Description
Technical field
The present invention relates to technical field of land improvement, more particularly to a kind of preparation method of saline-alkali land soil conditioner.
Background technology
The salinization of soil refers to that the salinity of soil bottom or underground water rises to earth's surface with capillary, after moisture evaporation, is made
Process of the salt accumulation in topsoil.The salinization of soil is a global problem, and China has a city more than nearly 100 to sit
Salt-soda soil distributed area is fallen within, these arid and semi-arid lands of North China, northwest and northeast are focused primarily upon.Agriculture plantation is because saline and alkaline
Change and cause the underproduction, it is no longer cultivated phenomena such as make large area soil resource be difficult to be fully utilized.And population base of China it is big,
Population increases soon, with the development of urbanization, is faced with the immense pressure that arable land is fallen sharply, either improves the unit in existing arable land
Area output still in a planned way reclaims wasteland and all necessarily involves salt-soda soil.
Currently, the ameliorative measure of alkaline land soil is mainly the following method：
（1）Physically improved method, mainly to the modification of soil horizon, such as ground grading, deep ploughing is suned the earth which has been ploughed up, soil moved in improve the original raises ground
Face, microcell are improved the soil and the methods of big cave site preparation, to improve soil texture, ensures the policy growth and development of cultivated plant；
（2）Chemical modifying method is mainly improved the chemical property of soil using chemical amelioration agent, on the one hand changed
Good soil texture accelerates desalinization of soil by flooding or leaching salt discharge；On the other hand change soluble-salt based component, increase base exchange capacity,
（3）Biological modification method mainly has and selects salt tolerant seeds, windproof cooling, adjusts rainwash, and tree crown evaporation is a large amount of
Moisture makes level of ground water reduce, and mitigates surface salification；The stronger green manure of plantation salt-resistance and herbage, solonchak have positive improvement
Effect；Utilize high capability of anti-salt plant；Improve the saline-alkaline tolerance of plant.
Invention content
Above-mentioned to solve the problems, such as, the purpose of the present invention is to provide a kind of preparation sides of saline-alkali land soil conditioner
Method.The preparation method of the saline-alkali land soil conditioner, it is preferable that obtained soil conditioner plays effect in alkaline land soil
And the length that can hold time.

Further, the molecular weight of the Sodium Polyacrylate is 1000000 ~ 10000000.
In addition, the ion exchange resin is hydrogen type cation exchange resin.
Separately have, the microbial bacterial agent is appointing in bush mycorrhiza agent, fixed nitrogen bacteria agent, photosynthetic bacteria microbial inoculum and growth promoting bacteria agent
One kind or combinations thereof.
Again, the preparation method of the saline-alkali land soil conditioner includes the following steps：
（1）By biogas residue in dryer drying and dehydrating, sieved with 100 mesh sieve after grinding；
（2）In step（1）Material in microbial bacterial agent is added, be uniformly mixed obtain mixed material；
（3）By step（2）Obtained mixed material carries out mist projection granulating；
（4）Secondary coating is carried out by material grain elder generation spent ion exchange resin coating, then with Sodium Polyacrylate.
The beneficial effects of the present invention are：
（1）The preparation method of saline-alkali land soil conditioner provided by the invention, obtained soil conditioner is in salt-soda soil soil
In earth play effect preferably and the length that can hold time.
（2）The saline-alkali land soil conditioner that preparation method of the present invention obtains is added with ion exchange resin, can effectively inhale
Sodium ion in attached alkaline land soil improves soil texture, promotes plant growth；
（3）The saline-alkali land soil conditioner that preparation method of the present invention obtains is added with the Sodium Polyacrylate of high molecular weight, energy
So that Zinc fractions is stablized granule, and Sodium Polyacrylate itself absorbs water, soil erosion can be improved, improves soil texture, reach increasing
The effect of production；
（4）The saline-alkali land soil conditioner that preparation method of the present invention obtains, one of raw material are selected biogas residue, are made full use of discarded
Resource turns waste into wealth, and low raw-material cost is easy to get, and is conducive to environmental protection.
