摘　　要：将脂肪族共聚酯PBSA完全生物降解地膜应用于甘蔗种植,探讨了PBSA完全生物降解地膜厚度和覆盖方式对甘蔗生长和地膜降解失重率的影响。结果表明:露光处理具有相对较高的甘蔗萌芽率和地膜降解失重率,但具有相对较低的甘蔗产量;地膜厚度为0.009 mm的处理具有相对较高的甘蔗萌芽率和产量,但具有相对较低的地膜降解失重率。The truly biodegradable mulch film made by aliphatic co-polyester （PBSA）were applied in sugarcane planting in this paper. The effect of sugarcane yield and mulch film＇s weight loss which was made by different thickness and covering ways of truly biodegradable mulch film were researched. The results showed that the treatment of exposition had higher sugarcane sprouting rate and mulch film＇s weight loss rate but lower sugarcane yield compared with the treatment of covering with soil. The truly biodegradable mulch film＇s thickness with 0.009 mm had higher sugarcane sprouting rate and yield but lower mulch film＇s weight loss rate compared with the thickness of 0.006 mm.
