通过秸秆还田大田试验，考察不同机械耕作方式对稻田土壤理化性质、水稻苗期生长状况及产量的影响。结果显示，不同机械耕作方式对稻田土壤物理性质影响不大，但旋耕铧犁处理可以显著增加土壤速效氮和速效磷含量；不同耕作方式对水稻初苗期生长有一定影响，但苗期结束时各处理间无显著差异；在稻田秸秆还田条件下，采用旋耕铧犁耕作方式可显著提高水稻产量。

Based on field experiments of straw returning,the effects of different mechanical tillage methods on soil physical and chemical properties,rice seedlings growth status and yields were investigated.The results showed that there was little effect of mechanical tillage methods on paddy soil physical properties,but the treat-ment of rotary tillage plough could significantly increase available nitrogen and available phosphorus of soil.Me-chanical tillage methods had a certain effect on the rice seedlings growth status in early seedling stage,but there was no significant difference among the treatments at the end of seedling stage.The rotary tillage plough treatment could significantly improve the rice yield with straw returning.
