据报导,草木樨是华北地区一种良好的豆科绿肥。黄泛区农场于1961年开始作观察性栽培试验,初步明确二年生黄花草木樨在当地春秋播种都有良好的长势。为此,我们在1962年秋至1964年夏季进行了草木樨的麦田肥效试验,以当地惯用的夏季绿肥——绿豆为对比,研究草木樨秋播、春播、单播及套播的生长情况和肥效,井以当地主要的复种习惯为辅助处理,比较复种与单播绿肥的生产效益及土壤肥力的消长关系。试验设计如下:
It is reported that grass mulberry is a good legume green manure in North China. The pan-pan farms began an observational cultivation experiment in 1961, initially confirming that the perennial yellow mulberry trees have good growth in the spring and autumn seeding. Therefore, in the autumn of 1962 to the summer of 1964, we conducted the experiment of fertilizer efficiency on the wheat field of M. chinensis. By comparing the summer green manure and mung bean that is commonly used in the locality, we studied the growth and fertility of autumn and winter sowing, Wells were supplemented with the main multiplication habit of the local area to compare the production efficiency of single cropping green manure with unicast green manure and the growth and decline of soil fertility. Experimental design is as follows:
