floral bracts) in several series that are erect or appressed together; they are linear-oblong in shape or sometimes wider. These phyllaries are mostly light green or light bluish green; they have either dark green markings at their tips or solitary vertical veins that are dark green. [图片]The branches and peduncles of the panicle are light green or light grayish blue, terete, glabrous, and sometimes glaucous; solitary leafy bracts up to 2" long and ½" occur where the branches divide. The characteristics of these leafy bracts are similar to those of the leaves. The blooming period occurs from late summer to early autumn, lasting about 3-4 weeks for a colony of plants. Afterwards, the florets are replaced by achenes with small tufts of tawny (less often white) hair; they are distributed by the wind. Individual achenes are 2-3 mm. long, narrowly oblongoid-oblanceoloid in shape, slightly flattened, and variably colored (usually some shade of gray or brown with whitish fine ribs). The root system is fibrous and rhizomatous; older plants may develop small woody caudices. Occasionally, clonal offsets are produced from the rhizomes. [图片]Cultivation: The preference is full to partial sun, mesic conditions, and soil containing loam, clay-loam, sandy loam, or some rocky material. This plant usually remains erect while in bloom and it is able to tolerate hot dry weather if it is not too prolonged. The foliage is occasional marred by powdery mildew and other foliar diseases to some extent; good air circulation reduces this vulnerability. Smooth Blue Aster is easy to cultivate in gardens if taller and more aggressive plants are kept away from it. Range & Habitat: The native Smooth Blue Aster occurs occasionally in most counties of Illinois, but it is uncommon or absent in western and SE Illinois (see Distribution Map). Habitats include mesic black soil prairies, hill prairies, savannas, rocky open woodlands, sandy woodlands, woodland edges, thickets, limestone glades, and roadside embankments. Smooth Blue Aster is usually found in higher quality natural areas where the original ground flora is intact. It is sometimes cultivated in gardens because of its attractive foliage and flowerheads. [图片]Faunal Associations: The nectar and pollen of the flowerheads attract honeybees, bumblebees, cuckoo bees (Triepeolus spp., Coelioxys spp.), digger bees (Melissodes spp.), leaf-cutting bees (Megachile spp.), Halictid bees (Agapostemon spp., Halictus spp., Lasioglossum spp.), Andrenid bees (including the oligolectic bee, Andrena asteris), Sphecid wasps, Syrphid flies (Eristalis spp., Helophilus spp., Syrphus spp., Toxomerus spp.), Muscid flies, butterflies, and skippers (see Graenicher). Other insects feed destructively on the leaves, flowerheads, and other parts of Smooth Blue Aster. These species include a leaf beetle (Ophraella pilosa), larvae of a leaf-mining fly (Nemorimyza posticata), larvae of the Papery Blister Gall Midge (Asteromyia laeviana), the Short-winged Meadow Katydid (Conocephalus brevipennis), and caterpillars of a butterfly, the Pearl Crescent (Phyciodes tharos); see Clark et al. (2004), Needham et al. (1928), Felt (1917), Gangwere (1961), and Opler & Krizek (1984). The Insect Table and Moth Table list additional insects that feed on this and other asters (Symphyotrichum spp.). Two upland gamebirds, the Ruffed Grouse and Wild Turkey, feed on both the leaves and seeds of asters. The Tree Sparrow and White-footed Mouse also eat the seeds. The young foliage of these plants is browsed occasionally by various mammalian herbivores, including deer, rabbits, groundhogs, horses, cattle, and sheep. [图片]Photographic Location: The photographs were taken at a restored prairie of Meadowbrook Park in Urbana, Illinois, and at a small restored prairie along a drainage ditch in the same city. Comments: Smooth Blue Aster (Symphyotrichum laeve) has many attractive qualities – they include its adaptability, beautiful flowerheads, attractive foliage, and flowering stems that usually remain erect. It's surprising that this aster is not grown more often in flower gardens. Smooth Blue Aster can be distinguished from other asters (Symphyotrichum spp.) primarily by the lack of hairs on its smooth foliage and stems; its foliage often has grayish or bluish tints. Other asters tend to have leaves that are hairy or rough-textured, while others have stems with lines of hair. Another distinctive characteristic is the lack of petioles – the leaves of Smooth Blue Aster clasp their stems. A scientific synonym of this plant is Aster laevis.

Description: This herbaceous perennial plant is up to 2' tall, branching occasionally to create a bushy appearance. The hairy stems are green initially, but often become brown when the plant matures. The alternate leaves are up to 3" long and ¼" across toward the base of the plant, becoming less than 1" long and 1/8" (3 mm.) across near the flowering stems. They are linear in form and have smooth edges, often with a fine pubescence. The lower leaves usually shrivel and fall off by the time the compound flowers bloom during the fall. These flowers are very numerous and have a daisy-like appearance. Each compound flower is a little less than ½" across, and consists of numerous yellow disk florets, which are surrounded by about 12 white ray florets. There is no noticeable floral scent. There are numerous needle-like green bracts on the flowering stems, giving this plant a heath-like appearance. The little seeds have tufts of white hairs, and are distributed by the wind. The root system is rhizomatous. Cultivation: The preference is full sun and average to dry conditions. The soil can contain significant amounts of loam, clay, or gravelly material; alkaline soil is tolerated. This plant withstands drought. It often spreads vegetatively to form colonies, especially in open disturbed areas. Range & Habitat: The native Heath Aster is found in most counties of Illinois, but it is absent from some counties in the western and SE areas of the state (see Distribution Map). Overall, it is occasional to locally common. Habitats include mesic to dry black soil prairies, gravel prairies, dolomite prairies, hill prairies, savannas, openings in dry rocky forests, limestone glades, areas along roadsides and railroads, and pastures. It can be found in both high quality habitats and disturbed areas. Faunal Associations: A wide variety of insects are attracted to the flowers, including long-tongued bees, short-tongued bees, wasps, flies, butterflies, skippers, moths, beetles, and plant bugs. Bee visitors include honeybees, bumblebees, cuckoo bees, little carpenter bees, leaf-cutting bees, Halictid bees, plasterer bees, and Andrenid bees. Wasp visitors include thread-waisted wasps, bee wolves, spider wasps, sand wasps, paper wasps, Ichneumonid wasps, and Braconid wasps. Among the flies, are such visitors as bee flies, Syrphid flies, thick-headed flies, Tachinid flies, Muscid flies, and others. Various insects suck juices from the plant, including aphids, lace bugs, and plant bugs. The caterpillars of the butterfly Chlosyne nycteis (Silvery Checkerspot) feed on the foliage or flowers, as does the caterpillars of many moth species (see Moth Table). Wild Turkeys nibble on the seeds and foliage to a limited extent. Mammalian herbivores, including the White-Tailed Deer, Cottontail Rabbit, and various kinds of livestock, also feed on the tender growth of young plants occasionally, but are less likely to bother mature plants later in the year. [图片]Photographic Location: The photographs were taken at Loda Cemetery Prairie in Iroquois County, Illinois. Comments: The Heath Aster has a wide distribution, and there is some variability in regards to its size and appearance across different locations. Sometimes it will hybridize with other species of asters, such as Symphyotrichum novae-angliae. The Heath Aster differs from other asters with small white flowerheads primarily by its short, narrow leaves (never more than 3" long and ¼" across). Also, its flowerheads tend to be smaller in size and they have fewer ray florets (about 12) than many other aster species. A scientific synonym of this plant is Aster ericoides.

Description: This herbaceous vine is a summer annual about 2-6' long that branches occasionally. Its slender stems can climb by twining about adjacent vegetation; they are finely pubescent. Alternate trifoliate leaves occur at intervals along the stems. Each leaflet is about 1" long and 1/3" (8 mm.) across; it is oblong-lanceolate, smooth along the margins, and finely pubescent on both the upper and lower sides. Each trifoliate leaf has a long petiole about 1-2" long that is also finely pubescent; there is a pair of small lanceolate bracts at the base of each petiole. No tendrils are produced by this vine. At the base of the middle to upper leaves, a slender flowering stalk (peduncle) about 1-4" long is occasionally produced. Each stalk terminates in a dense cluster of 1-6 small flowers; usually only one flower in a cluster is in bloom at a time. Each flower is up to ¼" long; it has a pale pink to purplish pink corolla. This corolla has a typical pea-like structure that consists of a standard, keel, and enclosing wings. However, the narrow keel and its wings are somewhat unusual in that they curve upward in front of the standard, instead of remaining straight. This characteristic distinguishes the Strophostyles genus from many other members of the Bean family. The short tubular calyx of each flower is light green to purple and finely pubescent; it has 4-5 shallow teeth along its rim and a pair of small bracts (bracteoles) at its base. The pedicel of each flower is very short. The blooming period occurs from late summer into the fall and lasts about 1-2 months. Each flower is short-lived and lacks any noticeable floral scent. A fertile flower is replaced by a cylindrical seedpod about 1–1½" long that has a beaked outer tip. This seedpod is initially green, but becomes dark brown with maturity; it is finely pubescent to conspicuously hairy. Each seedpod contains a few large seeds that are oblongoid in shape; they become dark, shiny, and hairless with maturity. The root system consists of a taproot. This vine spreads by reseeding itself. Cultivation: The preference is full or partial sun, mesic to dry conditions, and sandy soil. Conventional garden soil containing loam or clay-loam is tolerated if there is not too much competition from taller plants. The seeds may remain in the ground for several years before they germinate; scarification of the seeds can speed up this process. The roots add nitrogen to the soil by forming a symbiotic association with rhizobial bacteria. Range & Habitat: The native Small Fuzzy Bean occurs occasionally in southern Illinois and in sandy areas of central and northern Illinois, otherwise it is uncommon or absent (see Distribution Map). Habitats include open rocky woodlands, open sandy woodlands, sandy savannas, glades, thickets, sand prairies, and sandy fields. This species is usually found in rather dry areas with sparse ground vegetation. Occasional wildfires are probably beneficial in removing competition from woody vegetation and other tall plants. [图片]Faunal Associations: The nectar of the flowers occasionally attracts bees, including bumblebees, Leaf-Cutting bees (Megachile spp.), and Dagger bees (Calliopsis spp.). The extra-floral nectaries attract ants and Halictid bees. The caterpillars of the following skippers occasionally feed on the foliage of Strophostyles spp. (Fuzzy Beans): Epargyreus clarus (Silver-Spotted Skipper), Thorybes bathyllus (Southern Cloudywing), and Urbanus proteus (Long-tailed Skipper). Some leaf beetles feed on the foliage as well, including Cerotoma trifurcata (Bean Leaf Beetle), Sumitrosis ancoroides, and Sumitrosis pallescens; the larvae of the latter two species are leaf-miners. The Mourning Dove and Bobwhite Quail eat the seeds of Fuzzy Beans, while the foliage is readily eaten by cattle, deer, and other mammalian herbivores. Photographic Location: The wildflower garden of the webmaster in Urbana, Illinois. The dainty foliage of Aster oblongifolius (Aromatic Aster) can be observed in the background of the photographed trifoliate leaf. [图片]Comments: This rather ordinary-looking vine has small flowers that are short-lived. Other common names for this species are Small Wild Bean and Small Woolly Bean. Two other vines in this genus that occur in Illinois are the following: Strophostyles helvola (Large Fuzzy Bean) and Strophostyles umbellata (Perennial Fuzzy Bean). As the common name implies, Large Fuzzy Bean is a more robust vine with longer stems and larger leaves; the leaves of this species are sometimes lobed. It is also a summer annual, but prefers more moist habitats. Similarly, the Perennial Fuzzy Bean is more robust with longer stems and larger leaves; this perennial vine is restricted to southern Illinois. These latter two species have slightly larger flowers (greater than ¼" in length) than the Small Fuzzy Bean (up to ¼" in length); they all have keels on their flowers that curve upward and their seedpods are finely pubescent to conspicuously hairy. While the mature seeds of Small Fuzzy Bean are shiny and hairless, the mature seeds of Large Fuzzy Bean and Perennial Fuzzy Bean are usually mealy-pubescent.

Description: This herbaceous perennial plant is ½–2½' tall and usually unbranched. The central stem is 4-angled, usually with scattered hairs along the ridges, but not the sides (see Stem Photo). The opposite leaves are up to 3½" long and 1"Whorls of Flowers across. They are usually lanceolate or narrowly ovate, with serrate or crenate margins. The petioles of the lower leaves are about ¼" or slightly longer, while the upper leaves have shorter petioles or are sessile. Both the upper and lower surfaces of the leaves are hairless or nearly so – if hairs are present, they are most likely to occur along the lower mid-vein of the leaves. The central stem terminates in a spike-like inflorescence that has whorls of flowers at intervals along its length. This inflorescence can vary from 2-8" in length. The tubular corolla of each flower is about 1/3" long and divided into 2 lips. The hairy upper lip functions as a protective hood, while the lower lip is divided into 3 lobes (a central lobe and two smaller side lobes), which functions as a landing pad for visiting insects. The flowers are light pink or white, often with rosy pink splotches within the throat. The green calyx is hairless and at least half as long as the tube of the corolla (not including the lips). It is divided into 5 triangular segments that curl outward as the ovaries mature. The blooming period occurs during the summer and lasts about 1-2 months. Each flower is replaced by 4 black nutlets that are oblong in shape. The root system consists of a taproot and rhizomes. This plant often forms vegetative colonies, like many other members of the Mint family. Cultivation: The preference is partial sun and moist conditions. This plant also tolerates light shade and full sun. The soil should contain sufficient organic material to retain moisture. If this plant dries out, the leaves have a tendency to turn yellow or brown, and the entire plant may die. Range & Habitat: Smooth Hedge Nettle occurs in most counties of Illinois (see Distribution Map), where it is native. This plant is occasional in southern and central Illinois, but uncommon or absent in the northern counties. Habitats include ravines in floodplain forests, moist meadows along rivers or woodlands, thickets, and various kinds of wetlands, including swamps, seeps, and ditches. It can be found in either high quality habitats or rather degraded sites. Faunal Associations: Primarily long-tongued bees pollinate the flowers, where they seek nectar primarily. Short-tongued bees sometimes collect pollen, while flower flies feed on the pollen, but they are not very effective pollinators. Occasionally butterflies or skippers may visit the flowers, but they aren't very effective at pollinating the flowers either. The bitter foliage of this and other Stachys spp. is not often consumed by mammalian herbivores. [图片]Photographic Location: A swampy area of Busey Woods in Urbana, Illinois. Comments: This is a typical member of the Mint family. It is easy to overlook, because this Hedge Nettle sp. tends to be rather small-sized and non-descript, almost looking like a lanky Prunella vulgaris (Self-Heal) at first glance. Identifying Smooth Hedge Nettle correctly can be rather tricky, so here are some of the key features to look for: 1) The calyx is hairless; 2) the petioles of the lower leaves are usually ¼" or longer, and 3) there are hairs on the ridges of the 4-angled central stem, but not on the sides. There is also a hairy form of this plant, referred to as Stachys tenuifolia hispida by some authorities and Stachys hispida by others, that also occurs in Illinois. It has foliage that is more hairy, and there are also some hairs along the edges of the calyx of each flower. However, it is similar to Smooth Hedge Nettle in that the central stem has hairs along the ridges, but not on the sides.

Description: This perennial plant is about 1½-3' tall and either unbranched or sparingly so. The 4-angled central stem is light green to dark purple and covered with fine hairs on all sides. The opposite leaves are up to 4" long and 1¾" across. They are lanceolate-oblong to ovate-oblong in shape, finely serrated along their margins, and either sessile against the stem or with short petioles (less than 1/3" or 8 mm. in length). The upper leaf surface is medium to dark green and finely short-hairy, while the lower surface is light green and finely hairy, especially along the lower sides of major veins. The foliage has an unpleasant bitter smell. The central stem terminates in a spike of flowers about 4-8" long. This spike consists of about 4-12 whorls of flowers, each whorl having several flowers. Each flower is about ½" long, consisting of a short-tubular corolla with 2 lips, a short-tubular calyx with 5 narrow triangular teeth, and the inserted reproductive organs. The corolla is white to light pink with splotches of rosy pink. The upper lip of the corolla is undivided and hairy along its upper surface, while the lower lip is divided into 3 lobes (a central lobe and 2 smaller side lobes). The calyx is green to purplish green and finely hairy. The calyx is green or purplish green; its teeth extend to more than one-half of the length of the corolla tube (excluding the length of the lips). The central stalk of the floral spike is green to dark purple and covered with fine hairs on all sides. The blooming period occurs during the summer and lasts about 1-2 months. Sometimes the flowers have a mild fragrance. After the blooming period, the flowers are replaced by open seed capsules; each capsule contains 4 small nutlets. The root system is rhizomatous and tuberous. Hairy Hedge Nettle often forms clonal colonies of varying size. Cultivation: The preference is full sun to light shade, moist conditions, and soil that is loamy or sandy. The foliage is rarely bothered by either disease or insects. Range & Habitat: The native Hairy Hedge Nettle occurs primarily in central and northern Illinois, where it is occasional. In southern Illinois, it is either absent or uncommon (see Distribution Map). Habitats include moist prairies, edges of marshes, moist meadows in wooded areas, borders of bottomland woodlands, soggy thickets, prairie swales, roadside ditches, edges of fields, and fence rows. Hairy Hedge Nettle can occur in either sandy or non-sandy habitats that are variable in their level of disturbance. [图片]Faunal Associations: The flowers are visited by nectar-seeking bees primarily, including bumblebees, leaf-cutting bees (Megachile spp.), digger bees (Melissodes spp.), little carpenter bees (Ceratina spp.), and Anthophorid bees (Anthophora spp.). Sometimes the flowers are visited by butterflies, skippers, and moths, but they are not very effective at cross-pollination. Small bees also visit the flowers to collect pollen. The seeds of Stachys spp. (Hedge Nettles) and other members of the Mint family are eaten by Sehirus cinctus (White-Margined Burrower Bug). Because the foliage is bitter and hairy, it is not favored as a food source by mammalian herbivores. Photographic Location: The photograph was taken in an overgrown moist area between an abandoned railroad and a roadside in Champaign County, Illinois. [图片]Comments: This plant has an unsettled taxonomic history. At the present time, I prefer to use the scientific name Stachys palustris arenicola from the Field Guide to Indiana Wildflowers (2000) by Kay Yatskievych. Older authorities, such as A. G. Jones or Britton & Brown, called this species Stachys arenicola. In contrast, Mohlenbrock (1986, 2002) probably refers to this species as a variety of Stachys palustris or Stachys pilosa. Hairy Hedge Nettle can be distinguished from other Stachys spp. (Hedge Nettles) by the presence of fine hairs on all 4 sides of its central stem, the general hairiness of its leaves, the absence of petioles exceeding 1/3" (8 mm.) in length, the length of its toothed calyx in relation to the corolla tube (exceeding one-half of its length), and the shape of its calyx teeth. All of the Hedge Nettles differ from the similar Teucrium canadense (American Germander) by having flowers with well-defined upper lips.

[图片]土壤的选择 在我国的绝大部分地区都能找到紫花地丁的影子。从这不难看出它有着极强的环境适应能力，同时这也表明它对于栽植土的要求并不苛刻，一般的栽植土都可以满足它的生长需求。 但是它怕水淹，这就要求培植土不能有积水，必须有较好的排水能力。 此外，若是在盆栽，我们可以更方便的调整选取培植土。 选择肥力相对较高、透气性相对较强的培植土可以让它生长的更好。 盆栽的方法 盆栽首先要有盆，所用花盆的大小可以根据种植的量自行定夺，但花盆底部要有排水孔。 将准备好的培植土用花盆盛好，并将土表铲平。此时要注意不能将花盆全部盛满，要留出一定的高度，这样之后浇水的时候就不用担心水会溢出了。 取一个大水盆盛好清水，将花盆浸入水中，让水从花盆底部的排水孔慢慢渗入培植土中。等到盆内培植土的表面变色，将花盆取出，并将盆底和盆壁上的水擦干。 然后把种子均匀的放在土表。此时要注意种距适中，还要轻拿轻放，保证种子不会受到损伤。 再用一层培植土覆盖在种子上。要注意盖的不能太厚，1cm~2cm即可。 最后将花盆放在光线柔弱的房间内，及时补充水分，紫花地丁很快就会发芽了。 地栽的方法 较于其它种子，紫花地丁的种子非常细小，比起撒播最好选择穴播的方式播种。 首先需要选择一个种植地点。最好将它种在向阳的缓坡上，若没有条件也可以选择其它地方种植，因为它有较强的适应能力，可以适应不同的环境。 但是不能将它种在低洼中，因为低洼会积水，容易导致它的根部腐烂。 在播种前先整地，深翻土壤30cm以上。 然后是挖穴，再将种子撒到小穴中。穴不能太深，一个洞穴中也不能种太多种子，2~3粒即可。 最后耙平土面，使种子完全没入土中，浇水保墒，方便出苗。 [图片]

[图片]繁殖的时间 这种小花的繁殖基本都要靠种子，进行操作的时间也不是很严格，但不不能在盛夏。其他三个季节都是可以播种的，春秋的时候温度正适合小花发芽，温度高的话种子很可能进入休眠，不能正常繁殖。 繁殖的步骤 首先要选择合适的土，这种花要求土的PH不能太高，最好能在5-5.5这个范围内、对土质的要求不是很多，若是松散一点的腐殖土更好了，在种植之前，要添加一点基础肥料，这样才能保证在生长初期，给它们足够的营养供应。 种子萌芽的这个阶段也是需要光的，所以播种之后种子上面放的蛭石要薄一点。而且播种之前还要把种子和基质都充分的消毒。土壤里面要有一定的水分，但是水分不能太多，水太多会导致种子呼吸不畅，不能好好呼吸。 播种好之后要适当的遮阳，不能让太阳直接照到种子，大约一个月的时间就可以在花盆中了，等根系稳定之后就可以正常养护了。 [图片]繁殖后的养护 移植到花盆半个月之后，就要开始施肥，直到开花之前，每周一次就可以。开花之前一定要加用磷含量比较多的肥料。肥的浓度不宜过高，不然会烧坏植株。还要注意一点，一定要注意通风透气，栽培的密度也是不能过大，如果花开的过早，要摘掉这些花，不然植株可能会被早开的花吸收掉部分营养，植株就无法正常生长。 [图片]

[图片]种植方法 我们都知道，这种植物的最初的生长，一定是从种子开始的，也就是播种，也有采用块根繁殖的，不过这种方式不太常见，所以我们就只以播种为例进行详细解释。 具体步骤 采集种子：这个比较简单，选择那些黑色的、摸起来不软的种子采收下来就可以了。不过，并不是采集下下之后立即就可以使用，而是要先放在遮阴、通风的地方保存一段时间。大概在第二年的四月末或者五月初，就可以拿出来播种了。 基质的选择：这一步是非常重要的，直接影响种子的成活率。选择的原则有疏松、含有的腐殖质丰富、深厚等等，可以将一些壤土跟砂土混合起来。 种子的处理：在正式播种之前，我们需要将种子与新高脂膜混合搅拌一些，以加强其呼吸的强度，预防病毒感染，提高其发芽率。 正式播种：我们可以采取条播或者散播的方法播种。播好之后，需要我们再覆盖上一层拌有草木灰的土壤，并且浇透水。 后期处理：播种完成浇过水之后，以后也要注重使土保持在湿润状态中，最好每次浇水要浇得透一些。然后就是等待其发芽了。等到它们出苗之后，我们要追施一些稀薄的肥水，这样可以加快幼苗的成长发育速度，不过注意浓度不要太高。等到小苗长到五到六寸高的时候，就可以选择那些看起来比较健壮的苗，把它移栽在花盆或者花坛之中。

[图片]一.培植土不合适 它害怕培植土积水，如果植株不开花，很有可能是培植土品质不达标，如果不改变，还会出现落叶等情况，甚至影响植株健康生长。以在选择培植土时，应该选择质地疏松、易于排水的沙质土壤。 可以选择壤土两份，混合一份泥炭土和一份沙子制成培植土，用于养殖。顺便一提，我们可以在配置培植土的过程中掺加一些基肥来增加它的肥力。如果直接使用培植土种植，可以稍微在培植土中加入沙子，使它疏松。 [图片]二.温度不合适 它对温度要求非常低，但是在比较特殊的环境下，温度不适还是有可能导致植株不开花、黄叶等现象。一般而言，它可以在春季和秋季这两个季节长得很好。但天气太过寒冷的冬季，可能会导致植物停止生长，所以需要进行一定的保暖。 三.水肥供给不适合 这种植物水分要求不高，肥料的需求也不高，但是如果水肥出现问题，也很容易造成植物不开花。在刚刚定植的时候，需要时刻保持培植土的湿润，并且每隔十天需要施用稀薄的液肥。之后在生长期就可以改成3-5天进行一次浇水，不需要太过频繁，肥料的需求也不高，可以每隔一两个月进行一次。如果不开花，可以尝试增加培植土营养，并防止供水过多导致根缺氧。 [图片]四.光照不适合 它有比较强的环境适应能力，可以在各种光照条件下生长，但是如果长时间光照达不到标准，也很可能造成植株不开花，所以需要进行补充光照，以防影响植物的正常生长。同时，在低温条件下也应当适当增加光照，保证植株生长。 五.营养太分散 由于这种植物生长快，为了防止此类情况发生，需要进行修剪，第一次修剪应当在定植之后。还可以摘心，促使其多多生长分枝。如果不开花，可以适当的进行修剪。 [图片]
