核桃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,故芽成活率很低。我县进行几年试验,对已定植的不结果的或结果少的小树改造,接后的苗木适应性强,结果早、果实产量和品质也有提高。其具体技术如下:一、砧木的培育芽接所用的砧木可用桃核、野核桃等,秋天在母树上采充分成熟、籽粒饱满的种子,当年秋播或翌年春播,培育砧木苗。播种前施足基肥,土壤深翻整平 Walnut bud then is one of the main methods of breeding high-quality walnut seedlings, but easy to produce wounds when grafting, so bud survival rate is very low. My county for several years of trials, has been planted fruitless fruitless or small tree transformation, followed by adaptability of seedlings, early results, fruit yield and quality also increased. The specific techniques are as follows: First, the rootstock nurturing Budding used peach kernel, wild walnut, etc., in the mother tree in the fall harvest fully mature, full-bodied seeds, when the autumn sowing the following year or spring, cultivate rootstock seedlings. Shizujifei before sowing, soil deep plowing flat
