| Abstract: | Using field test method,the nutrition characteristics and the fertilizer effect of hybrid rice Guangliangyou 476 were studied.The results showed that Guangliangyou 476 demanded more nitrogen and phosphorus early in the growing,and more potassium in the late.The optimum fertilization pattern of Guangliangyou 476 was N 190.9 kg/hm2,P2O5 90.0 kg/hm2,K2O 150.0 kg/hm2.Under this fertilization pattern,its yield could reach 9 651.5~9 810.8 kg/hm2. |
