黄花菜的繁殖,一般都采用传统的分株方法,繁殖系数低,不能获得大量种苗以供大面积栽植和建立商品生产基地之需。近年来,我国一些黄花菜产区开始采用切茎繁殖的方法,据报道,此法比分株繁殖方法可提高繁殖系数4—7倍。但是,所见资料大都是一些侧重于切割方法的地区性经验,至于对影响切茎育苗的其它技术问题的研究尚未见报道。我们于 Day lily breeding, generally use the traditional ramets method, the breeding coefficient is low, can not get a lot of seedlings for large-scale planting and the establishment of the production base of goods. In recent years, some lily producing areas in China began to adopt the method of cutting stem propagation. It is reported that this method can increase the propagation coefficient by 4-7 times compared with that of strain. However, most of the information we see is based on regional experiences that focus on the cutting method. However, there is no report on other technical issues that affect the cutting of stems and seedlings. We are here
