Abstract
A slow-release/control-release magnesium siliconesium fertilizer consists of potash feldspar 54-69wt%, limestone 15-20wt%, potassium chloride 6-18wt% and magnesium chloride 8-10wt%. The process is carried out by converting insoluble elements containing silicon, potassium, potassium and magnesium into soluble substances, heating while calcining and granulating. A high-concentration fast-effective potassium fertilizer and magnesium fertilizer are added into insoluble mineral potassium fertilizer to obtain glass silicate, and potassium and magnesium etc. nutrients are released to be absorbed by plant roots.
Description
Technical field
The invention belongs to mineral potash fertilizer production field, particularly a kind of solubility in citric acid (water-insoluble) silicon potassic-magnesian fertilizer of producing slow/controlled release.
Background technology
In the past China to utilize the sequencing of soil and fertilizer be nitrogen, phosphorus, potassium, to the eighties of last century later stage nineties, the agriculture production potassium deficiency has become more serious problem, national departments concerned comes into effect " mending the potassium engineering ", potash fertilizer is used and is drawn attention thus.The main raw material of traditional mode of production potash fertilizer is the water-soluble sylvite resource that China lacks, therefore early stage domestic required potash fertilizer mainly relies on import, mainly is Repone K and vitriolate of tartar, all belongs to chemical fertilizer, these potash fertilizer are water soluble quick-acting fertilizer, are characterized in nutrient density height (K
2O50～60%), fertilizer efficiency is fast, but this fertilizer not only easily runs off, utilization ratio is low, and its chemical property can destroy Soil structure, causes the hardening soil, Repone K also can influence the quality of multiple agricultural-food.Recent raising along with crop yield, except that lacking a large amount of potassium elements, the especially shortage of magnesium of moderate-element has appearred again, the U.S. is at the variation of China's soil nutrient, release potash magnesium sulphate fertilizer, then Israel, Germany etc. are also to the Chinese exports potassic-magnesian fertilizer, and domestic also have a manufacturer production potassic-magnesian fertilizer, and these potassic-magnesian fertilizers mainly are the mixed preparing fertilizer of quick-acting chemical fertilizer such as vitriolate of tartar, Repone K and sal epsom.The content of potassium is lower than pure potash fertilizer such as Repone K or vitriolate of tartar in the potassic-magnesian fertilizer, because replenished magnesium elements, fertilizer efficiency is better than simple potash fertilizer, and still, this potassic-magnesian fertilizer still belongs to the chemical fertilizer that is mixed, and its adverse side effect still exists.
Eighties of last century fifties is domestic to begin to develop the rich potassium felspar sand resource of producing of China and produces water-insoluble mineral potash fertilizer, the some shortcomings of available potassium chemical fertilizer have been remedied, but continuous increase along with demand such as moderate-element such as magnesium, calcium in the soil, existing mineral potash fertilizer does not still satisfy demand, and the very low (K of the content of potassium
2O only 5%), the shared market share is less, and just potash fertilizer market replenishes.
Summary of the invention
The object of the present invention is to provide a kind of slow/effect/release-controllable silica-potassic-magnesium fertilizer,, produce citric soluble silicon potassic-magnesian fertilizer so that nutritive element such as quick-dissolving potassium and magnesium in silicon, potassium and the Repone K of indissoluble in potassium felspar sand and the Wingdale, the magnesium oxide is all transformed into solubility in citric acid.
For achieving the above object, the present invention adopts following technical scheme: with potassium felspar sand and Wingdale is raw material, add Repone K and magnesium oxide, the main component ratio is potassium felspar sand 54～69%, Wingdale 15～20%, Repone K 6～18%, magnesium oxide 8～10%, forms through heating and calcining, granulation.
Production process is as follows: (1) raw material: potassium felspar sand and Wingdale are pulverized back and Repone K, the preparation of magnesium oxide according to the form below ratio; (2) will mix through homogenizing storehouse in proportion after the raw material pulverizing; (3) go up the kiln calcining: temperature is controlled at 1100～1300 ℃, 30～50 minutes time; (4) kiln discharge, be cooled to work in-process; (5) with work in-process ball mill pulverizing powdering, after granulation, become granular product.
Silicon potassic-magnesian fertilizer main raw materials in proportion table
| Raw material | Potassium felspar sand | Wingdale | Repone K | Magnesium oxide |
| Ratio | 54～69％ | 15～20％ | 6～18％ | 8～10％ |
The effective potassium content 8～15% of silicon potassic-magnesian fertilizer that this method is produced, effectively silicon-dioxide 25～35%, effectively magnesium 8～10%.
The present invention utilizes the rich potassium felspar sand resource of producing of China, on the basis that produces water-insoluble mineral potash fertilizer, the quick-acting potash fertilizer and the fertiliser containing magnesium that add high density, this silicon potassic-magnesian fertilizer belongs to the water-insoluble mineral fertilizer of slow/controlled release, basic metal such as the potassium felspar sand in the raw material, Wingdale and Repone K, magnesium oxide interact, generate the silicate of vitreous state, this silicate is also water insoluble, but be dissolved in the secreted weak acid of root system of plant, discharge nutrients such as contained potassium, magnesium, absorb for root system of plant.The silicon potassic-magnesian fertilizer that the present invention produced is direct water-soluble solubility in citric acid slow/release and release control fertilizer, compares with existing chemical potash fertilizer: have fertilizer efficiency lastingly, supply with as required, characteristics that plant recovery of nutrient is high; Compare with existing mineral potash fertilizer: effectively potassium content improves 60～300%, K
2O reaches 8～15%, and increase moderate-element magnesium (MgO8～10%), its active constituent content height, nutritive element balance, denitrogenate with phosphorus outside, contain all required nutrients of farm crop basically, comprehensive fertilizer efficiency is much better than other similar fertilizer, in agriculture production, use, can reduce rate of fertilizer application, fertilizer application frequency, reduce production costs, improve the economic benefit of agriculture production.
