摘要
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.关键词
