Description
Technical field
The present invention relates to farmland soil modifying technical field, more particularly to a kind of soil conditioner and preparation method thereof.
Background technology
At present, excessive apply of the substantial amounts of industrial activity of China and farmland fertilizer causes soil acidification to aggravate, and adds
Total metalses and bio-available Zn concentration increase in the discharge of trade waste, soil, cause weight in the crops of part plantation
Overrun metal content.Therefore, Chinese Ministry of Environmental Protection in 2016 has put into effect " Soil Pollution Control action plan ", it is determined that to ensure agricultural product
Quality safety administers policy for the agricultural land soil of general thought.
Although there is various soil conditioners to can be used for improving soil property on the market now, their effect is mainly
Solve soil property acidifying, salinization, the problems such as hardened, fertilising is excessive, can not specific aim, efficiently reduce heavy metal pollution of soil pair
The negative effect of agricultural product, the quality safety of agricultural product is still difficult to be guaranteed.
The content of the invention
Based on this, it is an object of the present invention to provide a kind of soil conditioner, it can improved soil acidifying, suppression farming
Thing absorbs heavy metal, increases crop yield.
The technical solution adopted by the present invention is as follows：
A kind of soil conditioner, is made up of following raw material by weight percentage：Portland clinker 10%~40%,
Lime stone 20%~30%, dolomite 10%~30%, sepiolite 5%~15%, zeolite 1%~10%, bentonite 1%~
10%th, iron ore 3%~8%, activated carbon 1%~10%.
Wherein, Portland clinker is a kind of important industrial binder materials of China, and it is mainly generated after being reacted with water
Hydrated calcium silicate gel and calcium hydroxide, hydrated calcium silicate gel heavy metal ion have stronger adsorption capacity；Lime stone
Main component be to generate calcium oxide after calcium carbonate, calcining；The main component of dolomite is CaMg (CO3)2, oxygen is generated after calcining
Change calcium and magnesia；Sepiolite is a kind of hydrous magnesium silicate clay mineral, and its specific surface area is big, is that adsorption capacity is most strong glutinous
Native mineral；Zeolite is a kind of aluminosilicate mineral, and it has adsorptivity, is widely used as adsorbent；Bentonitic main component
It is montmorillonite, is also a kind of aluminosilicate mineral, it has adsorptivity and cation exchange property；Iron ore contain iron simple substance and
Iron compound；Activated carbon has huge specific surface area and complicated pore structure, is widely used as adsorbent.
Soil conditioner of the present invention is applied to after soil to react with water, the hydroxide that basic anhydride are generated with water
Thing such as calcium hydroxide, magnesium hydroxide can effective sweetening of the soil acidity, and increase the calcium in soil, magnesium ion, portland cement
The gel of calcium silicate of clinker generation can be passivated and adsorb the heavy metal ion in soil, and sepiolite, zeolite, bentonite, iron ore
There is suction-operated to the contents of many kinds of heavy metal ion in soil after stone, activated carbon compounding, heavy metal can be reduced and shifted to crops,
So as to reduce the absorption of crop heavy metal, improve soil physical chemistry character, promote crop growth.
Rationally, cost is low, can in advance prepare and store for future use, easy to use, energy for the formula of the soil conditioner of the present invention
Improve the heavy metal transfer in Farmland Soil Acidification, reduction soil, reduce the content of beary metal in crops, meet country to agriculture
The policy of field remediation contaminated soil, to ensureing that consumer's food security has important facilitation.
Further, the soil conditioner is made up of following raw material by weight percentage：Portland clinker
35%th, lime stone 25%, dolomite 10%, sepiolite 12%, zeolite 5%, bentonite 5%, iron ore 5%, activated carbon 3%.
Further, the soil conditioner is made up of following raw material by weight percentage：Portland clinker
25%th, lime stone 20%, dolomite 15%, sepiolite 15%, zeolite 5%, bentonite 10%, iron ore 8%, activated carbon 2%.
Further, the lime saturation factor of the Portland clinker is 0.70~0.90；Oxygen in the lime stone
The content for changing calcium is more than or equal to 45%；The content of magnesia is 15%~35% in the dolomite.
Further, the bentonite is the one or more in calcium bentonite, hydrogen matter bentonite, organobentonite；
The iron ore is the one or more in limonite, goethite, bloodstone.
The present invention also provides the preparation method of the soil conditioner described in any of the above-described, and the preparation method includes following step
Suddenly：
(1) kiln calcining is entered after crushing lime stone, dolomite, then discharging is cooled down；
(2) heating and thermal insulation by sepiolite, zeolite, bentonite, iron ore and activated carbon be broken, after grinding, then discharging is cold
But；
(3) grinding, sieving after mixing step (1), step (2) resulting material with Portland clinker, obtain described
Soil conditioner.
In step (1), generated after limestone calcination and calcium oxide and magnesia are generated after calcium oxide, dolomite calcination；Step
(2) in, heating and thermal insulation can remove the crystallization water in material, it is ensured that have enough pore structures to be used for Adsorption of Heavy Metals.
Further, step (1) is：Lime stone, dolomite are broken into after 3~5 centimetres of sizes enter kiln be fired to 600~
1000 DEG C, then discharging is cooled down.
By the block for being broken into certain size of lime stone and dolomite, be conducive to improving calcination efficiency, and limit calcining
Temperature, can ensure that lime stone is fully decomposed into calcium oxide, while ensuring that dolomite is fully decomposed into calcium oxide and magnesia.
Further, step (2) is：By sepiolite, zeolite, bentonite, iron ore and activated carbon be broken, grinding to 80~
80 DEG C~300 DEG C are heated to after 100 mesh, and is incubated 0.5~3 hour, then discharging is cooled down.
By sepiolite, zeolite, bentonite, iron ore and activated carbon be broken, grinding into the powder of certain size, be easy to uniform
Heating, while being easy to make further levigate in step (3).By limiting the scope of heating-up temperature and soaking time, on the one hand
Ensure that heating is abundant, remove the crystallization water in material, material is possessed enough pore structures, strengthen the effect of Adsorption of Heavy Metals
Really, over-heating is on the other hand avoided to destroy the crystal structure of material.
Further, step (3) is：Powder after step (1), step (2) resulting material are mixed with Portland clinker
100~200 mesh, sieving are milled to, the soil conditioner is obtained, then test, pack, be put in storage.The grinding of soil conditioner
Fineness determines that soil stickiness is lower, and soil conditioner grinding particle can be smaller with specific reference to the viscosity of soil, it is to avoid native during administration
There is hardened phenomenon in earth.
The present invention also provides the application method of the soil conditioner described in any of the above-described, and the application method includes as follows
Step：100kg~400kg soil conditioners are uniformly spread fertilizer over the fields in every mu of farmland, and after rotary tillage 1~2 time, farming is planted in interval after 2~5 days
