桃核芽接是繁殖优质核桃苗木的主要方法之一,但因嫁接时易产生伤流,故芽接成活率很低(只有35％或更低),生产中无法采用和推广这一技术。1978—1982年,我们在阿克苏地区实验林场进行试验,解决了芽接中的一些技术难题,成活率达85％左右。试验表明,芽接除了主要用于小苗嫁接外,还广泛用于核桃良种园的营建(先定砧后嫁接苗木)和已定植的不结果和结果少的劣质小树的改造(嫁接换头),也可用于2—4年生留床苗的嫁接。芽接具有节省穗材,方法简便,成本低,效果好等特点;芽接后的 Peach nuclear budding is one of the main ways to breed high quality walnut seedlings. However, it is very low (only 35% or less) because of the easy wounding when grafting. Therefore, this technique can not be adopted and popularized in production. In 1978-1982, we experimented on experimental forestry farms in Aksu region to solve some technical problems in sprouting, with a survival rate of 85%. Experiments show that budding is mainly used for seedling grafting, but also widely used for the construction of walnut seed orchard (grafted seedlings after the first anvil) and the transformation of the poorly-made and small-tree trees (grafting and exchanging) Can also be used for 2-4 years stay in bed seedling grafting. Sprout then save ear materials, the method is simple, low cost, good effect and so on; Budding after
