Abstract
The invention discloses a liquid fertilizer mulching film for increasing soil fertility for corn. The liquid fertilizer mulching film is prepared from the following raw materials in parts by weight: 49-51 parts of straw ash, 6-8 parts of coffee beans, 13-15 parts of modified starch solution, 14-16 parts of brown sugar, 3-5 parts of a composite microbial bacterial agent, 38-42 parts of lentinus edodes mushroom residues, 3-4 parts of polyethylene and a proper amount of water. Due to the addition of organic components such as the mushroom residues and the straw, the liquid fertilizer mulching film has a function of increasing the soil fertility, the added polyethylene is large in molecular weight, glue can be easily formed with water with high adhesion property, the adhesion property of the prepared mulching film to soil can be further improved, scattered sandy soil without structure can be connected to form an elastic stable body, and thus functions of heat preservation and soil moisture conservation can be achieved.
Description
Technical field
The present invention relates to a kind of agricultural film technical field, particularly a kind of corn liquid fertilizer mulch film of increasing soil fertility and preparation method thereof.
Background technology
Mulch film has the effects such as insulation, water conservation, frost protection to crop, the application of ground membrane technique improves and the output and the benefit that add farm crop greatly, but traditional mulch film is a kind of macromolecular compound of synthetic, degradable hardly in its natural state, after using, place to go is not comprehended and is caused very large pollution to edatope, affects crop root growth, and the mulch film of process is because of moist, damaged, also not reusable edible, can only as refuse reclamation, and work consuming is consuming time.
For this reason, the present inventor provides a kind of liquid fertilizer mulch film for corn, not only there is the water-retaining effect performance that common ground film is outstanding, have higher fertilizer simultaneously, material choice mostly is organic matter of easily degrading, simultaneously containing soil probiotics, by spraying the gel-like film formed in soil surface, provide protection is provided to corn planting, the use of collocation fertilizer, the dissolution rate of the nutrients such as Nitrogen, Phosphorus potassium can be improved, thus improve corn to the receptivity of fertilizer, its degraded product then forms the abundant humic acids of fertility, carbonic acid gas and water, not only pollution-free to soil, the physico-chemical property of soil can also be improved, as the substitute of common ground film, there is good application prospect.
