核桃嫁接成活率较低。本试验旨在通过控制温度提高嫁接成活率。结果表明：当温度控制在２７℃左右，保持３４天，嫁接成活率可达７６６％；不同优良类型嫁接成活率无显著差异；不同嫁接时间对嫁接成活率没有影响。
Walnut grafted lower survival rate. The purpose of this experiment is to increase the graft survival rate by controlling the temperature. The results showed that when the temperature was controlled at about 27 ℃, the survival rate of grafting reached 766% for 34 days. There was no significant difference in grafting survival rate between different grafting types. Grafting time had no effect on grafting survival rate.
