| 【目的】研究有机无机肥配施对水稻主要性状、产量及土壤环境和地力的影响，探索有机无机
肥配施中纯氮的适宜配比。【方法】在南方双季稻田进行田间试验，按随机区组设计，在等氮、磷、钾量条件
下，通过设置氮磷钾化学肥料（T1）、80% 化肥 +20% 有机肥（T2）、60% 化肥 +40% 有机肥（T3）、20% 化
肥 +80% 有机肥（T4）、有机肥（T5）和不施肥（CK, T6）6 个处理，研究不同施肥处理间水稻的产量、有效穗
数、秸秆干重等差异以及土壤理化性质的变化。【结果】20%~40% 有机肥纯氮供应比例的施肥处理能够增加
水稻的有效穗数，降低秸秆干重 6.1%~6.9%，氮肥农学效率较高；土壤 pH 值变化不明显，能使土壤有机质含
量增加 6.9%~31.5%。【结论】有机无机配施有利于减少化学肥料的使用，有机无机肥配施中纯氮供应比例在
20%~40% 间对提高水稻产量和降低氮肥环境负效应的综合效应最佳，肥料效益和生态效益显著。 |

| 【Objective】The study was to reveal the effects of combined application of organic and inorganic fertilizers
on main agronomic traits and yield of rice, soil environment and soil fertility, and explore the proper proportion of pure
nitrogen in the combined application of organic and inorganic fertilizers.【Method】Field trials were conducted in southern
double-cropping rice fields, and a randomized block design with six treatments, including 100% NPK chemical fertilizer（T1）,
80% NPK chemical fertilizer + 20% organic fertilizer（T2）, 60% NPK chemical fertilizer + 40% organic fertilizer（T3）,
20% NPK chemical fertilizer + 80% organic fertilizer（T4）, 100% organic fertilizer（T5）and no fertilization（CK, T6）,
was conducted to compare the differences in rice yield, effective panicle number, rice straw dry weight, and changes in soil
physical and chemical properties.【Result】The application of 20%-40% pure nitrogen which came from organic fertilizer
could increase effective panicle number of rice and soil organic matter content of 6.9%-31.5%, reduce rice straw dry weight
of 6.1%-6.9%, show higher agronomic efficiency of nitrogen fertilizer and no obvious change in soil pH.【Conclusion】The
