核桃圃地苗木嫁接技术,是核桃良种化的关键。为提出切实可行的嫁接技术,于1983～1985年,对核桃圃地嫁接时期、方法、接穗质量、克服伤流及愈合过程进行了试验观察。试验结果表明:在春季砧木离皮后,采用舌接法嫁接,3年平均成活率达90％以上;砧木不离皮期可应用贴接和劈接法,成活率可达85％。核桃圃地嫁接成活的关键是接穗新鲜,质量好,接穗直径在0.50～1.75cm,砧木无伤流或伤流少。
Walnut nursery seedlings grafting technology, is the key to walnut varieties. In order to put forward the feasible grafting technology, the grafting period, method, scion quality, wound-healing and healing process in walnut nursery were studied from 1983 to 1985. The results showed that the average survival rate of three-year survival rate was more than 90% after the rootstocks were detached from the skin in spring, and the survival rate could reach 85%. Walnut nursery land grafting is the key to fresh scion, good quality, scion diameter of 0.50 ~ 1.75cm, rootstock no wound or injury less.
