| Abstract: | 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. |
