| 一、树苗种植第一步，种植前，要挖好树穴，树穴大小、深度合理 One, the tree seedlings grow the first step, before planting, want to dig the hole, the hole size, the depth is reasonable 树穴直径比土球大树干胸径3~4倍距离、树穴深度比土球高度大2倍树干胸径距离，种植前垫起1.5倍树干胸径的深度（用周边风化的土壤埋植，并适当捣实，过实不透气，过松浇水则易倒伏或积水），种植完后土球一般低于地表5厘米，过深易造成根部透气性差，造成苗木窒息死亡。 Net-poles diameter of trunk diameter at breast height 3 ~ 4 times larger than soil ball distance, net-poles depth 2 times larger than soil ball high tree diameter at breast height, distance before planting mat up 1.5 times the depth of the tree diameter at breast height (preparetions with weathering of surrounding soil, and the appropriate tamping, a real airtight, water is too loose easy lodging or water), planting after been ball generally 5 cm below the surface, deep easy to cause the roots of poor permeability, seedling suffocation deaths. 根据苗木种类不同种植深度也有所不同，如：雪松、广玉兰、合欢、银杏等应稍浅。主要原因是浅根系或不耐水湿，透气性差土壤更需注意。 The planting depth varies according to the species of seedlings, such as cedar, magnolia, acacia, ginkgo, etc. The main reason is that the shallow root system or the water is not waterproof, and the permeability of the soil is more important. 而如：龙柏、法桐、柳树等又应适当稍深，对一些规格稍大或特殊苗木种植前对土球或根部进行喷洒、浇灌活力剂或生根剂等辅助措施。该类树种一般深根系，喜水湿，蒸腾水分量大，及时围好树堰，尽快浇上定根水，及时缠绕草绳保湿。 And such as Sabina chinensis, platane, willow and should be a bit deep, appropriate for some little older specifications or special tree planting on soil ball or the roots before spraying, water dynamic agent or rooting agent and other auxiliary measures. This kind of tree species is deep root system, the water is wet, transpiration water is large, the tree weir is enclosed in time, and the water can be doused quickly, and the grass rope can be wrapped in a timely manner. 二、树苗种植第二步，反季节早晚加湿树干及树叶，过热季节做遮阳处理 Second, the seedling grows the second step, the opposite season adds wet tree trunk and leaves, the hot season do shading treatment 种植前根据设计要求及树种作合理修剪，减少树体水分蒸发，截干部位作封口处理，以防坏死、风干、水分流失导致苗木死亡。 Before planting and tree species for reasonable clip according to design requirements, reduce evaporation of trees, cut the sealing treatment of cadres who from gangrene, air drying, water loss led to the deaths of nursery stock. 根据树种及树形及时做好支撑。特别是树冠偏大的树种，如：雪松、广玉兰、全冠大叶女贞球。 The tree is supported by tree species and tree in time. In particular, there are large tree species such as cedar, magnolia, and full crown. |
