摘　　要：对红麻全秆地膜保温效果及生物降解性能进行了实际应用研究。结果表明 ,常规造纸方法制造的红麻全秆地膜具有与塑料地膜非常相近的保温性能 ,同时红麻全秆地膜具有很好的生物降解性能 ,埋在土壤中 1 0周后 ,质量损失超过了 50 % ,强度损失接近 1 0 0 % ,约 3 5月后可自行降解消失。因此 ,添加壳聚糖的红麻全秆地膜完全可以替代塑料地膜用于农业生产。The function of heat preservation of kenaf mulch and its biodegradation behavior in field application were investigated.The results indicated that the mulch made of whole kenaf stalk by using conventional pulping and papermaking technology has very similar heat preservation function and much better biodegradation behavior compared with the plastic mulch.The weight of the kenaf mulch reduced 50% and its strength almost lost completely after it was embedded in the soil for 10 weeks.The kenaf mulch can be biodegradated and disappeared after 3.5 months in situ.It can be used as a substitute for the plastic mulch.
