春季气温回升，天气转暖，是进行绿化、种植苗木的最佳时机。为取得较好的绿化效果，最大程度提高苗木成活率，在苗木种植过程中，需要注意以下几点：

The rise of temperature in spring, the weather gets warmer, is the best time for afforestation, planting seedlings. To achieve good greening effects, enhance the survival rate of nursery stock, to the greatest extent in the process of tree planting, need to pay attention to the following: 

一、种植施工现场准备。种植苗木前要先平整施工现场土地，按照设计方案定点放线，挖种植穴。种植穴的大小应根据树苗的大小和土壤土质的不同来决定，施工现场如土质不好，应换入无杂质的砂质壤土，以利于根系的生长。种植穴可施底肥，然后再覆素土，不要使树根直接与肥料接触，以免烧伤树根。

A, planting construction site preparation. Before planting seedling flat land on the construction site, according to the design of fixed-point pay-off, digging the hole. The size of the hole should be according to the size of the tree and the soil of different soil to decide, if the soil is bad on the construction site, should be in sandy loam without impurities, to facilitate the growth of root system. The hole can be recommended, then cover soil, do not make direct contact with the fertilizer of roots, so as not to burn the roots. 

二、苗木选择。尽可能挑选长势旺盛、植株健壮、根系发达、无病虫害、容易成活的苗木，慎重选择南方苗木，不要选择成活率低的苗木。

Second, the nursery stock options. As far as possible choose growing strong, robust, root developed, no plant diseases and insect pests, easy to survival of seedlings, carefully choose the south nursery stock, don't choose the low survival rate of seedlings. 

三、起苗、运苗。起苗是种植树木的第一步，应尽可能挖得深一些，注意保护根系少受损伤。一般常绿树起苗时要带好土球，以防泥土松散。落叶树起苗时可裸根，胸径15公分以上的要带土球。树苗挖好后，要遵循随挖、随运、随种的原则，及时运出种好。在运苗之前，为避免树苗枯干，应进行包装，用草绳、麻布或草包将土球、树干、树枝包好，喷水保持湿润，减少运输途中苗木的蒸腾量。

Three, miao, miao. Miao is the first step to plant trees, should dig deep as far as possible, pay attention to protect root less damage. Should take soil ball when built general evergreen plants, to prevent the soil loose. When deciduous tree seedlings can be bare root, diameter at breast height more than 15 cm ball to zone. Seedlings after digging well, to follow along with the dig, with luck, as a principle, timely out of the good. Before shipment seedlings, to avoid saplings wither, should carry on the packing, the rope, linen or straw bag will soil ball, trunk, branches, water moist, reduce transpiration of nursery stock in transit. 

四、种植前修剪。种植前要对苗木根系和树冠进行适当修剪，以减少水分的散发，保持苗木地上、地下部分生长平衡和树势平衡，保证树木成活。一是根系修剪。将断根、劈裂根、病虫根和过长的根剪去，剪口要平滑，并喷施防腐剂和生根剂。二是树冠修剪。应适当轻剪，去除病虫枝、枯死枝、生长衰弱枝、过密枝和下垂枝，保留主分枝，在保证树形情况下，可剪去一部分幼嫩枝叶，并抹掉分枝点以下的芽，减少树体水分消耗。灌木根部萌发的蘖枝要齐根剪掉，避免水分流失。苗木修剪直径大于2厘米的枝条要涂抹防腐剂或油漆等。

Four, trimmed before planting. Before planting seedling root and crown to be properly clip, in order to reduce water loss, balance of seedling growth on the ground and underground part and tree potential balance, trees survival guarantee. One is the root pruning. Will be increased, splitting the root, the root of diseases and pests and long root, cut out cut mouth should be smooth, and spraying preservatives and rooting agent. The other is the crown of a tree pruning. Should be appropriate light, get rid of diseases and pests, dead branches, and growth weakness, drooping branches and twigs, retain the main branch, under the condition of ensure the tree, can cut off part of the tender branches and leaves, and erase bud under the branch point, reduce the water consumption of trees. Shrubs order tiller JiGen to cut off the root germination, avoid moisture loss. Seedling pruning the branches of the larger than 2 cm in diameter to daub preservatives or paint, etc.
