昭阳区低劣核桃嫁接改良试验

Improved Grafting Test of Inferior Walnut in Zhaoyang District

针对昭阳区历年来低劣核桃高枝嫁接成活率低的难题,在2012年进行了春季枝接与夏季芽接的对照试验。结果表明,枝接中,采用常规方法嫁接,成活率为52.7%,而采用蓄热保湿法嫁接,成活率则高达89.3%;在"方块形"芽接中,疤芽的位置不同,则成活率大不相同,枝条的年龄越大,则成活率越低。

Over the years, low survival rate of inferior walnut high branch grafting has been a problem in Zhaoyang District, control experiments of spring scion grafting and summer budding grafting were conduc- ted in 2012. The results showed that： in scion grafting, the survival rate was 52.7% by using conven- tional methods, while the grafting survival rate was up to 89.3% by using preserve moisturizing method; in ＂box-shaped＂ budding grafting, with different positions of buds , the survival rate were different, the older the branch was, the lower the survival rate was.
