核桃嫁接由于受伤流和单宁的影响,嫁接难度大,技术要求高,是目前国内核桃科研中最活跃的一个领域,也是今后核桃栽培中主要的一个技术推广项目。采用嫁接培育的核桃苗木比实生苗栽培的核桃树早结果5~7年,而且品质优良,产量高,主要是保证了优质品种优良特性的稳定传递,还可解决实生苗后代分离大的问题。现将具体嫁接技术介绍如下:一、砧木苗的处理选用普通播种的实
Due to the influence of injury flow and tannin, the grafting of walnut is difficult and the technical requirements are high. It is one of the most active fields in the research of walnut at present in China. It is also one of the major technology popularization projects in walnut cultivation in the future. The walnut seedlings cultivated by grafting are 5 to 7 years earlier than the walnut trees planted with seedlings, and are of good quality and high yield, which ensures the stable transmission of the superior characteristics of the high-quality varieties and can also solve the problem of large separation of the progeny of the seedlings. The specific grafting technology now introduced as follows: First, the stocking of seedlings selection of ordinary sowing
