草木樨是我省一种比较好的豆科绿肥植物。种子细小,播种时用种量少,生长期间固氮能力强,植株体内氮素含量很高,据我所化验室多年来的分析结果:掩青时一般地上部鲜草含氮量为0.58—0.70%。与其它夏绿肥相比,以干重计算:每1000斤草木樨干草平均含氮素27.7斤,太阳麻平均有26.8斤,田菁24.8斤,绿豆平均只含17.5斤,从氮素含量来看,草木樨可以称为夏绿肥之“王”。 Meadow mulberry is a better legume green manure in our province. Seeds are small, with less seeds when sowing, strong nitrogen fixation during growth, and high nitrogen content in plants. According to the analysis results of our laboratory over the years, the nitrogen content in the upper fresh grass is generally 0.58-0.70 %. Compared with other summer green manure, calculated on a dry weight basis: for every 1000 kg of hay, hay averaged 27.7 kg of nitrogen, 26.8 kg of sumatra, 24.8 kg of Sesbania, and mung bean averaged only 17.5 kg. From the perspective of nitrogen content , Vegetation can be called summer green manure “king.”
