摘要
在浠水县进行晚稻的"3414"试验,研究氮磷钾肥不同配施对晚稻经济性状和产量的影响。结果表明:氮肥对晚稻经济性状和产量影响最大,且氮肥对磷钾肥肥效的发挥有重要影响;综合考虑产量和经济效益得出,N、P2O5、K2O最佳施用量分别为169.85 kg/hm2、36.84 kg/hm2和80.94 kg/hm2。
The effects of combined application of N,P and K fertilizers on the economic characters and yield of late rice in Xishui County were studied by＇3414＇ fertilizer efficiency experiment.The results showed that N fertilizer had the most important effect on the economic characters and yield,and had important influence on the P and K fertilizers efficiency.Comprehensively considered the yield and economic benefit,the optimum amount of N,P and K fertilizers was 169.85 kg/hm^2,36.84 kg/hm^2 and 80.94 kg/hm^2,respectively.
