核桃 (ＪｕｇｌａｓｒｅｇｉａＬ)是栽培价值很高的干果树种 ,历史上由于实生栽植 ,结实晚 (10年以上 ) ,在很大程度上影响了核桃生产的发展。采用嫁接技术 ,把核桃优良母树的结果枝嫁接在实生苗上 ,可提前到 3～ 5ａ结果。我国科技工作者在长期研究中 ,总结出多种嫁接方法 ,但 Juglasregia L., a cultivated dried fruit tree, has historically been affected by the fact that seedlings are planted live longer (over 10 years) which has a significant impact on the development of walnut production. The use of grafting technology, the good results of walnut grafted tree branches in seedlings, can advance to 3 ~ 5a results. In the long-term research, our country’s science and technology workers summed up a variety of grafting methods, however
