Abstract
The invention provides an intelligent microporous temperature-control air-permeable mulching film which comprises non-woven fabric, an elongated channel on the non-woven fabric, an intelligent moisture regulator inlayed in the center of the channel and suckers arranged at the bottom of the non-woven fabric at intervals. The mulching film is thin and light, is convenient for transportation and construction, is easy to generalize, has the advantages of low price and strong self-adaption to an underlying surface in use, can improve high-moisture penetration, reduce moisture evaporation and effectively reduce the production and management cost in the field of agriculture, forestry, and the like and is beneficial to the high-efficiency and economical utilization of water resource. The intelligent microporous temperature-control air-permeable mulching film is mainly used in agriculture, forestry and other fields.
Description
Technical field
The present invention relates to a kind of mulch film, particularly relate to the ventilative mulch film of a kind of intelligent micropore temperature control.
Background technology
Cladding material has the protection soil structure, resists water erosion wind erosion, the soil moisture conservation retaining, regulates soil temperature, suppresses effect such as weed growth, has been widely used in every field such as agricultural, gardens at present.Wherein, the plastic film ground covering technique is used comparatively extensive, but because the film covering can cause soil temperature higher, and tackled rainfall infiltration, be unfavorable for that effective storage of soil moisture utilizes with efficient.In addition, degradable cladding material has appearred in the world in recent years, as water soluble film, gauze, fiber crops net etc.Japan Patent JP8338025-A is by forming permeable formation with boring or cutting mode on the jute felt, for the plant base material of bottom surface provides support.Though this product can improve moisture and infiltrate ability, do not possess the function of controlling plant base material water evaporates, the cost height of jute net itself, stronger hardness is not easy to closely attach with the underlying surface base material, need increase fixation in addition.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, provides that a kind of cost is low, construction is simple, and can realize mulch film and the organic absorption of underlying surface, realizes that moisture infiltrates and the intelligent micropore temperature control that the evaporates intelligent control mulch film of breathing freely.
The ventilative mulch film of intelligent micropore temperature control of the present invention comprises nonwoven, is positioned at the strip duct on the nonwoven, is embedded in the moisture intelligent regulator at center, duct, and the alternate sucker that is arranged on the nonwoven bottom surface.Wherein, nonwoven thickness is 40～60g/m
2, permeation rate is 5～8mm/s; Orifice throat length is 5～30mm, and width is 0.1～100 μ m, and the duct is 5～100mm along the spacing of nonwoven width alternately, is 10～50mm along the spacing of nonwoven length direction; In the moisture intelligent regulator is spherical swellable polymer body, and its diameter is 0.5～105 μ m, and water-swellable rate and dehydration shrinkage factor are 1～100 times; Sucker is by the macromolecule sucker, and the water-solubility membrane that is wrapped in outside the macromolecule sucker is formed its diameter 5～10mm, the intrinsic viscosity 〉=1500ml/g of macromolecule sucker, sucker is 50～100mm along the spacing of nonwoven width, is 10～50mm along the spacing of nonwoven length direction.
The operation principle of the ventilative mulch film of intelligent micropore temperature control of the present invention is directly it to be covered in soil or artificial substratum surface and fixing during use.In rainfall or manually water under the water condition, mulch film moisture abundance, opening of the channel is opened in the imbibition of moisture intelligent regulator, and moisture infiltrates soil or the artificial substratum from the duct, supplies with the moisture of plant growing; Than under the drying condition, the dehydration of moisture intelligent regulator is shunk at environment, and opening of the channel is closed naturally, the soil under the controlled mulch film or the water evaporates of artificial substratum, and play ventilative insulation effect.In addition, in rainfall or manually water under the water condition, after the water-solubility membrane on the sucker was met water-soluble separating, sucker produced stronger cohesive force, makes mulch film and soil surface adsorbed close, prevents that mulch film from being blown off by wind.
The advantage of the ventilative mulch film of intelligent micropore temperature control of the present invention is: one, and thin thickness, in light weight, can efficiently transport, and construction, convenient in carrying, be beneficial to commercialization and promote; Its two, manufacture craft is simple, and is cheap, is beneficial to the construction and the popularization of production line; Its three, with the underlying surface adsorbed close, prevent to be blown off by wind; Its four, can regulate the duct by the moisture intelligent regulator and open and close, improve moisture and infiltrate and reduce water evaporates, increase effective water-holding capacity of soil or artificial substratum; Its five, effectively reduce the water management cost in the management of agricultural, gardens and other industry production, realized that water resource is efficient, the economized utilization.
