Description
Technical field
The present invention relates to a kind of soil conditioner with heavy metal adsorption effect, belong to fertilizer manufacture field.
Background technology
Soil is one of mankind's Main Natural Resources of depending on for existence, is also the important component part of human ecological environment.Along with the fast development of global economy, the pollutent containing heavy metal enters soil by all means, causes the enrichment of corresponding heavy metal element in soil.Soil pollution not only affects agricultural output and quality, and relates to air and quality of water environment, and endangers the life and health of animals and humans by food chain.
Current China suffers the arable land of heavy metal contamination about to have 0.1 hundred million hectares, account for 10% of total cultivated area, the whole nation reaches 1,200 ten thousand tons by the grain of heavy metal contamination every year, because causing grain drop in production up to more than 1,000 ten thousand tons by heavy metal contamination, and direct economic loss more than 200 hundred million yuan.According to the national irrigating region investigation that the Ministry of Agriculture of China carries out, in the Irrigation District of Sewage of about 1,400,000 hectares, the land area of heavy metal contamination is suffered to account for 64.8% of Irrigation District of Sewage area, wherein slight pollution account for 46.7%, intermediate pollution account for 9.7%, severe contamination account for 8.4%, wherein maximum with Hg and Cd contaminated area.According to State Environmental Protection Administration's investigation display, the developed areas such as Pearl River Delta, the Yangtze River Delta, Circum-Bohai Sea, are all faced with serious heavy metal pollution of soil problem.Heavy metal pollution of soil can cause physiological function of plants disorderly, nutritional trouble, and after entering human body by food chain, potential hazard is very big.Under this situation, heavy metal pollution of soil more and more receives the concern of people, has become the important environmental problem that the whole world faces.
The method of current restoration of soil polluted by heavy metal has peripheral doses, chemical redemption, phytoremediation etc., conventional physical chemistry reparation comprises Soil leaching and electro reclamation, chemosetting etc., such as add lime, phosphatic rock, zeolite etc., change its existing forms in soil by the absorption of heavy metal ion or (being total to) precipitating action, thus reduce its biological effectiveness and transport property.Phytoremediation refers to certain specific plant growing on the soil of heavy metal contamination, and this kind of plant has special absorption accumulation ability to the pollution element in soil, this heavy metal species can be shifted out the soil body after dealing carefully with by plant harvest, reach the object of Pollution abatement and restoration of the ecosystem.At present still there is the drawbacks such as inconvenient operation, effect are slow in physico-chemical processes or phytoremediation improvement heavy metal contamination soil in actual applications, significantly improves soil remediation cost.
Bio-organic fertilizer product is soil improvement product emerging at present; in the improvement field such as edatope, heavy-metal contaminated soil reparation, there is good application prospect; there is the advantages such as result of use is good, non-secondary pollution, progressively realizing large-scale promotion application.
Summary of the invention
For making up the deficiency of existing soil improvement product on improvement farmland soil heavy metals anti-contamination function, the invention provides a kind of soil conditioner with heavy metal adsorption effect, object is to improve agricultural land soil physicochemical character, utilize the active function groups absorption soil heavy metal ion contained by organic materials, microorganism is utilized to promote the release of nutrient in soil, promote the formation of soil aggregate, improve soil porosity, recover soil fertility, improve the foodstuff production-increasing potential in heavy-metal contaminated soil farmland.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
The invention provides a kind of soil conditioner with heavy metal adsorption effect, its feature specifically comprises the following steps:
(1) bio-fermentation agent preparation: get 5 ~ 10 parts of subtilises, 2 ~ 5 parts of Bacillus licheniformis, 1 ~ 2 part of bacillus megaterium, 10 ~ 15 parts of gacs, 10 ~ 15 parts of peats composed of rotten mosses, 3 ~ 5 parts of yeast powders, 15 ~ 20 parts of amino acid powders, 2 ~ 3 parts of dipotassium hydrogen phosphates, 5 ~ 8 parts of residue of monosodium glutamate, mixing and stirring; Then with the molasses fermented liquid containing 3%, mixture moisture is adjusted to 15 ~ 25%, 20 DEG C of condition lower seal anaerobically fermenting 3 ~ 5d, prepare bio-fermentation agent;
(2) mix: mix in the ratio of 3 ~ 5 parts of bio-fermentation agents, 20 ~ 30 parts of sugared slags, 30 ~ 45 parts of furfural dregs, 10 ~ 15 parts of cotton dregs, 5 ~ 10 parts of crushing straws, 1 ~ 2 part of cellulase, adjusts mixture moisture to 15 ~ 25% with the molasses fermented liquid containing 3%;
(3) Secondary Fermentation: by the 3 ~ 5d that becomes thoroughly decomposed under mixed mixture temperature control 20 ~ 30 DEG C of conditions, regular turning;
(4) prepare burden: after compost maturity terminates, add 20 ~ 30 parts of humic acidss, 35 ~ 50 parts of medical stone powders, 10 ~ 15 parts of attapulgites, mix;
(5) pulverize: use half wet stock pulverizer to pulverize the material completing Secondary Fermentation, smashing fineness will reach 30 ~ 50 orders;
(6) granulation: carry out cylinder granulation to roller pelletizer by through fermentation and the mass transport after pulverizing;
(7) dry: the particle after granulation is carried out drying and processing, and namely water content obtains soil conditioner finished product 10 ~ 15%.
The invention provides a kind of soil conditioner with heavy metal soil remediation effect, product utilization sugar slag, furfural dregs, cotton dregs, crop material are that main raw material passes through microorganism fermentation process, be aided with humic acids, medical stone powder, attapulgite etc. obtained, quality product meets the requirement of biological organic fertilizer NY884-2012, organic content >=40% in product, biologic live bacteria number >=0.2 hundred million/g, the requirement of heavy metal index conformance with standard.
The invention provides a kind of soil conditioner with heavy metal soil remediation effect, it is organic that product has bio-organic fertilizer, environmental protection, efficient feature, be rich in natural organic matter composition and (be rich in hydroxyl, phenolic group, ketone group, phenolic hydroxyl group active function groups), microorganism active composition and a large amount of probiotic bacterium, energy active adsorption Heavy Metals in Contaminated Soils ion, regulate the balance of Soil Microorganism, decompose the organic matter in soil, the organic or inorganic compositions such as mineral substance, alleviate the phenomenon such as heavy metal-polluted soil enrichment and crop murder by poisoning because environmental pollution causes, effectively improve soil physics structure and chemical composition, improve quality of agricultural product, it is a kind of excellent heavy-metal contaminated soil renovation agent.
