Abstract
The utility model relates to the technical field of chemical industry and biological materials, in particular to an insecticidal mulching film capable of being degraded. A biodegradable mulching film is adopted as a carrier film, and one surface of the carrier film is compounded with an insecticidal surface layer, so the carrier film can become the insecticidal mulching film capable of being degraded. The using method is that one surface of the mulching film compounded with the insecticidal surface layer is placed downwards and is covered on the surface of earth. The insecticidal mulching film capable of being degraded has the beneficial effects that the balance problem of water resistance and hydrophilia is solved, and the surface can be directly compounded with preparations of oily, milky and/or wetting powder; under the condition as the mulching film, an insecticide can be effectively slowly released, and the insecticidal effect is good; the mulching film can adapt the climate and soil environment of various regions and meets the requirements of heat preservation and preservation of soil moisture of different crops, and the mulching film can be automatically degraded and does not have pollution after the insecticidal function is completed; the use is convenient, and the cost is relatively low; and the agricultural production efficiency is obviously increased.
Description
Technical field
The utility model relates to chemical industry and technical field of biological materials, relates to the preparation that has functional Biodegradable mulch, specifically, is a kind of desinsection mulch film that can degrade.
Background technology
It is the farm work that must carry out that crops are carried out desinsection, weeding and fertilising.These farm works all can have regular hour and condition restriction, as the restriction of season, temperature and rainwater.In the common ground film covering phase, be subjected to the restriction of insecticide lasting effect, can't incubate the insect of phase and effectively kill being in ovum in the agricultural land soil.If can be on Biodegradable mulch the direct function of composite insecticidal, just can avoid the strong volatilization under rainwash and sunshine, can realize the slow release of insecticide, make its efficient obtain prolongation, kill pests in ovum is incubated the phase.Desinsection mulch film with this function can promote the efficient of agricultural production undoubtedly effectively.
But, because present mulch film is polyethylene ground film, can't compound oiliness on its surface, milkiness and/or Wettable Powder preparation, therefore, it can not be compound with Insecticides (tech) ﹠ Herbicides (tech) and nutrient solution etc.And with the functional mulching film of Biodegradable mulch as base material, its manufacturing technology difficulty is big, the cost height, so, on market, almost there is not ripe biodegradable desinsection mulch film at present with single or complex function.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can adapt to various places weather and soil environment, need not the desinsection mulch film that reclaims, can degrade.
The utility model is to have contained alloy master batch, 7042(LDPE having adopted), make on the basis of the Biodegradable mulch of 1F7B (LDPE), because this Biodegradable mulch has solved the problem of resistance to water and hydrophilic balance, therefore, the direct compound oiliness of its surface energy, milkiness and Wettable Powder material, therefore, can make the desinsection mulch film that to degrade.
For realizing above purpose, the technical scheme that the utility model is taked is:
A kind of desinsection mulch film that can degrade adopts Biodegradable mulch as carrier film, it is characterized in that, is compounded with one deck desinsection top layer in the one side of carrier film, makes it to become the desinsection mulch film that can degrade.
The using method of a kind of desinsection mulch film that can degrade of the utility model is: with mulch film be compounded with one of desinsection top layer face down placement, cover the face of land and get final product.
The good effect of a kind of desinsection mulch film that can degrade of the utility model is:
(1) avoided strong volatilization under rain drop erosion and the sunlight direct projection, made insecticide obtain slowly discharging most effectively, made the better effects if of its desinsection;
(2) can adapt to various places weather and soil environment, satisfy the requirement of different crops insulation soil moisture conservation phase, after insecticidal action was finished, mulch film was degraded automatically, noresidue, pollution-free, need not to reclaim;
(4) easy to use, cost is lower, can use on a large scale, and agricultural production efficiency is significantly improved.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of desinsection mulch film that can degrade of the utility model;
Accompanying drawing 2 is the detection curve figure of a kind of desinsection mulch film degradation effect that can degrade of the utility model;
Label among the figure is respectively: 1, Biodegradable mulch; 2, desinsection top layer.
Embodiment
Referring to accompanying drawing 1.A kind of desinsection mulch film that can degrade adopts Biodegradable mulch 1 as carrier film, and the one side spraying insecticide in carrier film forms one deck desinsection top layer 2, both the compound desinsection mulch films that can degrade that become.In concrete enforcement of the present utility model, can directly buy Biodegradable mulch 1 and carry out the production of desinsection mulch film, the product that Biodegradable mulch 1 can adopt Changzhou hundred niche biomaterial Science and Technology Ltd.s to produce, insecticide can adopt poly-upright " the poly-upright letter " biological insecticides of believing that biotechnology Co., Ltd produces in Chongqing; Utilize prior art and technology to finish the spraying of insecticide on Biodegradable mulch 1, will carry out rolling behind the insecticide oven dry formation one deck desinsection top layer 2 that be sprayed on the Biodegradable mulch 1.
Country synthetic resin and plastic quality supervision and inspection center are that 63 ℃, intensity are the detection of having carried out degradation effect under the condition of 1000 uW/C ㎡ to the submitted sample of a kind of desinsection mulch film that can degrade of the utility model in the ultraviolet irradiation temperature.That detects the results are shown in following table:
Degradation effect curve map by its making is seen accompanying drawing 2.
