What is liquid mulch?

Liquid plastic film is a non-toxic, pollution-free, pollution-free, completely degradable film that does not contain heavy metals and other chemical components. After spraying, crops can emerge naturally without artificial introduction and release of seedlings. The operation is simple, saves time and effort, and the cost is low. It is not only a completely degradable mulch film, but also an organic fertilizer with good fertilizer efficiency. After spraying, a dark brown film will be formed on the surface of the farmland, which can increase the soil temperature of 5-15 cm by 2°C and advance the crop growth period by 3-5 days. At the same time, it can inhibit water evaporation and improve water utilization. The evaporation inhibition rate is above 30%, and the soil moisture content can be increased by more than 20%. Compared with ordinary PE mulch film, it is easy to use, saves time and effort, and has lower cost.

Advantages and Disadvantages of Liquid Plastic Film

Advantages of Liquid Plastic Film:

1. Biodegradable liquid plastic film can eradicate the problem of "white pollution" and increase agricultural production and income. and the purpose of comprehensive utilization of resources;

2. Biodegradable liquid mulch film has multiple functions: plastic mulch film can absorb heat, increase temperature, retain moisture, and protect seedlings; it has fertilizer effect and strong adhesion ability, and can Soil particles are connected into ideal aggregates, improving soil permeability.

3. Biodegradable liquid mulch film can improve the agricultural production environment due to white pollution, and has the characteristics of pesticides, fertilizers and agricultural mulch films.

4. Spraying pesticides in the field and making films saves labor and time. Pesticides and herbicides can be mixed into the plastic film and sprayed together to improve labor efficiency, save labor and have strong adaptability to terrain;

5. After the crops emerge, they can emerge naturally without artificial sowing.

Disadvantages of liquid mulch:

1. The liquid mulch currently on the market has the problem of short film formation time. It has poor drought resistance effect on plants in the later stage.

2. Because the dose during the film formation process is relatively small. The visual effect on the ground after film formation is not very good. It feels ineffective. In fact, it exists.

3. There is no toughness after the mulch film is formed. It is easy to crack when it reaches the surface.
