核桃枝接新方法——双嵌接和嵌腹接

New Branch Grafting Methods of Juglans Regia:Double Embedding Grafting and Embedding Abdomen Grafting

为了提高核桃嫁接的成活率,根据前人研究的结果和核桃易剥皮的特点,探索出"双嵌接"和"嵌腹接"两种核桃枝接新方法。与传统的切接法相比,采用双嵌接法于春季对核桃进行枝接,砧穗接触面增加了1倍,有着较高的嫁接成活率和优良的苗木愈合质量;在借鉴并改进油茶"嵌合技接"法的基础上,采用嵌腹接法于夏、秋季对核桃进行枝接,其砧穗接触面积比"嵌合枝接"的有较大幅度的提高,与核桃方块形芽接法相比,其对接穗质量的要求降低了而利用率却提高了,且枝接效果显著。

In order to improve the survival of walnut grafting, two new methods were proposed according to the results of previous studies and characteristics of easy peeling： double embedding grafting and embedding abdomen grafting. Double embedding grafting doubled touch area of buds and seedlings than traditional cutting grafting. When double embedding grafting was used in spring branch of Juglans regia, grafting plants had high survival rate and good concrescence quality. Embedding abdomen grafting improved branch grafting of Camellia oleifera. It largely increased touch area of buds and seedlings than embedding branch grafting, and reduced the requirement of seedlings quality and enhanced the utilization rate than square bud grafting of Juglans regia. When used in branch grafting of Juglans regia in summer and autumn, we got good effect.
