一、砧木苗的培育1.堆土分株法:一般用草樱桃(中国樱桃)的萌蘖堆土分株。草樱桃丛生的枝干易生不定根,并有很强的萌发根的能力,在其基部培土堆促使生根。第二年春天进行分株移植。2.扦插法:冬季修剪时在实生树幼树上剪取一年生枝条做接穗,插穗长18cm 左右,每50—100枝一捆,用细沙冬藏,第二年春分前在整好的苗圃地内,做畦开沟插。每亩可插24000条接穗。插后加强肥水管理促使旺长,6—7月份砧木苗长达20cm 高时,可进行多次摘心,使其加粗,8—9月份即可进行嫁接,此种方法育苗速度快,两年内一亩苗圃地可育苗16000—19000棵,在土肥、排水良好、大面积栽植地区,适宜用此法育苗。3.樱桃埋干繁殖法:育苗地翻耕施肥后,按50厘米行距开10—15厘米深的沟,将已育成的樱桃苗木顺沟斜栽,株距大致和苗高相等,栽后踏实根部土壤,再把苗木顺沟向压倒固定,上履1— First, the cultivation of rootstock seedlings 1. Soil stubble method: General grass cherry (China cherry) sprout stubble soil ramets. The grassy cherry branches are prone to adventitious roots and have a strong germinating ability to root and facilitate rooting at their base. The next spring ramets transplantation. 2. Cuttings: winter pruning tree seedlings in the annual tree cut an annual shoots scion, cuttings about 18cm long, every 50-100 sticks, sand with small sand winter possession, the second year before the spring equinox nursery In the ground, do 畦 open ditch insert. Can be inserted per acre 24,000 scion. After plug fertilizer and water management to promote prosperity, from June to July when the rootstock seedlings up to 20cm high, you can make many topping, make it bold, 8-9 months can be grafted, this method seedling speed, within two years An acre of nursery seedlings can grow 16000-19000 trees, in soil fertility, good drainage, large-scale planting areas, suitable for this method nursery. 3. Cherry buried propagation method: Nursery to tillage and fertilization, according to 50 cm line spacing 10-15 cm away from the ditch, will have been bred cherry seedlings along ditch oblique planting, plant spacing roughly equal to the height of the seedlings, planting roots after the implementation of solid Soil, then the seedlings along the ditch overwhelmed fixed on the 1-
