【摘要】 在洛南不同区域、不同时期的试验结果表明 ,限制核桃芽接成活率的主要制约因子包括气温 (嫁接期 )、接前放水、复叶保留和嫁接速度 ;制约因子的有效控制为 :适宜嫁接期为 6月1 0日至 7月 1 0日 ,最佳期为 6月 2 0至 6月 30日 ;气温 2 0 .0～ 2 3.0℃ ,2 2 .0℃～ 2 2 .5℃最佳 ;采取接前 2～ 3d灌水 ,2 d最佳 ;同步进行 2～ 3片复叶保留 ;操作方法正确、熟练 ,在 1 min内完成单株嫁接即可显著提高核桃嫁接苗木的成活率更多还原

【Abstract】 The experiment in different areas and different times in Luonan showed that: the major factors of limiting the walnut budding take included temperature grafting rate and releasing water before grafting retaining compound leaves and grafting rate; the effective control of limitative factors included: proper grafting time during 10/June～10/July, optima during 20/June～30/June; temperature at 20.0～23.0℃, optima at 22.0～22.5℃; releasing water in 2～3 days before grafting, optima 2 days; retaining 2～3 pieces of compound leaves at the same time; operating accurately and skillfully and completing the individual plant grafting within 1 minute ,which could raise the walnut budding take evidently.更多还原
