选用诱处 4号大豆和中豌 4号豌豆为供试作物 ,组建间作种植模式 ,并对其资源利用效果进行了测定。结果表明 ,其经济收益有了极大提高 ,产值是同类地小麦的 2 .54倍 ,玉米的2 .17倍 ;化肥氮的施用量较小麦、玉米减少近 2 / 3;经济产品的可消化粗蛋白是同类地小麦田的 1.6 5倍 ,玉米的 1.73倍 ;秸秆的可消化粗蛋白含量高 ,适口性好 ,单位面积所能提供的可消化粗蛋白是小麦秸的 2 1倍 ,玉米秸的 1.58倍。综合效益评价指数是同类地小麦的 3.4倍 ,玉米的 1.77倍。
Selection of No. 4 soybeans and peas peas 4 peas in the trial for the crop, set up intercropping mode, and its resource utilization were determined. The results show that the economic benefits have been greatly improved. The output value is 2.54 times that of the same kind of wheat and 2.17 times of that of corn. Compared with wheat and maize, the application rate of chemical fertilizer nitrogen is reduced by nearly two-thirds. The digestibility of economic products Crude protein is 1.6 5 times that of similar wheat fields and 1.73 times that of corn. The content of digestible crude protein in straw is high and its palatability is good. The digestible crude protein per unit area can provide 21 times of wheat straw, 1.58 times. The comprehensive benefit evaluation index is 3.4 times that of similar wheat and 1.77 times that of corn.
