核桃改良芽接技术成活率研究

Survival Rate of Walnut by Improved Bud Grafting Techniques

通过对核桃传统芽接与改良芽接技术成活率进行比较,以及对核桃改良芽接技术的绑扎方式、割砧方式、嫁接时期的确定和穗条的选择等关键步骤进行统计分析,以期为核桃嫁接提供参考。试验结果表明,采用割砧留放水口、绑扎用薄膜、选择芽饱满且粗壮的大穗条和嫁接选择在6月中下旬等技术改良措施,可有效提高核桃嫁接成活率。

Reference were provided for walnut production by comparing the traditional walnut budding technology to the modified one,and improving the binding methods,anvil cutting methods,grafting period and selection of scions. It was showed that survival rate of walnut could be improved effectively by using film to colligate,choosing full buds and strong scions,and grafting in mid-late June.
