Abstract
The invention relates to a special mulching film for ginger, comprising colorless farm-oriented polyethylene. The raw materials comprise the following ingredients: 1-10 wt% of green color masterbatch, 5-20 wt% of antidrop thermal masterbatch, and 75-94 wt% of linear low density polyethylene. The prepared special mulching film for ginger has the thickness of 0.006-0.02 mm and the transmissivity of 40-85 wt%, and the transmittance spectra green light ratio is increased by 5-15 over general mulching film. Using the special mulching film for ginger can promote the growth of ginger, and improve the yield and quality of ginger. The invention has a good application prospect.
Description
One, technical field
It is mulching specially used to the present invention relates to a kind of ginger, belongs to the agricultural plastic film product.
Two, background technology
The agripast mulch film of producing and using though specification (width, thickness) has broad variety, is not still produced the mulch film that is suitable for a certain crop special use according to crop to illumination, temperature, humidity demand characteristics at present.China is ginger big producing country, at the demand characteristics of ginger to temperature, illumination, humidity, is badly in need of a kind of special-purpose plastic film of ginger cultivation that is suitable for of development.
Three, summary of the invention
The purpose of this invention is to provide the special-purpose plastic film of a kind of ginger cultivation, can realize environment coordinated regulations such as temperature, illumination, humidity, both reduce the field operation steps, reduce labour intensity, help again promoting ginger to grow, improve the ginger yield and quality.
A kind of ginger is mulching specially used, be made up of by weight percentage following raw materials according: green colour batch 1%-10%, nothing drip insulation masterbatch 5%-20% and linear low density polyethylene (LLDPE) 75%-94% forms, its each material composition by weight percentage, with its mixed milling blowing film forming.
Described nothing drip the insulation masterbatch form by weight percentage by following composition: LLDPE powder 90%-96%, dripless agent LA-2 1%-5% and heat preserving agent talcum powder 3%-6%.
Technical scheme of the present invention is: at the problem of still not having at present ginger special plastic mulch film, according to the light requirement characteristics of ginger to temperature, illumination and humidity, by selecting rational colour batch for use, not having the insulation of dripping masterbatch, scientific matching, change transmittance, transmitted spectrum composition and insulation, the soil moisture conservation performance of plastics film, grow to environment requirement to adapt to ginger.
Finished product ginger prepared in accordance with the present invention is mulching specially used to have that transmitted spectrum green glow composition increases, transmittance is moderate, early stage good heat insulation, middle and later periods heat up and wait function slowly, very help growing of ginger, improve ginger output, and can realize a film dual-purpose (heat, shading, soil moisture conservation), reduce the field operation steps, reduce investment outlay, increase the ginger productivity effect.
Four, description of drawings
Fig. 1, the mulching specially used processing process figure of ginger
Among the figure: 1, linear low density polyethylene (LLDPE), 2, do not have to drip an insulation masterbatch, 3, green colour batch, 4, dripless agent, 5, heat preserving agent, 6, mix, 7, add hot milling, 8, the blowing finished product.
Five, embodiment
The present invention be research ginger to temperature, illumination, humidity demand characteristics basis on, at still there not being mulching specially used this present situation of ginger at present, by adding suitable colour batch, through scientific and reasonable formula development.The product the key technical indexes is: transmittance 40%-85%, transmitted spectrum green glow ratio increases 5%-15% than common ground film, film thickness 0.006-0.02mm.
Below in conjunction with accompanying drawing in detail the course of processing and processing requirement are described in detail.
At first preparation does not have the insulation of dripping masterbatch (2), and each composition weight percent is: LLDPE powder 90%-96%(1), dripless agent LA-2 1%-5%(4), heat preserving agent talcum powder 3%-6%(5).With the mixing wire drawing cooling and dicing of extruding of above each raw material thorough mixing even heating, promptly become the alleged nothing of the present invention and drip the insulation masterbatch.The nothing that will account for this product weight 5%-20% is then dripped insulation masterbatch (2), the green colour batch (3) of 1%-10%, the LLDPE(1 of 75%-94%) mixes (6), mixed uniformly raw material being added hot milling (7) extrudes again, be blow molded to finished product (8) warehouse-in, above complete processing is source mill's common process technology.
The ginger film-mulching cultivation, generally 3, ginger in April timely overlay film after planting, overlay film can adopt arch to cover or close proximity to ground covers, to 6, take off film July when ginger is earthed up for the first time.Utilize this product to carry out the ginger film-mulching cultivation, generally increase production more than 10% than normal transparent film.This product processes is simple, and it is convenient to use, and is suitable for the ginger plastic film mulching cultivation, and good popularizing application prospect is arranged.
