New biodegradable plastic film: a new breakthrough in agricultural environmental protection

In the field of agriculture, although the use of traditional plastic film has played an important role in increasing crop yields, its difficulty in degradation and long-term accumulation in the soil can cause soil pollution, affect soil aeration and permeability, and many other problems. The emergence of new biodegradable plastic films has brought hope for solving these problems.

This new type of plastic film is made of biodegradable polymer materials such as polylactic acid (PLA). In the natural environment, after a certain period of time, it will gradually decompose into harmless substances such as carbon dioxide and water under the action of microorganisms, and will not cause pollution to the soil.

In agricultural production, the new biodegradable plastic film also has good insulation, moisture retention, and moisture retention functions, which can effectively promote the growth and development of crops. For example, in some vegetable planting base experiments, plots using new biodegradable plastic film showed comparable germination rate, growth rate, and yield of crops compared to plots using traditional plastic film, and even performed better in terms of soil quality in the later stage.

At present, the new biodegradable plastic film has been promoted and applied in some areas. With the further reduction of production costs and the improvement of farmers' environmental awareness, it is believed that it will be widely used in the agricultural field nationwide and even globally, making important contributions to the sustainable development of agriculture.
