Description
Technical field
The utility model is related to agriculture articles for use field, more particularly, to be a kind of highly-breathable weed removal mulch film.
Background technology
Weed removal mulch film covering mainly reaches weeding by completely cutting off the photosynthesis of sunlight, blocking weeds on the ground
Purpose.It is open and flat that sealant is formed behind ground, on the one hand, extraneous air since weed removal mulch film is black, air-locked film
Soil is cannot be introduced into, soil anoxic can be caused；On the other hand, a large amount of thermal energy of the film absorption of black and soil is passed to, and
Heat in soil can not be distributed by weed removal mulch film, especially in the summer high temperature time, easily lead to the temperature mistake in soil
It is high.Both situations have all seriously affected crop root and soil beneficial microorganism normal metabolic activity.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of highly-breathable weed removal mulch films.
To achieve the above object, the technical solution of the utility model is：A kind of highly-breathable weed removal mulch film, by up to
Include light-shielding film layer, wearing layer and air-permeable layer down.Latticed gas-permeable channels are equipped between the wearing layer and air-permeable layer, it is described
Gas channel extends to the outside of weed removal mulch film around, and cutting weed removal mulch film according to demand on the spot uses, and can ensure ventilative logical
Road is unimpeded.The air-permeable layer is provided with " ten " shape through-hole, and the through-hole is connected with gas-permeable channels.What " ten " shape through-hole was breathed freely
When bore edges air-permeable layer can open, increase the aperture of air hole, improve permeability.Light-shielding film layer can be used for obstructing weeds
Photosynthesis, realize the purpose of weeding.Through-hole can improve the gas permeability of weed removal mulch film with latticed gas-permeable channels.
Preferably, the wearing layer includes fiber portion and the degradation portion positioned at fiber portion both sides.The fiber portion is glass
Fiber Materials are made, and can increase wear-resisting property.The degradation portion includes polycaprolactone, polylactic acid and plant fiber.Weed removal mulch film
In use, the more Gong's soil coverings in weed removal mulch film both sides, capped position is made of degradable material.When weed removal mulch film recycles
It waits, degradation portion is broken down into fines left in the soil, it, will not contaminated land environment then gradually by soil fast degradation.
Preferably, the plant fiber includes one kind in cellulose acetate, cellulose propionate, acetylbutyrylcellulose,
Can accelerated degradation portion degradation.
Preferably, the air-permeable layer lower surface is coated with antiseptic, and antiseptic can prevent weed removal mulch film by infection such as moulds.
By using above-mentioned technical solution, the utility model has the beneficial effects that：The utility model discloses a kind of high
Gas weed removal mulch film, including light-shielding film layer, wearing layer and air-permeable layer.Light-shielding film layer can be used for obstructing the photosynthesis of weeds, real
The purpose of existing weeding.Through-hole can improve the gas permeability of weed removal mulch film with latticed gas-permeable channels.The drop that wearing layer both sides are equipped with
The recycling of weed removal mulch film can be convenient in solution portion.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is sectional view along AA in Fig. 1；
Fig. 3 is the portions B enlarged drawing in Fig. 2.
Main appended drawing reference explanation：（1, light-shielding film layer；2, wearing layer；21, fiber portion；22, degradation portion；3, air-permeable layer；
31, through-hole；32, antiseptic；4, gas-permeable channels）.
Specific implementation mode
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
The direction term being previously mentioned in the utility model, such as：Above and below, inside and outside etc., only it is reference explanation book attached drawing 1
Direction.Therefore, the direction term used is intended merely to illustrate, is not used for limiting the utility model.
As shown in Figure 1-Figure 3, a kind of highly-breathable weed removal mulch film of the utility model includes from top to bottom light-shielding film layer 1, resistance to
Grind layer 2 and air-permeable layer 3.
Latticed gas-permeable channels 4 are equipped between the wearing layer 2 and air-permeable layer 3, the gas-permeable channels 4 extend to around
The outside of weed removal mulch film cuts weed removal mulch film according to demand on the spot and uses, can ensure that gas-permeable channels 4 are unimpeded.The air-permeable layer 3
It is provided with " ten " shape through-hole 31, the through-hole 31 is connected with gas-permeable channels 4.Bore edges when " ten " shape through-hole 31 is breathed freely
Air-permeable layer 3 can open, increase air hole 31 aperture, improve permeability.Light-shielding film layer 1 can be used for obstructing the photosynthetic of weeds
Effect, realizes the purpose of weeding.Through-hole 31 can improve the gas permeability of weed removal mulch film with latticed gas-permeable channels 4.
The wearing layer 2 includes fiber portion 21 and the degradation portion 22 positioned at 21 both sides of fiber portion.The fiber portion 21 is glass
Glass Fiber Materials are made, and can increase wear-resisting property.The degradation portion 22 includes polycaprolactone, polylactic acid and plant fiber.Weeding
In use, the more Gong's soil coverings in weed removal mulch film both sides, capped position is made mulch of degradable material.When weed removal mulch film recycling
When, degradation portion 22 is broken down into fines left in the soil, it, will not contaminated land ring then gradually by soil fast degradation
Border.The plant fiber includes one kind in cellulose acetate, cellulose propionate, acetylbutyrylcellulose, can accelerated degradation portion
Degradation.
3 lower surface of the air-permeable layer is coated with antiseptic 32, and antiseptic 32 can prevent weed removal mulch film by infection such as moulds.
Above-described, the only preferred embodiment of the utility model cannot limit the range of this practicality implementation, all
It is equivalent change made according to the patent scope of the utility model and decoration, should all still falls within the range that the utility model is covered
It is interior.
