First, the benefits of mulch

Mulch refers to a layer of film covering the surface of agricultural land, which is used to prevent evaporation of rainwater and inhibit the growth of weeds, and its benefits are as follows:

1. Prevention and control of pests and diseases: mulch can reduce pests and diseases attacking crops, preventing the roots from being infected by pathogens. At the same time, because the film can keep warm and reduce the temperature difference between day and night, it can help crop growth and reduce pests and diseases.

2. Insulation and moisturizing: Mulch can reduce the evaporation of water from the soil surface, increase the soil moisture content, and ensure that the crop growth water needs. At the same time, the film can also isolate the soil surface and the outside air temperature, increase the soil temperature, help crop growth and improve yields.

3. Improve yield: mulch can ensure crop ecological stability, reduce the impact of natural environmental factors, can improve yield.

Second, the bad side of mulch

Although mulch brings a lot of benefits, it also brings some negative effects:

1. Soil pollution: mulch film used for a long time, the soil will gather a certain amount of pesticides, fertilizer residues and other harmful substances, causing pollution to the soil. Meanwhile, once damaged, mulch film will release a large amount of garbage and pollute the surrounding environment.

2. Destroying the ecological environment: In the process of using mulch, it occupies land resources and affects the ecological environment, making the land lose its permeability and nitrogen-fixing ability, thus reducing the fertility of the land. At the same time, mulch film needs a lot of cleaning and disposal after use, which makes the amount of garbage generated increase and pollute the environment.

Although the use of mulch film has brought many benefits, it has also brought many negative effects in its use. Therefore, while using mulch film, we need to pay attention to its use time limit, try to take biodegradable materials, and do a good job of garbage disposal and cleanup, so as to maintain the balance and coordination of the ecological environment.
