摘要
试验观察了11种降解地膜在土壤中的降解效果,结果表明,11种降解地膜在土壤中都有不同程度的降解,其中以青岛康文生物材料有限公司生产的康文3号降解地膜在土壤中的降解率最高,在180 d时的降解率为30.17%,其埋入土壤中的时间越长,降解率越高,因此认为,应用康文3号降解地膜可以有效的减少残膜在土壤中的积累,应大力推广。
The degradation effect of 11 kinds of degradable plastic film in soil is observed. The result shows that 11 kinds of degradable films have different degree of degradation in soil,Kangwen 3 biodegradable plastic film in soil is the highest,which the degradation produced by Qingdao Kang Biological Materials Co. Ltd. The degradation rate of 180 days is 30.17%,the longer buried in the soil,the degradation rate is higher. We all think the application of Kangwen 3 biodegradable plastic film can effectively reduce the accumulation of residual plastic film in soil,and it would be widely popularized and used in the near further.
