Description
Technical field
The present invention relates to agricultural liquid-state mulch film field, particularly relate to a kind of Sargassum liquid ground with weeding function
Film powder and using method thereof.
Background technology
During proportion of crop planting, it will usually cover plastic film after proportion of crop planting on earth's surface, rise
To insulation, moisture-keeping function, so that crops early emerge, precocious and raising yield.Traditional plastic film
More bother when transport, overlay film, winder, affect efficiency.Additionally, plastic film is easily run by wind,
Affect crop growth.And plastic film is easily broken, fragment reclaims difficulty after remaining in soil, no
Degradable, cause soil contaminated, cause soil block to harden, fertility declines.
Authorization Notice No. is CN103613460B, the Chinese invention patent in filing date on November 25th, 2011
Disclose a kind of liquid-state mulch film function, preparation and using method thereof.Its main technical schemes is: take mud,
Add the biocide deodoring and disinfecting being made up of water-soluble sym-closene；Be subsequently adding the former powder of humic acid,
After inorganic salt and water mix and blend homogenizing, then make, by grinding, reacting, the masterbatch that body of paste is constituted；Take poly-
Acrylamide and derivant thereof, lignosulfonates or/and cellulose derivative constitute have film forming, infiltration,
The son material of dispersion, chelating and water retention property；By water, above-mentioned sub-material is dissolved during use, then be added into masterbatch
Atherosclerotic body is made in middle stirring, then adds water agitation and dilution uniform, can be formed mulch film by atomizers spray.
It is that liquid-state mulch film prepared by major ingredient by mud, the most substantially solves a difficult problem for Treatment of Sludge, more importantly make
Its turn waste into wealth can culture fertility significantly, and have the function heating, preserving soil moisture, promote plant growth, it is achieved
Eliminate " white pollution ", the control agricultural airborne dust factor, improvement soil, saving water resource, increasing peasant income joint,
Promote agricultural sustainable development.
The liquid-state mulch film of technique scheme to some extent solves the problem of " white pollution ", and profit
Turn waste into wealth with mud, energy-conserving and environment-protective, but the water conservation of this liquid-state mulch film, heat insulation effect are not ideal enough, and
Functional the most single.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of algae liquid plastic film with weeding function
Powder and using method thereof.After a procedure, the film-formation result on earth's surface is good for the algae liquid plastic film powder of the present invention,
Can improve Soil structure, water conservation, heat insulation effect are outstanding, easily degrade, and have weeding, promote farming
The function of thing root growth.
The concrete technical scheme of the present invention is: a kind of algae liquid plastic film powder with weeding function, by following
The material composition of mass parts: Sargassum extract powder 20-40 part, polyvinyl alcohol 3-5 part, carboxymethyl cellulose 3-5
Part, fibroin powder 3-5 part, oxygenation agent 3-5 part, weeding particle 1-2 part.
The algae liquid plastic film powder of the present invention is after being watered, due to Sargassum extract powder, polyvinyl alcohol, carboxymethyl
Cellulose, the existence of fibroin powder, form the liquid with certain stickiness, after being sprayed onto soil surface,
Can quickly form the film of layer of gel shape, can suppress soil water evaporation after film forming, heat scatters and disappears, and rises
To water conservation, the effect of insulation.This film is strong with the adhesion of soil, and the soil particle in soil can be coupled to reason
The aggregate thought, thus improve Soil structure, make soil have preferable permeability, be suitable for the life of crops
Long.In this liquid mulching film powder, Sargassum extract powder, polyvinyl alcohol, carboxymethylcellulose component have outstanding guarantor
Wet function, compounding with fibroin powder after and film property, caking property good, and film forming caudacoria has countless vertical
The fine duct of body, adds soil and extraneous permeability, it is simple to " respiratory ventilation ", but is unlikely to make
Heat distributes rapidly, is particularly well-suited to the main component of liquid-state mulch film.This can be natural after having liquid-state mulch film to spray
Degraded, environmentally safe, environmental protection.
Preferred as the technical program, described Sargassum extract powder is prepared by following methods: cut by described Sargassum
Broken unqualified for Sargassum, then by steaming and decocting 5-10min in unqualified for the Sargassum boiling water adding its 100-200 times of quality to；
Then by unqualified for Sargassum taking-up dewatering, it is added in the sodium pyrophosphate solution of 10-20 times of quality, and surpasses
Sonicated 1-2h, prepares Sargassum mucus；Wherein the mass concentration of sodium pyrophosphate is 3%, ultrasonic Treatment temperature
Degree is for 65-70 DEG C, and ultrasonic power is 800-1200W, and ultrasonic frequency is 18-22kHz；To Sargassum mucus
Middle dropping sodium hydroxide solution is adjusted to neutrality, is finally concentrated by Sargassum mucus, i.e. prepares Sargassum extraction after drying
Powder.
Extract the Sargassum extract powder obtained as stated above, there is abundant Sargassum polysaccharides and other active matters
Matter, not only film property, moisture retention are good, also can strengthen soil fertile as the regulator of soil after auto-degradation
Power.
Preferred as the technical program, described fibroin powder is prepared by following methods: silkworm silk is immersed into 6g/L
Solution of potassium carbonate at 96-98 DEG C, carry out degumming 40min, and change solution of potassium carbonate when 20min,
Wherein silkworm silk is (2-3) g/100mL with the solid-to-liquid ratio of solution of potassium carbonate；After degumming, silkworm silk taken out and use water

To protection, slow releasing function, prevent the too fast inefficacy of urea peroxide, SODIUM PERCARBONATE.And simultaneously beta-schardinger dextrin-and water
After in conjunction with in the pasty state, it is easy to things such as Sargassum extract powder, polyvinyl alcohol, carboxymethyl cellulose, fibroin powder
Matter is compatible.After liquid mulching film powder is watered sprinkling, oxygenation agent penetrates in soil, slowly discharges oxygen, time
Effect is long, it is possible to promote crop root part growth.
Preferred as the technical program, described weeding particle is prepared by following methods: herbicide is dissolved in water
In to prepare mass concentration be the weeding liquid of 1-2%, nano-attapulgite is added to weeding liquid carries out ultrasound wave
Dispersion, then it is filtrated to get weeding particle after standing 1-2h.Weeding liquid, nanometer is made after herbicide is dissolved in water
Attapulgite has the strongest adsorptivity, distributes it to adsorb weeding liquid in weeding liquid, with
After other compositions of liquid mulching film powder together add water, make the herbicide stability in weeding liquid more preferable, after sprinkling
Herbicide can penetrate on soil, plays herbicide effect, and the concrete addition of nano-attapulgite does not limits,
Ensure its saturated absorption weeding liquid.
Preferred as the technical program, described herbicide removes selected from alachlor, Acetochlor, butachlor, grass
One or more in spirit, N,N'-dimethyl-.gamma..gamma.'-dipyridylium.
The using method of a kind of algae liquid plastic film powder with weeding function, step is: by described Sargassum liquid
Each material in state mulch film powder is mixed by proportioning, and then algae liquid plastic film powder adds to its 8-12 times of quality
Water in be stirred, after stirring prepare mulching liquid, described mulching liquid is sprayed to soil surface.
The liquid mulching film powder using method of the present invention is convenient, and efficiency is high.
It is compared with the prior art, the invention has the beneficial effects as follows: the algae liquid plastic film powder of the present invention is using
After, the film-formation result on earth's surface is good, it is possible to improve Soil structure, water conservation, be incubated, the effect that preserves soil moisture outstanding,
Easily degraded, and there is weeding, promote the function of crops root growth.
