我县自1964年开展“农业学大寨”运动以来,皮棉单产连年稳定在130—140斤,就是在遇到较重灾害的1975年,我们战胜了灾害,仍夺得161斤的好收成。我们的主要经验是密植、在省肥的条件下争总桃夺好桃达到丰收。广大群众通过多年反复实践、比较,改稀植为密植,棉花密度基本稳定在每亩6500株左右。田间管理上采取促苗、稳蕾、攻铃的施肥原则,每亩用化肥25—30斤,基本上集中在花铃期使用,每亩20多斤。为确保棉花高产优质,还必须狠抓红蜘蛛、红铃虫的防治。
Since carrying out the “Agriculture Studies in Dazhai” Campaign in 1964, the lint yield has stabilized at 130-140 jin in successive years. In 1975, when we suffered heavy disasters, we defeated the disaster and still won 161 jin of good harvests. Our main experience is close planting, in the province under the conditions of fertility competition peach wins peach harvest. Through years of repeated practice and comparison, the majority of the people changed their planted plants into dense plants and the cotton density basically stabilized at around 6,500 plants per mu. Field management to take to promote seedling, buds, tapping the principle of fertilization, with 25-30 pounds of fertilizer per mu, basically focused on the use of flowers and bolls, 20 kilos per mu. To ensure the high yield and quality of cotton, we must also pay close attention to the prevention and treatment of red spider, pink bollworm.
