摘要
进行每667 m2紫云英鲜草1500 kg还田、后季稻减量施用化肥试验,结果表明:在相同紫云英鲜草还田量条件下,减少20%的测土配方推荐施肥量处理的水稻产量最高、效益最好;紫云英鲜草还田后土壤有机质含量提升明显。
An experiment of incorporating 1500 kg straw/667 m2 （22 500 kg/hm2 ） of Chinese milk vetch to field and reducing fertilization amount in succeeding rice crop were carried out. The results showed that when incorporating amount was the same, the yield and benefit were the best under the treatment of reducing fertilizer by 20%. And incorporating fresh straw of Chinese milk vetch could significantly improve organic matter in soil.
