摘要
采用田间小区试验设置有机无机肥料配合施用的3个不同水平，与农民常规施肥作对照，研究有机无机肥料配合施用对水稻产量、产量构成因子和干物质积累及运转的影响。结果表明，在等商品有机肥用量条件下，配施适宜比例无机肥料处理与农民常规施肥相比，产量提高16．4％-22．6％，总干物质积累量提高18．8％～26．9％，均达极显著水平（P〈0．01）。同时，显著增加抽穗后干物质积累贡献率，降低茎叶物质转运率，从而实现增产。
A plot experiment was set with three different levels of the mixed application of organic-inorganic fertilizers. Compared with farmers fertilization practice, the effects of mixed applicationof organic-inorganic on the yield, yield components and dry matter accumulation, translocation of rice were studied. Results showed that yield and dry matter accumulation of rice increased by 16.4%-22.6% and 18.8%-26.9%, respectively, compared to farmers＇ fertilization practice, and both showed significant difference（P〈0.01） under the equal organic amount and appropriate proportion of inorganic fertilizer. And that CPA was significantly increased and TAR significantly reduced, which should be attribute to increased rice production.
