Background
The biodegradable mulching film refers to a plastic mulching film which can be degraded under the action of microorganisms under natural environment conditions. After the plastic film is corroded by microorganisms such as bacteria, fungi and actinomycetes, the polymer components are hydrolyzed, ionized or protonated due to the growth of cells, and are mechanically destroyed and split into oligomer fragments. Enzymes secreted by fungi or bacteria decompose or oxidatively degrade water-soluble polymers into water-soluble fragments to form new small molecule compounds until the water-soluble fragments are finally decomposed into CO2And H2O。
The biodegradable mulching film is a novel ground covering film, and is mainly used for ground covering to improve the soil temperature, keep the soil moisture, maintain the soil structure and prevent pests from attacking crops and diseases caused by certain microorganisms, thereby promoting the growth of plants.
The biodegradable mulching film in the prior art has a short degradation period, and when the biodegradable mulching film is applied to plants with a long growth period, such as Xinjiang cotton, the growth period of the cotton does not yet come, and the biodegradable mulching film is broken or loses efficacy due to degradation, so that the growth and harvest of the cotton are adversely affected.
