How To Reduce The Pollution Of Agricultural Mulch Film

Agricultural film pollution refers to the use of agricultural film cover to maintain moisture or heat in the process of field tillage in order to promote the growth of crops, because it is difficult to degrade in the short term, destroying the soil structure, blocking the absorption of water and fertilizer by crops and thus affecting the growth of crops.
With the extension of the cultivation period of mulch mulching, a large number of agricultural mulch film remains in the soil, the decomposition rate of the mulch film is very slow, coupled with the low recovery rate of the residual film, the residual film in the soil continues to increase, resulting in soil pollution, resulting in a decrease in crop yield. Therefore, the effective prevention and control of mulch film pollution has become a problem to be taken seriously today. According to the experience and lessons learned over the past years, the prevention and control of agricultural mulch film pollution should carry out the following aspects.
1. Improve the quality of agricultural mulch film and improve the recovery rate of mulch film. If the thickness of the currently widely used mulch film is slightly increased and some anti-aging chemicals are added, it can not only extend the service life of the mulch film, improve its warming and moisturizing effect, but also facilitate clean recycling.
2. Combined with the actual production, improve agronomic technology and promote the recycling of mulch film. The main thing is to grasp the opportunity and determine a reasonable unveiling period. For example, the post-harvest unmasking of crops is changed to pre-harvest unmasking, and the unmasking period of crops is selected according to the actual situation of the region and the characteristics of crop growth. Choose to peel the film after the rain or when the soil is wet in the morning to improve the recovery rate of mulch film.
