Description
Technical field
The invention belongs to soil conditioners, and in particular to a kind of modifying agent of soil hardening.
Background technology
It is seriously broken due to the predation formula farming of decades, nutrient loss, farmland quality in the arable land in many areas in China
It is bad.Excessively rely on chemical fertilizer use, arable land is made soil degradation generally occur, topsoil shoals, tilth is deteriorated, ability of declaring dutiable goods decline etc.
Phenomenon.
The birth of chemical fertilizer brings the hope of good harvest in the regular hour to peasant.However what long-time service chemical fertilizer generated
Drawback is following.First, soil is destroyed, soil organic matter content is caused to decline, all kinds of nutrients ratio imbalances, soil starts acid
To change, is hardened, the physicochemical character and soil microflora of soil are seriously destroyed, and cause its water conservation, fertilizer conservation, poor air permeability,
It is difficult to the actual growth needs for meeting crops；2nd, crops are stronger to the dependence of fertilizer and pesticide, it is necessary to which the increase phase makes year by year
Dosage, otherwise, crop growth are slow, and pest and disease damage is serious, cause the underproduction；3rd, agroecological environment deteriorates, and chemical fertilizer applies farmland
Afterwards, practical efficiency averagely only has 30%, and major part flows into rivers and lakes with agricultural drain or residues in soil and plant and agriculture
It in crop body, not only brings environmental pollution but also jeopardizes the safety and health of the mankind and life, it is sustainable that these all become agricultural
The obstacle of sexual development.
There is provided a kind of modifying agent of soil hardening becomes the hot spot of agricultural development research.
The content of the invention
It is an object of the invention to provide a kind of modifying agent of soil hardening, using various agricultural discarded object and bacteria agent
It is used cooperatively, can not only can dissolve the phosphate in soil, recover crumb structure in the form of key bridge, eliminate soil hardening, and
And abundant trace element and organic matter are provided, improve loosing soil and storing water and preserving fertility ability, improve crop yield.
The specific technical solution of the present invention is as follows：
The modifying agent of a kind of soil hardening provided by the invention, including following raw material：
The composite bacteria agent is made of the microbial inoculum of following parts by weight：
1-2 parts of 3-4 parts of bacillus subtilis, 2-3 parts of Aspergillus and Li's Trichoderma.
Preferably, the attapulgite is modified using the preceding acid that carries out；
It is described acid modification be specially：Attapulgite and calgon are placed in acid solution, are ultrasonically treated, filtering,
After being dried under the conditions of 105-110 DEG C, ground 200-400 mesh sieves are to get attapulgite modified.The supersound process refers to room temperature
Lower supersound process 1-2h.
Further, attapulgite, the mass ratio of calgon are 100:4-5；The attapulgite and acid solution of addition
Amount ratio be 1:6-10g/ml.The attapulgite in percentage by weight, including following substance：Attapulgite 50%-
80%, dolomite 10-30%, quartz and feldspar impurity content are not more than 10%.Original producton location：Xuyi Jiangsu.The acid solution choosing
From salpeter solution or hydrochloric acid solution, the concentration of the acid solution is 0.5-2mol/L.
Preferably, the bagasse crushed 20-40 mesh sieves using preceding drying.
The wheat straw is cut into 4-5cm sections using preceding drying, and lime powder, and ventilation is dried, and crushed 10-20 mesh sieves.
The banana skin crosses 10-20 mesh sieves using preceding drying.
The Waste compost crosses 10-20 mesh sieves using preceding drying.
The preparation method of the modifying agent of the soil hardening is：
1) by weight, 10-20 parts of 2-5 parts of composite bacteria agent, 20-30 parts of wheat straw, 15-20 parts of dregs of beans and rice bran are mixed,
Add 40-60 parts of deionized waters, stir and evenly mix, ferment；
2) 5-8 parts of 3-7 parts of Waste compost, 15-30 parts of bagasse and banana skin are added in into mixed material prepared by step 1),
It stirs and evenly mixs, ferments；
3) by step 2) ferment after drying materials, pulverize and sieve, with 1-3 parts of mixings of attapulgite to get.
Step 1) the fermentation refers to the 2-10h that ferments at 55-65 DEG C, and fermentation process keeps air humidity in 65-85%.
Step 2) the fermentation refers to ferment 1-2 days at 15-35 DEG C.
Drying refers to dry 3-5h under the conditions of 50-60 DEG C described in step 3).
60-80 mesh sieves are sieved through described in step 3) excessively.
The crumb structure of soil is the important indicator of soil fertility, and the destruction of soil aggregate structure causes soil water-retaining, protects
Fertile ability and permeability reduce, and cause soil hardening.The content of organic matter is an important finger of soil fertility and crumb structure
Mark, the reduction of organic matter cause soil hardening.Pass through in addition, soil aggregate structure is electronegative soil clay particle and organic matter
What the polyvalent cation connection of positively charged formed.Soil particle is connected into bulky grain in the form of key bridge and forms soil by polyvalent cation
Earth crumb structure.Cation in soil is based on the calcium and magnesium ion of divalent, when phosphate fertilizer is excessively applied into soil, in phosphate fertilizer
Phosphate anion combines to form insoluble phosphate with cations such as calcium, magnesium in soil, that is, wastes phosphate fertilizer, and destroy soil group
Kernel structure causes soil hardening.
The bacillus subtilis added in the present invention inhibits and kills the harmful bacteria in soil and pathogen；Aspergillus is accelerated
The decomposing and fermenting of stalk, dregs of beans etc.；Li's Trichoderma can release pedo relict toxin, coordinate the use of attapulgite, favorably
In the absorption of heavy metal in soil, arsenic etc., soil health degree is improved.In addition banana skin, bagasse are added in the present invention and is given up
Mushroom bran is not only that 3 kinds of compounding microbial bacterial agents provide organic matter and abundant trace element, and the growth and breeding of microorganism is promoted to give birth to
Long, cooperation Waste compost contains glucide, amino acid, peptides, nucleic acid and trace element, also swashs containing the biology that species is enriched
Element promotes beneficial microbe breeding, improves the microorganism species in material, above-mentioned compounding microbial reproduction is promoted to be metabolized after fermentation,
The substances such as organic acid are secreted, can dissolve the phosphate in soil, k adsorption, calcium zinc etc., recover granule knot in the form of key bridge
Structure improves loosing soil degree and gas permeability, eliminates soil hardening；Moreover, wheat straw, dregs of beans, rice bran, bagasse, Waste compost and perfume (or spice)
Any of several broadleaf plants skin passes through fermentation maturity, provides organic matter and trace element for soil, eliminates soil hardening.Bagasse and Waste compost plus
Enter, improve the gas porosity and gas permeability of soil, improve the ability of soil water storage fertilizer conservation.
Compared with prior art, modifying agent provided by the invention is rich in organic matter and trace element, and cooperation microbial inoculum is used, disappeared
Except soil hardening, the harmful substance of soil enrichment is eliminated, is increase soil fertility, improve soil nutrient structure, improve loosing soil
Property and storing water and preserving fertility ability, promote plant growth, improve yield.
