摘　　要：通过对杂交水稻中优85施用氮、磷、钾配比施肥试验的产量分析及经济效益分析,结果表明:处理14产量最高(565.6 kg/667m2),比对照增产48.6%,经济效益较好,是一种理想、节本增效、经济效益较好的施肥配比方式。即在高海拔、中等肥力地区,以中氮(尿素21.74 kg/667m2)、低钾(氯化钾8.33 kg/667m2)、低磷(钙镁磷肥23.33 kg/667m2)为杂交水稻中优85最佳配比施肥方案。The results from analyzing yield and economic benefit of Zhongyou 85 under different N, P and K formula application indicate that the yield of the treatment with applying 21.74 kg/667m^2 of urea,23.33 kg/667m^2of calcium magnesium phosphate and 8. 33 kg/667m^2 of potassium chloride is the highest among all treatments, 48. 6% higher than CK and the optimum formula application with low cost and better economic benefit should be used for production of Zhongyou 85 in the regions with high elevation and moderate soil fertility.
