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

The ecological weeding expelling parasite disease-resistant functional membrane of economizing on water

Technical field

The present invention relates to a kind of mulch film, is a kind of for agricultural production specifically, has ecological effect, can play the multifunctional membrane of the functions such as weeding, expelling parasite, water saving be disease-resistant.

Background technology

The normally white hyaline membrane of traditional mulch film, being used for ground covers, has the raising soil temperature, keep soil moisture, keep soil structure, prevent disease that insect invasion and attack crop and certain micro-organisms cause etc., the functions such as Promoting plant growth, its application on agricultural has obtained significant economic benefit.

Along with agrotechnical development, the mulch film of specific function has also appearred having in succession, as has a black mulch film that prevents weeds, improves the ground temperature function, have expelling parasite, prevent the grey reflective membrane of disease generation etc., this class coloured functional mulch film is generally the individual layer monochrome, also just so that every kind of mulch film function is more single, in agricultural production process, advantageously grow environment for maximized raising crops, usually need the mulch film stack of two kinds of difference in functionalitys is covered, cause input cost high, labour intensity is large, brings some inconvenience to agricultural production.

Summary of the invention

For overcoming above-mentioned technical problem, the invention provides a kind of ecological weeding expelling parasite with water saving, weeding, the anti-worm function of curing the disease disease-resistant functional membrane of economizing on water.

For realizing above-mentioned technical purpose, the present invention realizes by the following technical solutions: a kind of ecological weeding expelling parasite disease-resistant functional membrane of economizing on water is characterized in that: it is that the high-quality linear polyethylene of melt index 2 consists of that anti-aging master batch 6%-10%, the reflective master batch 5%-10% of titanium dioxide europium, grey color masterbatch 5%-10% and surplus are adopted in the upper strata; Lower floor adopts black masterbatch 5%-10%, linear polyethylene 90%-95% to consist of; Put respectively such as extrusion molding on the inside and outside two-layer extruder through high-speed stirred, the upper strata is the silver gray look, and lower floor is black.

The present invention has following beneficial effect: because it adopts the double-layer bi-color structure, the insulation water retention property is more excellent; The upper strata is silver gray, has preferably reflective, has increased the intensity of photosynthesis of crops, and plays the disease-resistant effect of deinsectization, and is particularly remarkable for the preventive and therapeutic effect of the insects such as aphid and white plant hopper; Lower floor is black, under cryogenic conditions, is of value to absorption solar energy and improves ground temperature, and can suppress to like the growth of light weeds.The present invention is applied on the crops, can economize on water more than 30%, increases production more than 20%, and can accomplish nuisanceless radical cure control of weeds damage by disease and insect, reduces pesticide pollution, has significant economic benefit and social benefit.

Embodiment

Embodiment one: the high-quality linear polyethylene 84% of melt index 2, anti-aging master batch 6%, the reflective master batch 5% of titanium dioxide europium, grey color masterbatch 5%, mix through high-speed stirred, black masterbatch with 5%, 95% linear polyethylene mix through high-speed stirred, above-mentioned two groups of raw materials are put into respectively extrusion molding on the inside and outside two-layer extruder, ecological weeding expelling parasite water-saving function film after the moulding is two layer composite structure, and the upper strata is silver gray, and lower floor is black, look circle is clearly demarcated, good toughness.

Embodiment two: with high-quality polyethylene 70%, anti-aging master batch 10%, the reflective master batch 10% of titanium dioxide europium, grey color masterbatch 10%, mix through high-speed stirred; Black masterbatch with 10%, 90% linear polyethylene mix through high-speed stirred, above-mentioned two groups of raw materials are put into respectively extrusion molding on the inside and outside two-layer extruder, ecological weeding expelling parasite water-saving function film after the moulding is two layer composite structure, the upper strata is silver gray, lower floor is black, look circle is clearly demarcated, good toughness.

Can be according to the width production of user's needs in the actual production process, thickness must not hang down the 0.006mm-0.008MM standard.The present invention is applied to the vegetable crops such as Chinese cabbage, celery, and the plantation of the melon or fruit type crops such as grape, watermelon, and water saving soil moisture conservation effect is remarkable, and output can improve more than 20%, and can prevent the sick worm of weeds, need not to use agricultural chemicals, has reduced production cost.

Claims

1. an ecological weeding expelling parasite disease-resistant functional membrane of economizing on water is characterized in that: it is that the high-quality linear polyethylene of melt index 2 consists of that anti-aging master batch 6%-10%, the reflective master batch 5%-10% of titanium dioxide europium, grey color masterbatch 5%-10% and surplus are adopted in the upper strata; Lower floor adopts black masterbatch 5%-10%, linear polyethylene 90%-95% to consist of; Put respectively such as extrusion molding on the inside and outside two-layer extruder through high-speed stirred, the upper strata is the silver gray look, and lower floor is black.
