本文采用二元二次正交回归旋转组合设计试验方法，研究了小麦带距、玉米密度对地膜玉米产量的影响，建立了二因素与玉米产量关系的数学模型，模拟优化提出了适合黔西北山区应用的地膜玉米高产的小麦带距和玉米密度方案。
In this paper, Binary Quadratic Regression Rotation Combination Design Test Method was used to study the effect of wheat distance and corn density on the yield of plastic film maize. The mathematical model of the relationship between the two factors and corn yield was established. Application of mulching corn High-yielding wheat tape spacing and corn density programs.
