Abstract
The utility model discloses a degradable double-layered mulching film which comprises an upper layer mulching film and a lower layer mulching film; the upper layer mulching film is a colorless heat-insulating mulching film, and the lower layer mulching film is a black weeding mulching film; the upper layer mulching film and the lower layer mulching film are entwined during production and winding; and the upper layer mulching film and the lower layer mulching film are both made of degradable materials. The service performance of the mulching film is improved so as to not only achieve the effect of insulating and preserving soil moisture but also weed to reduce the use of herbicide; and after use, the mulching film can automatically degrade to reduce white pollution in farmland.
Description
Technical field
The utility model relates to a kind of agricultural mulching, particularly a kind of degradable double mulch film.
Background technology
From the seventies mulch film quote so far, the soil moisture conservation effect that heats of mulch film is accepted, mulch film is widely used in agricultural tillage.The beginning of the eighties, weed removal mulch film was introduced into China, and weed removal mulch film has further solved again the weeding problem on the basis of original insulation soil moisture conservation effect, also be widely used subsequently.
But, along with the use of various mulch films with arbitrarily abandon, having caused a large amount of farmland " white pollution ", the recovery cost of mulch film is higher again, and time-consuming.The use of tradition mulch film does not meet the requirement of environmental protection really.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of not only practical but also has met the degradable double mulch film of environmental requirement, in order to reach the good result of use of mulch film and environment protecting.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of degradable double mulch film comprises upper strata mulch film and lower floor's mulch film; The upper strata mulch film is colourless Insulation Mulch Film, is used for the insulation in early stage; Lower floor's mulch film is Black Weeding Mulching Film, is used for the insulation in early stage and the weeding in later stage; Upper strata mulch film and lower floor's mulch film are intertwined when the production rolling.
As preferably, described upper strata mulch film and lower floor's mulch film all adopt degradation material to make.
As preferably, described upper strata mulch film and lower floor's mulch film all adopt oxidation-bio-degradable thin-film material to make.
The beneficial effects of the utility model are: the utility model has improved the serviceability of mulch film, not only plays the effect of insulation, soil moisture conservation, and all right weeding has reduced the use of classes of herbicides agricultural chemicals, and is automatically degradable after using, to reduce the farmland white pollution.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is structural representation of the present utility model.
Wherein, 1. upper strata mulch film, 2. lower floor's mulch film.
Embodiment
As shown in Figure 1, a kind of degradable double mulch film comprises upper strata mulch film 1 and lower floor's mulch film 2; Upper strata mulch film 1 is colourless Insulation Mulch Film, is used for the insulation in early stage; Lower floor's mulch film 2 is Black Weeding Mulching Film, is used for the insulation in early stage and the weeding in later stage; Upper and lower two-layer mulch film is intertwined when the production rolling.Described upper strata mulch film 1 and lower floor's mulch film 2 all adopt degradation material to make.
The upper strata mulch film be designed to colourless and degradation time shorter, be mainly used in early stage insulation, when ambient temperature was fit to plant growth, the colourless mulch film in upper strata began degraded; Lower floor's mulch film is designed to black and degradation time is longer, and play weeding effect for insulation, later stage early stage, and before and after the crop harvesting, lower floor's black film begins degraded.
During use, laminating machine or manually the degradable double mulch film is taped against in the ground, the upper strata mulch film is comparatively fast degraded, and lower floor's mulch film is degraded more slowly.
Handling characteristics of the present utility model is:
1, plant growth early stage, ambient temperature is lower, needs the mulch film temperature raising and maintaining, and double mulch film can play good insulation effect;
2, the plant growth middle and later periods, ambient temperature raises, and crop does not need the insulation effect of mulch film this moment yet, and the colourless mulch film in upper strata this moment begins degraded; The lower black mulch film still exists, and plays the effect of weeding, effectively reduces the use of weed killer herbicide;
3, before and after the crop harvesting, do not needed mulch film, this moment, lower floor's black film began degraded;
4, can be according to the different requirements set of the Different Crop different degraded fate of degradable double mulch film, in the degradation process, carry out first light/thermal oxidative degradation, molecular weight is dropped to oligomer below 10,000, then begin biological degradation, finally be decomposed into carbonic acid gas, water and humus, both had good serviceability, solved again traditional mulch film and used the white pollution problems that causes.
More than the utility model embodiment is described in detail, used embodiment herein the utility model set forth, the explanation of above embodiment just is used for helping to understand product of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
