Insect-prevention wood-prevention degradable environment-friendly mulching film

Abstract

The invention discloses an insect-prevention wood-prevention degradable environment-friendly mulching film. The insect-prevention wood-prevention degradable environment-friendly mulching film comprises an outer-layer mulching film and an inner-layer mulching film, wherein the outer-layer mulching film comprises the following components in percentage by weight: 30% of metallocene polyethylene, 35% of linear polyethylene, 5% of high-pressure polyethylene, 25% of light calcium carbonate, 3% of neem oil, 1% of atrazine and 1% of degradable master batch; the inner-layer mulching film comprises the following components in percentage by weight: 30% of metallocene polyethylene, 33% of linear polyethylene, 5% of high-pressure polyethylene, 1.5% of degradable master batch and 0.5% of a light stabilizer master batch. The insect-prevention wood-prevention degradable environment-friendly mulching film disclosed by the invention can be used for preventing various insects, inhibiting weeds, and preserving the temperature and water, has a natural degrading function, and finally can become nutrient substances of CO2, H2O and the like which are beneficial to the plant growth, and can be used for improving soil, and achieving the effects of saving petroleum, protecting environment, increasing yield and income, and benefiting nation and people.

Description

technical field [0001] The invention belongs to the technical field of agricultural materials, and in particular relates to a degradable and environment-friendly plastic film for preventing insects and weeds. Background technique [0002] my country is a large agricultural country with a large population. Agricultural issues are important strategic issues related to the national economy and people's livelihood. Plastic film has a good effect of increasing temperature and moisturizing, and can greatly increase the yield of crops. It is one of the important materials for agricultural production after seeds, chemical fertilizers and pesticides. The application of plastic film technology has greatly promoted the improvement of agricultural production and benefits. It has led to the change of agricultural production mode and the rapid development of agricultural productivity. [0003] In the current situation, the use of plastic film to grow crops has been widely promoted in agr...

Problems solved by technology

[0003] In the current situation, the use of plastic film to grow crops has been widely promoted in agriculture to achieve stable and high yields and significant benefits. However, it is difficult to recycle the use of plastic film, and the problem of white pollution is becoming more and more serious. The country has stepped up efforts to gradually promote environmentally friendly plastic film

However, the cost of degradable mulch is high, and it is difficult for farmers to accept it. In this case, we have invented a degradable and environmentally friendly mulch that prevents insects and weeds. Mulch
