Description

A kind of middle micro element organic bio-fertilizer and preparation method thereof
Technical field
The present invention relates to technical field of fertilizers more particularly to a kind of middle micro element organic bio-fertilizer and preparation method thereof.
Background technology
According in plant content number, 4 kinds of calcium that content is 0.1%-0.5%, magnesium, sulphur and silicon elements are middle amount member Element, zinc, boron, manganese, molybdenum, copper, iron, chlorine are the necessary 7 kinds of trace elements of plant.The survey showed that, and China's most area is all deposited In different degrees of microelement deficiencies.Although in both at home and abroad, the yield of micro element fertilizer and consumption figure all gradually increasing, also take Obtained different degrees of effect, but because its is of high cost, and be mainly used for the fields such as flowers, lawn, also have in modern agriculture it is involved, Large-scale application is had no in production of forestry.The fertilizer of application in forestry, with requirement agriculturally without what in kind Difference, but the production cycle of forestry is long, the uniqueness of mountainous region parent rock characteristic and forest ecosystem Microelemental cycle, makes existing In having, micro element fertilizer, it is difficult to match with Mountain Area Forestry regulation of fertilizer requirement.
In forest ecosystem, nutrient is concentrated mainly in soil and botanical system, rainfall input, linear reservoir, The processes such as the output of products that wood producing, hayashishita development of resources are formed affect forest ecosystem nutrient balance.It is given birth in timber In the case that biomass is taken away in production and forest products output, if not supplementing suitable trace element, Trace Elements in Soil will Tree growth needs cannot be met.Therefore, a kind of middle micro element fertilizer disclosure satisfy that tree growth demand of research and development has important Meaning.
Invention content
Microelement deficiencies in there are problems that for existing tree growth process, it is organic that the present invention provides a kind of middle micro element Bio-fertilizer and preparation method thereof.
To achieve the above object of the invention, present invention employs the following technical solutions:
A kind of middle micro element organic bio-fertilizer, including component that mass fraction is following:
45-50 parts of mushroom bran;
15-20 parts of attapulgite;
Middle trace element fertilizer 20-32 parts;
8-10 parts of bio-bacterial manure;
3-5 parts of lignin peroxidase;
3-5 parts of cellulase;
The mushroom bran is that agrocybe mushroom bran, mushroom mushroom bran and oyster mushroom mushroom bran mass ratio are (3-5):(2-4):(1-3's) is mixed Object is closed, agrocybe mushroom bran main component is containing 75% cotton seed hulls, 15% wood sawdust;Mushroom mushroom bran main component is 78% wood sawdust; Oyster mushroom mushroom bran main component is 95% corncob.
Specifically, mushroom bran not only contains relatively rich kind of carbohydrate, organic acid organic matter, and it is a variety of also to contain copper, zinc, iron etc. Trace element, cellulose, hemicellulose, lignin and anti-nutritional factors therein are by different degrees of degradation;And tea tree Monosaccharide in mushroom chaff and mushroom mushroom bran is mainly glucose and galactolipin, and the monosaccharide in oyster mushroom mushroom bran is mainly galactolipin, and three Kind mushroom bran is with the use of enough nutrients are provided for the thalline in fermentation process, the anti-nutritional factors in mushroom bran of effectively degrading, and Organic matter and bioactive substance content are improved, the fertility of organic bio-fertilizer is improved.Using edible fungus bran people's soil is applied as fertilizer In earth, the content of soil with organic matter can be increased, increase soil fertility, and the aeration and water holding of soil can be improved well Property.
Specifically, lignin peroxidase can digest the lignin in soil, and it is small molecule object to make lignin degradation Matter, and then improve the fertility of soil;Cellulase in decomposition of cellulose from biocatalysis, can by cellulose decomposition at Oligosaccharides or monosaccharide, lignin peroxidase have formed the multicomponent enzyme system of synergistic effect with cellulase, in soil of degrading Lignin and cellulose further improve the vigor of soil.
Preferably, the middle trace element fertilizer is complexing of glycin iron, lysine complex copper, lysine complexing manganese, amino At least one of sour magnesium complex or lignin sulfonic acid zinc can select different micro- ammonia according to tree growth demand Base acid complex is compounded, and required a variety of amino acid and trace element, microelement amino acid chelate are provided for forest Coordinate bond and ionic bond between middle metallic element and amino acid, which are combined, promotes the stability of amino acid complex stronger, can be effective Antagonism is prevented, is not easy to be fixed in the soil, it is soluble easily in water, and be not easily decomposed, there is slow-release function, fertilizer efficiency is lasting, can be well It is absorbed and used by plants, amino acid especially therein can directly be absorbed by forest, in addition, middle trace element fertilizer also can be with it His solid-state or liquid fertilizer mixing application do not reduce the fertilizer efficiency of any fertilizer, and the micro member of complex compound without chemically reacting Element is cheap, can reduce fertilizer cost.
Preferably, the middle trace element fertilizer is grouped as by the following group of mass fraction:
10-15 parts of complexing of glycin iron;
1-2 parts of lysine complex copper;
3-5 parts of manganese is complexed in lysine;
3-5 parts of amino-acid complex magnesium;
3-5 parts of lignin sulfonic acid zinc,
Trace element in a variety of amino acid and zinc, iron, copper, magnesium, manganese etc. is provided for plant growth, is used cooperatively and changes with mushroom bran The content of organic matter and middle trace element in kind fertilizer.
Preferably, it is (1-2) that the bio-bacterial manure, which is mass ratio,:(1-2):(1-2):(0-1):The nitrogen-fixing bacteria of (0-1), solution Phosphorus bacterium, potassium solubilizing bacteria, photosynthetic bacteria and bacillus act on lignin peroxidase, cellulase synergistic, through everfermentation and Cellulose, hemicellulose, lignin and the anti-nutritional factors in mushroom bran of further degrading are digested, and improves various saccharides, have Machine acids and bioactive substance content improve the fertility of organic bio-fertilizer.
Compared with the existing technology, middle micro element organic bio-fertilizer provided by the invention, uses mushroom bran for organic fertilizer, is forest The various trace elements such as abundant organic matter and copper, zinc, iron are provided, with bio-bacterial manure, lignin peroxidase and cellulose Enzyme acts synergistically, and lignin and cellulose in mushroom bran of further degrading improve various saccharides, organic acid and bioactivity Content of material improves the fertility of organic bio-fertilizer;Middle trace element fertilizer provides the same of required a variety of amino acid for tree growth When, with mushroom bran with the use of the content of the middle trace element of adjustment fertilizer, middle trace element fertilizer stability is stronger, there is sustained release work( Can, keep fertilizer efficiency more permanent, the microelement amino acid chelate in organic substance and middle trace element fertilizer in mushroom bran can Improve SOIL GAS, three Phase Proportion of solid, liquid, gives full play to edaphon improvement and vegetable soil function, improve soil nutrient knot Structure improves efficiently using for soil nutrient, provides plant growth indispensable middle trace element, enhances the light and work of plant With promotion root growth prevents root system from rotting, and promotes growth and development of plants, and enhancing plant is drought-resistant, low-temperature resistance, inhibits germ The performances such as insect pest.
The present invention also provides the preparation methods of micro element organic bio-fertilizer among the above, include the following steps:
(1) each component is weighed according to the raw material proportioning of the middle micro element organic bio-fertilizer;
