Description
Technical field
The invention belongs to biological soil conditioner technical field, by increase organic matter, repair microbial ecological circle, with up to
To change soil texture, reply soil fertility, productivity and design a kind of biological modification agent and preparation method.
Background technology
With the development of the social economy, people are to land use technical requirements also more and more higher, country needs substantial amounts of plough
Plant soil and produce cereal crops to meet national development need, but existing cultivated area is reduced year by year, while existing arable soil
Quality Down, soil degradation is serious, or even soil hardening, salinization of soil, has had a strong impact on the growth of crops, and yield goes out
Product.There is substantial amounts of saline-alkali wasteland really to be developed again in coastal and inland, these current resources situations by artificial measure in the urgent need to mending
Filling soil improves soil quality, eliminates salinization of soil, it is ensured that the yield and quality of agricultural planting level and crop products.And and this
One situation is corresponding, the research and development of the effective modifying agent technology of China and popularization relative deficiency.The alternative production of in the market
Product and modifying agent manufacturer are even more very few, and it is most of be in chemical composition method in inorganic salts sweetening of the soil, it is right
Follow-up agricultural planting harm is big, relies on serious to water source of fresh water, is adapted to transform paddy field as and be not suitable for the few dry land of fresh water and change
Make.Though with people in recent years to non-polluted farm product, pollution-free food, organic food pursuit more and more higher, it is large quantities of to this
Do not develop soil to pay attention to all the more, the development of the demand of improved soil and the demand driving modifying agent to modifying agent, and gradually make
Get up for industry development.But, nowadays in the market modifying agent kind a multitude of names, can really play the volume increase of increasing matter, improved soil
, it is few;Most of inorganic salts are that the investment of main modifying agent is big, and slowly effect, follow-up long-term cropping are easily dead.So for
Salt-soda soil can be administered while the modifying agent for taking into account follow-up agricultural planting is even more rare.
The content of the invention
It is an object of the invention to overcome defect of the prior art, and provide a kind of structure to alkaline land soil, soil
Nutrient, salinity, moisture, gas permeability and microbial activity in earth have it is highly important influence with reach recover soil fertility,
A kind of biological modification agent and preparation method of vigor.
The object of the present invention is achieved like this:The modifying agent is formulated by following raw materials according according to parts by weight:Poultry
500 parts of poultry manure, 100 parts of sawdust, 200 parts of fertile soil, 20 parts of peanut meal, 20 parts of bone meal, 150 parts of pine needle, 3 parts of zymophyte does
70 parts of feed with paper-mulberry leaf, does 80 parts of mulberry leaves, 47 parts of slaughterhouse leftover pieces.
A kind of biological modification agent, it is characterised in that:The fermented bacterium by:Trichoderma, blown-ball Azotobacter, withered grass bud
Spore bacterium, lactobacillus acidophilus and rhizobium composition:It is described:Trichoderma, blown-ball Azotobacter, bacillus subtilis, lactobacillus acidophilus, root nodule
The mass ratio of bacterium is 3:2:4:1:1.5;The effective unit of the Trichoderma is:300000000 CFU/ grams, blown-ball Azotobacter:300000000 CFU/
Gram, bacillus subtilis:2000000000 CFU/ grams, lactobacillus acidophilus:1000000000 CFU/ grams, rhizobium:2000000000 CFU/ grams.
A kind of preparation method of biological modification agent, the preparation method comprises the following steps:
Step 1:Bone meal, peanut meal are uniformly mixed into sterilization with the slaughterhouse leftover pieces after crushing, mixture and equal proportion is made
The uniform mixed fermentation of fermented bacterium 15 days after, the first fermentate is made;
Step 2:Feces of livestock and poultry, stalk, fertile soil, pine needle, dry feed with paper-mulberry leaf and dry mulberry leaves are mixed, then with the hair of equal proportion
After the uniform mixed fermentation of yeast-like fungi kind 10 days, the second fermentate is made;
Step 3:Later stage fermentation will be carried out after the second fermentate in the first fermentate and step 2 in step 1 uniformly mixing, after
By up to 2 meters of said mixture heap when phase ferments, the fermentation temperature of monitoring later stage fermentation in real time, turning in 10-15 days once, is fermented
Biological modification agent semi-finished product are made after 30-40 days;
Step 4:The semi-finished product of biological modification agent is sieved by screening machine, make to pack after big material therein is broken, i.e.,
Into finished product.Fermentation temperature in the step 3 is not higher than 50 DEG C;, can be by adding water or increasing when fermentation temperature is higher than 50 DEG C
The mode of turning number of times is cooled.Dry feed with paper-mulberry leaf in the step 2 is paper mulberry of the moisture content below 20% after drying
Leaf;Dry mulberry leaves are mulberry leaves of the moisture content below 20% after drying.
The dry feed with paper-mulberry leaf used in the present invention, feed with paper-mulberry leaf protein content is up to 20%-30%, amino acid, vitamin, carbon water
The nutritional ingredient leaf very abundant such as compound and trace element, by fermentation, the effect of flora can be for feed with paper-mulberry leaf and dry mulberry leaf
Its macro-molecular protein contained, the substance decomposition such as fiber and nucleic acid is into various peptides, amino acid, monose and other small molecule things
Matter is preferably absorbed for plant;
The present invention is with element that is with low cost, being needed rich in plant growth, and comprehensive nutrition, fertilizer efficiency are lasting, improved soil is ecological
Environment, the physicochemical property of improved soil, agricultural wastes minimizing, crops can be made to organise, quality and quantitation
Advantage.
The beneficial effects of the invention are as follows:
Salt-soda soil biological modification agent:Organic matter is sufficient, energy is abundant, adds the fermented bacterium for safeguarding Tiny ecosystem effect.Promote
Zymophyte growth and breeding, repairs microbial ecological circle, increases soil texture granule, adds the ventilative water permeability of soil.Soil
Earth is breathed freely, and root system can preferably breathe growth, permeable, and soil will not cause rotten root not in ponding, and survival rate of seedling is carried significantly
It is high.
