为了探究砧木直径、立地条件及气候因子3个因素对核桃嫁接成活率和生长量的影响,分别于2013年5月下旬和12月中下旬,以采自西北农林科技大学的“香玲”、“西林3号”、“西洛2号”核桃良种接穗为试材,分别对宁陕县江口镇和商州区腰市镇核桃嫁接成活率及生长量情况进行了调查。结果表明:生产中对核桃实生树进行嫁接改造时,选择砧木直径在9~12cm的实生树可以保证较高的成活率;枝条长度生长量与砧木直径呈正相关;平地的核桃嫁接成活率及生长量均较坡地好;降雨量对核桃嫁接成活率及生长量至关重要。该研究可为生产中提高核桃嫁接成活率和生长量提供依据。
In order to explore the rootstock diameter, site conditions and climate factors three factors on the grafting survival rate and growth of walnut, respectively, in late May 2013 and late December, collected from the Northwest A & F University “,” Xilin 3 “,” Xiluo 2 “” walnut seedling scion as the test material, respectively, Ningshan County Jiangkou Town and Shangzhou District waist City grafted walnut survival rate and growth were investigated . The results showed that in the process of grafting and rebuilding the walnut tree, the survival rate of the rootstock with the diameter of 9 ~ 12cm could be guaranteed. The growth of the branch length was positively correlated with the diameter of the rootstock. The graft survival rate and growth of the walnut The amount of rainfall is better than the slope. The rainfall is crucial to the survival rate and growth of walnut. This study can provide the basis for improving the survival rate and growth of walnut grafting in the production.
