Abstract
The main effects of different nitrogen levels(pure nitrogen: B0=0kg/hm2,B1=180 kg/hm2,B2=210 kg/hm2,B3=240 kg/hm2,B4=270 kg/hm2,B5=300 kg/hm2) treatments and two phosphate fertilizer managements(A1: Phosphate fertilizer used only once as basal fertilizer,A2: Phosphate fertilizer used in two equal proportions as basal fertilizer and flower fertilizer) on the hybrid rice Yunguang 109(calcium content was 166mg/kg) were studied based on the precise and quantitative cultivation patterns in order to evaluate the main influences on its grain yield and its component factors.The results showed that the nitrogen levels and phosphate fertilizer managements had no effect on sticky waxy ratio of Yunguang 109,which was about 3∶ 1,indicating such character was dominated by genetic gene.In addition,there was no significant effect on the length,width and length width ratio of Yunguang 109.The calcium content of grains in A2(the highest content was 198.7 mg/kg in A2B4) was significantly higher than that in A1(the lowest was 95.31 mg/kg in A1B0),indicating that the calcium content of grains could be improved by the phosphate fertilizer management.
