| 摘 要： | 采用3因子5水平最优回归设计方法,建立了N、P、K肥与生姜产量的数学模型。由模型得知:①3个因子对产量的影响顺序为钾肥>氮肥>磷肥;②产量>58 500.00 kg/hm2、收入>91 000.00元/hm2的施肥方案为,施N(X1)331.44～427.98 kg/hm2,P2O5(X2)59.88～93.52 kg/hm2,K2O(X3)273.99～425.82 kg/hm2。

| Abstract: | A mathematical model is established by using three-factors and five-levels the best regression design method.The relations of Ginger production and its profit to potash,nitrogenous and phosphate fertilizer application have been studied.The result shows that the three-factors effects to the Chinese cabbage production and its profit is increasing with the applied order of phosphate,nitrogenous and potash fertilizer;that the optimum fertilizer application scheme is N 331.44～427.98 kg/hm2,P2O5 59.88～93.52 kg/hm2 and K2O 273.99～425.82 kg/hm2 if the production will reach over 58 500.00 kg/hm2,and if its profit will reach over 91 000.00 kg/hm2. |
