Abstract
The invention relates to a fertilizer producing method and particularly relates to a method for producing liquid silicon-potassium fertilizer. The method comprises the following steps of: melting: melting potassium bicarbonate and silicon dioxide in an electric melting furnace in a closed environment under the condition that furnace temperature is controlled between 1200-1500 DEG C, wherein the molar ratio of potassium bicarbonate to silicon dioxide is 2:1-3:1; dissolving, i.e., adding deionized water in melted material, dissolving the melted material and adjusting solution modulus to 2.3-2.5; and filtering, i.e., filtering the dissolved solution to obtain liquid potassium silicate and carrying out sub-packaging, thereby directly obtaining the liquid potassium silicate fertilizer. According to the method, the water-soluble potassium silicate is prepared by the reaction of potassium bicarbonate and silicon dioxide, only the furnace temperature needs to be controlled during the process and almost no extra step is needed in the whole process, so that the production time is saved, the pollution is reduced, the whole production technology is environment-friendly, various types of pollution are avoided and the produced product contains few impurities.
Description
Technical field
The present invention relates to a kind of fertilizer production method, especially a kind of method of producing the liquid silicon potassic fertilizer.
Background technology
Two kinds of very important elements are arranged in fertilizer, and silicon and potassium, silicon are one of important nutritive elements of plant materials composition, and siliceous fertilizer is conducive to improve the photosynthesis of crop; Siliceous fertilizer can increase the physical strength of crop stalk, improves lodging tolerance; Siliceous fertilizer can improve crop to the resistibility of disease and pest, reduces the generation of various disease and pests; Siliceous fertilizer can make does air permeability enhancing in object, can prevent root system to rot and early ageing; Siliceous fertilizer can strengthen the drought resisting, hot-dry wind tolerance of crop, the anti-adversity ability such as cold-resistant; Siliceous fertilizer can strengthen the Pollen Activity of melon or fruit type crops, improves setting ratio; Siliceous fertilizer can improve the utilization ratio of phosphate fertilizer, regulates the Balance Absorption of nitrogen phosphorus potassium; Siliceous fertilizer can be improved soil, promotes fertilizer to decompose, and suppresses the soil germ and alleviates heavy metal contamination; Siliceous fertilizer is quality fertilizer, can obviously improve quality of agricultural product, prolongs storage period.
And the effect of potassium is as follows:
Promoting the activation of enzyme, is potassium one of most important function in growing process to the activation of enzyme, has now found that potassium is the activator of 60 plurality of enzymes.Therefore potassium is relevant with the many metabolic processes in plant materials, synthetic etc. as: photosynthesis, respiration, carbohydrate, fat, protein.Can promote the transportation of photosynthesis and its product: 1. improve photosynthetic efficiency; 2. regulate stomatal movement, control the turnover of CO2 and water; 3. promote the synthetic of carbohydrate, accelerate the transportation of photosynthate.Promote the synthetic of protein, the picked-up of the key component NO3 of promotion protein synthesis and transportation also participate among the process of protein synthesis.Strengthen the resistance of plant: 1. potassium can make and do soluble amino acid and monose minimizing in object, and Mierocrystalline cellulose increases, the cell walls thickening; 2. produce osmotic pressure gradient in the crop root accumulation and can strengthen moisture absorption; 3. arid the time can make the crop stomatal closure to prevent water loss.Potassium is Quality Element, can improve output and improve quality: 1. improve the fat of food crop protein content, oil crops and the sugar content of palmitic acid content, potato class and sugar crop; 2. increase staple length, intensity, the fineness of fibre crops such as cotton etc.; 3. adjust the sugar-acid ratio of fruit, increase its Vc content; 4. improve shape, size, color and luster and the local flavor of fruit and vegetable, strengthen its keeping quality.Potassium can promote leguminous crop early to tie root nodule, improves nitrogen fixing capacity.Therefore the Si-K fertilizer material is a kind of very important fertilizer.
The Si-K fertilizer that uses on agricultural in prior art is that the slag that utilizes steel-making to produce is used as Si-K fertilizer basically, but due to the silicon in slag and potassium owing to all being insoluble in water, so it is all very low to absorb efficient, poor effect in actual production.The company that has in addition also adopts wet method to come the production water-soluble potassium silicate, utilize the silicon gel of water glass and nitric acid reaction system after the deionization rinsing, add the nitric acid acidifying and purify, rinsing is the pure silicon dioxide of the rear system of neutrality dehydration extremely, then reacts with potassium hydroxide the potassium silicate of making.The method is produced Si-K fertilizer equipment factory building seriously corroded, and environmental pollution is serious, and waste water is many.
Summary of the invention
The object of the invention is to, a kind of method that production time is short, reduce the production liquid silicon potassic fertilizer that pollutes is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of producing the liquid silicon potassic fertilizer, and production method is as follows:
The first step: melting, adopt electric smelter, with saleratus and silicon-dioxide in molar ratio 2:1-3:1 put into electric smelter, under closed environment, Control for Kiln Temperature is carried out melting between 1200 ℃-1500 ℃;
Second step: dissolving, add deionized water to dissolve in the material after melting, the regulator solution modulus is to 2.3-2.5;
The 3rd step: filter, the solution after dissolving is filtered, obtain liquid silicic acid potassium.
The further setting of the present invention is: during melting, saleratus and silicon-dioxide are 2.5:1 in molar ratio.
The further setting of the present invention is: during melting, furnace temperature is 1400 ℃.
Aforesaid method adopts saleratus and silicon dioxde reaction to make water miscible potassium silicate, in this process, only needing to control furnace temperature gets final product, almost whole process does not need too many extra step, thereby saved the production time, reduced pollution, the relatively environmental protection of whole production technique, avoided various pollutions, the product of producing is seldom impure.
Embodiment
A kind of method of producing the liquid silicon potassic fertilizer of the present invention, production method is as follows:
The first step: melting, adopt electric smelter, with saleratus and silicon-dioxide in molar ratio the common ratio of 2.5:1(can be 2:1 or 3:1) put into electric smelter, under closed environment, Control for Kiln Temperature is carried out melting at 1400 ℃; Wherein furnace temperature can be also 1200 ℃ or 1500 ℃.
Second step: dissolving, add deionized water to dissolve in the material after melting, the regulator solution modulus is to 2.3-2.5;
The 3rd step: filter, the solution after dissolving is filtered, obtain liquid silicic acid potassium, then directly carry out packing, just can obtain being directly used in the liquid silicic acid potassic fertilizer of agricultural.
The saleratus that adopts in the present invention and silicon-dioxide are all high-purity, and the raw material that purity is high can reduce the generation of impurity, and the quality of finished product and purity are also very high.
Obviously, above-described embodiment be only for explanation clearly do for example, and be not restriction to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being extended out thus or change still are in protection scope of the present invention.
