Description
Technical field
The present invention relates to vegetable fertilizer and soil improvement field, a kind of compound siliceous fertilizer for nursing one's health acid soil is specifically related to
And preparation method thereof.
Background technology
Because the acid deposition of industrial activity exacerbates the process of the regional self-souring of south China so that southern certain areas
Soil acidification is even more serious, and heavy metal in soil activity is improved, and causes the pollution of heavy metal-polluted soil to aggravate, grain security is chosen
War.
Siliceous fertilizer can improve crop resistance and resistant to lodging as a kind of alkaline fertilizer, improve agricultural output, improve agricultural production
Product quality, can also improve the physicochemical property of acid soil.Exogenous Silicon is added in acid soil can increase soil heavy metal
Absorption, and then the validity of heavy metal is reduced, alleviate the murder by poisoning of heavy metal on plants, and change the form of heavy metal in plant
Distribution, influences its activity and transfer ability.
The siliceous fertilizer sold in the market is essentially divided into two major classes, solid siliceous fertilizer and liquid silicon fertilizer.The master of solid siliceous fertilizer
Want composition be Iron-ore Slag crushed material and blast furnace slag, flyash etc., patent CN200310105447.7 introduce one kind gangue or
Flyash produces the production method of siliceous fertilizer with black liquid；Patent 201610095703.6；But utilize solid made from slag etc.
Siliceous fertilizer, available silicon content is low, and crop assimilation effect is very poor, and irrational long-term use can hardened soil.Patent
CN201510511638.6 introduces a kind of preparation method of liquid silicon fertilizer, and the nanometer grade silica mainly applied, its cost is high,
The main component of current liquid silicon fertilizer is organic chelated silicon, because expensive popularization and application are restricted.
The water-insoluble silicon resource of China is but extremely abundant, there is huge resources advantage, is the advantage for developing siliceous fertilizer.
Therefore, the key for preparing siliceous fertilizer using slightly solubility siliceous mineral is technology.Contain K in K-feldspar K [AlSi3O8]2O and SiO2
80% or so, it is that a kind of potential crop fertilizer is former also containing a variety of elements beneficial to crops such as Fe, Ca, Cu, Mg, Zn
Material.
Therefore, China can not only adequately and reasonably be improved using potash feldspar ore resource, the utilization rate of the insoluble silicon ore deposit of raising
Soil lacks the phenomenon of silicon；And the elements such as useful crop plants grow in potassium feldspar K, Ca, Zn, Cu, Fe can be made full use of, improve grain
Yield and mineral products utilization rate are eaten, therefore, a kind of it is proposed that compound siliceous fertilizer for nursing one's health acid soil and preparation method thereof.
The content of the invention
The main object of the present invention is to provide a kind of compound siliceous fertilizer for nursing one's health acid soil and preparation method thereof, former to siliceous fertilizer
Material is reasonably matched, and reaches regulation soil acidification degree, the effect that reduction heavy metals in farmland is poisoned.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of compound siliceous fertilizer for nursing one's health acid soil,
