| Abstract: | A mathematical model was established by using the best regression design method with three-factors and five-levels.The relations of Chinese cabbage production and its profit to nitrogenous,phosphate and potash fertilizer application was studied.The result shows:the three-factors affected on the Chinese cabbage production and its profit was increasing with the applied order of phosphate, nitrogenous and potash fertilizer;the optimum fertilizer application scheme was N:271.78～360.21?kg/hm 2;P 2O 5:112.35～146.70?kg/hm 2 and K 2O:133.80～206.55?kg/hm 2,so that the production would reach to over 97?500?kg/hm 2 and its profit would reach to over?14?250?yuan/hm 2. |
