摘　　要：通过对不同绿肥植物地上绿色体产量及植株鲜样氮、磷、钾、粗脂肪、粗纤维等养分的测定,对不同绿肥品种的肥料价值和饲料价值进行综合评价。结果表明,供试各绿肥品种株高和地上绿色体还田量的顺序是禾本科>苋科>菊科>豆科>十字花科,其中禾本科的苏丹草最高,为109.5 t/hm2,肥料和饲料价值植株含量最高的是豆科的紫花苜蓿,其中阿尔冈金植株含氮0.77%,粗蛋白质4.82%,粗脂肪0.42%。红苋R104植株钾含量为供试绿肥品种之首,高达1.08%。In this study,through determined the plants yield on the ground and the contents of nitrogen,phosphorus,potassium,crude fat,crude fiber and other chemical constituents in fresh plants in different kinds of green manures,compared fertilizer value and fodder value between them.The results showed that the height and return yield of up ground green plant order was gramineae〉amaranthaceae〉asteraceae〉leguminosae〉cruciferae,the sorghum was the highest 109.5 t/hm2,the fertilizer and fodder value of alfalfa was the best in all,Medicago sativa l.Algonquin contains nitrogen 0.77%,crude protein 4.82%,crude fat 0.42%.Red amaranth R104 contains potassium 1.08% which was the most in all of green manure.
