摘要
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。
To study the effect of rootstock diameter,climatic factors and site conditions on the survival rate and growth of grafting walnut,fine scion of ＇Xiangling, ＇Xilin No 3 ＇Xiluo No. 2＇ selected from Northwest Agricultural and Forestry University were used as test materials,survival rate and growth of grafting walnut were investigated in Ningshan County and Shangzhou district at the end of May and December in 2013. The results showed that, trees with rootstock from 9 cm to 12 cm diameter displayed higher survival rate,branches length increment and rootstock diameter were positively correlated,grafting walnut was feasibly in ground, and rainfall had a great influence on the survival rate and growth of grafting walnut. This study provided a basis for improving the survival rate and growth of grafting walnut in production.
