In addition, the invention also provides a preparation method of the algae liquid plastic film.
Description
Technical field
The present invention relates to the agricultural liquid mulch film, particularly, the present invention relates to a kind of biodegradable marine alga liquid-state mulch film and preparation method thereof.
Background technology
The agripast film-mulching technique is in the existing nearly 40 years history of China; Because film mulching and planting the effect of increasing income is remarkable; Make film-mulching technique become that economize on water with the Northeast's coping with agriculture drought in area, the wide northwestward in China high and cold, arid, semiarid, low-lying, saline and alkaline zone, particularly China, the important measures of increasing crop yield.At present, China's membrane covering area has reached 2.5 hundred million mu, and annual speed increase with 1,000 ten thousand mu uses total amount to surpass 450,000 tons in mulch film year, occupies first place in the world.
A large amount of uses of agripast mulch film cause the residual film of soil to be accumulated in a large number, and Land pollution is serious.Continuity along with the membrane covering time; The accumulation of residual film in soil plough horizon will cause soil aggregate to destroy, and the infiltration of soil capillary water and natural water seriously is obstructed, and soil porosity, permeability and water cut obviously reduce; Unit weight and specific density obviously rise; Directly influence soil microorganisms environment and soil and plough receipts, soil fertility is descended, cause the serious underproduction of crop.According to Ministry of Agriculture's researching determining, mulch film pollutes provinces, cities and regions such as more serious Beijing, Tianjin, Xinjiang, Heilungkiang, Shanghai, Hubei, in the topsoil in 5 years of continuous covering; The residual film accumulation volume of per hectare is generally between 90-135Kg, and with serious pollution place is up to 270Kg, crop failure 15%-30%; In addition, with the back damaged disastrously there's no one who doesn't or isn't to reclaim, directly burn in the field; The obnoxious flavour of its generation, influential Air quality; Residual film fragment mixes stalk and the feed of farm crop, is eaten by mistake by domestic animals such as cattle and sheep, causes the functions of intestines and stomach imbalance, and the growth of livestock is fallen for a short time or dead incident also happens occasionally.
Data shows that China desert, Gobi desert and the desertification land total area are 168.9 ten thousand square kilometres, account for 17.6% of area according to the relevent statistics in addition, and the whole nation nearly has that 1/3rd area is just receiving hazards of sand storms.Since the nineties, China's sandy land area is with the speed expanded in 2460 square kilometres of every year.By 1999, " engineering prevents and controls desertification " that China serves as theme with three Norths dust storm band administered 6.44 ten thousand kilometers in desert altogether, but still is in the state of " sand advances the people and moves back ".According to satellite remote sensing technique for investigation statistics, degeneration is being quickened with annual 2% speed in national grassland capable of using.Desertification brings direct harm to people's life with existence, and big and medium-sized cities, industrial and mineral and national defense facility are caused serious threat.It is extremely urgent to we can say that China prevents and treats the work of Desertification.
Liquid ground film is that relative solid mulch film is commonly called as by agreement.Liquid ground film itself is a kind of liquid, and being sprayed on after the face of land dehydration can the very thin one deck cured film of fixed formation, and this film has the soil moisture conservation of heating, water conservation, conserve water and soil, increase the soil aggregate effects such as physical behavior of improving the soil.Therefore there is demand at present for novel liquid-state mulch film.
Summary of the invention
The objective of the invention is to provides a kind of biodegradable marine alga liquid-state mulch film to the problems referred to above, and it is that main raw material supports with natural effective constituent wild or that propagate the treated extraction of marine alga artificially.
Another object of the present invention provides the preparation method of said biodegradable marine alga liquid-state mulch film.
Be used to realize that the technical scheme of above-mentioned purpose is following:
On the one hand, the present invention provides a kind of biodegradable marine alga liquid-state mulch film, and component and weight part thereof that this marine alga liquid-state mulch film is comprised are:
100 parts of Seaweed Extracts; ROHM seaweed gel resin 2-10 part; Ligninsulfonate 50-70 part; Humic acids 10-20 part; Molasses, biochemical fulvic acid salt or by molasses and biochemical fulvic acid salt weight ratio blended mixture 20-30 part with 1: 2; CMC 99.5 10-20 part; And water 300-500 part.
Wherein, said ligninsulfonate is preferably wooden calcium sulfonate, lignin sulfonic acid magnesium or wooden calcium sulfonate and lignin sulfonic acid magnesium with 1: 2 weight ratio blended mixture.
And said biochemical fulvic acid salt is biochemical potassium fulvate.
And said Seaweed Extract prepares through following steps:
1) with marine alga raw material pulverizing to 1 * 1-4 * 4cm;
2) preparation concentration is the sodium carbonate solution of 0.05-0.2mol/L;
3) marine alga and the step 2 that step 1) are obtained) sodium carbonate solution that obtains is according to weight ratio 1: 3-1: 11 formation mixtures;
4) under agitation with 55-100 ℃, the marine alga in the mixture that step 3) obtains was degraded 1-6 hour under the yellow soda ash effect, be cooled to normal temperature, centrifugal oven dry promptly gets.
Preferably, said marine alga raw material is the natural wild or marine alga propagated artificially.
Preferably, said marine alga raw material is one or more in limnetic dry kelp, dried sargassun and the dried wakame.
On the other hand, the present invention also provides the preparation method of above-mentioned marine alga liquid-state mulch film, and said method comprises that each component is mixed the back directly sprays film forming.
Below be detailed description of the present invention:
Provided by the present invention: the biodegradable liquid-state mulch film of a kind of marine alga; It is a main raw material with natural effective constituent wild or that propagate the treated extraction of marine alga artificially; Add ROHM seaweed gel resin, wooden calcium sulfonate, humic acids, molasses, CMC 99.5, water formation, its addition is that benchmark is counted respectively with the weight of Seaweed Extract: 100 parts of Seaweed Extracts; ROHM seaweed gel resin 2-10 part; The 50-70 of wooden calcium sulfonate part; Humic acids 10-20 part; Molasses 20-30 part; CMC 99.5 10-20 part; Water 300-500 part.
Such scheme can use lignin sulfonic acid magnesium to replace wooden calcium sulfonate, or both used by 1: 2;
Such scheme can use the biochemical fulvic acid potassio for molasses, and perhaps both used by 1: 2.
The wet tenacity of the biodegradable liquid-state mulch film of marine alga of the present invention is big, and water retention property is good; The Seaweed Extract active substance not only can increase the nutrition of plant up to 20%, has the effect of diseases prevention, expelling parasite, raising the output simultaneously, can also regulate the growth of plant, has stronger water retention; Lalgine has passivation to the heavy metal in the soil, stops the absorption of crop to heavy metal ion; Have favorable biological degradability simultaneously, product directly sprays film forming on the ridge, field, and film-forming process is simple, and convenient the use especially can keep the soil moisture, than the high 3-4 degree of the soil moisture that does not spray film.And this liquid ground film adds ROHM seaweed gel resin, has good water-retentivity; Add humic acids, have the chemical fertilizer of change characteristic, the structure of improving the soil, the physiological metabolism that stimulates crop, the enhancing crop adverse-resistant characteristic improves the effect of the sub-real mass of crop.
Generally speaking, marine alga liquid-state mulch film of the present invention can heat soil moisture conservation, water conservation, conserve water and soil, increase the soil aggregate effects such as physical behavior of improving the soil, and film-forming process is simple, be fit to the field fast, a large amount of operation.
