摘　　要：为探寻最适合蔬菜生产的地膜,减少地膜对环境的污染,引导蔬菜产业绿色、健康、可持续发展,以4种类型地膜,即普通聚乙烯地膜(厚度0.01 mm)、可回收地膜1(厚度0.012 mm,聚乙烯加强地膜)、可回收地膜2(厚度0.014 mm,聚乙烯加强地膜)、全生物降解膜(厚度0.01 mm)为供试材料,以番茄品种普罗旺斯为供试作物,对比分析可回收地膜和可降解地膜与普通聚乙烯地膜的差异。结果表明,可回收地膜2在提高作物产量和促进植株生长方面具有明显优势,并且可回收率最高;可降解地膜在作物生长过程中并没有表现出明显优势,但降解率可以达到96.20%,因此建议在蔬菜种植过程中,越冬茬和冬春茬蔬菜生产推荐使用高强度可回收地膜,蔬菜越夏和秋延生产推荐使用可降解地膜。In order to explore the most suitable mulching film for vegetable production and reduce the environmental pol-lution of mulching film,four types of mulching film namely ordinary polyethylene mulching film(thickness 0.01 mm),recyclable mulching film 1(thickness 0.012 mm polyethylene reinforced mulching film),recyclable plastic film 2(thick-ness 0.014 mm polyethylene reinforced plastic film),and the whole biodegradable film(thickness 0.01 mm)were used as the test material,and tomato variety Provence was used as test crop,and the difference between recyclable and degradable plastic film and common polyethylene plastic film were compared and analyzed.The results showed that recyclable mulching film 2 can improve crop yield and plant growth during vegetable growth,and has the highest recovery rate.De-gradable mulch film did not show advantage in the process of crop growth,but the degradation rate could reach 96.20%,Therefore,it is recommended to use high-strength recyclable mulch film for winter and spring vegetable production,and biodegradable mulch film for summer and autumn vegetable production.
