摘要
目前新疆覆膜种植棉花面积超过170万hm2,但是由于南疆塔里木盆地春季风沙较大,风沙情况复杂,对塑料地膜破坏严重,重播率高;另外由于残膜不能及时全部回收,使耕地遭到严重的残膜污染。为此,对国内外风沙研究现状以及塑料等复合材料破损研究现状进行总结分析,并对新疆地区塑料地膜遭受风沙作用破坏的现状进行了调查分析,提出塑料地膜受风沙作用破损的防治措施,为新疆覆膜播种提供理论依据。
There are 1.7 million Ha cotton field in Xinjiang with film. The plastic film was damaged by frequent storm wind in southern of Xinjiang, Tarim Basin, it results in repeated seeding, and the agricultureland was polluted seriously by damaged film because it was not fully retrieved in time. In this paper we investigated and analysed the incurrent situa- tion of damaged film under sandstorm in Xinjiang through analysing the research incurrent situation of sandstorm and breakage of composite plastic film in demestic and overseas, at last we raised prevention and control measure of plastic film to resist sandstorm, it will provide theoretical basis for seeding with plastic film in Xinjiang
