摘 要:研究了"3414"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。结果表明,与对照相比,各配方施肥处理的农艺性状与产量均有所提高。在14个处理中,N2P2K2处理的水稻综合性状表现最优,稻谷产量最高,每公顷产量为9 000 kg。二次回归分析得出每公顷最佳施肥量为氮肥210kg、磷肥81 kg、钾肥131 kg。根据氮磷钾肥料效应模型,结合当地农业生产实际和施肥经验,建议水稻每公顷施肥量为氮肥210~222 kg、磷肥81~106 kg、钾肥131~213 kg。An experiment was carried out to study the effect of "3414" formulated fertilization on agronomic characters and yield of rice and fertilizer effect was studied after application of N, P, K. The results showed that the agronomic characters of rice in the different treatments and actual yield of each fertilizer treatment effect of formulated fertilization were enhanced compared with the control group. Among 14 treatments, synthetic properity of rice is optimal in N2P2K2 treatment, and it could reach to the highest yield 9 000 kg/hm2. Regression analysis recommended that the optimum fertilizing quantity was N210 kg/hm2, P 81 kg/hm2, K 131 kg/hm2. According to local agricultural production and experience of fertilizer application,the fertilizing quantity of N 210~222 kg/hm2, P 81~106 kg/hm2, K 131~213 kg/hm2 has been recommended on rice based on NPK fertilizer effect model.
