Abstract
Using 311-A optimal fitting saturated regressive design , the regression model for ‘Shenliangyou 5814’ rice rotated after Tobacco was established with the factors in transplanting density , nitrogen rate and potassium rate .The results indicated that the effects of single factor on rice yield revealed in order of nitrogen rate >transplanting density > potassium rate .The interaction effect between two factors were in order as transplanting density and nitrogen rate > transplanting density and potassium rate > nitrogen rate and potassium rate .The optimum combination in factors was simulated with computer optimization ,which was in transplanting density 210 000 hills · hm-2 ,potassium rate (K2O) 138.1 kg · hm -2 and nitrogen rate (N) 143.4 kg · hm -2 for the highest rice yield in 8 908.18 kg · hm-2 .关键词
