柑桔春季高接换种通常采用切接、留大桩,春梢夏梢摘心促发新梢扩大树冠技术.然而高接换种过程中,存在着嫁接捆扎困难,嫁接成活率较低,摘心促梢较少,树冠恢复慢,投产迟,产量损失大的问题.为此,在几年高接换种实践基础上对上述常用技术方法作了一些改进,提高了嫁接速度和嫁接成活率,促进了树冠的迅速恢复,提早了投产时间,减少了产量损失. In the process of high exchange, there are many problems such as grafting and strapping, low grafting survival rate, topping Less shoots, slow recovery of crown, delayed production and large yield loss.Therefore, some improvements of the above common techniques and methods were made on the basis of several years of practice of high alternate exchange, which improved the grafting speed and grafting survival rate, Promote the rapid recovery of canopy, early production time, reducing the yield loss.
