在甘肃省洮岷高寒二阴区农田生态条件下，采用裂区与二次回归结合的设计方法，多点同步研究影响地膜小麦高产优质高效与氮磷钾施用量配比间的关系和相关效应，并在试验的基础上同时进行生产示范验证，建立地膜小麦持续高产施肥数学模型。根据模型选用相应分析程序进行计算机模拟寻优，得到地膜春小麦每公顷产量高于６７５０ｋｇ，纯收益大于３７５０元的技术方案９２套。该方案９５％置信域为每公顷施优质农肥６万ｋｇ，纯Ｎ１１９．８５ｋｇ～１５０．６ｋｇ，Ｐ２Ｏ５１２２．５５ｋｇ～１５４．０５ｋｇ，Ｋ２Ｏ５７．１５ｋｇ～７４．２５ｋｇ；措施中心组合是：每公顷施优质农肥６万ｋｇ，纯Ｎ１３５．３ｋｇ，Ｐ２Ｏ５１３８．３ｋｇ，Ｋ２Ｏ６５．７ｋｇ；Ｎ、Ｐ２Ｏ５、Ｋ２Ｏ的比约为１∶１．０２∶０．４９。
Under the farmland ecological conditions in the Min Aerial 2 and Apine in Gansu Province, by using the combination of split zone and quadratic regression, the multipoint synchronization study was conducted to investigate the relationship between high and high yield, high yield and efficiency, , And on the basis of the trial at the same time demonstration of production demonstration, the establishment of mathematical model of continuous high yield fertilization wheat. According to the model, the corresponding analysis program was used to optimize the computer simulation to obtain 92 sets of technical solutions with the yield of more than 6750kg per hectare and net income of more than 3750 yuan. The 95% confidence level of this program is 60000 kg of high-quality agricultural fertilizer per hectare, pure N119.85kg ~ 150.6kg, P2O5122.55kg ~ 154.05kg and K2O57.15kg ~ 74.25kg. The center of the program is: Fertilizer 60,000 kg, pure N135.3kg, P2O5138.3kg, K2O65.7kg; N, P2O5, K2O ratio of about 1: 1.02: 0.49.
