麦棉两熟晚春套棉产量函数模型研究

Research on the Later Spring Sowing Cotton yield Model in the Double Groping System with Wheat and Cotton

在麦棉两熟制条件下,对晚春套棉花产量与播期、密度、喷施缩节安等三项主要农艺措施的关系进行了研究。建立了棉花产量与三项农艺措施间的函数模型,并对三因子间的交互作用做了详细分析,通过数学模拟筛选出籽棉产量较高的最佳农艺措施方案.

The study on the relationships between the later spring sowing cotton yield nad sowing dates, planting densities, DPC rates was conducted under the conditions of double cropping system with wheat and cotton. The parameter model between cotton yield and three agronomic measures was established, and the interaction between the three factors was analysed. The optimum combination of agronomic measures was selected through the mathmatical simulation.
