利用3种生态降解地膜为供试材料,以普通聚乙烯地膜作对照,在山西省运城市进行棉田覆膜对比试验,观察生态降解地膜覆盖棉田的适用性和降解特性及其对土壤理化指标、棉花生育进程和农艺性状的影响。结果表明,生态降解地膜3号适合棉田使用,对土壤的理化指标和棉花的农艺性状无影响,降解效果较好。
Three kinds of eco-degradable mulching film were used as tested materials, and ordinary polyethylene mulching film was used as control. Cotton mulching comparative experiment was carried out in Yuncheng, Shanxi Province. The suitability and degradation characteristics of eco-degradable mulching cotton field and its effects on soil physical and chemical indexes, Effects of Cotton Fertility and Agronomic Traits. The results showed that the eco-degraded plastic film No.3 was suitable for cotton field and had no effect on physical and chemical indexes of soil and agronomic traits of cotton, and the degradation effect was better.
