Description
Technical field
The present invention relates to the preparation method of the preparation field of fertilizer, specifically selenium-enriched foliage fertilizer.
Background technology
Since reform and opening-up, China's agricultural production has obtained significant progress, however, chronic administration chemical fertilizer brings soil
Structure destruction, water pollution, utilization rate of fertilizer declines and the serious negative issues such as quality of agricultural product reduces.Currently, China is eaten
Product security situation is still severe, and the pollution of agricultural product source ranks first.Soil is the supplier of nutrient, and soil is nutrient again
Protect and store agent, be that other materials are irreplaceable, adjust soil, improvement soil, bring up soil, recover soil vitality, display is unearthed
The natural gray of earth, is the only way of food security, human civilization and scientific development.
And in agricultural production process, the use of fertilizer is essential again, so all the time, people are carrying out fertilizer
The research improvement of material, it is desirable to which it is even harmless to obtain endangering soil and crop very little, but can play and weigh in agricultural production
The fertilizer to be acted on.The species of domestic fertilizer is various, but its utilization rate is generally relatively low, is only 30%-40%, which results in fertilizer
Massive losses, therefore, how to improve utilization rate of fertilizer is urgent problem to be solved in China's agricultural production process.
The content of the invention
It is an object of the invention to provide a kind of preparation method is simple, favorable reproducibility, the wide selenium-enriched foliage fertilizer of raw material sources
Preparation method.Obtained organic fertilizer can provide the moderate-elements such as N, P, K essential element needed for plant growth, Ca, Mg, S
It is micro- with Fe, Mn, Zn etc., the selenium element of abundance can be particularly provided, promote plant growth；The time being attached on blade face
Long, slow release is good, and utilization rate is high, to the toxic effect of pest.
The present invention is directed to the problem of being mentioned in background technology, and the technical solution taken is：
The preparation method of selenium-enriched foliage fertilizer, concretely comprises the following steps：
1）Premix：By 20 ~ 35 parts of legume root systems, 5 ~ 10 parts of reed straws, 10 ~ 20 parts small numb seed, 10 ~ 20 portions of grape wine
Slag, 3 ~ 7 parts of Chinese medicine slags and 10 ~ 20 parts of animal wastes drying and crushings, are uniformly mixed；
2）Just stirring fermentation：In premix add 1 ~ 2 part of EM bacteria agent, after mixing with covered rearing with plastic film be sealed by fermentation 1 ~
5d, is cooled to 30~35 DEG C after fermentation；
3）Secondary agitation ferments：It will just stir and 5 ~ 10 parts of EM bacteria agents, 0.001 ~ 0.003 part of tannin and 0.02 are added in tunning
~ 0.05 part of L-（+）- ethyl tartrate, adds water and pH adjusting agent, fermentation.Fermentation temperature is 40 ~ 60 DEG C, initial pH for 6.0 ~
7.0, every 2 ~ 3d turnings once, it is 30 ~ 40% to control water content, and fermentation time is 8 ~ 20d.Fermentation vat is opened after fermentation
Temperature fall, up to tunning；
4）It is granulated：10 ~ 20 times of volume of water, are sufficiently stirred in secondary agitation tunning, filter to take filtrate, heating be concentrated to
1/10 ~ 1/6, add 1 ~ 5 part of Celastrus angulatus, 1 ~ 5 part of nimbin, 10 ~ 20 parts of oyster shell whitings, 5 ~ 10 parts of sodium selenates, 0.02 ~ 0.06 part
EDTA-Mn and 0.06 ~ 0.15 part of EDTA-Mg, dries granulation and obtains selenium-enriched foliage fertilizer after mixing.The above method is planted with pulse family
The herding such as the agricultural wastes such as thing root system, reed straw and animal wastes discarded object is raw material, realizes waste utilization, both reduced
The discharge of environmental contaminants reduces the manufacturing cost of fertilizer again；Plant in raw material is difficult to absorb by secondary fermentation big
Molecular substance is degraded to inorganic salts, a large amount of beneficial microbes and its metabolite of generation, with sodium selenate, EDTA-Mn and EDTA-
Mg is mixed into plant and provides nutriment needed for its growth, promotes its growth.And it can also be coupled with skin rattan element and nimbin
Effect, improves the toxic action of skin rattan element and nimbin to pests such as blue or green worm, ladybugs, mitigates the infringement of pests on plants.It is secondary
Tannin and L- during stirring fermentation（+）- ethyl tartrate is attached to phage surface, accelerate thalline internal ribosome, golgiosome and
The activity of mitochondria, accelerates fermentation of the EM bacteria agent to raw material.Inorganic salts and beneficial microbe content are bright in the product that fermentation obtains
It is aobvious to be higher than the prior art, and plant growth can be promoted, plant is high to its absorption rate.
Preferably, the preparation process of oyster shell whiting is：Shell is cleaned up after 0.1 ~ 0.3mol/LNaOH with clear water
8 ~ 12h is soaked in solution, takes out, neutrality is washed with distilled water to, in 2 ~ 5%H2SO48 ~ 12h is soaked in solution, is taken out, with distillation
Water washing is dried to neutrality；2 ~ 4h of supersonic oscillations in ‰ salinity solution of 20-30, drying, shell is obtained after high-temperature roasting
Powder.High-temperature roasting concretely comprises the following steps：100 ~ 120 DEG C of 5 ~ 10min of calcining；200 ~ 220 DEG C of 5 ~ 10min of calcining；400 ~ 500 DEG C of calcinings
40~60min；300 ~ 320 DEG C of 20 ~ 30min of calcining；100 ~ 120 DEG C of 10 ~ 15min of calcining.The oyster shell whiting that above-mentioned preparation method obtains
With larger mesopore volume, huge specific surface area and complexity, the pore structure of prosperity, strong to the adsorption capacity of inorganic salts,
Also there is more excellent bacteriostasis, improve the adsorption capacity of foliar fertilizer, extend its residence time on blade face, it is slow to strengthen it
The property released.
Preferably, shell is Trachyostracous mussel, tiger spot shellfish, white jade shellfish, pearl shell, daylight tellin, hundred precious spiral shells, snow mountains treasured
One kind in spiral shell, snipe skull spiral shell, long punch spiral shell, long Neptunea cumingi, acanthosphere murices, long rotation spiral shell, fancy carp spiral shell, Martin's proboscis and black tooth triton
It is or a variety of.The shell of mentioned kind has excellent adsorptivity and biocidal property according to oyster shell whiting made from the present invention program.
Preferably, oyster shell whiting is nanoscale.Above-mentioned substance particle diameter specific surface area in nanoscale is big, and adsorption capacity is good,
And easily it is absorbed and used by plants.
Compared with prior art, the advantage of the invention is that：Organic fertilizer prepared by the method for the present invention is directed to potted plant
Growth characteristic, there is provided the micro member of the moderate-element and Fe, Mn, Zn etc. such as N, P, K essential element needed for its growth, Ca, Mg, S
Element, and the growth of root system of plant can be promoted, improve absorption rate of the plant to organic fertilizer.By secondary fermentation by raw material
The macromolecular substances that plant is difficult to absorb are degraded to inorganic salts, a large amount of beneficial microbes and its metabolite of generation, with selenic acid
Sodium, EDTA-Mn and EDTA-Mg are mixed into plant and provide nutriment needed for its growth, promote its growth.And can also be with skin
Rattan element and nimbin coupling, improve the toxic action of skin rattan element and nimbin to pests such as blue or green worm, ladybugs, mitigate pest pair
The infringement of plant.Tannin and L- when secondary agitation ferments（+）- ethyl tartrate is attached to phage surface, accelerates thalline kernel
The activity of sugared body, golgiosome and mitochondria, accelerates fermentation of the EM bacteria agent to raw material.Fermenting in obtained product inorganic salts and has
Beneficial microorganism content can promote plant growth apparently higher than the prior art, and plant is high to its absorption rate.Organic fertilizer
With larger mesopore volume, huge specific surface area and complexity, the pore structure of prosperity, strong to the adsorption capacity of inorganic salts,
Also there is more excellent bacteriostasis, its residence time on blade face is grown, and slow release is good.
