利用对萼猕猴桃砧木建园与栽培管理技术

Orchard establishing and cultivation and management techniques using new rootstocks(A ctinidia valvata Dunn)

以对萼猕猴桃为主的新型砧木具有耐涝、生长势强等特点,逐渐在多雨、土壤黏重地区的猕猴桃新建园中推广使用。主要阐述第1年定植砧木苗(对萼猕猴桃基砧+米良1号中间砧),第2年嫁接品种并做“一干两蔓羽状侧枝”树形培养与整形,实现第3年试挂果并稳固树形的建园与栽培管理技术。

The new rootstocks mainly include ActinidiavalvataDunn have the characteristics of waterlogging tolerance and strong growth potential,and gradually popularized and used in the new kiwifruit garden in rainy and sticky soil areas.In this study,A.valvataDunn and‘Miliang 1’were used as rootstock and interstock,respectively.The intact rootstocks were planted in the first year,and cultivars were grafted in the next year.Tree management methods summarized as“one trunk and two vines following with pinnate lateral branches”were also carried out in the second year.This technology can guarantee a small amount of fruit and stabilize the tree shape in the third year,and lay the foundation for high and stable yields.
