摘　　要： 利用"3414"试验设计方案开展水稻田间肥效试验,结果表明:在试验条件下,施用钾肥对水稻增产效果最好;水稻最高产量每667m^2 N、P_2O_5、K_2O施用量分别为9.8kg、3.8kg、9.1kg;当水稻达到最佳经济效益时N、P_2O_5、K_2O施用量分别为7.2kg、3.0kg、5.9kg。 Using ＇3414＇ test design scheme,a field fertilizer efficiency test on rice was carried out.The results showed that under this test conditions,the best yield-increasing effect was applying potassium fertilizer.The maximum yield of rice was received under the condition of applying N,P2O5 and K2O were 9.8kg/667m^2（147kg/hm^2）,3.8kg/667m^2（57kg/hm^2） and 9.1kg/667m^2（136.5kg/hm^2）,respectively.The best economic benefit of rice was received while applying N,P2O5 and K2O were 7.2kg/667m^2（108kg/hm^2）,3.0kg/667m^2（45kg/hm^2）and 5.9kg/667m^2（88.5kg/hm^2）,respectively.
