塑料薄膜覆盖栽培是农业上一项新技术,不但用于园艺栽培,而且发展到应用于大田作物,覆盖面积不断扩大。在欧洲,目前用于马铃薯和蔬菜的覆盖面积为(公顷):西德1775,比利时1000,匈牙利1000,法国700,英国300。用于玉米的覆盖面积:法国5000,西德500,英国12。日本应用薄膜覆盖技术很早,发展速度也很快,现已有70000公顷覆盖面积,80%的蔬菜都是由薄膜覆盖地生产的。还有一些国家如苏联正在进行试验。 Plastic film covered cultivation is a new agricultural technology, not only for horticultural cultivation, but also developed to field crops, covering an expanding area. In Europe, the current coverage area for potatoes and vegetables is (hectare): West Germany 1775, Belgium 1000, Hungary 1000, France 700, United Kingdom 300. Coverage for maize: France 5000, West Germany 500, United Kingdom 12. Japan’s application of film covering technology very early, the rapid development, now has 70,000 hectares of coverage, 80% of the vegetables are produced by the film coverage. Still others, such as the Soviet Union, are experimenting.
