摘要： 为探索和建立云南紫泥田水稻施肥指标体系，通过“3414”回归最优设计原理设置水稻肥效试验，研究了紫泥田水稻氮磷钾施肥效应，拟合建立了氮、磷、钾因素与稻谷产量的肥料效应数学方程，初步建立了云南紫泥田水稻施肥指标体系。建议水稻高产量N、P2O5、K2O推荐施肥量分别为334.5~363.0 kg/hm2、31.5~288.0 kg/hm2、154.5~225.0 kg/hm2，目标产量9769.5~13191.0 kg/hm2；N、P2O5、K2O最佳施肥量分别为235.05~316.5 kg/hm2、7.65~252.0 kg/hm2、21.0~225.0 kg/hm2，目标产量9690.0~10183.5 kg/hm2。生产一百公斤稻谷所吸收的纯N为1.98 kg，纯P2O5为0.61 kg，纯K2O为2.64 kg；氮、磷、钾肥当季利用率分别为33.53%、7.66%、5.94%，氮、磷、钾肥综合利用率为48.02%；基础地力贡献率为62.78%。

Abstract: To establish the index of fertilizer recommendation for rice in purple paddy field in Yunnan, the experiment was carried out to study the effects of N, P and K fertilizer on rice in purple paddy field according to the theory of“3414”regression optimum design. Mathematical equation of fertilizer effect between yield of rice and N, P and K, was formulated. The index of fertilizer recommendation for rice in purple paddy field in Yunnan was established. Recommended fertilizer application of N 334.5- 363.0 kg/hm2, P2O5 31.5- 288.0 kg/hm2, K2O 154.5- 225.0 kg/hm2 could reach the highest rice yield of 9769.5- 13191.0 kg/hm2. Optimized fertilizer application of N 235.05-316.5 kg/hm2, P2O5 7.65-252.0 kg/hm2, K2O 21.0-225.0 kg/hm2 could reach rice yield of 9690.0-10183.5 kg/hm2. N 1.98 kg, P2O5 0.61 kg and K2O 2.64 kg were absorbed to produce 100 kg rice. The nutrient use efficiency of N, P and K was 33.53%, 7.66% and 5.94%, respectively. Fertilizer comprehensive utilization efficiency of N, P and K was 48.02%. The contribution rate of basic soil productivity was 62.78%.
