不同施肥方法对水稻农艺性状及产量的影响

Effects of Different Fertilization Methods on Agronomic Traits and Yield of Rice

为进一步提高水稻单产的施肥技术,釆用对比试验,进行了4种施肥方法对水稻生物学性状及产量的影响。结果表明:重底早追+穗肥施肥方法比底肥一次清和重底早追增产5.0%以上;"W"施肥方法比重底早追+穗肥增产7.82%,比底肥一次清和重底早追增产13.0%以上,其前期、中期、后期施氮比例为6∶2∶2。说明重底早追+穗肥施肥方法和"W"施肥方法增产效果十分显著。

In order to increase the yield of rice by improving the fertilizcation method,effects of 4fertilization methods on agronomic traits and yield of rice were studied.The results showed that the yield of rice under early applying basic fertilizer with spike fertilizer application was at least 5% higher than basic fertilizer application one time only and early applying basic fertilizer only,yield of rice under＇W＇fertilization method was 7.82% higher than early applying basic fertilizer with spike fertilizer application,higher than basic fertilizer only and early applying basic fertilizer only at least 13%,nitrogen fertilizer proportion of＇W＇fertilization method was 6：2：2.It indicated that early applying basic fertilizer with spike fertilizer application and＇W＇fertilization method can increase the yield of rice obviously.
