【摘要】 为了寻找春季核桃简单易行、成活率高的嫁接方法,采用插皮接和腹切接两种方法,对核桃春季枝接进行了研究。结果表明:4月10日、4月15日、4月20日插皮接的成活率分别为85.4%、73.0%、94.4%,腹切接的成活率分别为81.5%、87.9%、87.9%;1a生枝条下段作接穗插皮接的成活率分别为97.2%、94.8%、93.4%,腹切接的成活率分别为92.1%、90.7%、92.0%,均最高。插皮接因接穗失水和接穗病腐导致接穗死亡的比例分别为14.7%、3.8%,腹切接的分别为17.1%、5.9%。插皮接和腹切接因失水死亡的接穗的上部、中部、下部枝段接穗比例分别为70.7%、25.4%、3.9%和61.4%、30.3%、8.3%,均有极显著的差异。更多还原

【Abstract】 In order to improve the survival rate of Walnut in spring,bark grafting and were used in this study. The results were showed that the survival rates of bark grafting in April 10th ,April 15th ,April 20th were 85.4% ,73.0% and 94.4% respectively ,and that of side grafting were 81.5%、87.9%、87.9%,the survival rates of bark grafting with the scion of the lower part of 1a branches were 97.2%,94.8% and 93.4%,and that of side grafting were 92.1%,90.7% and 92.0%. Death rates of bark grafting caused by water loss and rot disease of scion were 14.7% and 3.8%,and that of side grafting were 17.1% and 5.9%. There existed significant differences of death rates of bark grafting and side grafting caused by water loss with the upper part,the middle part and the lower part of the branch as the scions,that were 70.7%,25.4%,3.9% and 61.4%,30.3%,8.3%.更多还原
