[图片]发芽种植法 第一种方法是栽种发芽的洋葱。首先取几个个已经发芽了的洋葱，然后要将外面的一层薄皮去掉，但是一定不要伤害到洋葱下面的根须。下一步就要把洋葱小心的切开，不能切到或是伤害中间的发芽处。然后可以把剩下的洋葱除掉了，将中间发芽处留下备用，注意去掉的部分不要浪费可以吃哦。选择合适的花盆以及基质，将洋葱的根部乡下栽种进土壤中，要适当的浇水，保证光照，注意通风，慢慢地等待，就可以看到洋葱发芽成长了。 [图片]生根种植法 这种方法适合想要吃洋葱叶的朋友，具体方法如下。选择一个五升的矿泉水瓶备用，准备好土壤和洋葱就可以开始了。先要把瓶子洗干净，让后剪掉瓶颈，并需要在瓶身周围剪开很多比洋葱的直径要小一点的小圆孔。将土壤放进去，在圆孔的位置种上洋葱。要定时浇水，使土壤保持潮湿就可以了，把矿泉水瓶放到窗台上，保证光照，静静观察，过一段时间就会发现洋葱长出叶子了。如果要用葱花的话，可以用洋葱叶代替哦，味道差不多。 [图片]

Scientific Name Euphorbia obesa Hook. [图片]Common Names Basketball, Sea Urchin, Baseball, Living Baseball, Baseball Plant, Gingham, Golf Ball, Vetmensie, Klipnoors Scientific Classification Family: Euphorbiaceae Subfamily: Euphorbioideae Tribe: Euphorbieae Subtribe: Euphorbiinae Genus: Euphorbia [图片]Flower Color: Green Bloom Time: Mid summer Description Euphorbia obesa is a spineless, grey-green, dwarf, spherical succulent plant with transverse red-brown or purplish bands. It can grow up to 7.8 inches (20 cm) tall and up to 3.5 inches (9 cm) in diameter. Rudimentary, caducous leaves. Usually 8, vertical, broad, slightly raised ribs with shallow furrows in between. Small inflorescence borne on short peduncle from stem apices. Female and male flower are born on different plants. The fruit is a slightly three angled capsule, up to 0.3 inch (7 mm) in diameter. [图片]How to Grow and Care Euphorbias are very easy to care for. They require a little pampering to become established, but once they are, they are self-sufficient. In fact, more die from too much care and watering than from neglect. Euphorbias need well-draining soil and lots of sunlight. They are not particular about soil pH, but they cannot tolerant wet soil. Unlike most succulents, Euphorbia does not handle long periods of drought well. It may need weekly watering during the summer. Water whenever the soil is dry several inches below the surface. Water deeply, but don’t let them sit in wet soil, which can cause root rot. Add some organic matter or fertilizer to the planting hole. If you are growing them in containers or your soil is poor, feed with a half-strength fertilizer monthly. Origin Native to South Africa, especially in the Cape Province.

[图片]一、虫害： 说道叶子发黄，相信很多人和小编一样认为是害虫所致。这时我们要先检查下洋桔梗植株上有没有虫子。如果有，那么就“对症下药”，选择相应的药物处理；如果植株上没有发现害虫，也可能是地下病虫搞的鬼。对于这种情况，大面积种植的朋友可以在浇水之前在地里撒一些沙子药。如果家里盆数较少，也可以换一盆新的土，试一试哦。 [图片]二、缺水： 洋桔梗的生长对土壤的水分要求比较高，太干或者太湿均不行。有的朋友在浇水时只做“表面功夫”，即只淋湿土壤表面，而并没有完全浸润土壤。这种情况也可能导致洋桔梗叶子发黄。 三、温差： 如果您的洋桔梗此前是在温室里种植的，那么不用担心，叶子发黄只是由于它需要适应一下温差，过一段时间就恢复正常了。 [图片]四、缺肥： 洋桔梗叶子发黄还可能是肥料不足引起的。肥料充足的情况下，洋桔梗叶子的尖端是向上翘的，看起来也比较挺拔，很有长势。而缺少肥料，则会导致植株没有精神。因此，在施肥前一定要保证土壤湿润，土太干的话会影响肥料的释放。 在这里给大家一个小贴士：一般家庭里种洋桔梗，会选择泥炭，可是泥炭种植很容易导致洋桔梗缺钙。如果不想购买含钙肥料的话，把鸡蛋壳洗净、晾干并压碎后撒在土壤里也能起到肥料的效果。

[图片]猝倒病 这种病通常发生在茄子的苗期，，表现为幼苗靠近土壤的基部有水渍状个，之后会萎缩成为线状，叶子还没落苗已经倒在地表了。为防止这种病的发生，我们要给植物多通风，保持适度的光照，避免过多浇水。也可以使用58%的瑞霉素800到100倍液或是72.2%的普力克600倍液进行防治。 褐纹病 这种病也是茄子的一种常发病，表现为叶子上的病斑从一开始的水渍状变为褐色的轮纹，边缘上会有灰白色和小黑点。果实也会产生病斑并且慢慢的发展成酱色。对于这种情况，我们尽量选择抵抗力好的品种，做好通风工作，还需要适当的降低土壤的湿度。可以用扑海因1500倍液或是50%的菌多灵600倍液进行防治。 [图片]绵疫病 这种病变现为果实上会出现一些水渍状的圆形斑，之后会变成褐色并且凹陷，偶尔还会有密生的白霉出现，最后导致果实腐烂甚至脱落。为此我们在它们成长的时间段内，要勤修整，保证光和空气的流动。也可以配合专门的药物喷洒治疗，会有很好的效果。 [图片]蚜虫 虫害主要有蚜虫，可以用配合专门的药剂直接喷洒治疗。而且还有螨类，它们的危害也比较大，如果发生的花可以用克螨特的1500倍液来防治。

[图片]掉叶子的原因 一般来讲，植物掉叶子不是一件特别稀奇的事情，但是我们需要想清楚的是，琴叶榕掉叶子就不一样了，秦叶蓉可是一种一年四季常绿的植物，有没有繁茂的花朵，没有叶片，那岂不是相当于主治大夫没有手术刀么，想想都觉得有那么一点可怕呢，琴叶榕掉叶子的原因无疑就是阴阳供给不足，土壤中的养分太少，另外，供水不足或者供水过多都会造成琴叶榕掉叶子，养分不足对和供水不足对琴叶榕掉叶子的影响是一样的，就是使叶片枯黄，而供水过多就会使叶片看起来还是绿油油的，但是一碰就容易掉落。 [图片]掉叶子的危害 琴叶榕掉叶子就相当于琴叶榕的死亡，琴叶榕的价值就在于琴叶榕是一种常绿，叶片翠绿可以吸附空气中的杂质分子的植物，一旦叶片开始脱落，不仅没有之前那个样子外观的美丽，而且，也不会再有很强的吸附的能力，这对于琴叶榕来讲无疑是一种死亡。 掉叶子时该怎么办 首先，当发现琴叶榕掉叶子时我们要找到琴叶榕掉叶子的原因，究竟是因为少肥料还是因为缺水还是因为水分供给太多。一般来讲，只要找到原因，问题就很容易解决，如果是少肥料的话，建议给植物施肥，每隔一到两个周施肥一次即可，如果是因为水分的问题，那么建议一周浇水一次，不要浇水过多，一次的水量以正好是土壤完全湿润为宜。 [图片]

#龟背竹 又名蓬莱蕉，主要生长在热带雨林。在我国多地都有栽培，根据龟背竹的生长习性也可以用盆栽来养殖龟背竹，龟背竹不仅具有风水作用，还可以用作家居装饰。那么龟背竹常见的病虫害都有哪些呢？如何才能做到防治龟背竹病虫害呢？ [图片]1.灰斑病 （1）症状特征：该病主要发生于叶片上。开始多从叶缘伤口入侵。病斑为黑褐色，扩大后呈椭圆形至不规则形，斑内为灰褐色，边缘黑褐色。后期病斑连成一片，腐烂干枯。上面产生出稀疏的黑色粒状物，即是病原菌分生孢子器。 （2）防治方法：及时摘除病叶并烧毁。并防虫养护。发病期，喷施70％甲基托布津1000倍液或50％多菌灵1000倍液。 2.锈病 （1）症状特征：初叶片两面现针尖大小黄色小点，后逐渐扩展为浅褐色至砖红色疱斑，圆形、近圆形，后期疱斑开裂散出锈色粉末。严重的锈斑布满叶面，致叶局部或整叶变黄，以致枯黄脱落，使植株长势减弱。茎部也会染病，产生类似于叶片的症状。此病多发生于南方，随苗木调动向北方地区传播。病原菌以夏孢子和冬孢子两种形式越冬。借气流以夏孢子反复侵染。植株摆放过密、湿度大时，发病较重。 （2）防治方法：精心养护，及时清除病叶。发病初期，喷施20％三唑酮乳油1500倍液或25％粉锈宁可湿性粉剂1500倍液、40％新星乳油6000倍液、25％敌力脱乳油3000倍液，连喷3～4次。 [图片]3.柑橘粉蚧 （1）为害特征：为害多种花卉。成虫和若虫吸食枝叶汁液，使植株生长缓慢，枝叶变形皱缩，并诱发煤污病。严重影响观赏效果。 （2）防治方法：虫量少时，及时刮除。花田栽植密度不要过大，确保通风透光。虫量发生严重时，在若虫孵化期，喷施50％杀螟松1500倍液或用50％辛硫磷1000倍液，每10天1次，连喷施2～3次。 4.介壳虫 为龟背竹常见害虫。主要为害叶柄、叶片。 防治方法： （1）家庭养护时可用牙刷将其轻轻刷除。 （2）发生量大时，在若虫期可用40%氧化乐果乳油剂1 000倍液喷洒。

Scientific Name Etlingera elatior (Jack) R.M.Sm. [图片]Common Names Torch Ginger, Ginger Flower, Philippine Wax Flower, Red Ginger Lily, Torch Lily, Wild Ginger, Indonesian Tall Ginger, Porcelain Rose Synonyms Achasma yunnanensis, Alpinia acrostachya, Alpinia diracodes, Alpinia elatior, Alpinia javanica, Alpinia magnifica, Alpinia speciosa, Amomum magnificum, Amomum tridentatum, Bojeria magnifica, Cardamomum magnificum, Cardamomum speciosum, Cardamomum tridentatum, Diracodes javanica, Elettaria speciosa, Geanthus speciosus, Hornstedtia imperialis, Nicolaia imperialis, Nicolaia intermedia, Nicolaia magnifica, Nicolaia speciosa, Phaeomeria imperialis, Phaeomeria magnifica, Phaeomeria speciosa Scientific Classification Family: Zingiberaceae Genus: Etlingera [图片]Flower Color: Red Bloom Time: Throughout the year Description Etlingera elatior is a tropical, rhizomatous perennial that grows up to 15 feet (4.5 m) tall in tropical climates but much shorter in cooler climates. Arching leafstalks up to 15 feet (4.5 m) tall are clad with ribbed, leathery, banana-like leaves (up to 3 feet/90 cm long), each having a central groove. Naked flower stalks rise directly from the rhizomes up to 3 feet (90 cm) tall, each stalk being topped by a cone-shaped inflorescence containing tiny yellow flowers over tiny fertile bracts, both of which are somewhat hidden inside of and subtended by large, drooping, showy petal-like red bracts. Flowers bloom throughout the year. [图片]How to Grow and Care Growing Torch Ginger is possible in a range of soil types. A major problem when growing Torch Ginger plants is potassium deficiency. Potassium is necessary for the correct uptake of water, which is necessary for the optimum growth of this large plant. Add potassium to the soil before growing Torch Gingers by working it into unplanted beds to about a foot (30 cm) deep. Organic means of adding potassium include the use of greensand, kelp or granite meal. Test the soil. When growing these plants in established beds, fertilize with a food that is high in potassium. This is the third number on the fertilizer ratio displayed on the packaging. Once the potassium is right in the soil, watering, an important part of learning how to grow torch ginger successfully, will be more beneficial. Origin Native to Malayasia and Indonesia.
