How to Improve the Survival Rate of Greening Seedlings
一、种植第一步，挖树穴，一定要深度合理
1. The first step in planting trees and digging holes must be in a reasonable depth.
树穴的直径一般需比土球大树干胸径3~4倍距离、树穴的深度也比土球高度大2倍树干胸径距离，种植之前首先垫起1.5倍树干胸径的深度（可以选择用周边风化的土壤埋植，并适当捣实，如果太过严实就会产生不透气的现象，如果土壤过松浇水的话就容易易倒伏或积水），土球需要低于地表5厘米，太深的会使得根部透气性差，苗木也容易窒息而亡。
The diameter of tree holes is generally 3-4 times larger than the diameter of earth-ball trunk, and the depth of tree holes is 2 times larger than the height of earth-ball trunk. Before planting, the depth of tree trunk DBH should be 1.5 times higher than that of earth-ball trunk.zhidaiji.jk56.org   yinshuajii.jk56.org    yinshuaji.jk56.org  guanjianc.jk56.org    guanjiann.jk56.org    guanjianx.jk56.org
(You can choose to bury the surrounding weathered soil and tamp it properly. If the soil is too tight, it will be impermeable. If the soil is watered too loosely, it will be easy to lodge or accumulate water. The earth balls need to be 5 centimeters below the surface. Too deep will make the roots less permeable and the seedlings suffocate easily.
苗木的不同种类决定了其种植深度也需要不一样，如：银杏、广玉兰、合欢、雪松、等应种植的深度应当稍微浅一些。因为浅根系的不耐水湿，如果土壤透气性差土壤那就需要特别留意了。
The different types of seedlings determine that their planting depth also needs to be different, such as: Ginkgo biloba, Magnolia grandiflora, Albizzia, Cedar, etc. should be planted in a slightly shallow depth. Because shallow roots are not water and humidity tolerant, soil with poor air permeability needs special attention.
但是如果是柳树、龙柏、法桐则需要深度稍微深点，低于规格稍微大点的或者是特殊的苗木，在种植之前需要对土球或根部进行喷洒、然后浇上活力剂或生根剂来帮助生长。这种类型的树种一般属于深根系，喜欢水湿，蒸腾时水分量也很大，及时做好树堰围挡，以最快速度浇上定根水，同时缠绕草绳保湿。
But if it is willow, longbai, and phallot, it needs to be a little deeper, a little larger than the specifications, or a special seedling. Before planting, it needs to spray the earth ball or root, and then spray vigor or rooting agent to help growth. This type of tree species generally belongs to deep roots, like water and humidity, transpiration water content is also very large, timely cofferdam to do a good job, with the fastest rate of watering fixed roots, while winding straw rope moisturizing.
二、早晚对反季节树进行树干及树叶加湿
2. Moisturizing the trunk and leaves of off-season trees in the morning and evening
种植前给树种做好合理的修剪工作，这样可以减少树体水分的蒸发，截干部位作封口处理，防止坏死、风干及水分的流失导致苗木死亡。
Reasonable pruning of tree species before planting can reduce evaporation of water in the tree body and seal the cutting position to prevent necrosis, air drying and water loss leading to seedling death.
支撑需要根据树种及树形来完成。尤其是面对树冠偏大的树种，比如广玉兰、雪松、全冠大叶女贞球。
Support needs to be done according to tree species and tree shape. Especially in the face of trees with larger crowns, such as Magnolia grandiflora, Cedar, Ligustrum lucidum.
1、如果雪松在3米左右的话，支撑的竹竿最好用3根4—5m（Φ4—5cm），用无伤布条缠绕三周进行捆绑，选用14号铁丝收紧（铁丝不易过粗，不然收不紧，太细易断）。
1. If cedar is about 3 meters, it is better to use 3 4-5 meters (4-5 cm) to support the bamboo poles, wrap them with harmless cloth strips for three weeks, and tighten them with No. 14 wire (the wire is not too thick, otherwise it is not tightened, it is too thin and easy to break).
2、雪松如果在3米以上的话，支撑一般选4根竹杆对角支撑。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。
2. If cedar is over 3 meters, four bamboo poles are usually selected for diagonal support. Bamboo pole ground end nail 50 - 60 cm stake, wire binding and fixing. Generally, full-crown seedlings with trunk DBH of 6-8 cm or above need to be supported. Skeleton tree species should be treated as appropriate. Truncated tree species should be supported by DBH of 12 cm or more. Special tall seedlings (above 20cm) need to be supported by steel pipe glyph bolt.
