残膜污染对棉花生产的影响及其治理

Effect of Leftover Film Contamination on Cotton Production and Its Administration

随着我国棉花生产的快速发展,地膜覆盖技术也日趋成熟,由此大大改善了棉花生产的土壤环境,增加了棉花产量。但是,随之产生的问题则是"白色污染"日益严重,在先进的生产条件下不能完全体现出地膜覆盖的优势,使得土壤物理条件恶化、棉花生长和发育受到一定抑制作用,同时在某种程度上降低了产量。为此,棉花覆膜栽培中"白色污染"的治理迫在眉睫,本文结合本地生产提出地膜选用、田间管理、残膜回收利用、制定相关政策及开发地膜应用新技术诸方面的改良的措施,以望能为棉花生产中残膜污染的治理提供一定依据。

With the rapid development of cotton cultivation in China, film covering technology is more and more maturating. It has improved soil circumstance of cotton growth and enhanced cotton yield. However, this technology makes “white pollution” serious day by day. In modern cultivating condition, the superiority of film covering has not been put up, soil physical circumstance becomes worse, cotton growth has been restrained, and cotton yield decreased in some degree. So, administration of white pollution in the course of cotton cultivation must be advanced on the agenda. In this paper, we offer some advice about film selection, cultivation management, film residue recycle, policy sanction and new technology application to for film contamination administration.
