春玉米春大豆间作的种植技术研究

采用回归正交旋转组合设计的方法，选择春玉米间作春大豆的畦幅、春玉米密度、春大豆密度三个农艺因子，布置田间参数试验，通过对试验结果的分析，建立了春玉米间作春大豆的总产、春玉米产量、春大豆产量及净产值的三元二次回归模型。根据建立的模型，进行了因子效应分析，并结合计算机模拟寻优，对春玉米间作春大豆的畦幅及其复合群体结构进行了优化。

The Study on the Interplanting Technique between Spring Corn and Spring Soybean

The planting width of spring corn and spring soybean interplanting, density of spring corn and spring soybean were studied by designs of regression with orthogonal, rotable and composite and setting field parameter test. The second-order regression models were established about the total yield of spring corn and spring soybean interplanting yield of spring corn, yield of spring soybean and net value by analyzing the test results. The planting width of spring corn and spring soybean interplanting and the compound group constitution were perfected by factor efficiency analysis and computer simulation perfecting in the base of models.
