棉花的系统化调技术是近年来在棉花生产上兴起的新技术。它摒弃了以往的“对症用药防止徒长”的应急措施,变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,充分利用光热水肥资源达到壮而不旺,稳产高产。目前常用的化学药品是缩节胺(又名助壮素),应用缩节胺对棉花生长发育有四大作用。一是提高棉花根系活力,促进棉花早发。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前一天。二是系统化调可以改善棉花的冠层结构,塑造理想的株型。通过不同时期和用量诱导及调控株型的变化,使之有利于群体生长发育,改善棉田的生态环境和棉铃的分布位置,以不致于因增加密
The systematic transfer of cotton technology is a new technology emerging in cotton production in recent years. It abandons the former “symptomatic medication to prevent leggy ” emergency measures into a systematic adjustment of cotton throughout the growth period, directed induction, so that there is a reasonable cotton groups, the ideal plant type, make full use of light and heat fertilizer and resources to achieve Strong but not prosperous, stable and high yield. At present, commonly used chemicals are shrink amines (also known as mepiquatns), application of amines on cotton growth and development have four major roles. First, improve the vitality of cotton roots, promote cotton early onset. According to the test, the cotton sown after soaking with 200 ppm of amylin is one day earlier than the cotton soaked in the control fresh water. Second, systematic adjustment can improve the canopy structure of cotton and shape the ideal plant type. Through the different periods and the amount of induction and regulation of plant type changes, so that it is conducive to the growth and development of groups to improve the ecological environment of cotton and cotton boll distribution location, so as not to increase the density
