摘要
通过D-饱和最优回归设计田间试验测得的参数,分别建立以皮棉(y1)霜前花(y2)为目标函数的数学模型,经模拟仿真,因素取值的频率分析得出亩产皮棉高于90kg,霜前皮棉高于70kg,兼顾高产优质,氮磷、缩节胺优化配方为纯氮10.22~10.94kg/亩,P2O58.89~11.08kg/亩,喷缩节胺5.07~6.24g/亩,与此同时,并对单因素效应及互作效应作了剖析.
According to the parameters obtained from D-saturation best regression desing and field experiment, the mathematical model is established using ginned cotton (Y1) and the one before frost(Y2)as objective function. Based on the simulation and freguency analysis of factor allo-cation, optimized N, P, and DPC fertilizer-applying scheme which benefits fine quality as well as high yield is worked out. pure N 10.22 ̄10. 94kg per mu, P2O5 8. 89 ̄11. 08kg per mu, PPC 0. 57 ̄6.2g per mu. The single-factor effect and mutual effects is analysed.
