探讨用数学模型分析寻找小麦达到高产高效的栽培方法 ,建立了优质小麦新品种永良 15号的产量和效益数学模型。模型预测的产量和效益与生产示范结果相吻合。通过分析获得了单位面积 ( 667m2 )小麦产量50 0kg左右、效益 (含地皮费 ) 450元的最佳农艺措施为 :灌淤土上基本苗 4 3～ 4 8万株 ,施纯N 19.5～ 2 1.1kg、P2 O514.1～ 16.6kg、K2 O 8.9～ 12 .1kg。在示范中应用取得了较好的经济效益 ,为高效农业做了有益的尝试。

The mathematic model was developed to find the high yield and efficiency of wheat and to establish the mathematic model of yield and benefit of good quality new wheat variety Yongliang 15. The yield and benefit of the model prediction are consistent with the demonstration results of the production. Through the analysis, the best agronomic measures for yield per hectare (50 mkg) of wheat with a yield of 50kg per unit area (667m2) and a benefit of 450 yuan (including land fee) were as follows: 43,000 ~ 48,000 basal shoots on silt soil, 1.1kg, P2 O514.1 ~ 16.6kg, K2O 8.9 ~ 12 .1kg. The application of the model has achieved good economic benefits and made beneficial attempts for efficient agriculture.
