摘要
采用田间小区试验,研究紫云英鲜草还田对水稻产量和经济效益的影响,结果表明:每667 m2翻压紫云英1 500～2 000 kg能促进早稻的生长发育,增加产量,提高经济效益;同时还能提高土壤速效养分含量,改良土壤,培肥地力。
An field plot trial on the effect of different mount of fresh milk vetch on rice yield and economic benefit was conducted.The results showed that it could hasten rice growth,enhance the yield and improve economic benefit;simultaneously,increase the contents of soil available nutrients and improve soil fertility when fresh milk vetch was incorporated into soil at the rate of 1 500-2 500 kg/667m2（22 500-37 500 kg/hm2）.
