Abstract
The utility model discloses a kind of positive and negative dichromatism agricultural mulching, described positive and negative dichromatism agricultural mulching is three-decker, outside is the first color ground rete and the second color ground rete, and intermediate layer is hot melt adhesive layer, and the inner surface of the first color ground rete and the second color ground rete has reinforcing shrinkage pool.The utility model provides a kind of described positive and negative dichromatism agricultural mulching, by hot melt adhesive layer, the first color ground rete and the second color ground rete are linked together, both the kind selected of mulch film color had been added, enrich its result of use, wear glue hole by setting simultaneously and reinforce fine hair, improve ground film strength.
Description
Technical field
The utility model relates to a kind of mulch film, especially a kind of positive and negative dichromatism agricultural mulching.
Background technology
Agricultural mulching refers to and is directly covered in cultivating bed or subaerial slim plastic sheeting for farm use.In recent years, various coloured plastic sheeting for farm use goes on the market one after another, because the absorption of plastic sheeting for farm use to spectrum of different colours is different with reflexive property, also different on the impact of crop growth and weeds, damage by disease and insect, ground temperature.Modern mulch film developed into various coloured mulch film by common ground film and weeding, insect protected etc. multi-functional mulching specially used.Therefore in use for the feature of different crops and planting season, the plastic sheeting for farm use of different colours to be selected.Such as light transmittance is higher than white plastic sheeting for farm use under low-light condition for blue mulch film, and light transmittance is lower than white plastic sheeting for farm use under high light conditions, and heat-insulating property is good.Be applicable to seedling, nursery, not only mature seedling planting percent is high, and seedling is sturdy, and the alternaria of brassicaceous vegetable can be suppressed to grow, and has the significantly volume increase effect of guaranteeing the quality.Be highly suitable for rice breeding, also can be used for vegetables, cotton, peanut, strawberry, potatoes and other crops culture underglass.And green plastic sheeting for farm use can make green light according to increasing, weed growth being controlled, preferably management of weeds, improving output.Be usually used in the cultivation covering the vegetables such as Kidney bean, eggplant, pimento, melon, strawberry and other economic crops.But existing coloured agricultural mulching is mostly monochromatic mulch film, make its result of use comparatively single, and there is the low defect of intensity, the requirement of scientic planting cannot be met.
Summary of the invention
The utility model, for solving prior art above shortcomings, provides a kind of positive and negative dichromatism agricultural mulching.
The utility model is realized by following proposal:
A kind of positive and negative dichromatism agricultural mulching, for three-decker, outside is the first color ground rete and the second color ground rete, intermediate layer is hot melt adhesive layer, the first color ground rete, and the inner surface of the second color ground rete has reinforcing shrinkage pool, make the colloidal sol of hot melt adhesive layer pass through reinforcing shrinkage pool and reinforce the connection with the first color ground rete and the second color ground rete, prevent hot melt adhesive layer from occurring horizontal sliding, strengthen this ground film strength further, prevent from breaking.
The inner surface of the first color ground rete and the second color ground rete is provided with reinforcing fine hair, and making to reinforce fine hair can be engaged in hot melt adhesive layer, and then strengthens this ground film strength.
The thickness of described hot melt adhesive layer is 15-25 μm.
The thickness of described first color ground rete and the second color ground rete is 30-40 μm.
The beneficial effects of the utility model are: by hot melt adhesive layer, the first color ground rete and the second color ground rete are linked together, both the kind selected of mulch film color had been added, enrich its result of use, worn glue hole by setting simultaneously and reinforce fine hair, improve ground film strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high strength mulch film of the utility model.
In figure: 1 is the first color ground rete, and 2 is the second color ground rete, and 3 is hot melt adhesive layer, and 4 for reinforcing shrinkage pool, and 5 for reinforcing fine hair.
Embodiment
Below in conjunction with Fig. 1, the utility model is further illustrated:
Embodiment one
A kind of positive and negative dichromatism agricultural mulching is three-decker, and outside is the first color ground rete 1 and the second color ground rete 3, and intermediate layer is hot melt adhesive layer 2.PUR is bonded together the first color ground rete 1 and the second color ground rete 3, obtains the mulch film of positive and negative dichromatism; By the combination of different colours of the first color ground rete 1 and the second color ground rete 3, the positive and negative dichromatism agricultural mulching of multiple different colours can be obtained.
The inner surface of the first color ground rete 1 and the second color ground rete 3 has reinforces shrinkage pool 4, this reinforcing shrinkage pool 4 is exactly in fact blind hole structure, make the colloidal sol of hot melt adhesive layer by reinforcing the connection of shrinkage pool 4 and reinforcing and the first color ground rete 1 and the second color ground rete 3, prevent hot melt adhesive layer from occurring horizontal sliding, this ground film strength of further reinforcement, prevents from breaking.
The inner surface of the first color ground rete 1 and the second color ground rete 3 is provided with reinforces fine hair 5, and making to reinforce fine hair 5 can be engaged in hot melt adhesive layer, and then strengthens this ground film strength.
