| 摘 要： | 通过大田双季稻轮作试验,研究了在农民习惯施肥的基础上,不同减少氮磷肥料用量的施肥措施对水稻生长、产量的影响。减施氮肥处理结果表明:比农民习惯施肥减施20%氮肥的条件下,施用缓释肥料(80R)产量最高,比传统不减少施氮处理(CFN)增产0.4%,比等养分量纯化肥处理(80F)增产6.0%;用有机肥和化肥配施的处理(30F+50M)比80F增产1.9%;绿肥和化肥配施的处理(50F+30A)比80F显著减产7.2%(P<0.05)。因此,施缓释肥料或用有机肥和化肥配施均能提高产量,减少氮肥施用量。减施磷肥处理结果表明:比农民习惯施肥减少施磷20%的处理均没有减产,说明在本地区减少施磷20%,具有一定的可行性。

| Abstract: | The effects of different fertilization reduction on double-crop rice growth and yield were studied on the basis of farmer conventional fertilization.The results of nitrogen reduction showed as follows.The highest yield was obtained with the application of slow release fertilizers.Compared to conventional nitrogen fertilizer application(CFN).0.4% higher yield was gained with 80R whose N application rate was 20 percent lower than that of local fertilizer application.In comparison to the treatment with equal a... |
