| 摘 要： | 目的]提高沿海滩涂土壤肥力,促进农业可持续发展。方法]在稻田布置了连续3年的冬种紫云英、蚕豆翻压还田,研究水稻-绿肥轮作对滩涂土壤肥力的影响。结果]与冬闲处理相比,绿肥还田能增加土壤有机质,提高土壤碱解氮、速效磷和速效钾含量。经过3年的稻-绿肥轮作,紫云英对土壤肥力的提升效果优于蚕豆,紫云英区土壤有机质和全氮分别提高了16.13%和14.81%。结论]稻-紫云英轮作是一种较好的轮作模式。

Effects of Rice-Green Manure Cropping Rotation on Soil Fertility of Mudflat |
| |
| Abstract: | Objective] To enhance the soil fertility of mudflat and to promote the sustainable development of agriculture.Method] Three-year field returning of milk vetch and broad bean on soil fertility was arranged in rice field.Effects of rice-green manure cropping rotation on soil fer-tility of mudflat were researched. Result] Compared with winter fallow treatment, returning green manure to field enhanced the organic matter in soil, enhanced the contents of soil alkali-hydrolyzable nitrogen, rapidly-available phosphorus and rapidly available potassium.After three-years rice-green manure rotation, milk vetch showed higher enhancement for soil fertility than broad bean.Soil organic matter content and total nitrogen content in milk vetch area enhanced by 16.13% and 14.81%, respectively.Conclusion] Rice-green manure cropping rotation is a relatively good rotation mode. |
