Abstract
The utility model relates to an environment-friendly weeding and degradable plastic film which comprises a light transmitting part (1) in the middle and light blocking parts (2) on two sides; the plastic film is 0.005-0.02 mm in thickness and 35-800 cm in width; the plastic film is formed by evenly matching linear low density polyethylene LLDPE7042 and degradable raw materials (3); the light blocking parts (2) are also added with black masterbatch or green masterbatch used as the weeding raw material, so as to prevent the light from being transmitted or filter the light that is beneficial to the growth of plants; and the light transmitting part (1) of the plastic film is 10-30 cm in width. As the light transmitting part of the plastic film is covered at the crop planting position, the effect for transplanting crops, various vegetables, tobaccos and cotton is good, and for the direct seeding crops such as corn and beans, the hole punching and dot seeding after land film mulching are favorable for seedling emergence; and when being used for sugarcane cultivation, the plastic film is tightly attached to the soil surface, so as to be favorable for emergence of young seedlings.
Description
Technical field
The utility model relates to polymeric material field and environmental protection type agricultural technical field, especially a kind of environmentally friendly weeding degradable mulch film.
Background technology
Plastic film mulching cultivation has increased substantially crop yield and quality, the external ground film thickness general thickness of producing is 0.011-0.015mm, for saving the plastic mulching cost, China's mulch film thickness calibration is in about 0.008mm, but the long-term use of mocromembrane has caused the significantly underproduction of a large amount of residual and crops.According to research reports, the residual wheat yield 9%-26% that causes of mulch film, corn underproduction 11%-23%, cotton underproduction 10%-15%, soybean underproduction 5.5%-9.0%, vegetables underproduction 14.6%-59.2%.In production in the urgent need to the mulch film of environment-friendly type.In the production process of crops, the use of weed killer herbicide has significantly improved agricultural economy efficient.Along with the dependence of agricultural production weed killer herbicide constantly increases, weed killer herbicide constantly increases in the residual quantity in farmland, and soil environment has been caused destruction in various degree, needs environmentally friendly weeding technology in production.
In the situation that the agricultural workforce is day by day in short supply, the conventional agriculture of intensive cultivation is difficult to continue, and agricultural mechanization, disposable agrotechnique will be the trend of the future of agriculture technical development.And the mulch film with degradation function and Physical weeding will be that the elimination mulch film is residual, reduce agricultural production and move back weed killer herbicide dependence, a kind of effective ways of labor savings.
Degradative plastic film has had a large amount of research and application, and main Types has photodegradation film, Biodegradable mulch, light/life degradative plastic film, and its pluses and minuses are respectively arranged.The photodegradation film speed difference of degrading under Different climate is larger, and the Biodegradable mulch cost is higher.Use at present the weed removal mulch film that contains weed killer herbicide can bring the residual of weed killer herbicide, and bring growth in various degree to poison to crop.
Summary of the invention
The utility model provides a kind of environmentally friendly weeding degradable mulch film, and it is a kind of environmentally friendly degradative plastic film that relies on the physical method weeding, can effectively solve the problem of above-mentioned existence.
The utility model is achieved through the following technical solutions its purpose:
A kind of environmentally friendly weeding degradable mulch film is characterized in that, mulch film is made of the light transmission part (1) of centre and the light-blocking part (2) of both sides; Ground film thickness 0.005-0.02mm, width 35-800cm.
As the preferred technical scheme of the utility model:
Described mulch film is that LLDPE LLDPE7042 formed with even cooperation of degraded raw material (3); Described degraded raw material (3) is manganese stearate or cerium stearate light heat sensitizer.
Described light-blocking part (2) also adds as the black agglomerate of weeding raw material or green master batch, to stop light to pass through or to filter the effective light of plant growth.
Described mulch film light transmission part (1) width is 10-30cm.
This mulch film that the utility model provides is recommended in spring, summer, autumn and covers and use, and the light transmission part of film covers the crop-planting place.Good for transplanting the various vegetables of crop, tobacco, cotton texts.Seed sowing crop such as corn, beans etc., after the soil overlay film, the punching program request is conducive to emerge; When being used for cultivation of sugar cane, plastic mulching should be close to the soil table, is conducive to seedling puncture rupture of membranes and is unearthed.
Description of drawings
Fig. 1 is external structure schematic diagram of the present utility model;
Fig. 2 is inner degraded feed distribution schematic diagram of the present utility model.
Number in the figure is respectively: 1. light transmission part; 2. black or green light-blocking part; 3. the degraded raw material that distributes.
Embodiment
Light transmission part 1: add micro liquid paraffin in graininess LLDPE LLDPE 7042, and add light heat sensitizer cerium stearate and manganese stearate as degraded raw material 3, utilize the abundant mixing of screw batch mixer, by the inflation film manufacturing machine production of two extruders.
Light-blocking part 2: add black agglomerate and micro liquid paraffin in graininess LLDPE LLDPE 7042, after preliminary the mixing, add light heat sensitizer cerium stearate and manganese stearate as degraded raw material 3, utilize the abundant mixing of screw batch mixer, by the inflation film manufacturing machine production of two extruders.
Light transmission part and light-blocking part are connected as one, with mulch film rolling, packing.In the low latitudes zone use of height above sea level 800-1400m, effectively the cover time is 90-110 days, and compared with the control, the weeds control rate is more than 95%.
Claims (2)
1. an environmentally friendly weeding degradable mulch film, is characterized in that, mulch film is made of the light transmission part (1) of centre and the light-blocking part (2) of both sides; Ground film thickness 0.005-0.02mm, width 35-800cm.
2. environmentally friendly weeding degradable mulch film according to claim 1, is characterized in that, described mulch film light transmission part (1) width is 10-30cm.
