一、化学调控的机理及效果化学调控是指用植物生长调节剂,如缩节胺、调节胺等调控棉花的生长发育,通过改善和协调棉花的一系列生理生化进程和形态将就,使棉花产量和品质得到提高。植物生长调节剂的调控作用包括以下几方面: 1.基本效应:用生长调节剂浸种和在棉花苗期、蕾期、初花期、盛花期喷洒,促使棉株根量增加、根系活力增加、叶片叶绿素含量增加、光合作用能力增强,改善棉铃内源激素水平,促进光合作用产物向棉铃运送,从而达到高产、早熟、优质。使用植物生长
First, the chemical control mechanism and effect Chemical control refers to the use of plant growth regulators, such as shrink amide, regulating amine growth and development of cotton control by improving and coordinating a series of physiological and biochemical processes and cotton will cotton so that Yield and quality are improved. Plant growth regulators regulate the role of the following aspects: 1. The basic effects: soaking with growth regulators and cotton seedling stage, buds, early flowering, full flowering spray, to promote cotton plant roots increased, root activity increased, leaves Chlorophyll content increased, photosynthetic capacity increased, improve boll endogenous hormone levels, and promote photosynthetic products transported to cotton bolls, so as to achieve high yield, precocious, high quality. Use plant growth
