摘    要:在浙江省金衢盆地研究了不同施氮量(0~262.5 kg/hm2)对两系杂交水稻品种深两优5814产量及产量构成因素等的影响。结果表明:深两优5814的最佳施氮量为225 kg/hm2,在此施氮量条件下,水稻产量最高,经济性状和农艺性状较优;过高的施氮量会使结实率和千粒重下降,从而导致产量有所下降。

关 键 词:深两优5814  产量  氮肥用量  金衢盆地

Abstract:The effects of different nitrogen fertilizer application rates(0~262.5 kg/hm2) on the grain yield and yield components of two-line hybrid rice Shenliangyou 5814 in Jinhua-Quzhou Basin of Zhejiang province were studied.The results showed that the optimum nitrogen fertilizer application rate for Shenliangyou 5814 was 225 kg/hm2.Under the condition of this nitrogen fertilizer level,this variety had the highest yield and better economic characters and agronomic traits.The application of exorbitant nitrogen fertilizer would decrease the yield of Shenliangyou 5814 due to the decline of setting rate and kilo-grain weight.
Keywords:Shenliangyou 5814  Yield  Nitrogen fertilizer application rate  Jinhua-Quzhou Basin
