Description
Technical field
The present invention relates to soil improvement field, more particularly to a kind of composite soil modifier suitable for saline-alkali soil and its
Preparation method.
Background technology
Saline-alkali soil is the class soil types being widely distributed on the earth, is important land resource.With population
Increasingly expand, gradually decreasing of tilling the land, promote people that notice is transferred in the salt-soda soil of large stretch of distribution.Reasonably open
Hair utilizes salt-soda soil, and it is cultivable soil to be converted into, and can not only improve total output of grain, alleviates crisis in food, also
Green coverage can be expanded, improved the ecological environment.
The salination process of soil includes salinization, two different processes of alkalization：Salinization refer to various salts such as chlorate,
The cumulative process in soil such as sulfate or nitrate so that soil is in gradually alkalescence, when these salts are accumulated in soil
To certain amount, can endanger the growth of plant is, soil salinity characters can occur；Alkalizing, this refers to that sodium ion enters in soil colloid
So as to become the process of absorbing complex, it is that in the presence of alkaline salt, pH in soil is raised, calcium, magnesium ion
Solubility declines so that soil cationic composition is changed into sodium ion and has comparative advantage, and soil more easily absorbs sodium and alkalizes.
The method of traditional improvement saline-alkali soil has：Irrigation and water conservancy measure, agricultural measures, biological control measure, chemical modifying measure
And cultivate salt-resistant varieties etc..Irrigation and water conservancy measure is adjusted using modes such as gutter drainage, drainage by shaft wells, buried drain or the desalinization of soil by flooding or leaching
Salt content in section soil.Agricultural measures be mainly level land, crop rotation, the method such as intercropping and applying organic manure change
Good soil, is typically carried out with water resources industry collocation.Biological control measure has the sides such as green manuring, afforestation or plantation saline alkali tolerant plant
Method, biological control measure is a kind of method of more effective improved soil.Chemical modifying mode is changed by directly applying soil
Good dose of method improves saline-alkali soil, and the method can be obviously improved saline-alkali soil physicochemical property, significantly improve crop yield
Chinese patent CN201210307524.6 discloses a kind of saline-alkali land soil conditioner and preparation method thereof, raw material group
Part in parts by weight, soil conditioner contain 3-8 parts of rare earth silicon-calcium mineral matter, citric acid 1-3 parts, poly 0.6-2 parts,
The raw material dosage of above-mentioned steps offer is sequentially added by stirring, mixing, is prepared.The saline-alkali land soil conditioner of the invention
Applied in plant growth early stage, desalting effect significantly, can effectively reduce influence of the salt damage to plant emergence, answered with extensive
With value.
The content of the invention
It is an object of the invention to provide a kind of composite soil modifier suitable for saline-alkali soil, the soil conditioner raw material into
This is low, prevented from caking, it is easy to sheds uniform, improvement efficiency high, and can increase soil fertility, is conducive to the plantation of crops.
It is a further object of the present invention to provide the preparation method that this is applied to the composite soil modifier of saline-alkali soil.
To achieve the above object, the present invention uses following technical scheme：
A kind of preparation method of composite soil modifier suitable for saline-alkali soil, comprises the following steps：

In mixture, continue to stir 3-4h, the sodium alginate and the mixed aqueous solution of gelatin being added thereto to afterwards after high-temperature sterilization are stirred
After mixing 30min, 12-24h is stood, be tuned into water content, microbial bacterial agent is obtained；
(2) waste straw is crushed, after drying, is sealed in heatproof container, in electric arc furnaces, in 500-630 DEG C of condition
Lower calcining 4-5h, afterwards cooling is drawn off, and biomass carbon dust is obtained；
(3) microbial bacterial agent, biomass carbon dust and desulfurization gypsum powder are mixed, grinding, is obtained after sieving described compound
Soil conditioner.
Preferably, in terms of parts by weight, the usage amount of each raw material is in the microbial bacterial agent:Peat 30-60 parts, discard
Stalk powder 50-80 parts, sodium alginate 10-18 parts, gelatin 2-7 parts, microbial fermentation solution 300mL/Kg.
Preferably, effective bacterium is Methylotrophic bacillus, streptomyces lydicus, lactic acid chain in the microbial fermentation solution
One or more mixture in coccus or azotobacter chroococcum, effective bacterial content is more than 6 × 108/mL。
Preferably, water content is 10%-30% in the microbial bacterial agent.
Preferably, the content of each component is in the soil conditioner, in terms of parts by weight, microbial bacterial agent 10-30 parts,

Preferably, the waste straw is wheat stalk, maize straw, rice straw, cotton stalk, soybean stalk, cotton
One or more mixture in chopped straw stalk, bagasse or lichee branches and leaves.
Preferably, the mesh number of sieving is 300-400 mesh in the step (3).
A kind of composite soil modifier suitable for saline-alkali soil, is prepared from by above method.
The invention has the advantages that, it is carrier to use peat and the rotten treated waste straw powder of heap, preparation
Microbial germ powder, can be greatly cost-effective, reduces cost of material, and can provide enough nutritional ingredients for microorganism.
Again by after sodium alginate and gelatin embedding, improve the survival volume of the microorganism in microbial germ powder, it is possible to be microorganism
Offer is effectively protected.Microbial germ powder is applied in saline-alkali soil, can improve soil while soil function is improved
Fertility, can also provide resistance against diseases for the crop of plantation.Additionally, the soil conditioner uses discarded stalk by after calcining
Obtained carbon dust is additive, after mixing with desulfurization gypsum powder, can effectively improve the defect of land plaster easily caking, is conducive to
Uniform, the efficiency of raising soil improvement is shed, and fertility can be increased for saline-alkali soil.
