摘　　要：通过大田试验,表明循环增效耕作模式(豆-稻-菜)比常规耕作模式(稻-稻-菜)土壤有机质增加0.26%,水稻产量每公顷增加504.0kg,周年三造每公顷增收人民币4298.0元,投入产出比提高0.31。实施豆-稻-菜种植结构具有资源循环再生,节本增效和改善生态环境等作用,是实现农业可持续发展的有效新途径。The applied effect on land corps shows that Effectively Recycling Cultivation Model （bean cultures-rice-vegetables） can improve the contain of organic matter of soil for 0.26% than Normal way （ricerice-vegetables）, the increase of production of rice is 504.0kg per hectare, thus the income of three harvest is 4298.0 RMB annually . The improvement of ratio of investment and output is 0.31. The Cultivation Structure of bean cultures-rice -vegetables applied can make the resources used recycling and regenerat- ed, the investment saved and the effect improved, the ecological circumstance would be improved too. It is a newly effective way to realize agricultural sustainable development. Key words： Effectively Recycling, Cultivation Model, Cultivation Structure, Soil nutrition, Sustainable development.
