The film made from biodegradable materials can be completely “Biodegradable”in nature through the action of microorganisms. The final products of degradation are carbon dioxide and water, no pollution to the environment, it was almost completely degraded in 180 days under aerobic composting condition. After many years of trial and application, the results showed that the effect was remarkable on the main crops such as cabbage, soybean and corn, and the yield was equal to that of common PE film. After being used, the plant remains can be tilled directly together with the degradable plastic film, without winding the machine. After one year, the plastic film can be basically degraded. The plastic film can be “Recycled in the field”without pollution and residue, and the next crop production will not be affected, the product performance is obviously higher than the national standard.

In the application, attention should be paid to the relatively poor toughness of the degradable mulch film, and the matching technique should be paid attention to (the field should be closed with preemergence herbicide before covering) , so as to avoid the damage of the longer mulch film and the poor effect of pressing grass in the later period.

In order to avoid the damage of long-time Mulch film and the bad effect of pressing grass in the later period, it is necessary to pay attention to the matching technique (applying preemergence herbicide to seal the field before Mulch) .
