棉花的系统化调技术是近几年来在棉花生产上应用比较广泛,增产比较显著的新技术。变过去对症用药防止徒长的应急措施为棉花全生育期系统化调,定向诱导,使棉田有一个合理的群体,理想的株型,充分利用光热资源达到壮而不旺,稳产高产。1990、1991年位于黑龙港流域中心的衡水地区推广274.4万亩,平均亩增产皮棉12.1公斤,总增产皮棉3045.84万公斤,且具有简化管理、便于除虫,节省用工综合效果。 一、棉花系统化调的增产作用与效果 多年的试验研究和生产实践证明,棉花系统化调是一项简便有效的增产措施,其基本效应和主要作用是: 1.用缩节胺浸种可以提早齐苗,促进发根。据试验,用200ppm的缩节胺浸种之后播种的棉花比对照清水浸种的棉花齐苗期提早一天,二叶期调查,经过浸种的棉苗主根比对照长4.9厘米,侧根比对照多10.87条,第一片真叶的叶柄比对照短 Systematic transfer of cotton technology in recent years in cotton production more widely used, more significant new production technology. In the past, the emergency measures to prevent leggy growth of symptomatic drugs were systematic adjustment and directional induction throughout the whole growth period of cotton so that cotton fields had a reasonable population and an ideal plant type, making full use of light and heat resources to achieve strong growth while producing stable and high yields. In 1990 and 1991, 2.744 million mu of land was popularized in Hengshui area in the center of Heilongjiang River Basin. The average mu yield increased 12.1 kg of lint and the total output of lint cotton increased by 30.4584 million kg. Besides, it has simplified management, easy pest control and labor saving. First, the systematic adjustment of cotton yield-increasing role and effectiveness Years of experimental research and production practices have proved that the cotton system is a simple and effective stimulation of the stimulation measures, and its basic effects and the main role is: 1. With amide impregnation can be earlier Qi Miao, promote hair root. According to the test, cottonseed soaked with 200ppm polyamines was one day earlier than the control soaked cottonseed. In the second leaf stage, the main roots of soaked cottonseed were 4.9 cm longer than the control and 10.87 more lateral roots than the control, The first true leaf had shorter petioles than the control
