摘 要: | 淀粉—聚乙烯膜(指淀粉与聚乙烯按比例共混吹制的膜)在半干旱中早熟玉米区试用,可较好地协调土壤水肥气热状况,促进玉米前期生长发育,获得增产。淀粉—聚乙烯膜覆盖玉米能够提高农田增值率达24.2%,而且比纯聚乙烯膜投入降低,并且具有聚乙烯膜所不及的降解性,因而为半干旱地区耕作栽培增添了新的覆盖材料。

Abstract: | Starch-polyethene functional film was utilized on the medium-early maturing maize In semiarid areas.It can adjust the relationship of water,fertilizer,air and heat,promote the Growht and development of maize and result in higher yield.This practice not only reduced inputBut also raised output in production.In also provides a new way for mulching cultivation in semiArid areas. |
