根据农业系统工程原理和方法,对影响棉花产量和品质的播种期、施纯氮量、密度、喷缩节安和去早蕾等主要栽培措施,于1987、1988年进行了优化组合研究,即采用旋转回归设计,借助电子计算机,建立以棉花高产,优质、高经济效益等为目标函数的数学模型。通过模拟寻优,选出高产、优质、高效益的综合栽培措施决策方案。经反馈试验表明、增产效果和经济效益显著。
According to the principle and method of agricultural system engineering, optimized combination research was carried out in 1987 and 1988 on the main cultivation measures such as sowing date, nitrogen application rate, density, spraying safety and early buds that affect the yield and quality of cotton, that is, Using rotary regression design, with the help of electronic computer, a mathematical model with the objective function of cotton high yield, high quality and high economic benefit is established. Through simulation optimization, select high yield, high quality, high efficiency integrated cultivation measures decision-making program. The feedback test shows that the yield increase and economic benefits significantly.
