伤流是影响核桃大树改造嫁接成活率的关键性因子。通过几年探索,我们研究出通过改变锯砧木的方法减少了伤流对嫁接口的影响从而提高嫁接成活率,此法将砧木锯成双斜面,锯口形状呈“V”字形,总结为“双斜锯砧”嫁接法。 Injury is the key factor affecting the survival rate of walnut tree transformation grafting. Through several years of exploration, we have found that the method of sawing saw stock can reduce the impact of wound flow on the grafting interface so as to improve the graft survival rate. The method saws the stock root into double bevels, and the shape of the saw mouth is “V”. For the “double-oblique saw anvil ” grafting method.
