摘  要：
采用田间小区试验,研究不同氮肥增效剂在水稻上的应用效果。结果表明:氮肥增效剂增产效果明显,有效穗数和每穗粒数显著增加。添加双氰胺的增产效果最好,产量达到7982.8 kg/hm2,添加氢醌和复合增效剂的产量分别为7922.9和7892.2 kg/hm2,增产幅度在4.95%~6.15%之间。氮肥增效剂增加水稻养分含量和积累量,提高肥料利用率,氮磷钾肥料利用率分别提高4.22%~8.44%、3.87%~7.40%、2.90%~8.72%。添加双氰胺的氮钾肥料利用率最高,分别达到64.21%和48.45%。

摘  要：
Field experiment was conducted to investigate effects of different nitrogen fertilizer synergists on rice yield and nutrients use efficiency. The results showed that nitrogen fertilizer synergists evidently improved yield of rice by significant increasing of effective panicles and grain number per panicle. The yield increasing effect of dicyandiamide treatment was the best,and its yield reached to 7982. 8 kg / hm2. The yield of hydroquinone and compound synergist treatment was7922. 7 kg / hm2 and 7892. 2 kg / hm2 respectively. Nitrogen fertilizer synergists could increase the nutrient content and accumulation of rice and improve the fertilizer use efficiency,N,P and K fertilizer use efficiency was increased by 4. 22% ~8. 44%,3. 91% ~ 7. 40% and 2. 90% ~ 8. 72%,respectively. In this study,N and K fertilizer use efficiency in dicyandiamide treatment was the highest,which reached to 64. 21% and 48. 45% respectively.
