Optimization of N,P and K fertilization for high density cultivation of the large-spike type hybrid rice, Jinfu 1 You 527,was conducted.Regression analyses between the cultivation conditions and rice yield and net income from the harvest were performed.The results showed that all factors examined had a significant effect on yield and net income.Using a computerized imitative screening method,the optimized number of rice bushes per hectare was 220 000 to 320 000,and the fertilization rates for N was 134.9-169.7kg/hectare,for P2O5 was 42.0-71.3kg/ hectare and for K2O was 75.5-133.5kg/hectare.
