核桃是四大干果之一,具有很高的营养保健作用。嫁接是提高核桃品种化的重要手段,但由于嫁接后伤流及核桃枝条中含有单宁的影响,在砧穗结合处易形成氧化隔离层,嫁接方法、嫁接时期掌握不好,嫁接成活率较低,核桃嫁接是培育核桃优良品种苗木过程中最难掌握的一个关键环节。核桃嫁接包括室内嫁接和室外嫁接两种方式。笔者曾经从事优质早实核桃苗木的培育工作,进行核桃室内嫁接时,采用的嫁接方法是硬枝嫁接(双舌接)和子苗嫁接两种方法;进行室外嫁接时,采用的方法是方块形芽接。
Walnut is one of the four dried fruits, with high nutritional and health effects. Grafting is an important means to improve the varieties of walnut, but due to the injury after grafting walnut branches and the impact of tannin in the anvil spike at the junction of the formation of an easily oxidized barrier, grafting method, grasp the grafting period is poor, the graft survival rate Low, walnut grafting is the key to cultivate the best variety of walnut seedlings in the process of grasping a key link. Walnut grafting includes indoor grafting and outdoor grafting two ways. I have been engaged in the cultivation of high quality early seedlings of walnut seedlings, indoor grafting walnut, the grafting method used is grafting (double tongue) and seedling grafting two ways; for outdoor grafting, the method used is square budding .
