果树苗发展迅速,果树苗的利润略有下降,种植绿化苗木的利润空间较大,城市发展和新农村的建设,对绿化苗木的需求日益加大,经济效益相当好。 Seedling cultivation method to improve the survival rate. Fruit development is rapid, profit fell slightly fruit tree seedlings, planting green nursery stock profit space is larger, the urban development and the construction of new countryside, increasing demand for green seedlings, economic benefit is quite good. 一、树苗种植第一步,种植前,要挖好树穴,树穴大小、深度合理 Before the first step, tree planting, planting, to dig good net-poles, net-poles size, depth, and 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。 According to the different seedling planting depth is also different, such as: cedar, magnolia, meadow, ginkgo, etc. Should be a little shallow. The main reason is shallow root system or not to water wet, permeability is poor soil need more attention. 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. The tree deep root system, generally happy event is wet, large quantities of water transpiration, timely around good tree weir, doused with fixed root water as soon as possible, winding straw rope moisture in time. 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 saplings grow the second step, anti-season humidifying trunk and leaves in the morning and evening, 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。 According to the tree and the tree to support. Especially big canopy of trees, such as: cedar, magnolia, full crown big leaf privet ball. 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。 2, 3 m above the cedar use 4 root bamboo pole diagonal bracing, other practices. Bamboo pole ground 50-60 cm pile end nails, wire strapping fixed. 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.
