摘 要: | 以薄壳核桃1年生大小均匀的实生苗作为砧木,通过移栽、断根和不断根3种处理方式,采用切接法,在不同时间对薄壳山核桃进行嫁接,研究嫁接时间和砧木不同处理方式对嫁接成活率及新梢生长状况的影响。结果表明:4月8号3种砧木处理方式嫁接成活率均出现峰值,其中移栽切接的成活率最高,为86.8%,5月28号到7月28号3种砧木处理方法嫁接成活率基本相同,为33.0%~46.7%。砧木的粗度与新梢的粗生长与高生长之间存在正相关关系。

Abstract: | Choose 1-year-old Carya illinoensis seedling as rootstock and applied cut-grafting method,to study the effects of the grafting time and 3 treatments (transplanting grafts,root pruning cut grafts and not root pruning cut grafts)on survival rate and the growth of shoots.The results showed that:after grafting,the survival rate of 3 treatments appeared a peak at April 8 th .Among of them,the survival rate of transplanting grafts was the highest which was 86.8%.From 28 th May to 28 th July,the survival rate of the three treatments was basically equal (33%-48.6%).The crude and high growth of new branchs was positive correlated to the rootstock’s diameter. |
