Compared with prior art, provided by the utility model point of band difference degraded color matching agricultural mulching, significantly improve biodegradable controllability, and met crop different growth stage to temperature, moisture, ventilative etc. needs by the asynchronous degraded of subregion, there is dynamic, multidirectional regulatory function.In addition, some part of provided by the utility model point of band difference degraded color matching agricultural mulching can be degraded, and convenient recovery, reduces environmental pollution.
Brief description of the drawings
The schematic diagram of Fig. 1 the utility model specific embodiment one.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of point of band difference degraded color matching agricultural mulching, it is by three band alternate compositions, and wherein, the band of both sides is identical, and different from middle band.Its production technology is identical with traditional mulch film.
Specific embodiment one
As shown in Figure 1, a kind of point of band difference degraded color matching agricultural mulching, centre is the two degraded of controllable light temperature band, both sides are polyethylene band.Utilize three road co-extrusions, wherein first and third passage is blow moulded polyethyene passage, and center-aisle is controllable part biodegradation material blowing passage.By weight, in first and third passage, 100 parts of polyethylene; In center-aisle, polyethylene 95-99 part, light temperature mother raw material degradable 1-5 part.In each passage, each raw material are stirred and make masterbatch with extrusion granulating machine afterwards, then according to conventional blow molding process coupling coextrusion blow to finished product.
Taking peanut ridging plastic-film-covered cultivation as example, generally overlay film in time after peanut seeding at the beginning of by the end of April to 5 month.Utilize agricultural mulching of the present invention, enter after July rainfall season, the block degraded of the two degraded of middle controllable light temperature band starting point, can reduce the impact of high temperature on root growth, significantly improve root system moisture around, be beneficial to root system and keep higher vigor and long active period, than common ground film increase yield significantly, quality is also obviously improved.
As the further improvement of embodiment mono-, intermediate strap width be film wide 1/10 to 1/2.
Specific embodiment two
A kind of point of band difference degraded color matching agricultural mulching, centre is controllable part biological degradation band, both sides are Dyeing polyethylene band.Utilize three road co-extrusions, wherein first and third passage is blow moulded polyethyene passage, and center-aisle is controllable full-biodegradable material blowing passage.In first and third passage, by weight, polyvinyl resin masterbatch 90-99 part, Masterbatch 1-10 part.In center-aisle, by weight, polyethylene 75-95 part, complete biodegradable masterbatch 5-25 part, bulking agent 1-5 part.Stir and make masterbatch with extrusion granulating machine afterwards.Then mate coextrusion blow to finished product according to conventional blow molding process.Wherein, Masterbatch can require to select commercially available black, red, yellow, purple, blue or green master batch according to crop.
Plant the crop growing breeding time early spring as peanut, cotton etc., crop-planting or field planting are at the colourless band of centre, quick heating, emerge early and together, when later stage, temperature was high, root system is grown again under the more stable coloured mulch film of ground temperature, can alleviate the adverse effect of high temperature to root system, and simultaneously wider coloured mulch film can shading press down grass.Enter after July rainfall season, the block degraded of middle controllable part biological degradation band starting point, can reduce the impact of high temperature on root growth, significantly improve root system moisture around, be beneficial to root system and keep higher vigor and long active period, than common ground film increase yield significantly, quality is also obviously improved.
The agricultural color matching mulch film of middle part controllable part biological degradation, not only can improve the infiltration capacity of crop later stage precipitation to soil, reduce root system environment temperature, delay Senescence of Root System process, and coloured moiety can change light quality, reduce high light to root system or piece root, the harmful effect of tuber crops or the generation that alleviates damage by disease and insect, can reduce the expense such as agricultural chemicals or weed killer herbicide, thereby significantly improve crop yield and improve quality, safe and efficient.
As the further improvement of embodiment bis-, intermediate strap width be film wide 1/10 to 1/2.
Specific embodiment three
A kind of point of band difference degraded color matching agricultural mulching, centre is black polyethylene band, both sides are complete biodegradable band.Utilize three road co-extrusions, wherein first and third passage is controllable full-biodegradable material blowing passage, and center-aisle is blow moulded polyethyene passage.In first and third passage, by weight, biodegradation material 95-99 part, bulking agent 1-5 part.In center-aisle, by weight, polyethylene 95-99 part, black agglomerate 1-5 part.Stir and make masterbatch with extrusion granulating machine afterwards.Then mate coextrusion blow to finished product according to conventional blow molding process.
To transplant tobacco as example to the first tenday period of a month in May by the end of April.Utilize agricultural mulching of the present invention, reduce the high temperature seedling rate of burning, improve into rate in active and strong sprout.Enter after July rainfall season, the biodegradable band in both sides becomes band or the block degraded of point, can reduce the impact of high temperature on root growth, significantly improve root system moisture around, be beneficial to root system and keep higher vigor and long active period, than common ground film increase yield significantly, quality is also obviously improved.When results, the middle recyclable recycling of long-life band, remains in the part fully biodegradable in soil.
Meanwhile, agricultural mulching of the present invention is also applicable to various other crops transplantings that need to improve the mulch film rate of recovery, reduce environmental pollution.
As the further improvement of embodiment tri-, intermediate strap width be film wide 1/10 to 1/2.
In sum, compared with prior art, provided by the utility model point of band difference degraded color matching agricultural mulching, significantly improve biodegradable controllability, and meet crop different growth stage to temperature, moisture, ventilative etc. needs by the asynchronous degraded of subregion, there is dynamic, multidirectional regulatory function.In addition, some part of provided by the utility model point of band difference degraded color matching agricultural mulching can be degraded, and convenient recovery, reduces environmental pollution.
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; If do not depart from spirit and scope of the present utility model, the utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
