在早稻田进行紫云英还田、减量施用化肥试验,结果表明,每667 m2翻压紫云英2 000kg、减少20%～40%化肥施用量处理的早稻产量与习惯施肥没有差别,且改善土壤理化性状,提高土壤有机质含量,提高稻谷和秸秆中钾素含量及稻谷中氮素含量,经济效益显著,达到节本增收的效果。

Effect of incorporating milk vetch into field and reducing fetilizer amount on yield and benefit of early rice was studied in this paper.The results showed that compared with conventional fertilization,the yield that incorporating milk vetch of 2000kg/667m2（30000 kg/hm2）and reducing the applying amount of chemical fertilizer by 20%-40% was same to CK,improved soil physical and chemical character,increased soil O.M,the potassium contents in rice grains and straws and nitrogen content in rice grains,possessed significant economic benefit,reached the goal of saving cost and improving income.
