摘　　要：通过氮磷钾肥"3414"肥效试验,研究氮磷钾肥对水稻产量的影响。结果表明:不施或少施肥料不仅对水稻长势有影响,对产量也有不同程度的影响;氮肥对水稻的产量影响最大。The effect of NPK on rice yield was studied through the 3414 fertility efficiency experiment. The results showed that there was influence of different degrees on the growth vigor and yield of rice by no or little fertilization amount and the nitrogen fertilizer had the most influence on rice yield.
