不同施肥和种植制度定位监测试验结果表明，早稻的地力产量高于晚稻；故晚稻的施肥效益高于早稻。冬种蔬菜具有明显的增产效果，冬种紫云英以及施有机肥的增产效果与只施无机肥的效果相近，且未显示明显的优越性；冬种蔬菜、稻秆回田和冬种紫云英均能改善土壤理化性质；休闲和缺素处理对土壤理化性质都有不良影响。试验期间土壤肥力未有根本改观，土壤的供肥能力仍处于氮、钾供应不足的土壤含量分级标准，各处理的代换性钙、镁含量偏低，而且土壤呈现酸化的趋势，且以纯无机肥处理的土壤酸化最严重。
Different fertilization and planting system Positioning monitoring test results show that the early rice yield is higher than late rice; Late rice fertilization benefit is higher than the early rice. Winter vegetables have a significant yield increase effect, the winter-type milk vetch and organic fertilizer yield effect is similar to the effect of inorganic fertilizers only, and did not show obvious superiority; winter vegetables, rice straw back to field and winter purple Yun-ying can improve soil physical and chemical properties; leisure and lack of treatment of physical and chemical properties of the soil have a negative impact. During the experiment, the soil fertility did not change fundamentally. The soil fertility was still in the grading standard of soil with insufficient supply of nitrogen and potassium. The substitutional calcium and magnesium content of each treatment were low, and the soil showed the tendency of acidification. Fertilization of soil acidification is the most serious.
