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. Especially the large tree species, such as cedar, wan, and full-crowned female. 

1、3m左右雪松应选用3根4—5m（Φ4—5cm）竹杆支撑，绑扎部位选用无伤布条缠绕三周，选用14号铁丝收紧（铁丝不易过粗，不然收不紧，太细易断）。

1, 3 m or so cedar should choose 3 4, 5 m (Φ 4-5 cm) bamboo poles, binding site choose three weeks without injury ribbons, choose 14 tightening wire (wire not too thick, otherwise close not tight, too thin brittle). 

2、3m以上雪松选用4根竹杆对角支撑，其它做法一致。竹杆地面端钉50—60cm木桩、铁丝捆扎固定。一般树干胸径6—8cm及以上全冠苗木均需作支撑处理，骨架树种酌情处理，截杆树种视胸径大小，一般12cm胸径以上作支撑。特殊高大苗木（Φ20cm以上）需用钢管#字形栓架支撑。

The four bamboo poles are supported by four bamboo poles and the other is the same. The ground head of bamboo pole is fixed with 50 to 60cm wooden pile and iron wire. General trunk diameter at breast height 6 -- 8 cm or more full crown seedling supported all needs to deal with, skeleton tree species act accordingly, cut stem tree diameter at breast height size, generally more than 12 cm diameter at breast height as support. Special tall seedlings (20 cm) above Φ need steel tube # glyph bolt support. 

三、树苗种植第三步，浇水

Third, plant the third step, water 

一般苗木种植后最关键为前三遍水，一定要浇透座根密实利于生根。根据耐水湿性又不可间隔时间短，以免影响根部呼吸及积水烂根，所以也需考虑土壤特征、性质。一般情况下头三遍水一周至10天完成，见干则浇透，不干不浇，浇则浇透，浇透后1—2天后及时培土保墒，条件允许根部埋设透气管孔。起苗到种植完成一般不超过24小时，特殊季节更要缩短，所以要做到提前计划统筹。尽量先挖好坑后到苗及时种植，特殊土壤如盐碱地作防碱处理。坚土、粘土提前树穴灌水加湿等。

The key to the first three times when planting the seedlings is to water the roots. It is also necessary to consider soil characteristics and properties according to the fact that the water is not too wet and the time is too short to affect the root breathing and water. Generally water head three times a week to 10 days to complete, see dry drenched, not stem not watering, watering is drenched, drenched in 1-2 days after timely ridging keep moisture, conditions allow the roots buried vent pipe holes. When seedlings go to the plant to finish normally not more than 24 hours, the special season is shorter, so plan for the planning in advance. Try to dig the hole first and then plant the seedlings in time. The special soil will be treated as alkali and alkali. The soil, clay, the early tree, the water and the water. 

四、花灌木及模纹种植类苗木种植

4, flower bushes and mold planting seedlings 

花灌木及模纹种植类苗木种植前应提前画好位置、翻地松土，主要是提高种植效率，及加快生根。根据设计要求及苗木种类及时修剪减少水分蒸发，提高成活，及时浇水，有条件的要作遮阳，防风处理。

The planting of shrubs and moulded plants should be done before planting, which should be done in advance, which will improve the efficiency of planting and accelerate the development of the plant. According to the design requirement and the seedling type in time to reduce the moisture evaporation, improve the life, the timely water, the condition is to be shading, the windproof treatment. 

气温零下后一般苗木均不太宜种植，容易造成根部冻伤，导致死亡。有些苗木过冬前要做好防冻措施，并尽量提前做，有些树种作树冠防冻，有些需作根部覆盖地膜防冻处理，材料选择内草席外薄膜。上下封闭捆扎，大规格苗木作单体保湿房。需作防冻处理苗没有栾树（下半年种植，防冻时间1年)、广玉兰（2—3年）、海桐（2年）、火棘（2年）、石楠（1—2年）、桂花（每年）等。

When the temperature is below zero, it is not suitable for planting, which can cause the root to freeze and cause death. Some seedling before winter antifreeze measures is to work and try to do ahead of time, there are some tree species for canopy antifreeze, some should be base film winterization, membrane material selection within the mat. The upper and lower sealing bundles are made up of a large scale of seedlings. To make antifreeze processing plants without goldenrain tree (in the second half of the planting, anti-freezing time 1 year), magnolia (2 to 3 years), pittosporum (2 years), fire spines (2 years), heather (1-2 years), osmanthus (per year), etc.
