摘要
采用D─饱和最优回归设计,以皮棉产量为目标,建立二元二次回归模型,经数学运算得出:惠满丰在春育夏栽棉花上最佳施肥方法及用量为,移栽沟土壤喷施192.82ml/亩,及现蕾前棉株叶背喷施168.01ml/亩,每亩增收皮棉10.78kg,增产14.92%,每亩纯利润114.93元。
This paper puts forward the binary quadratic regression -model by using D-saturation regression design for high yield. The best method and quantity of spreading KOMIX on spring-culitivated summer cotton is 192. 82ml per mu intransplant soil, 168. 01ml per mu on the back of cotton leave before squaring. The lint increases 10. 78kg by14. 92 percent and makes 114. 93 yuan pure profit per mu.
