The liquid potassium dihydrogen phosphate fertilizer belongs to a fertilizer prepared from the following raw materials: phosphorus pentoxide, potassium hydroxide, nitrogen, rare earth nitrate used as a fertilizer, disodium ethylenediamine tetraacetic acid, an adhesive agent, a penetrating agent, ferrous sulfate heptahydrate, copper sulfate, zinc sulphate, manganese sulphate, boracic acid and ammonium molybdate. The liquid potassium dihydrogen phosphate fertilizer of the present invention has the properties of yellowish liquid, homogeneous concentration and stable solution, and the content of phosphorus and potassium provided by the liquid potassium dihydrogen phosphate fertilizer reaches about 16 to 32, which not only ensures the requirement of plants for phosphorus and kalium, but also prevents the crystallization sedimentation of phosphorus and kalium; by using the liquid potassium phosphate fertilizer of the present invention, the requirement of crops for nutrient compositions for every growth period can be met to help the growing development of plants, and the liquid potassium phosphate fertilizer has the characteristics of convenient use and wide application range; the liquid potassium phosphate fertilizer has the positive functions of improving the soil structure and raising the utilization rate of a fertilizer; the present invention has the advantages of simple production process, little investment for equipment and the low cost of a product made.
Description
Technical field
The present invention relates to a kind of liquid potassium dihydrogen phosphate and production technique thereof.
Background technology
Potassium primary phosphate provides potassium and phosphorus two class growth elements because of it can be plant growth, thereby be subjected to friend's peasant welcome deeply always, but existing potassium dihydrogen phosphate mostly is powder product, it has following shortcoming: 1) powder product generally is now with the current, be subjected to the influence of solvent temperature and dissolution time, if solvent temperature is low excessively, dissolution time is short, then the effective constituent in the fertilizer is difficult to dissolving, thereby influences fertilizer utilization ratio; 2) the non-solvent components in the solution is easy to stop up mister head; 3) powder product complex process, facility investment is big, and the productive expense height causes the product cost height.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of required various nutritive ingredients of plant growth, liquid potassium dihydrogen phosphate that production technique is simple, easy to use and with low cost of being rich in is provided;
Another object of the present invention provides a kind of production technique of liquid potassium dihydrogen phosphate.
Technical scheme of the present invention is:
A kind of liquid potassium dihydrogen phosphate is the fertilizer by the preparation of following weight proportion raw material

The total nitrogen content 2.0-2.5 of above-mentioned fertilizer;
The weight proportion of described sodium onitrophenol and 5-p-nitrophenol sodium is 1: 1;
A kind of processing method for preparing the liquid potassium dihydrogen phosphate of claim 1 may further comprise the steps:
A. with potassium hydroxide neutralization while flowing in a horizontal stainless steel reactor of 85% industrial phosphoric acid and 90%;
B. circulation cooling makes reacting liquid temperature reduce to 50-60 ℃, adjusts between the PH to 5-5.5;
C. reaction solution is squeezed in the retort, be cooled to 38-42 ℃, add complexing agent disodium ethylene diamine tetraacetate, trace element: ferrous sulfate, copper sulfate, zinc sulfate, manganous sulfate, boric acid, ammonium molybdate, the mixture, suspension agent carboxymethyl cellulose and the agricultural rare earth nitrate that add permeate agent sodium onitrophenol and 5-p-nitrophenol sodium, fully stir, be finished product.
Weight proportion provided by the present invention can be adjusted at the required Different Nutrition composition of different growing stages according to various crops.
Liquid potassium dihydrogen phosphate of the present invention is little yellow liquid, and its concentration is even, and is solution-stabilized, and phosphorus that is provided and potassium content reach about 16-32, has promptly guaranteed the needs of plant to phosphorus, potassium, has prevented its crystalline deposit again; Use liquid potassium dihydrogen phosphate of the present invention, can satisfy the needs of crop nutrition in each in vegetative period, promote growth and development of plant, easy to use, wide accommodation is for the structure of improving the soil, improve fertilizer utilization ratio positive effect is arranged; Production technique of the present invention is simple, and facility investment is little, the low cost product of manufacturing.
