(一)合理密植是棉花生产上一项简而易行,经济有效的增产措施。单位面积的皮棉产量,是由每亩株数,每株铃数、每铃籽棉重和籽棉的衣分四个因素构成。其中密度和单株结铃数是构成每亩总铃数,即棉花产量的主要因素。但在提高总铃数的同时,还必须重视增加铃重和提高衣分,才能获得高产、稳产。目前我省棉花生产上,密植方面存在
(I) Reasonable and close planting is a simple, cost-effective stimulation of cotton production. The lint yield per unit area is composed of four factors, including the number of plants per mu, the number of bolls per plant, the weight of cotton bolls per acre and the percentage of seed cotton. Among them, the density and number of bolls per plant are the main factors that make up the total number of bolls per acre, that is, cotton yield. However, while increasing the total number of bolls, we must also attach importance to increasing the boll weight and increasing the lint percentage in order to achieve high yields and stable yields. At present, cotton production in our province, dense planting there
