Abstract

The invention discloses a kind of ecological weeding expelling parasite water-saving function film, upper strata employing anti-aging master batch 6%-10%, titanium dioxide europium reflective master batch 5%-10%, grey color masterbatch 5%-10% and surplus are that the high-quality linear polyethylene of melt index 2 is formed; Lower floor adopts black masterbatch 5%-10%, linear polyethylene 90%-95% is formed; Extrusion molding on inside and outside two-layer extruder is put into respectively through high-speed stirred.It adopts double-layer bi-color structure, and can economize on water more than 30%-35%, volume increase more than 20%-30%, accomplishes the sick worm of nuisanceless radical cure control of weeds, has significant economic benefit and social benefit.

Description

Ecological weeding expelling parasite is economized on water disease-resistant functional membrane

Technical field

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

Background technology

Traditional mulch film is white clear film normally, for covered ground, there is raising soil temperature, keep soil moisture, maintain soil structure, prevent the disease etc. that pest attacks crop and certain micro-organisms cause, the functions such as Promoting plant growth, it achieves significant economic benefit in application agriculturally.

Along with agrotechnical development, also in succession there is the mulch film with specific function, prevent weeds as having, improve the black mulch film of temperature function, the grey reflective membrane etc. there is expelling parasite, preventing disease from occurring, this kind of coloured functional mulch film is generally individual layer monochrome, also just make often kind of mulch film function more single, in agricultural production process, in order to the advantageously grow environment of maximized raising crops, the superposition of the mulch film of two kinds of difference in functionalitys is usually needed to cover, 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 have water saving, weeding, anti-worm function of curing the disease ecological weeding expelling parasite to economize on water disease-resistant functional membrane.

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

The present invention has following beneficial effect: because it adopts double-layer bi-color structure, and insulation water retention property is more excellent; Upper strata is silver gray, has good reflective, adds the intensity of photosynthesis of crops, and plays the disease-resistant effect of deinsectization, and the preventive and therapeutic effect particularly for the insect such as aphid and white plant hopper is remarkable; Lower floor is black, under cryogenic, is of value to and absorbs solar energy to improve ground temperature, and can suppress the growth liking light weeds.The present invention is applied on crops, can economize on water more than 30%, volume increase 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 of titanium dioxide europium 5%, grey color masterbatch 5%, mix through high-speed stirred, the black masterbatch of 5%, the linear polyethylene of 95% are mixed through high-speed stirred, above-mentioned two groups of raw materials are put into respectively extrusion molding on inside and outside two-layer extruder, ecological weeding expelling parasite water-saving function film after shaping is two layer composite structure, and upper strata is silver gray, and lower floor is black, look circle is clearly demarcated, good toughness.

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

The width that can need according to user in actual production process is produced, and thickness must not low 0.006mm-0.008MM standard.The present invention is applied to the vegetable crop such as Chinese cabbage, celery, and the plantation of the melon or fruit type crops such as grape, watermelon, water saving soil moisture conservation Be very effective, and output can improve more than 20%, and can prevent the sick worm of weeds, without the need to using agricultural chemicals, reduces production cost.

Claims

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