| Abstract: | Through the research on different nitrogen application ratio at vegetative and reproductive stages in rice,the results showed that the suitable nitrogen application ratio at vegetative and reproductive stages was 7: 3 so that the non-effective tillers were reduced,effective panicle rate increased,kernel set and 1 000-grain weight enhanced,and the yield increased by 40 kg/667 m2. |
