核桃室外枝接新技术研究

对目前广泛应用的3种核桃室外嫁接技术进行了应用评价;在理解嫁接概念的基础上发明了核桃嵌合接、核桃双嵌接两种枝接新方法,其砧穗接触面积、嫁接成活率、苗木质量等技术指标均较传统枝接方法有很大幅度的提高;总结出砧穗质量、伤流控制、愈合条件是除枝接方法之外影响核桃室外枝接成活的关键因素,研究出能综合解决这三大关键因素的3套技术方案.

A Study about the Outdoor Walnut-grafting Technology

The thesis is a conclusion about the outdoor walnut-grafting,which the writers have been practising for recent ten years.It is the applied evaluation about three walnut grafting technologies,used widely in present.After understanding the concept of walnut grafting,we have carried out two new technologies,the insert-planting and diploid-insert-planting,which improve more largely on the contacting area of spiking the stock,the proportion of grafting surviving and the quality of seedling and so on than traditional ways.Furthly,we come to a conclusion that apart from the way of the walnut-grafting,three elements,quality of spiking the stock,controlling the hurt and conditions of healing,are the key to the survival of outdoor grafted walnuts,and we work out three series of technology scheme,which can generally solve the above three questions.
