3～4月以后令箭荷花隨著氣溫的升高而生長加速，此時，應將其放向陽窗臺通風處，澆水不宜多，以見干見濕，保持盆土略濕潤為度。每2周施兩次氮、磷結合的液肥，連續(xù)施2～3次。
在園林施工和別墅環(huán)境綠化時，栽植水生植物有兩種不同的技術途徑：一是在池底砌筑栽植槽，鋪上至少15厘米厚的培養(yǎng)土，將水生植物植入土中；二是將水生植物種在容器中，再將容器沉入水中。但是兩種方法各有利弊。一般第二種方法比較常用一些，因為實用第二種方法是它移動方便，例如北方冬季須把容器取出來收藏以防嚴寒；在春季換土、加肥、分株的時候，作業(yè)也比較靈活省工。同時，這種方法能保持池水的清澈，清理池底和換水也較方便。
根通常不生于泥土內(nèi)而伸展于水中，植株浮于水面或隨水流、風浪飄動。如浮萍、水浮蓮（大薸）、水葫蘆（鳳眼蓮）等。水生植物另一個突出特點是具有很發(fā)達的通氣組織，蓮藕是最典型的例子，它的葉柄和藕中有很多孔眼，這就是通氣道?？籽叟c孔眼相連，彼此貫穿形成為一個輸送氣體的通道網(wǎng)。這樣，即使長在不含氧氣或氧氣缺乏的污泥中，仍可以生存下來。通氣組織還可以增加浮力，維持身體平衡，這對水生植物也非常有利。水是生命的搖籃。在水生環(huán)境中還有種類眾多的藻類及各種水草，它們是牲畜的飼料、魚類的食料或魚類繁殖的場所。 2、灌水：繼續(xù)對養(yǎng)護綠地進行及時的澆水。
3、施肥：對草坪、灌木結合灌水，追施速效氮肥，或者根據(jù)需要進行葉面噴施。
4、修剪：剪除冬、春季干枯的枝條，可以修剪常綠綠籬。
5、防治病蟲害：（1）蚧殼蟲在第二次蛻皮后陸續(xù)轉移到樹皮裂縫內(nèi)、樹洞、樹干基部、墻角等處分泌白色蠟質(zhì)薄繭化蛹?？梢杂糜仓駫咧銙叱?，然后集中深埋或浸泡?；蛘卟捎脟姙⒚傻绒r(nóng)藥的方法。（2）天牛開始活動了，可以采用嫁接刀或自制鋼絲挑除幼蟲，但是傷口要做到越小越好。（3）其它病蟲害的防治工作。
6、綠地內(nèi)養(yǎng)護：注意大型綠地內(nèi)的雜草及攀援植物的挑除。對草坪也要進行挑草及切邊工作。
7、草花：迎五一替換冬季草花，注意做好澆水工作。
8、其它：做好綠化護欄油漆、清洗、維修等工作。 深圳沃水從事水生植物培育種植與水生態(tài)環(huán)境修復建設的綜合服務商，是國家級首批高新技術企業(yè)，公司是國內(nèi)最早研究水植物種植培育的企業(yè)之一，主營業(yè)務為：水生植物銷售，水生植物批發(fā)，水生植物基地，水生植物苗場。

Every year before and after the vernal equinox, we combine the ramets and change the soil to keep the soil fertile, so as to meet the demand for the new year's nutrient in Huizhou.
Two, expand the water surface: the water surface is small, the leaf overlap, will affect the flowering, the best pot cultivation, and pot culture to provide more water to provide more water to promote its good growth and blossom.
Three, add fertilizer: potted lotus leaf fertilizer, usually as long as the choice of fertile soil, planting lotus seeds when adding chicken dung and bone meal as base fertilizer is enough. If we want to encourage more flowering, we can add several phosphorus and potassium topdressing in the flowering stage. No more nitrogen fertilizer should be applied. Otherwise, too much vegetative growth will inhibit its reproductive growth, resulting in poor flowering or no flowering.
Four, pest control: the leaves of the water lily are easily encroach on the leaf pests such as the burglar moth, causing the leaf surface damage and reducing the photosynthesis, which is bound to affect the flowering and should be prevented and controlled in time.
After 3~4 months, the arrow lotus flower grows with the increase of temperature. At this time, it should be put into the ventilating place of the b table. It is not suitable to water more, in order to see dry wet, and keep the basin soil slightly moist. Two nitrogen and phosphorus combined liquid fertilizers were applied every 2 weeks for 2~3 consecutive times.
In the garden construction and the villa environment greening, there are two different technical ways to plant the aquatic plants. One is to build planting grooves at the bottom of the pool, spread the cultivated soil at least 15 centimeters thick, and implant the aquatic plants into the soil; the two is to plant the aquatic plants in the container and then sink the container into the water. But the two bs have their own advantages and disadvantages. Generally, the second bs are commonly used, because the second practical bs are convenient to move, for example, in the northern winter, the containers must be collected to prevent the cold. In the spring, the work is more flexible and more flexible when changing soil, adding fertilizer and ramets. At the same time, this b can keep the pool water b, and clean the bottom of the pool and change the water.
Roots are usually not born in soil and extend in water. Plants float on the surface of the water or float with the currents and waves. Such as duckweed, hyacinth (Hyacinth), water hyacinth (Feng Yanlian) and so on. Another prominent feature of aquatic plants is the well-developed aeration tissue, the lotus root is the most typical example, its petiole and lotus root have many holes, this is the ventilation. The hole is connected to the hole and penetrates each other to b a channel network for conveying gas. In this way, even in the sludge without oxygen or oxygen deficiency, it can still survive. Ventilating tissue can also increase buoyancy and maintain body balance, which is also very beneficial for aquatic plants. Water is the cradle of life. There are many kinds of algae and aquatic plants in aquatic environment. They are feed for livestock, food for fish and breeding place for fish. 2, irrigation: continue to maintain green space timely watering.
3, fertilization: combine turf and shrub irrigation, apply quick acting nitrogen fertilizer, or spray foliage according to need.
4, prune: cut off dry branches in winter and spring, and trim evergreen hedge.
5, the prevention and treatment of pests and diseases: (1) the scale shell insect transferred to the bark crack, the tree hole, the trunk of tree trunk, the corner of the wall and so on after the second molting. It can be removed with hard bamboo broom, and then concentrated or buried deep. Or the b of spraying insecticide and other pesticides. (2) the beetles began to move. They could use grafting knives or self-made steel wires to remove larvae, but the smaller the wound, the better. (3) prevention and control of other diseases and pests.
6. Conservation in the green space: notice the weeds in large green spaces and the removal of climbing plants. It is also necessary to pick grass and cut the edge of the lawn.
7, grass flower: let's replace the winter flower in Wuyi, and do a good job of watering.
8, others: do green fence painting, cleaning, maintenance and so on.
