Abstract
The invention discloses a high-concentration suspension type liquid compound fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: (15 to 25 parts of ammonium phosphor nitrate and 10 to 25 parts of carbamide) or 10 to 20 parts of UAN (urea and ammonium nitrate), 5 to 20 parts of sylvite fertilizer, 15 to 30 parts of monopotassium phosphate, 0 to 20 parts of phosphate fertilizer, 7 to 12 parts of suspending agent, (4 to 8 parts of zinc sulfate, 2 to 6 parts of manganese sulfate and 0 to 6 parts of boric acid) or 8 to 12 parts of potassium fulvate, and 15 to 19 parts of water. A preparation method comprises the following steps of dissolving a nitrogen fertilizer and a phosphate fertilizer in an agitator; adding the suspending agent and the monopotassium phosphate; after stirring until the materials are completely dissolved, sequentially adding the potassium fertilizer, salts of secondary elements and trace elements, or potassium fulvate, and a plant growth regulator, wherein after one raw material is added and stirred until the material is fully dissolved, the other raw material is added; after the mixture is conveyed by a pump to a colloid grinder to be ground, conveying the finished product to be filled and stored. The compound fertilizer is high in stability and uniformity, quickly absorbed by crops and high in nutrition utilization rate. A ternary liquid fertilizer which contains the trace elements is provided, and precision fertilization is facilitated.
Description
Technical field
The present invention relates to a kind of liquid fertilizer, is the ternary suspension type liquid compound fertilizer containing trace element specifically.
Background technology
Along with country advocates the water-saving policy of water-fertilizer integral and the development of modern greenhouse agriculture, traditional composite fertilizer because of its melt that speed is slow, insolubles and harmful ion is many, chemical fertilizer utilization ratio is low, already can not meet the needs of agriculture production.And each component be combined with each other in high-concentration suspension type liquid composite fertilizer, define a stable system, nutrition content is high, even concentration, nutrition contained in each fertilizer in the same batch of product produced is completely the same, balanced in nutrition, effect stability, absorption rate improve more than 2 times than solid fertilizer, safer, more green, more environmental protection, dock with water-fertilizer integral perfection, wide market is the main force in Chinese following fertilizer market.
High-concentration suspension type liquid composite fertilizer is the fluid composite fertilizer being added with suspension agent.Have the following advantages as a kind of novel efficient compound fertilizer:
1, production cost is relatively low, and equipment is simple, less investment.
2, producing, use, transport in there will not be dust, smog, pollute few.
3, there is not moisture absorption and agglomeration problems in product.
4, can with sterilant, sterilant, herbicide mixture, and to mix.
5, segregation can not be produced in accumulating.
6, foliage-spray, Sui Shuichong can execute, also can spray, drip irrigation or pouring, easy to use, save time, saving of labor, produce effects fast.
7, raw material is easy to get, and greatly reduces costs.
8, the relative clear liquid fertilizer of nutrient content can increase substantially.
As can be seen here, the crop production of high-concentration suspension type liquid fertilizer to China has important promoter action.
The Liquid Fertilizer provided in the market is all unitary or binary fertilizer, ternary liquid fertilizer is little, and rarer containing micro-ternary liquid fertilizer, and the high-quality liquid fertilizer that peasant uses now is nearly all external import, price is very expensive, adds peasant burden.
Summary of the invention
The object of the invention is to the deficiency overcoming original unitary, binary fertilizer, provide a kind of high-concentration suspension type liquid composite fertilizer and preparation method thereof, this fertilizer not only concentration is high, homogeneity and suspension fine.
This Liquid Fertilizer contains: nitrogen, phosphorus, potassium and part middle and trace element, organic matter etc. can meet crop growth needs, can according to the regulation of fertilizer requirement of crop, according to the actual crop performance situation in field and the factor such as soil regime, target output, understand different fertilizer crop to its utilization ratio, accurately apply optimum proportion and consumption, can Tree Precise Fertilization be reached.Reach the fertile volume increase of joint, object that production cost, soil protection environment are improved the soil, reduced in fat-reducing high-quality, fat-reducing.
Technical scheme of the present invention is as follows:
A kind of high-concentration suspension type liquid composite fertilizer, it is made up of the raw material of following weight parts:
(15 ~ 25 parts, ammonium nitrate phosphorus and 10 ~ 25 parts, urea) or UAN10 ~ 20 part, sylvite chemical fertilizer 5 ~ 20 parts, potassium primary phosphate 15 ~ 30 parts, phosphoric acid salt chemical fertilizer 0 ~ 20 part, suspension agent 7 ~ 12 parts, (4 ~ 8 parts, zinc sulfate and manganous sulfate 2 ~ 6 parts and boric acid 0 ~ 6 part) or potassium fulvate 8 ~ 12 parts, 15 ~ 19 parts, water.
The parts by weight of the preferred version of said ratio are:
The preparation method of described high-concentration suspension type liquid fertilizer is made up of following steps:
22 parts, ammonium nitrate phosphorus, 20 parts, urea, potassium sulfate 8 parts, potassium primary phosphate 15 parts, suspension agent 8 parts, 4 parts, zinc sulfate, boric acid 6 parts, 17 parts, water.
Above-mentioned formula also adds plant-growth regulator 0.1 ~ 0.2 part.
Above-mentioned sylvite chemical fertilizer is saltpetre or Repone K or potassium sulfate.
Above-mentioned phosphoric acid salt chemical fertilizer is monoammonium phosphate or diammonium phosphate.
A, by above-mentioned formula, as water, UAN added stirring tank with UAN, as with ammonium nitrate phosphorus and urea, first add water stirring tank, then added by urea and dissolve, and adds ammonium nitrate phosphorus and carry out stirring and dissolving after entirely molten, add phosphoric acid salt chemical fertilizer again, stir, after entirely molten, stir 5 minutes again;
The liquid of B, step 1 adds suspension agent and potassium primary phosphate by above-mentioned formula, stir entirely molten after, then stir 10 ~ 15 minutes;
C, add sylvite chemical fertilizer successively, the salt of middle and trace element or potassium fulvate, plant-growth regulator, often add a kind of after fully stir even dissolving after add another component again;
D, all component add rear stirring 10 ~ 15 minutes;
E, carry out levigate by the liquid pump delivery of step D to the levigate machine of colloid, fineness can be carried out slightly according to using method, fine control, and levigate granularity is 2 ~ 6 microns;
F, levigate after product pump delivery store to finished product storage tank, also can deliver to and respectively add fertile website and sell by direct special train.
Note: will regularly use air compressor stirred under pressure during product standing storage, prevent product layering.
The proportionings such as described nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and trace element can be determined according to routine techniques.
The using method of high-concentration suspension type compound manure of the present invention is:
Suspension type fertilizer is placed and is had demixing phenomenon too for a long time, and complete before using after shaking up and dissolve, per kilogram suspension type fertilizer is watered about 200 kilograms, drenches in crop root after stirring.Drench a clear water after vegetables have been drenched when using fertilizer again, the solution on blade is washed away.Foliage fertilizer can be made through levigate fertilizer, spray fertilizer, drip irrigation fertilizer, slight irrigation be fertile, also can rush and execute.Convenient, fast, the dark welcome by vast farmers.
The invention has the advantages that: the present invention have selected good suspension agent, and determines proportioning, obtained suspension type compound manure can obtain good stability and homogeneity.Crop is fast, and plant recovery of nutrient is high.The ternary liquid provided containing trace element is fertile, solves the technical barrier that trace element uses with fertilizer, for crop provides grow required macroelement and middle and trace element nutrient simultaneously.The nutritional deficiency symptom occurred in process of crop growth can be solved, filled up domestic blank.
