摘要：

【摘要】：通过“3414”回归最优设计原理设置的水稻肥效试验，研究配方施肥对水稻农艺性状和产量的影响，以及施用氮磷钾肥的肥料效应。试验结果表明：与对照(CK)相比，各配方施肥处理水稻的各农艺性状和产量均有所提高；14个处理中以N2P2K2处理（每公顷施N 180kg、P 90 kg、K 67.5 kg）的水稻产量最高，为10234.5kg/hm2；用二次回归分析，得出每公顷最佳施肥量为氮肥191.55kg，磷肥95.85 kg，钾肥64.80 kg。综合肥料间互效拟合成功的方程和最佳经济施肥量，结合当地农业生产实际和施肥经验，建议推荐水稻每公顷施肥量为氮肥188~192kg，磷肥85~90 kg，钾肥63~66 kg。

Abstract:

Abstract: An experiment was carried out to study the effect of formulated fertilization on agronomic characters and yield of rice according to the theory of“3414”regression optimum design, and studied experiment of fertilizer by N、P、K. The results show that, Effect of formulated fertilization on agronomic characters in the different treatment of rice, and actual yield of each fertilizer treatment was enhanced by comparing with CK, in the field of middle levels of N, low P and K, application of N 180 kg/hm2, P 90 kg/hm2, K 67.5kg/hm2 can reach the highest yield of 10234.5kg/hm2. Regression recommended that the optimum fertilizing quantity of N, P, K is N 191.55 kg/hm2, P 95.85 kg/hm2and K 64.80 kg/hm2. N 188~192kg/hm2, P 85~90 kg/hm2 and K 63~66 kg/hm2 are strongly recommended by equation of experiment of fertilizer and the best fertilization, and experience of spread manure in agriculture.
