Abstract
The invention discloses a biological improvement method of sand degraded soil. The method combines humic acid and microorganism bacteria agent to prepare soil restoring agent. The soil restoring agent is covered on ditches and used in sand degraded soil with liquorice after the beginning of spring and before summer; the field management should be done for 1 year to 2 years. The invention can rapidly increase the content of organic matter in soil and increase types and quantity of microbe in the soil; thus the invention improves the ecological environment of soil and achieves the purpose of improving the sand degraded soil.
Description
Technical field
The present invention relates to the improvement of sand desertification soil, specifically, the present invention is a kind of biological modification method of sand desertification soil.
Background technology
China is one of maximum country of husky in the world degraded land, also is to be subjected to one of the most serious country of desertification harm.The husky degeneration area in territory reaches 1.26 hundred million km
2, mainly be distributed in northern China arid and semi-arid area, and expanding area increases year by year.The later stage nineties, (1995-1999) enlarged 3436km every year on average
2Only degenerate to plough and just account for 40% of total cultivated area in the whole nation, the degeneration grassland accounts for and can utilize 25% of grassland area; Wherein the meadow of China's arid, semiarid region and arable land degeneration area have reached 59.5% and 49.6% respectively, far above global mean level (ML).Serious day by day desertification of land is degenerated, and causes the deterioration of the ecological environment, the soil erosion aggravation, and sandstorm takes place frequently.According to the whole nation remote sensing investigation result second time, water-caused soil loss in China area 3,560,000 km
2, account for area 37.1%, at present still with annual 10000km
2Speed increase.Spring in 2000,15 sandstorms on a large scale just took place in the northern area of China, and soil erosion and sandstorm have increased the weight of the desertification of soil again degenerates, thereby has formed vicious cycle.The essence that soil desertifies is exactly serious Soil degradation, comprises physical degradation, chemical degradation and the biodeterioration of soil, and the key of control and land restoration Desertification is to prevent and treat Soil degradation.But, the present method that does not also have effective control Soil degradation.
Summary of the invention
The present invention has overcome above-mentioned shortcoming, has proposed a kind of biological modification method of sand desertification soil.
The present invention solves the technical scheme that its technical problem takes:
This method adopts humic acid and the compound soil remediation preparation that makes of microbiobacterial agent, and summer, the trench digging covering in season before arriving was applied in the sand desertification soil of planting Radix Glycyrrhizae after the beginning of spring, and through the field management in 1～2 year.
Microbiobacterial agent is made up of Bacillus licheniformis (Bacilus.licheniformis), S. cervisiae (Saccharomyces cerevisiae), subtilis (Bacilus subtilis), penicillium oxalicum (Penicillium oxalicum), streptomyces nigrificans (Streptomyces.nigrificans), trichoderma harziarum (Trichoderma harzianum).
The synergy of each microorganism is the formation that promotes soil aggregate in the soil-repairing agent.Effect was more obvious when particularly thread fungus fungi and actinomycetes bonding soil particle formed coacervate.The soil organism only under action of microorganisms, just has the effect of reunion grogs.Soil microorganisms is bonded together noncrystalline emplastic organism nearly, and organism further coheres the mineral particulate, forms the spherical surface coacervate.
Humic acid has no particular limits.Bagasse can be pulverized layer in airtight proving room,, make humic acid through 20～70 ℃ of continuous fermentations of 10 days; Also can adopt Chinese ZL03138767.5 (patentee: Luzhou Bio-Chemical Co., Ltd., Zhao'an County, Fujian Prov., Granted publication day: on November 23rd, the 2005) humic acid of being put down in writing.
In the complex micro organism fungicide, each action of microorganisms is as follows:
Bacillus licheniformis: decompose xylogen by thalli growth, improve the content of the soil organism, promote other microbial growths; Preferred Bacillus licheniformis ACCC 11080.
S. cervisiae: by thalli growth secretory product decomposing organic matter, improve the available effective constituent of microorganism growth in the environment, increased kind and the quantity of microorganism in the environment; Preferably saccharomyces cerevisiae bacterium ACCC 20251.
Subtilis: growth and macromolecular substance such as secretion meta-bolites degraded cellulose, hemicellulose by thalline, increase the available effective constituent of microorganism growth, promote microbial growth in the environment; Preferred subtilis ACCC 11089.
Penicillium oxalicum: by the secretory product of thalline, the acid or alkali environment of improving the soil improves the microorganism polymorphism in the soil, increases the organic content of soil; Preferred penicillium oxalicum ACCC 30400.
Streptomyces nigrificans: by the growth and the metabolic secretion thing of thalline, decomposition of cellulose promotes the increase of soil microorganisms kind and amount effectively, improves the organic content of soil; Preferred streptomyces nigrificans ACCC 40028.
Trichoderma harziarum: suppress the growth of soil-borne pathogen, increase the content of the soil organism, promote the formation of soil agreegate, help improving the microbial diversity in the soil; Preferred trichoderma harziarum ACCC 30422.
Various microorganism Bacillus licheniformis (ACCC11080), S. cervisiae (ACCC20251), subtilis (ACCC11089), penicillium oxalicum (ACCC30400), streptomyces nigrificans (ACCC40028), trichoderma harziarum (ACCC 30422) by Chinese agriculture microbial strains preservation center preservation (referring to Chinese agriculture bacterial classification catalogue, Chinese agriculture microbial strains preservation administrative center compiles, version in 2005, Chinese agriculture science and technology press).
Soil-repairing agent of the present invention adopts the microorganism of following weight ratio:
Bacillus licheniformis ACCC 11,080 2～10wt%
S. cervisiae ACCC 20,251 3～15wt%
Subtilis ACCC 11,089 3～20wt%
Penicillium oxalicum ACCC 30,400 1～10wt%
Streptomyces nigrificans ACCC 40,028 1～10wt%
Trichoderma harziarum ACCC 30422 surpluses.
The amount of application of soil-repairing agent is 25～75kg/ mu.
The invention has the advantages that: microorganism used therefor agent kind is the combination of the microorganism of several critical functions, the microorganism of used combination can lignin degrading, Mierocrystalline cellulose, hemicellulose macromole, biological humic acid is the tunning of bagasse in addition, wherein contain multiple organic composition, increase the available nutrient of microorganism in the environment, promoted the diversity growth of microorganism.Wherein Bacillus licheniformis has the decomposition xylogen, improves the effect of the soil organism; The acid or alkali environment that penicillium oxalicum can be improved the soil improves the microorganism polymorphism in the soil, increases the organic content of soil; S. cervisiae can be improved the content of soil with organic matter, increases the value volume and range of product of soil microorganisms; Macromolecular substance such as subtilis can degraded cellulose, hemicellulose increase the available effective constituent of microorganism growth, promote microbial growth in the environment; Streptomyces nigrificans is decomposition of cellulose effectively, promotes the increase of soil microorganisms kind and quantity, improves the organic content of soil; Trichoderma harziarum can suppress the growth of soil-borne pathogen, increases the content of the soil organism, promotes the formation of soil agreegate, helps improving the microbial diversity in the soil.The present invention can increase the organic content of soil fast, improves the microbe species and the quantity of soil, thereby improves the ecotope of soil, reaches the purpose of improvement sand desertification soil.
