麒麟掌是一种较为常见的多肉植物,它常常被放在室内进行培养,它的叶片呈鸡冠的样子,里面有白色的汁液,我们在日常养护的时候,要知道,麒麟掌是有毒的,我们千万不能误食了这些汁液,如果中毒的话会出现头晕呕吐的症状,要及时的进行救治。 [图片]光照 麒麟掌喜光,稍耐阴,不宜过阴和曝晒。5月初出房后,先置于阴棚下7~10天,再放到阳光充足处养护。光照不足易导致变态茎徒长而成为柱状茎。尤其是在生长季节里更要保证充足的光照,切不可久置室内观赏。冬季虽已休眠,但植株还要进行光合作用,以维持基本的生命活动,因此亦应放置在阳光充足的场所,否则会使叶片发黄脱落。 水分 麒麟掌比较耐旱。平时浇水以宁干勿湿为原则。当盆土干硬发白、叩击盆綮听到清脆的响声后浇透水。冬季浇水比平时还要减少,在温度为15~18℃的室内,每10天左右浇一次透水即可。浇水过多不但容易发生“返祖”现象,还会导致根系窒息而死。 [图片]肥料 麒麟掌不太喜肥,供肥原则是宁少勿多,宁淡勿浓。盆土可用腐叶土、煤球渣、园土各1/3混匀配成,上盆时可少放些粉碎的固体肥料作基肥。生长季节每月施一次15%左右充分腐熟的矾肥水。施肥时切忌生肥、浓肥,否则易致烂根、落叶。冬季休眠时可停肥,至翌春开始生长时再逐渐恢复正常的供肥水平。 [图片]温度 麒麟掌不耐寒,生长适温22~28℃,30℃对其生长不利,35℃以上即进入休眠。一般在霜降前第1次寒流未来时就应入室。开始应注意室内通风,让其逐渐适应室内小气候。冬季即使天气暖和,也不可搬到室外晒太阳。冬季室温如能保持15℃以上可保证叶片不落;如已落叶,只要温度在7℃以上就可以安全越冬

玉扇又叫截形十二卷,产于南非,是一种长方形厚叶多肉植物,也是十二卷属中较为难养的品种。玉扇的形态很奇特,淡蓝灰色的长圆形叶片排列成两列,直立稍向内弯,顶部是稍凹陷的褐绿色截面。表面较为粗糙,有小疣状突起,有些叶片截面上有灰白色透明状花纹的品种更为美丽。 [图片]这种植物喜欢生活在温暖湿润的地方,我们在它生长的时候可以多进行喷雾处理,但是也不能让叶片上长时间有水珠,因为太阳光线照在叶片上的话,会让水珠吸取大量的能量,这样会灼伤叶片的。 我们可以用塑料袋吧玉扇扎起来,玉扇在进行光合作用的时候就会产生一定的水分,这样会让植物产生的水分保持住,在这样的环境下植物的叶片会比较靓丽,纹路也会非常的清晰。在进入玉扇生长期之后,我们需要用稀释的肥料进行施肥,一个月可以有两次,施肥以后放在阴凉通风的地方,减少太阳的暴晒导致温度升高引起植株受伤。 [图片]玉扇的换盆工作一般都是在春季进行的,我们在换盆的时候要把根部一些老的、腐烂的根茎给修剪干净,我们给玉扇用的土壤最好是有一定肥力的,还要同时具有比较好的排水作用,这样会防止根部腐烂。像我们小区的园土配合泥塘土都是可以的,有条件的朋友我们还可以在盆土里混合一些鱼骨或者是瓜果壳作为肥料也是极好的。 [图片]玉扇的光照我们也是要注意的,因为充足的光照可以帮助玉扇保持生长温度,夏季的时候在中午的时候我们要注意庇荫,因为温度太高会造成叶片蒸发加快,容易出现黄叶,冬天呢中午的太阳一定不能错过,这大概是一天中最暖和的时候,平时就要放在屋里,保持温度。 玉扇还需要注意修剪和病虫害,一些长的快的或者是枯叶都要尽快清理掉,减少养分的流失,同时我们要做好虫害的防护,可以用辣椒水或者是大蒜水,每个月浇一次,也能有效防止虫害的入侵。玉扇的品种有很多,比如蝙蝠侠、白亚玉扇、猛犸等等,我们可以选择自己喜欢的植物来养护呢。

宝草是百合科多肉植物,原产于南非。叶形叶色较美,有一定的观赏价值。因此很多朋友喜欢在家居养殖一些,那宝草怎么养殖呢?一起了解下宝草养殖方法吧。 [图片]土壤的选择很重要,由于多肉类植物都比较喜欢肥沃透气性良好的沙质土壤,不过宝草对土壤的要求并不高,由于植株矮小,根系很浅,应采用比较小的浅盆栽植,所以盆栽的土壤底部可以使用大量的颗粒铺垫,增加透水透气性,然后再用肥沃的壤土和粗砂混合的营养土覆盖种植。 温度也是影响宝草生长的因素,宝草喜温暖湿润的半阴环境,耐干旱但是非常忌惮炎热的环境,也不耐严寒,适宜生长的温度是20-25摄氏度。尤其是夏季时,如果温度超过30摄氏度就会进入休眠期,若温度超过32摄氏度并且通风不良的话,宝草的嫩叶容易腐烂;在冬季温度不能低于10摄氏度,最好是维持在12摄氏度。 [图片]光照也不可或缺,宝草对光照比较敏感,如果光照太强植株就会生长不良,颜色变成浅红色,色调会变得稍微暗些,最好把植株置于半阴处,这样的植株会呈碧绿透明状,宛如晶莹翡翠,观赏性非常强。在春秋两季,光照时间在4个小时左右就可以,如果光照时间太长会降低植株的美观性,严重会晒伤叶片,特别是夏季的休眠期,一定要放在阴凉通风的地方养护。 浇水对宝草的影响非常大,尤其是夏季。宝草是非常适应水量短缺环境的植物,它的叶子非常肥厚,能够储存非常多的水分,所以在养殖的时候一定要注意浇水的量,不要太勤于浇水。在生长季可以两三天浇一次,只要保持盆土稍稍湿润就可以,在夏季休眠期就不需要勤浇水了,只要经常朝植株周围喷水监督温度和增加周围的湿度就可以。 [图片]宝草对肥料的需求不高,但是在旺盛的生长季还有要适量的追肥,这样能够是宝草更好的生长,施肥最好是以磷钾肥为主的稀释后的肥液,施肥时注意不要将肥液滴洒在叶片上,否则会在叶片上出现黄斑,甚至会腐烂。如果温度太高或者太低就不要施肥了,因为植株吸收不了堆积造成肥害。

珍珠吊兰叶形夜色较美,呈匍匐生长状,可悬挂呈垂吊状,具有很高的观赏价值,也是人气较旺盛的多肉植物品种之一。一粒粒圆润的、肥厚的圆心形叶片,似一串串风铃在风中摇曳,这就是它的叶子。因叶互生,生长较疏,圆心形,深绿色,肥厚多汁,似珠子,故有“佛串珠”、“佛珠"、”绿葡萄“、”绿之铃“之美称。还有人称它为”佛珠吊兰“、”情人泪"。它的茎纤细,头状花序,顶生,长3~4厘米,呈弯钩形,花白色或褐色,花蕾是红色的细条。 [图片]土壤介质 在盆栽花卉中,培养土的配制比例如下,一般花草:腐殖质土30 %、园土50%、河沙20%;木本花卉:腐殖质土40%、园土50%、河沙10%;播种用土:腐殖质土50%、园土30%、河沙20%;温室花卉:腐殖质土40%、园土40%、河沙20%。 培养土一般多以腐殖质土和菜园土作为基本材料,再配合其他物质配制而成。其他物质主要有山泥或塘泥、糠灰、黄沙、火屑、厩肥等。此外,还有瓦片、破盆片,用于盆底垫孔以利排水通气。腐殖质土制作方法比较简单,一般按自己培植盆花多少准备泥盆、缸或在室外泥地挖坑,底部放入一层菜园土,再将日常的一些生活垃圾如菜皮、瓜果皮、豆麦皮及各种鲜嫩草、树叶等植物残渣放在园土上面,同时放入鸡鸭等家禽粪便,浇一些淘米水、鱼腥水或人畜粪尿水,上面再加一些菜园土,这样一层土一层肥水堆积多层,盆口或坑口加盖(泥土也可以)封住。经过2至3个月的发酵腐熟后,取出在太阳下曝晒,便成了良好的腐殖质土。一般情况下,这种土必须充分腐熟才好使用。腐殖质土是大部分盆栽花卉上盆和翻盆的主要用土。菜园土即普通的栽培土,因经常施肥耕作,肥力较高,富含有机质,团粒结构好,是培养土的主要成分。用作栽培月季、石榴及草花效果良好。缺点是表层易板结,通气透水性差,不易单独使用,而应掺入一些其他成分配制后使用。 在大量需要培养土栽培花卉时,制作堆肥土也是一种切实可行的办法。它利用枯枝、落叶、青草、果皮、粪便、毛骨等为原料加上换盆旧土、炉灰、园土共同堆积,往上面浇灌人畜粪水,最后再在四周和上面覆盖园土。经过4至5个月的贮放让其发酵腐烂,然后打碎过筛即为肥土。堆肥土与沙土各一半混合使用,既肥沃又利于排水,如用堆肥与泥炭土混合种兰花、山荷花、君子兰、米兰、杜鹃等花木,效果很好。 [图片]现将常见盆栽花卉培养土配方介绍如下: 用于文竹、吊兰的培养土,要求排水透气性能好,宜用园土或塘泥60%、沙10%、糠灰30%配制;用于梅花、海棠、石榴等花木的培养土,用腐殖质土35%、塘泥35%、沙15%、糠灰15%配制后加少量骨粉;用于茶花、含笑、杜鹃等的培养土,可选用腐殖质土或山泥、焦泥灰、沙配制而成的腐殖质土40%、山泥30%、焦泥灰10%、沙20%配制后,再加少量骨粉等;用于菊花、大丽花和一般温室草花等培养土,用腐殖质土30%、塘泥4 0%、园土30%配制以后,再以上述混合物的70%加糠灰30%,加少量骨粉、石灰等混合,使土壤酸碱性适中;用于柏树、南天竹一类的培养土,用山泥45%、腐殖质与焦泥灰35%、沙20%配制而成;室内观叶植物培养土,用2份泥炭、1份蛭石、1份珍珠岩或采用1份泥炭、1 份珍珠岩、1份树皮配制即可。 吊兰盆栽常用腐叶土或泥炭土、园土和河沙等量混合并加少量基肥作为基质。每2—3年换盆一次,重新调制培养土。其肉质根贮水组织发达,抗旱力较强,但3—9月生长旺期需水量较大,要经常浇水及喷雾,秋后逐渐减少浇水量,以提高植株抗寒能力。生长旺期每月施两次稀薄液肥。肥料以氮肥为主,但金心和金边品种不宜施氮肥过量,否则叶片的线斑会变得不明显。吊兰不易发生病虫害,但如盆土积水且通风不良,除会导致烂根外,也可能会发生根腐病,应注意喷药防治。 管理养护 栽培中浇水应宁干勿湿。天气干燥时可以多向叶、蔓喷水以弥补水分的不足,保持珠体的青翠饱满。忌荫蔽、忌高温高湿。较喜半阴,暴晒可能灼伤珠体,光线过弱则生长不强。 珍珠吊兰主要受:蜗牛、蚜虫、吹绵蚧和煤烟病,茎腐病的危害。 [图片]珍珠吊兰在栽培中注意以下几点: 1、由于叶肉质,多汁,故耐旱。 2、植株根系很浅,可浅盆栽植。一般用瓦片垫底孔,并铺上一层煤渣或粗沙以增加透气和滤水性(尤其是常用的塑料盆栽植的情况下),土壤最好用腐叶土(秋冬树木的落叶拌入一定量的碎土,拌入一定沙子(土、沙比约为1:3左右)。 3、性喜温暖湿润,较耐寒(江淮地区栽培时可耐0℃的低温),耐高温,最适温度为20℃~28℃左右。高温和低温时都生长缓慢,在高温环境中几乎休眠,应少浇水施肥,否则易腐烂,如果开始腐烂了,要立即剪掉腐烂处,把健康的部分进行扦插,否则很快全部烂掉。这也是栽培成功的关键之一。 4、春秋季应"薄肥勤施",常在叶面喷施1-3‰的氮肥和磷酸二氢钾有利于使它更加翠绿肥大,提高观赏价值。 5、很少有病虫害,春季蚜虫是其一,及时抹去或喷1500倍氧化乐果杀灭;夏秋季的螨虫为次,需用1000倍三氯杀螨醇杀灭。注意通风和增加叶面湿度,可减少感染螨虫。 6、夏季容易烂根,浇水不宜太频繁,需用小喷壶浇灌。

The garden strawberry (or simply strawberry; Fragaria × ananassa) is a widely grown hybrid species of the genus Fragaria, collectively known as the strawberries, which are cultivated worldwide for their fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in such prepared foods as jam, juice, pies, ice cream, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in products such as candy, soap, lip gloss, perfume, and many others. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of Fragaria virginiana from eastern North America and Fragaria chiloensis, which was brought from Chile by Amédée-François Frézier in 1714. Cultivars of Fragaria × ananassa have replaced, in commercial production, the woodland strawberry (Fragaria vesca), which was the first strawberry species cultivated in the early 17th century. The strawberry is not, from a botanical point of view, a berry. Technically, it is an aggregate accessory fruit, meaning that the fleshy part is derived not from the plant's ovaries but from the receptacle that holds the ovaries. Each apparent "seed" (achene) on the outside of the fruit is actually one of the ovaries of the flower, with a seed inside it. [图片]*How to grow? 1. DECIDE WHERE TO GROW YOUR STRAWBERRIES Get them some sun on the balcony, rooftop, patio or doorstep. And even if you live in an apartment, condo, townhouse, or small home, you can grow berries in a container on your balcony, rooftop, patio, or even doorstep. If your horizontal space is limited, consider growing strawberries in a hanging basket or stacked planter, which will allow you to take advantage of vertical growing space as the strawberry plants tumble out over the sides. By home-growing your own berries, you will also be helping the environment, since commercially grown strawberries use wasteful amounts of water, chemical fertilizers, and some of the worst pesticides imaginable, not to mention the environmental cost of shipping them for hundreds or thousands of miles. A sunny spot outside your home is the best place to grow strawberries, though you can get a partial crop with less than a half day of direct sunlight. For shadier spots, try planting Alpine strawberries (available from vegetable seed catalogs and online nurseries), which take more patience but ultimately produce delicious fruit. 2. CHOOSE A CONTAINER FOR THEM Give your plants enough room to grow. Whether you choose a container made of clay, plastic, wood, or other material, make sure it has a soil depth of at least 12-14 inches to give the plants’ root systems space to grow. How many plants you can fit in will depend upon the width of the container, since you should space plants about 10-12 inches apart to allow them to spread horizontally. [图片]3. FILL THE CONTAINER WITH SOIL THAT MAKES STRAWBERRIES HAPPY Strawberries like room! Strawberries like deep, loamy soil that drains well. This means that it should contain plenty of organic matter (such as compost, shredded bark or peat moss) as well as some sand or grit. Most potting soil mixes sold at nurseries will be sufficient, and if you have access to compost, sprinkle an inch or so on top. Be sure the container has drainage holes in the bottom. Before planting, buy a small bag of organic fertilizer from your nursery, mix it into your soil, and water this down. You can ask your nursery to recommend the right fertilizer for your soil type and region, but in general, strawberries like plenty of nitrogen plus balanced amounts of the other major nutrients. A 10-10-10 fertilizer is not excessive, especially since organic fertilizers have a slower release time. 4. GET YOUR STRAWBERRY PLANTS Want your strawberries this year, or can you wait? Your next step is to find some plants and put them in the soil. There are two main kinds of strawberries available: “June-bearing” plants that will bear in spring or early summer, and “Everbearing” or day-neutral varieties that can bear from early summer right up until your first frost. While June-bearing varieties can take a year to establish (you normally plant them now for next year’s harvest), everbearing plants can give you fruit the very first year and may allow you to extend your harvest over a period of weeks or months. There are many great varieties of strawberries out there and your local nursery should be able to recommend some good ones for the climate in your area. Sequoia and Chandler are the two sweetest berries I have ever tasted, while Seascape, Honeoye, Quinalt, Tristar, and Allstar have proven themselves in multiple climates. 5. CARE FOR YOUR PLANTS AND ENJOY For optimum production, keep your strawberry plants well watered throughout the growing season. Plants should continue to be productive for at least 2-3 years, but will need to be replaced thereafter. To renovate June-bearing plants for next year, trim off their old leaves, making sure not to damage the center stalk (crown) of the plant. Everbearers do not need this trimming, but all plants should be given some top-dressed fertilizer again after fruiting. I wish you the best of success in growing your own berries! R.J.

月兔耳,原产非洲马达加斯加岛。喜温暖干燥和阳光充足环境。植株被满绒毛,肉质叶片,形似兔耳。叶片边缘着生深褐色斑纹,酷似熊猫,故又有熊猫植物的美称。常用于于盆栽观赏,用于居室、书桌及案几上进行装饰,效果较好,乐趣无穷。 [图片]土壤:以肥沃疏松的沙质壤土为佳。 水分:浇水不能过多和过少,两者都会导致叶片的脱落。 日照:喜阳光充足的环境,夏季要适当遮荫,不能过于荫蔽。 肥料:褐斑伽蓝生长快,每月可施肥一次。 温度:喜温暖,冬季温度不能低于10度。 月兔耳应养在全日照的阳光房里。生长期需保持土壤微湿,避免积水。土壤可用了煤渣混合泥炭、少量珍珠岩,比例大概6:3:1。月兔耳在盆土干燥的情况下能耐零下2℃左右的低温,是室内的温度,非露天。整个冬季基本断水,5度以下就要开始慢慢断水了。 当夏季温度超过35℃时,整个植株生长基本停滞。这个时候应减少浇水,防止因盆土过度潮湿引起根部腐烂。并加强通风,适当遮荫,避免烈日曝晒,整个夏季基本这样养护,值得说明的是夏季,并非整个季节都断水,是只给微量的水,不然老叶容易干枯,浇水在盆的边上,一个月大概2次,在晚上7-9点左右给水,这个时候太阳已经下山去了,不会对植物的根部造成影响。栽培中要避免长期雨淋,不然会腐烂。 月兔耳因为长的相对较快,1~2年换盆一次就差不多了,初春头次浇水前进行换盆。月兔耳株形不会太小,有分枝,繁殖可以砍头扦插和分株。枝条扦插很简单,把健康的老枝条取下晾干扦插在微微湿润的沙土就可以。阴凉通风20天以上基本会长根,扦插是不要经常给水,不然也容易烂茎,扦插应该选择春季和秋季。 [图片]病虫害防治 病虫害少见,为避免病害,栽培土应用新鲜土壤。 有萎蔫病和叶斑病危害,用50%克菌丹800倍液喷洒。虫害有介壳虫和粉虱危害,可用40%氧化乐果乳油1000倍液喷杀。

Tulips (Tulipa) form a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs). The flowers are usually large, showy and brightly colored, generally red, pink, yellow, or white (usually in warm colors). They often have a different colored blotch at the base of the tepals (petals and sepals, collectively), internally. Because of a degree of variability within the populations, and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to Amana, Erythronium and Gagea in the tribe Lilieae. There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble. Tulips originally were found in a band stretching from Southern Europe to Central Asia, but since the seventeenth century have become widely naturalised and cultivated (see map). In their natural state they are adapted to steppes and mountainous areas with temperate climates. Flowering in the spring, they become dormant in the summer once the flowers and leaves die back, emerging above ground as a shoot from the underground bulb in early spring. [图片]While tulips had probably been cultivated in Persia from the tenth century, they did not come to the attention of the West until the sixteenth century, when Western diplomats to the Ottoman court observed and reported on them. They were rapidly introduced into Europe and became a frenzied commodity during Tulip mania. Tulips were frequently depicted in Dutch Golden Age paintings, and have become associated with the Netherlands, the major producer for world markets, ever since. In the seventeenth century Netherlands, during the time of the Tulip mania, an infection of tulip bulbs by the tulip breaking virus created variegated patterns in the tulip flowers that were much admired and valued. While truly broken tulips do not exist anymore, the closest available specimens today are part of the group known as the Rembrandts – so named because Rembrandt painted some of the most admired breaks of his time. Breeding programs have produced thousands of hybrid and cultivars in addition to the original species (known in horticulture as botanical tulips). They are popular throughout the world, both as ornamental garden plants and as cut flowers. [图片]Tulips are mainly distributed along a band corresponding to Latitude 40o north, from south-east of Europe (Ukraine, Russia) and Turkey in the west, through the Levant (Syria, Israel, Palestinian Territories, Lebanon and Jordan) and the Sinai Peninsula. From there it extends eastwards through Jerevan, (Armenia) and Baku (Azerbaijan) and on the eastern shore of the Caspian Sea through Turkmenistan, Bukhara, Samarkand and Tashkent (Uzbekistan), to the eastern end of the range in the Pamir-Alai and Tien-Shan mountains in Central Asia, which form the centre of diversity. Further to the east, Tulipa is found in the western Himalayas, southern Siberia, Inner Mongolia, and as far as the northwest of China. While authorities have stated that no tulips west of the Balkans are native, subsequent identification of Tulipa sylvestris subsp. australis as a native of the Iberian peninsula and adjacent North Africa shows that this may be a simplification. In addition to these regions in the west tulips have been identified in Greece, Cyprus and the Balkans. In the south, Iran marks its furthest extent, while the northern limit is the Ukraine. Although tulips are also throughout most of the Mediterranean and Europe, these regions do not form part of the natural distribution. Tulips were brought to Europe by travellers and merchants from Anatolia and Central Asia for cultivation, from where they escaped and naturalised (see map). For instance, less than half of those species found in Turkey are actually native. These have been referred to as neo-tulipae. Tulips are indigenous to mountainous areas with temperate climates, where they are a common element of steppe and winter-rain Mediterranean vegetation. They thrive in climates with long, cool springs and dry summers. Tulips are most commonly found in meadows, steppes and chaparral, but also introduced in fields, orchards, roadsides and abandoned gardens. [图片]
