快速繁殖大量良种桑苗,对发展蚕桑生产具有极其重要的意义。以往培育良种桑苗的方法,在浙江等地主要靠袋接繁殖,虽然袋接法有许多优点,但需时较长,土地利用率低,从播种到嫁接,最少需要一年半才能出苗。而且要在春季剪取接穗,也要减少一定数量的春叶收入。此外,如播种、嫁接还需要具备相当高的技术水平。
Rapid propagation of a large number of seedling mulberry seedlings, the development of sericulture production is extremely important. In the past, the method of cultivating seedlings of mulberry seedling mainly relied on bag propagation in Zhejiang and other places. Although the bagging method has many advantages, it takes a long time and low land utilization rate. It takes at least a year and a half to germinate from sowing to grafting. And scissors in the spring cut, but also to reduce the number of spring leaf income. In addition, such as planting, grafting also need to have a very high skill level.
