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。 Using D-saturation optimal regression design, the lube quadratic regression model was established with the lint yield as the goal. The mathematical calculation shows that the best fertilization method and the amount for Huimanfeng in cotton planting in spring and summer are as follows: The soil was sprayed with 192.82ml / mu, and 168.01ml / mu was sprayed on the leaves of the cotton plants before budding. The lint yield per mu was 10.78kg, an increase of 14.92%. The net profit per mu was 114.93 yuan.
