棉花喷洒生长调节剂,可以控制棉花的徒长,使其营养生长与生殖生长得到协调,以增加棉花的产量。1981年,我县在团结公社彭湾大队进行了棉花喷洒矮壮素的试验,面积达千余亩,取得经验后,随即在全县推广。1982年,全县喷施矮壮素的面积达29,358亩,喷施缩节安的面积744亩,即近30％的棉田都喷洒了生长调节剂。经喷洒生长调节剂的棉田,一股均有不同程度的增产效果,但是也有减产的。现将我县棉田试用生长调节剂的效应和技术总结介绍如下,以供参考。 Cotton spray growth regulator, you can control the growth of cotton so that its vegetative and reproductive growth are coordinated to increase the yield of cotton. In 1981, our county Peng Wan Brigade in unity community conducted a test of cotton spraying chlormequat, an area of ​​more than a thousand acres, gained experience, then in the county promotion. In 1982, the county sprayed CCC an area of ​​29,358 mu, sprayed an area of ​​744 acres contracted, that is, nearly 30% of the cotton fields are sprayed with growth regulators. Spraying growth regulators in cotton fields, all have different levels of stimulation, but there are also reduced production. Cotton County is now trial growth regulator effect and technology summarized below, for reference.
