我国大部分蚕区一直采用嫁接方式培育良种桑苗.嫁接技术要求高,且受季节限制,影响了各地(特别是新蚕区)良种苗木的生产和供应.为此,我们自1991年始多次进行了嫩枝扦插繁育试验,以期加快我区良种桑苗的繁殖.
Most silkworm areas in China have been using grafting methods to cultivate fine mulberry seedlings. Grafting requires high technology and is subject to seasonal restrictions, affecting the production and supply of fine seedlings all over the country, especially in the new silkworm area. Softwood cuttings breeding experiments were carried out in order to speed up the breeding of superior seedlings in our area.
