摘要
为研究南方水网平原稻区绿肥还田效果,于2010-2011年连续设以紫云英为绿肥进行还田效果试验,结果表明:等肥料用量情况下,以1000kg/667m2的绿肥代替部分化学养分时,比单用化肥增产29.1～35.5kg/667m2,增幅6.0%～7.3%,增收64.08元/667m2,同时提高耕层土壤有机质含量3.1%。
The rice experiment of using Astragalus sinieus L. as green manure and reducing fetilizer amount were carried out. The result showed that when 1000kg Astragalus sinicus L. per 667m2 was used and the NPK which can provide by plant were reduced, the rice yeild could still increase 29.1 ~ 35.5 kg/667m2 at a rate of 6.0% ~ 7.3%, increase 64.08yuan/667m2. It also improved the content of organic matter in the topsoil layer.
