Ecological weeding insect-expelling water-saving disease-resistant functional film

Abstract

The invention discloses an ecological weeding insect-expelling water-saving disease-resistant functional film. An upper layer is prepared from 6-10 percent of anti-aging master batch, 5-10 percent of europium dioxide reflecting master batch, 5-10 percent of gray master batch and the balance of superior linear polyethylene of which the melt index is 2; a lower layer is prepared from 5-10 percent of carbon black master batch and 90-95 percent of linear polyethylene; the materials are put into an inner layer extruder and an outer layer extruder respectively via high speed stirring for extrusion molding. According to the ecological weeding insect-expelling water-saving disease-resistant functional film, a dual-layer bicolor structure is adopted, so that water can be saved by over 30-35 percent, the yield is increased by over 20-30 percent, complete weeding and prevention and control of diseases and pests are realized in a pollution-free way, and remarkable economic benefit and social benefit are achieved.

Description

technical field [0001] The invention relates to a mulch film, in particular to a multifunctional film used in agricultural production, which has ecological effects and can play functions such as weeding, insect repelling, water saving and disease resistance. Background technique [0002] The traditional mulch film is usually a white transparent film, which is used for ground covering. It has the functions of increasing soil temperature, maintaining soil moisture, maintaining soil structure, preventing pests from invading crops and diseases caused by certain microorganisms, and promoting plant growth. It is widely used in agriculture. The application has achieved significant economic benefits. [0003] With the continuous development of agricultural technology, mulch films with special functions have appeared one after another, such as black mulch films that can prevent weeds and improve ground temperature, and gray reflective films that can repel insects and prevent diseases...

AI Technical Summary

Problems solved by technology

[0003] With the continuous development of agricultural technology, mulch films with special functions have appeared one after another, such as black mulch films that can prevent weeds and improve ground temperature, and gray reflective films that can repel insects and prevent diseases. It is usually a single-layer single-color, which makes each type of plastic film have a single function. In the process of agricultural production, in order to maximize the favorable growth environment for crops, it is often necessary to superimpose two types of plastic film with different functions, resulting in high input costs. , the labor intensity is high, which brings some inconvenience to agricultural production
