Abstract
The invention discloses a bio-type drip irrigation saline-alkaline soil improver and a preparation method thereof. According to the present invention, the bio-type drip irrigation saline-alkaline soil improver is prepared from amino acids, potassium fulvate, urea, monoammonium phosphate, potassium nitrate and dry powder fungicide, has good water solubility, can be used through the drip tube system, can rapidly reduce the salt content and the pH value of soil, further has effects of saline-alkaline land improving, biological activity, crop growth promoting, crop yield increasing and crop quality improving, and can effectively improve the soil fertility and increase the crop yield after the long-term use of the bio-type drip irrigation saline-alkaline soil improver, wherein the strain of the used dry powder fungicide is stable, and the spore has strong tolerance and strong adaptability.
Description
Technical field
The present invention relates to a kind of biotype drip irrigation saline-alkali soil modifying agent and preparation method, belong to soil improvement field.
Background technology
The soil salinization is the MAIN SOILS problem that China faces, and China has more than 20,000,000 hectares of salt wasteland and 670
Ten thousand hectares of salinization land, these soils can not be cultivated normally.Salt affected soil is referred to and contain in soil potassium, sodium, calcium and magnesium
Harmful salt such as chloride, sulfate, heavy carbonate.It is higher that salt affected soil is mainly characterized by pH value, containing harmful salinity, sternly
The growth of recasting about plant；Wherein sodium ion has the serious effect suppressed with poisonous plant root growth.How by simple
Method, the quick salt-soda soil salinity, recovery vegetation of reducing become the difficult problem that government and scientist face.
Jing is retrieved：Patent of invention 200910210062.4 discloses a kind of nutritional type saline-alkali soil modifier, can be used for newly-built
The improvement of oasis and secondary salinization soil with foster and apply fertilizer, belong to technical field of land improvement, the raw material that it includes：Furfural dregs 50-
70%th, decay sheep excrement 20-40%, carbamide 1-2%, Diammonium phosphate (DAP) 4-6%, potassium chloride 2-4%, zinc sulfate 0.3-0.5%, sulphuric acid
Manganese 0.3-0.5%.By raw material mixing routinely, crush, sieves the nutritional type saline-alkali soil modifier that be obtained.
Patent of invention 201110095321.0 discloses a kind of alkaline land modifying agent and preparation method, is by humic acid 5-20
Part, heavy acid calcium 15-30 parts, solid sulphuric acid 5-10 parts, farm manure 8-15 parts, trace compound 3-7 parts and bone meal 1-3 parts
Mixing granulation；By the granulation of biological bacteria 0.3-1 part；Granule obtained above is mixed, nitrogenous fertilizer 10-20 parts, phosphate fertilizer 5- is added
14 parts and potash fertilizer 3-8 parts, mix homogeneously is obtained alkaline land modifying agent.
Patent of invention 201210263257.7 is related to a kind of soil containing microorganism, inorganic nutrients, organic matter and water-retaining agent
Improvement fertilizer, is specifically designed in the salt affected soil of Shandong Province Accessories during Binzhou.Its organic matter and water-retaining agent can be effectively improved Soil structure,
Increase retention capacity of soil, so as to be that microorganism and plant growth provide better growing conditions, by selected nitrogen-fixing bacteria, photosynthetic
The complementarity and mutual benefit of bacterium, dissolving phosphor and dissolving potassium bacterium and escherichia coli in metabolism, can save the addition of inorganic fertilizer, and having can be by soil
It is difficult to be developed by the soil quality of crop utilization.Meanwhile, according to different soil constitutions, add the inorganic of different proportion and support
Point, the basic nutrient needed for crop can be met, the waste of nutrient can be reduced again.
At present, the saline soil on market mainly has 2 kinds, respectively liquid type and solid type, liquid humic acidss content
Less than 10%, solid type majority content is composited for chemical fertilizer with weathered coal humic acid, but poorly water-soluble, makes as base manure
Use improved soil.Solid type alkaline land modifying agent majority poorly water-soluble, and biological activity is low.
The content of the invention
It is an object of the present invention to provide a kind of biotype drip irrigation saline-alkali soil modifying agent and preparation method, the biotype drop
It is that, by aminoacid, fulvic acid potassium, carbamide, MAP, potassium nitrate, dry bacteria is made to fill saline-alkali soil modifying agent, the life
Thing type drip irrigation alkaline land modifying agent good water solubility, can be used by dropper system, can rapidly reduce soil salt and pH, not only
Improvement salt-soda soil, and fertilizing soil, while having biological activity, promote plant growth, improve effect of crop yield, improve and make
Article matter.
A kind of biotype drip irrigation saline-alkali soil modifying agent of the present invention, the original of the biotype drip irrigation saline-alkali soil modifying agent
Material is with percentage by weight：Aminoacid 65-70%, fulvic acid potassium 20-15%, carbamide 5-10%, MAP 2.5-5%, nitre
Sour potassium 2-4.5%, dry bacteria 0.5% is made；The dry bacteria is bacillus megaterium, bacillus licheniformis and condenses bud
Spore bacillus is 1 in mass ratio:1:3；Wherein Bacillus coagulans Bacillus coagulans ygg-1 are novel bacterial, in 2016
On July 4, in, culture presevation number was in the China typical culture collection center preservation of Hubei Wuhan Wuchang road Jia Shan Wuhan Universitys
CCTCC NO：M2016368.
The preparation method of the biotype drip irrigation saline-alkali soil modifying agent, follow these steps to carry out：
The preparation of a, dry bacteria：By bacillus megaterium, bacillus licheniformis and Bacillus coagulans according to a conventional method
Respectively through slant activation, amplification culture, centrifugal concentrating and spray drying, then in mass ratio it is 1:1:3 mixing, obtain dry powder bacterium
Agent；
B, dry bacteria 0.5% is stirred with fulvic acid potassium 20-15%, mixing for standby use；
C, by carbamide 5-10%, broken 20 mesh of MAP 2.5-5%, potassium nitrate 2-4.5% difference Jing conventional methods, then
The mixture obtained with aminoacid 65-70% and step a stirs, and is packed, that is, obtain the saline and alkaline land reform of biotype drip irrigation

It is white on peptone agar, irregularly, rough surface.Gram-positive, produces spore.By the 16S rRNA sequences of the bacterium
Compare in American National Biotechnology Information center (NCBI) data base BLAST, be 99% with the homology of Bacillus coagulans,
Jing API50CHB test kits (bioMerieux, France) identifies that the bacterium is 99.5% with the similarity of Bacillus coagulans, because
This judges the bacterium as Bacillus coagulans.Bacterial strain ygg-1 and Bacillus coagulans ATCC 7050 have 99.1% identical
16SrDNA sequences homology；DNA-DNA hybridization values are respectively 66.7%, and less than 70%, this defines the hybridization value of novel species.
Based on the phenotype of bacterium ygg-1, Physiology and biochemistry, genotype comparative analysiss show that bacterium ygg-1 is a new bacterium of Bacillus coagulans
Kind.
