地膜覆盖栽培日本等国首先在蔬菜、果树生产中应用,以后又推广于烟草、花生、早稻等作物,一般增产30—50％。我国棉花地膜覆盖栽培研究也较早。1976年以来,山西省农科院棉花所在水地和旱地棉田进行了研究。试验指出,地膜覆盖对土壤理化性质及棉花生育都有良好作用。但盐碱地棉花地膜覆盖研究甚少。为此,我们于1981—1982 Film mulching cultivation Japan and other countries first applied to the production of vegetables and fruit trees and later promoted to crops such as tobacco, peanuts and early rice, generally increasing the yield by 30-50%. Cotton mulching cultivation in China earlier. Since 1976, Shanxi Academy of Agricultural Sciences cotton water and dry cotton fields were studied. The experiment pointed out that the plastic film mulching has a good effect on the soil physical and chemical properties and cotton growth. However, there is little research on the mulching of cotton in saline soils. To this end, we in 1981-1982
