本试验采用二次通用旋转组合设计方法，研究了影响地膜马铃薯产量、效益及产量主要构成性状与氮磷钾用量、配比及地膜覆盖间的关系，获得了地膜马铃薯高产高效数学模型及最佳农艺措施组合方案，并在试验的基础上，进行生产示范印证，建立了地膜马铃薯产量效益与氮磷钾施用量数学模型，根据模型利用计算机模拟寻优，得到地膜马铃薯667m2产量高于3000kg，纯收益大于300元的农艺组合方案31组。该方案95％置信域为667m2施纯N8．4～11．4kg．P2O510．4～13．2kg，K2O5．2～6．4kg。措施中心值是：667m2施纯N10．1kg，P2O511．8kg．K2O5．8kg，N、P2O5、K2O的比值约为1：1．17：0．57。
In this study, the quadratic universal rotary combination design method was used to study the relationship between the yield and benefit of potato and the main components of yield, the amount of nitrogen, phosphorus and potassium, the ratio and the mulching of mulching, and the yield and efficiency mathematical model of mulching film potato Based on the experimental results, a demonstration model of production was established. The mathematic model of potato yield and N, P and K application was established. According to the model, the yield of 667m2 potato was higher than 3000kg 31 sets of agro-combinatorial programs with revenue greater than 300 yuan. The scheme 95% confidence domain 667m2 Shi Chun N8.4 ~ 11.4kg. P2O510.4 ~ 13.2kg, K2O5.2 ~ 6.4kg. Measure center value is: 667m2 Shi Chun N10.1kg, P2O511.8kg. K2O5.8kg, N, P2O5, K2O ratio of about 1: 1.17: 0.57.
