Siliceous fertilizer Yi Bei world soil educational circles confirms as the 4th kind of growth elements fertilizer after nitrogen, phosphorus, potash fertilizer.It can promote
Enter nitrogen, phosphorus transports seed from stem and leaf；Crops are different to the demand of nutrient at different growth phases, and siliceous fertilizer can balance
The crop absorption to elements such as nitrogen, phosphorus, potassium.Siliceous fertilizer is again health care fertilizer, and it can be the most heavy metal-passivated, alleviates heavy metal-polluted soil dirty
Dye, improves soil alkali.Additionally, while the middle trace element that Applying silicon fertilizer is required for supply crop, it is also possible to effectively change
Kind soil environment, by there is displacement reaction, will accumulate in the poisonous and harmful ion conversions such as the ferrum in soil, aluminum and becoming non-poisonous material
Matter, reduces the poisonous and harmful element ill effect to crops in soil.
By the type of effective silicon, siliceous fertilizer can be divided into Water-soluble silicon fertilizer and solubility in citric acid siliceous fertilizer.Water-soluble silicon fertilizer, mainly with water
Soluble silica salt form exists, and mainly metso and silicic acid potassium salt, available silicon content is higher, has quick-acting, but applies
Easy leaching loss after soil, fertilizer efficiency is short；Solubility in citric acid siliceous fertilizer is mainly calsil, does not has clear and definite molecular formula and relative molecular mass,
Available silicon content is relatively low, has late effect property, and after being manured into soil, silicon release is relatively slow, and fertilizer efficiency is long.In the long run, development solubility in citric acid
The importance of siliceous fertilizer is far longer than Water-soluble silicon fertilizer.
Silicon is the second largest element of the composition earth's crust, but the silicon in soil nearly all belongs to crystalline state and unformed shape, no
Directly can be absorbed by plant.In China, if the content of effective silicon is less than 100 ppm in soil, then show that soil lacks silicon.China is yellow
River, Huai-Hai and Liaodong Peninsula soil lack the ratio of silicon and all account for 50%, and this situation in the Yangtze river basin is more serious, and its ratio can
Reach 70%, and the cultivated area that China lacks silicon the most gradually expands.If by every 667m2Applying silicon fertilizer 50kg counts, then the year of China
Need siliceous fertilizer amount to be about 3000～40,000,000 tons, but the yearly productive capacity of actually China's siliceous fertilizer is only more than 1,000,000 tons, far from

At present, China mainly with various industrial solid castoffs (such as blast furnace slag, gangue, Phosphorus Slag, ardealite etc.) and
Mineral (such as limestone, Maifanitum, potassium feldspar etc.) are that siliceous fertilizer prepared by raw material.Production technology mainly has: (1) by raw material through powder
Broken, grind, sieve and after pelletize, be directly applied to farmland；(2) utilize flyash, gangue etc. and crop material for raw material, lead to
Cross the alkali flux such as addition KOH and prepare siliceous compound organic fertilizer under conditions of heating；(3) silicon-containing material is lived through calcining
Change, cooling, be used in mixed way with other fertilizer after pelletize；(4) by silicon-containing solid garbage with other mineralizer according to a certain percentage
Mixing, calcines under given conditions and prepares；(5), after Ore roasting, after high pressure shrend, become little granule, then dry and make
Grain；(6) first roast ore, is then dissolved in product of roasting in acid solution, adds harmless medicine and carries out displacement reaction, and displacement is removed
Heavy metal, makes the effective ingredient in Ore be converted into purer inorganic salt.In industrial solid castoff and raw mineral materials often
Containing higher aluminium oxide, in activation process, aluminium oxide can be transformed into toxicity form and soluble state, especially at acid ground
In, the aluminum murder by poisoning to plant can be increased the weight of, additionally, be difficult to avoid the harmful elements such as heavy metal to exceed standard with industrial residue for raw material.
