Abstract

The invention discloses a mulching film, and belongs to the field of accessory appliances for agriculture product cultivation. The mulching film comprises 55-80% of cotton, 1-5% of animal glue, 1-5% of vegetable glue, 5-15% of starch, 0.1-2% of enzymes, 0.1-2% of alachlor emulsifiable concentrate, 0.1-2% of metribuzin, 0.1-5% of soy protein adhesive, 1-10% of nutrient fertilizers and 5-15% of sea grass concentrated liquor. The mulching film has the advantages that the mulching film is good in heat-insulation effect, is degradable, is free of pollution to soil and has a weeding function.

Description

A kind of mulch film

 

Technical fieldThe present invention relates to a kind of mulch film, belong to agricultural-food cultivation auxiliary means field.

Background technologyMulch film, i.e. ground coating film, normally transparent or black PE film also has green, silver thin film, be used for ground and cover, to improve the soil moisture, keep soil moisture, keep Soil structure, prevent disease that insect invasion and attack crop and certain micro-organisms cause etc., the function of Promoting plant growth.Mulch film looks thin layer, but act on quite large, not only can improve ground temperature, water conservation, soil conservation, fertilizer conservation and improve fertilizer efficiency, and also have weed eradication, diseases prevention worm, take precautions against drought waterlogging-resistant, press down salt and keep a full stand of seedings, improve light and heat condition near the ground, make the multiple functions such as product hygiene.For those seedling of just being unearthed, has the short long effect that waits of mulch.For China three northern areas of China, the factor of the restriction agricultural development such as low temperature, poor ridge short of rain, arid, frostless season are short has very strong specific aim and suitability, for two season of plantation raising rice seedlings and the various crop cultivation on also played effect.Universal and application, be used for 40 multiple kinds of crops such as grain, cotton, oil, dish, melon and fruit, cigarette, sugar, medicine, fiber crops, tea, woods in 31, whole nation provinces, cities and autonomous regions, makes crop generally increase production 30%-50%, and increment 40%-60% is subjected to the welcome of vast farmers deeply.Mulching film planting covers a large amount of plastics films in the field, remains in after crop harvesting in soil, and hard degradation, along with the prolongation of the plastic film mulching cultivation time limit, the residual mulching film rate of recovery is low, and in soil, the residual film amount progressively increases, and soil has been caused pollution and harm.

Summary of the invention

In view of the defective that prior art exists, the purpose of this invention is to provide a kind of high insulating effect, degradable,, mulch film with weeding function pollution-free to the soil.

For achieving the above object, the technology used in the present invention solution is: a kind of mulch film is characterized in that its composition comprises: cotton, gelatin, vegetable jelly, starch, enzyme, alachlor missible oil, first grass piperazine, soy protein adhesive, nutrition fertilizer, sea grass concentrated solution.

Each component percentages is: 55%-80% cotton, 1%-5% gelatin, 1%-5% vegetable jelly, 5-15% starch, 0.1%-2% enzyme, 0.1%-2% alachlor missible oil, 0.1%-2% first grass piperazine, 0.1%-5% soy protein adhesive, 1%-10% nutrition fertilizer, 5%-15% sea grass concentrated solution.

Described mulch film is provided with breather hole.

A kind of mulch film, its beneficial effect is: temp effect is good, degradable, pollution-free to the soil, have a weeding function.

Embodiment
