在我国人口多,耕地面积有限的情况下,迅速提高棉花单产是当务之急。在继承和发扬先进植棉经验的基础上,采取一系列以化学物质为主的农艺措施,如施用化肥和农药,试验、推广应用生长调节物质、除草剂以及其他化学物质,从而逐步实现棉花栽培过程化学化。对提高棉花单产和提高劳动生产率,将是简捷易行而见效快的一个途径。随着农业机械化、电气化的发展,化学化与之相辅相成,是整个农业现代化中不可缺少的一环。
In our country with a large population and limited arable land, it is imperative to quickly increase cotton yields. On the basis of inheriting and developing advanced cotton-planting experience, a series of agrochemical measures mainly based on chemical substances, such as the application of fertilizers and pesticides, testing, promotion and application of growth regulating substances, herbicides and other chemicals, are adopted to gradually realize cotton cultivation Process chemical. It will be a simple and effective way to increase cotton yields and increase labor productivity. With the mechanization and electrification of agriculture, the chemicalization complements each other and is an indispensable part of the entire agricultural modernization.
