草木樨(Melilotus alba)是我省旱地主要绿肥作物.本试验是观察了解草木樨的开花结荚习性及其与繁种和育种的关系,为培育草木樨新品种和提高种子产量提供参考.一、观测方法:1976-1978年对秋播二年生白花草木樨作过田间观察和定株调查,逐日观测其蕾花荚的发育过程,并测量开花期的营养生长状况.对观测取得的数据,进行纵横比较分析,从中找出草木樨固有的规律性.
Melilotus alba is the main green manure crop in the dry land of our province .This experiment is to observe the flowering and pod habit and its relationship with breeding and breeding in order to provide reference for cultivating new varieties and increasing seed yield. Observational methods: During 1976-1978, the perennial white perennial plants were surveyed and fixed plants were surveyed, the developmental process of their flower buds was observed daily, and the vegetative growth conditions at the flowering stage were measured. The observed data Comparison of vertical and horizontal analysis, from which to find out the regularity of vegetation.
