Abstract
The method for producing flyash-Si-K fertilizer with flyash from steam power plant and shor potassium (or potassium sulfate) through mixing and roasting features that obtained fertilizer contains citric acid soluble SiO2, soluble potassium oxide and trace elements for increasing yield of crops, and resisting lodging, drought and disease.
Description
The present invention relates to a kind of fertilizer and production method thereof, particularly a kind ofly make Si-K fertilizer and production method thereof with flyash, salt lake potassium or vitriolate of tartar.
The potash fertilizer kind of producing mainly contains Repone K, vitriolate of tartar and kiln ash potash fertilizer at present.The silicate trace element fertilizer that burns till with flyash has: silicate boron fertilizer, silicate zinc fertilizer, silicate manganese fertilizer.Si-K fertilizer is the binary compound fertilizer of structure dissolubility, not only can supply with crop grand nutrition element potassium, also supplies with amount nutritive element silicon in the crop, and in addition, various trace elements such as the calcium in the flyash, magnesium, boron, zinc also can be used as nutrition and absorbed by crop.
The objective of the invention is to fully utilize the flyash of thermal power plant, utilize state-owned resource Yanyuan potassium to produce flyash-Si-K fertilizer, flyash is turned waste into wealth.
Implementation method of the present invention is: flyash and salt lake potassium (or vitriolate of tartar) are stirred, the weight percent of two kinds of materials is: flyash 70%-60%, salt lake potassium (or vitriolate of tartar) 30%-40%, optimum weight per-cent is: flyash 65%, salt lake potassium (or vitriolate of tartar) 35%, material after stirring is sent into roasting kiln, feed water vapor in the roasting kiln, make and reach air mixes coexistence with water vapor condition in the kiln, roasting 30 minutes, maturing temperature is 850 ℃～900 ℃, promptly obtains the Si-K fertilizer product behind naturally cooling.
The reaction equation of above-mentioned production process is:
Si-K fertilizer is a kind of new-type fertilizer, without any waste, also can fully utilize flyash in the production process, administers environment, turns waste into wealth.Si-K fertilizer is citric soluble binary compound fertilizer, and is water insoluble, and is dissolved in weak acid, in the plant-growth root system excretory citric acid be in harmony good can the dissolving this fertilizer, contain citric soluble silicon-dioxide SiO in the fertilizer
2Be 25%, the potassium oxide K of solubility
2O is 20%.Citric soluble SiO
2After plant absorbing, be gathered in the plant materials, during the moisture evaporation of blade face, be deposited in the epidermic cell film of leaf and stem, make cytolemma SiO
2Change, strengthened plant materials, make its intrusion that is not subject to germ, potassium ion is the most effective ion that promotes the plurality of enzymes activation, can promote photosynthesis, promotes absorption and the utilization of plant to nitrogen, and therefore, Si-K fertilizer can make crop yield.Field test proves, uses Si-K fertilizer and can make food crop volume increase 11～20%, vegetables volume increase 20～30%.
Use flyash-Si-K fertilizer edatope and crop and fruit quality are had no adverse effects, this fertilizer can be used separately, also can with nitrogen, phosphatic manure compounding application.
Claims (3)
1, a kind of flyash-Si-K fertilizer mixes the back roasting by flyash and makes with salt lake potassium, it is characterized in that: the per-cent of ingredients by weight is flyash 70%～60%, salt lake potassium (or vitriolate of tartar), 30%～40%.
2, according to the described flyash-Si-K fertilizer of claim 1, it is characterized in that: the optimum value of two kinds of raw material weight per-cents is: flyash 65%, salt lake potassium 35%.
3, the production method of the described flyash-Si-K fertilizer of a kind of claim 1, it is characterized in that: will prepare burden stirs in proportion, send into roasting kiln, feed water vapor, under the condition of water vapor and air gas mixture existence, roasting 30 minutes, maturing temperature are 850 ℃～900 ℃, then naturally cooling.
