| 摘 要： | 通过对四种可降解地膜降解特性的比较,结果表明,在紫外光条件下,B-1#的地膜失重率明显大于其他几种地膜的失重率;电镜和红外光谱分析可得到:几种可降解地膜的表面和内部结构均受到了不同程度的破坏,说明可降解地膜的降解程度还受其诱导期的影响;在不同土壤的生物降解过程中,X-1#的地膜放出的CO2的累积量远远高于其他几种地膜;说明了X-1#的生物降解速率要高于其他几种可降解地膜。

| Abstract: | The degradation characteristic of 4 mulching film was compared.The results showed that the weight loss rate of B-1# significantly exceeded the others in the ultraviolet rays conditions.Electron microscopy and infrared spectroscopy analysis showed that degradable mulching film’s surface and internal structure damaged with the ultraviolet irradiation.It indicated that the degree of degradation were influenced by induction period.CO2 released from X-1# was far more than the other films in the biological degradation process of different soil.It showed that the biodegradation rate of X-1# was the highest. |
