摘　　要：马铃薯种植中地膜的使用量是十分巨大的,为降低地膜对土壤和生态环境造成的破环和污染,设置不同地膜覆盖试验,探讨马铃薯液态地膜覆盖效果,并进行效果评价。试验结果表明,功能性液态地膜覆盖的马铃薯产量比塑料地膜覆盖的低7.47%,但是减去地膜铺设、人工捡拾和破膜等成本后,功能性液态地膜覆盖的利润比塑料地膜覆盖的高4.58%。综合可降解液态地膜的经济效益和环保特性,认为功能性液态地膜是比较合适的选择。The amount of plastic film used in potato planting is very large.In order to reduce the damage and pollution to soil and ecological environment caused by plastic film,different plastic film mulching experiments were set up to explore the effect of potato liquid film mulching and evaluate the effect.The results showed that the yield of potato covered with functional liquid film was 7.47%lower than that covered with plastic film,but the net profit of functional liquid film was 4.58%higher than that covered with plastic film after deducting the cost of film laying,manual picking and film breaking.Considering the economic benefits and environmental protection characteristics of degradable liquid mulching film,functional degradable liquid film would be the suitable choice.
