Abstract
The present invention relates to a formula of a silicon-nitrogen-phosphorus granular fertilizer. The mixture ratio of silicon powder and amide nitrogen to calcium superphosphate is 6:3:1. The formula comprises effective components of 18 to 21% of SiO2, 13.8% of CO(NH2)2 and 1.5 to 2% of P2O5. In a second formula, the mixture ratio of silicon powder and amide nitrogen to calcium superphosphate is 5:3:2, and the formula comprises effective components of 15 to 17.5 % of SiO2, 13.8% of CO(NH2)2 and 4% of P2O3. The production techniques of the two granular fertilizers are same, slag is quenched from silicon water to be dried and milled into powder, amide nitrogen is pulverized, calcium superphosphate is dried and pulverized into powder, and the three kinds of powder of raw materials are stirred uniformly by a stirrer and granulated by a granulator to be dried to form the granular fertilizer. The present invention is suitable for crops such as rice, sugarcane, reed, fruit trees, vegetables, etc., the increase in yield is obvious, and the rice is increased in yield by one time than simple application of the isometric nitrogenous fertilizer after the application of rice.
Description
The invention belongs to agricultural and go up a kind of Si-N-P granular fertilizer that uses.
Before the present invention made, according to pertinent data, the Taiwan Province of Japan, Korea, some countries of South East Asia and China used the situation of slag fertilizer and ore deposit tail fertilizer, promptly use siliceous fertilizer separately, but its fertilizer efficiency is not obvious, was difficult for being accepted by the peasant.The potassium silicate composite fertilizer that Japan utilizes flyash to produce is to add a certain amount of KOH or K in flyash
2CO
3With a spot of Mg(OH)
2Back granulation, drying and roasting forms, because Production Flow Chart is long, power consumption is big, and is uneconomical economically.
The purpose of this invention is to provide the Si-N-P granular fertilizer that a kind of flyash shrend slag that utilizes heat power plant's vertical cyclone furnace to discharge prepares, the a large amount of flyash shrend slag that utilizes the vertical cyclone furnace discharge of existing heat power plant is as the silicon raw material, add urea and calcium superphosphate and make granulated fertilizer, solve China's agricultural fertilizer problem in short supply, particularly take silicon nitrogen phosphorus in conjunction with using, play in some sense with silicon for the potassium effect.Si-N-P granular fertilizer is suitable for crop applyings such as paddy rice, reed, sugarcane, fruit tree, vegetables, grape, watermelon, has tangible effect of increasing production.
Si-N-P granular fertilizer of the present invention is:
A Si-N-P granular fertilizer, it is 6: 3: 1 flyash shrend slag by weight ratio: urea: calcium superphosphate is formed, and its effective component content is SiO in the flyash shrend slag
2Be 18-21%(weight), urea CO(NH
2)
2-N is a 13.8%(weight), the P in the calcium superphosphate
2O
5Be 1.5-2.0%(weight).
B Si-N-P granular fertilizer, it is 5: 3: 2 flyash shrend slag by weight ratio: urea: calcium superphosphate is formed, and its effective component content is SiO in the flyash shrend slag
2Be 15-17.5%(weight), urea CO(NH
2)
2-N is a 13.8%(weight), the P in the calcium superphosphate
2O
5Be 3-4%(weight).
Here calcium superphosphate is the phosphate fertilizer of this granulated fertilizer, plays the binding agent effect again.
The production technique of Si-N-P granular fertilizer is shown in process flow sheet:
I places drying oven to dry raw material A flyash shrend slag, wears into powder with ball mill, and raw material B urea is ground into powder with pulverizer, with oven dry of raw material C calcium superphosphate or seasoning, is ground into powder with pulverizer again;
II will grind and pulverize the back raw material A, raw material B, raw material C pour stirrer into and stir;
III is sprayed suitable quantity of water on the above-mentioned mixture that stirs, and sends the tablets press granulation to;
IV is with fertiliser granulates oven dry or seasoning;
The V packing of checking the weight, finished product.
Embodiment one:
The flyash shrend slag oven dry of 1, Shenyang Thermal Power Plant being discharged, ball milling becomes powder, claims its SiO
260 kilograms of the shrend ground-slag of content more than 30% are pulverized urea (nitrogenous 46%), claim 30 kilograms, and calcium superphosphate is pulverized oven dry, and it contains P
2O
5Be 12%, take by weighing 10 kilograms again as binding agent; 2, pouring the powder of above-mentioned three kinds of raw materials into stirrer stirs; 3, spray suitable quantity of water and send the spiral tablets press to or the granulation of drum-type tablets press at the above-mentioned mixture that stirs; 4, the fertilizer of making grain can obtain 100 kilograms of Si-N-P granular fertilizers through seasoning or oven dry.
Embodiment two:
Flyash shrend ground-slag, it contains SiO
2More than 30%, take by weighing 50 kilograms, urea (containing N46%) takes by weighing 30 kilograms, and the peroxophosphoric acid calcium powder (contains P
2O
514-18%) take by weighing 20 kilograms, press the technical process processing of embodiment one, can obtain 100 kilograms of Si-N-P granular fertilizers.
Application effect
Si-N-P granular fertilizer can be used as the base fertilizer of paddy rice or the use of topdressing, it is sane to use rear rice plant, drought resisting, resistant to lodging, Resistant, prevents early ageing, promotes precociously that it is heavy to increase spike number, grain number, grain, improve the paddy grade, it is than using merely the volume increase of equivalent nitrogen phosphorus fertilizer more than one one-tenth; Apple tree uses that rear blade thickens, the leaf look shinny; Have obvious preservation after watermelon is used, grape and vegetables are all had obvious effect of increasing production.
Succeeding in developing of Si-N-P granular fertilizer, a large amount of silicon Water Quenching Slag that steam power plant in all parts of the country is discharged obtain utilizing, and turn waste into wealth, turn bane into boon, alleviate environmental pollution, again for China opens up the new source of manure, increase fertilizer variety, solve China's agricultural fertilizer problem in short supply, especially the utilization of siliceous fertilizer is played with silicon in the sense for the potassium effect, solves China's potash fertilizer and lacks problem, silicon nitrogen phosphorus granulation fertilizer, its benefit is:
1, be conducive to fertilizer efficiency and play one's part to the full, do not add adhesive, silicon phosphorus and urea dressing can improve the utilization rate of N;
2, suitable silicon nitrogen ratio is transferred nitrogen with silicon, makes the crop plant such as paddy rice sane, strengthens resistance against disadvantage;
3, use this multielement synthetic fertilizer, can simplify the loaded down with trivial details operation procedure that each seed manure repeatedly gives, easy to use, save the labour.
