In agricultural production activities, mulching film plays an important role in restraining weeds, preserving water and soil moisture, and reducing nutrient loss. However, the plastic film residue generated by ordinary polyethylene (PE) plastic film in the process of use will destroy the soil structure, not only lead to the decline of soil fertility, but also cause a series of problems such as crop root development obstruction, yield reduction and environmental pollution.
Although the conventional mulch film is recycled by various means, due to its thin and fragile characteristics, some of it still remains in the soil, causing great harm to cultivated land, resulting in difficult germination of crops, difficult roots down, but also to agricultural mechanization operations have a greater obstacle, seriously affecting the enthusiasm of farmers farming, affecting the sustainable development of agriculture.
Biodegradable mulch film is made of materials that can be completely degraded by microorganisms in the natural environment, and environmental protection additives that are not harmful to the environment are added to blow molding. In agricultural production, it not only has the functions of traditional PE film such as moisture retention, temperature increase and weed control, but also does not need manual recycling after use, can be directly ploughed into the soil, and can achieve degradation in the soil, which is efficient and environmentally friendly.
What is the difference between biodegradable mulch film and other types of degradable mulch
At present, the types of degradable film on the market are divided into whole-biological type and additive type. The degradation products of fully biodegradable mulching film have no pollution to the environment. Additive degradable mulching film refers to the addition of degradable biomass or photosensitizers and oxidants in the production process of traditional polyethylene mulching film, and the small plastic particles generated after degradation still remain in the soil, and the safety is not clear, and there is a risk of secondary pollution.
The biodegradable mulch film has good tensile property, is not easily broken, is resistant to aging, is easy to recycle, reduces the residual time of mulch film in the soil, reduces the damage of soil residue, effectively controls soil pollution, ensures the crop emergence rate and the quality and safety of agricultural products, is conducive to the sustainable use of agricultural land, and ensures the quality and benefit of agricultural products.
