Description
Technical field：The present invention relates to agricultural mulching technical field, it is specially a kind of with temperature raising, preserves soil moisture, weeding and increasing
Multi-functional liquid agricultural mulch film of fertilizer and preparation method thereof.
Background technology：Plastic film mulching cultivation is the important means in agricultural production, and farming can be met using covering with ground sheeting
Thing heats, preserves soil moisture, keep fertility the need for, be mainly used in the north, arid, the getting up early covering of cold district crop and windproof solid
Sand, with promotion crop yield, ahead of time improving quality, the function such as maturation.
The mulch film of agricultural application at present has plastic film and liquid-state mulch film, and plastic film is on the high side, takes during using operating cost
Power, is more importantly difficult to degraded and causes white pollution.And the film forming and caking property that existing liquid-state mulch film product has are relatively low,
Spray has cracking after earth's surface, the phenomenon such as ventilated, and humidification, soil moisture conservation effect is poor；Some process rain drop erosiones, Premature disintegration,
Demoulding, does not have due effect；Some products contain anion or nonionic surfactant, and film-formation result is poor, it is also possible to
Cause soil pollution.
The content of the invention：
Goal of the invention：In place of the present invention is for the shortcoming and defect of existing product, it is proposed that a kind of multi-functional liquid
Film, film forming is high, easily degraded, while with heating, soil moisture conservation, weeding, the function of getting fat.
Technical scheme：The present invention is implemented by the following technical programs：

The grand one or more by pyrazosulfuron, double second sulphurs in grand are replaced with arbitrary proportion.
Advantage and effect：
1. mulch film is integrated with herbicide, fertilizer, with multi-functional weeding and fertilization effect.
2. cost is low, it is easy to promote.
3. seedling can directly rupture of membranes grow, save artificial.
4. being easy to degraded, prevent " white pollution ", meet environmental requirement.
Embodiment：
The present invention is a kind of fully degradable multifunctional liquid-state mulch film and preparation method thereof, and main component of the invention has：
1. using main adhesive filmogen of the organic hydrophilic adhesive lignin as liquid-state mulch film.Lignin has breast
Change dispersiveness, film-forming quality is stable, and excipient, water conservation, viscosity is big, and good fluidity is degradable, is resistant to inorganic salts and waits special with suspended by force
Property.
It is also the main material of medical capsule shells 2. Propiram glue is the wide variety of film forming agent of food industry and adhesive
Material, freely can quickly dissolve in water, expand.Solution is neutrality, is not ionized, not gelation, nodeless mesh, film forming is tough.Into
There is oil resistivity, gas barrier properties are heat-resisting after film, be the preferable toughener of liquid-state mulch film and crosslinking agent the features such as Salt And Alkali Tolerance.
3. calcium sulfate, borax, urea and pentose are liquid-state mulch film synergist, active matter in organic colloidal solution can be increased
GL-PP and carbon in the toughness of matter, the tensile strength and ductility of raising liquid film, improvement organic solution, nitrogen ratio, further
Improve into film toughness.Wherein borax, urea can provide part nutrient, improved soil after the progressively degraded of liquid film.
4. penoxsuam and bensulfuron-methyl are efficient, low toxicity, broad-spectrum herbicide.Can also be pyrazosulfuron, second fluorine sulphur
Grand, double second sulphurs are grand, one or more combinations in pretilachlor, butachlor, isopropyl methoxalamine, mefenacet.
The preparation method of the present invention is as follows：
Appropriate water is added in a kettle. and 35 DEG C -55 DEG C are heated to through 2000-4000 Gauss magnetization treatments, is added general
Shandong orchid glue, it is stirring while adding 1-3 minute, standing 20-40 minutes after be separately added into again lignin, penoxsuam, bensulfuron-methyl,
Calcium sulfate, borax, urea, pentose, are further continued for stirring until raw material all dissolves.
The application effect and substantive distinguishing features of the present invention：
1. product of the present invention is sprayed at into farmland surface natural drying in 4-9 hours forms one layer of 0.3mm-1.2mm thickness
The soil moisture can improve 2-3 DEG C under mulch film, film, and moisture in the soil substantially increases, under film herbicide effect substantially, seedling can voluntarily rupture of membranes it is long
Go out.Mulch film is gradually degraded after 30 days, is sustained into fertilizer.A fertilizer is added equal to crop.It is beautiful compared to the farmland for less applying film
Rice can increase production 10%, soybean yield-increasing 9%, wheat increase yield 8%, potato production promoting 5%, to soil without any pollution, it is possible to improve
Soil, increases fertility.
2. the present invention has following features compared with the mulch film applied on the market at present：
Mulch film is integrated with herbicide, fertilizer, with Multifunctional effect；
Cost is low, only the 2/3 of common ground film price, is easy to promote；
Seedling can directly rupture of membranes grow, save artificial；
It is easy to degraded, prevents " white pollution ", meet environmental requirement；
Water in liquid ground film raw material passes through magnetization treatment, can increase solubility of the mineral matter in water, increases film forming
Viscosity and toughness, accelerate the manure digestion in farmland, stimulate the growth of crops, greatly increase the quality and yield of crops.
