绿豆在我国是重要的绿肥作物.1979年,我组从绿豆品资源中系统选育出粮肥兼用种“绿豆85”.折合亩产263斤,鲜草亩产3800斤.对收摘后的绿色部分初步分析:茎秆含氮1.33%,磷0.26%,钾2%,叶含氮2.44%,磷0.56%,钾1%嫩荚含氮2.91%,磷0.74,钾1.84%,高于一般绿豆养分含量.如每亩按4000斤鲜草产量,则可折纯氮20.8斤(按一般绿豆氮素含量0.52%计算),相当于100斤硫铵,磷钾养分也很丰富.1980年,在通许、临 Mung bean is an important green manure crop in our country .In 1979, our group systematically bred out the “grain of mung bean 85” from the mung bean resources in a systematic way, yielding 263 kg per mu and 3800 kg fresh grass per mu. After the green part of the preliminary analysis: stalks containing 1.33% nitrogen, phosphorus 0.26%, 2% potassium, leaf nitrogen 2.44%, phosphorus 0.56%, potassium 1% tender pod nitrogen 2.91% phosphorus 0.74 potassium 1.84% In the general mung bean nutrient content, such as per mu yield of 4000 kg of fresh grass, you can fold 20.8 kg of pure nitrogen (according to the general mung bean nitrogen content of 0.52% basis), equivalent to 100 kg of ammonium sulfate, phosphorus and potassium nutrients is also very rich .1980 Years, Tong Xu, Pro
