摘　　要：以水稻岳优9113为对象,采用"3414"试验研究了化学肥料氮、磷、钾对水稻增产的效果。结果表明:施肥对水稻增产效果明显,与不施肥处理(CK)相比,13个施肥处理水稻平均增产25.1%;氮、磷、钾各养分的最高增产幅度分别为25.3%、14.9%和17.8%;从养分效率看,试验条件下施N 97.5 kg/hm2、P2O530 kg/hm2和K2O 75 kg/hm2时水稻增产效果最好。The effect of applying nitrogen fertilizer(N),phosphorus fertilizer(P) and potassium fertilizer(K) on the yield increase of Yueyou9113 was studied by 3414 experiment.The results showed that fertilization has obvious yield increase effect for rice.In comparison with non fertilization treatment(CK),the yield of rice in 13 fertilization treatments increased 1 340.9 kg/hm2 averagely,and the average increasing range reached 25.1%;the highest yield increasing rate of N,P and K was 25.3%、14.9% and 17.8%,respectively;from the view of nutrition efficiency,when fertilizer rate of N,P2O5 and K2O was 97.5 kg/hm2,30 kg/hm2 and 75 kg/hm2,respectively,the yield increasing effect of rice was the best.
