Abstract
The invention discloses a method for preparing a water-soluble humic acid nitrogen and potassium fertilizer by using lignite. The method comprises the following specific steps of: crushing the lignite to be over 100-mesh; adding 1-3 percent of potassium hydroxide with purity of 99.9 percent; stirring for 10-20 minutes; uniformly mixing; controlling moisture to be 30-35 percent; hermetically piling for 7-10 days to obtain potassium humate; adding a nitrogen fertilizer and a potassium fertilizer into the potassium humate according to the proportion of nitrogen to phosphorus to potassium of 10:0:15; keeping the content of humic acid over 10 percent; stirring; uniformly mixing; and granulating to obtain a finished product, wherein the total nutrient is not less than 25 percent. The method for preparing the water-soluble humic acid nitrogen and potassium fertilizer has the advantages of simple steps, easiness in operation, rich raw materials, low cost and good economic benefit.
Description
Technical field
The invention belongs to agricultural technology field, be specifically related to a kind of preparation method of fulvo acid nitrogen potash fertilizer.
Background technology
Fulvo acid class nitrogen potash fertilizer; Its xanthohumic acid that contains can be accelerated phosphate fertilizer and move, and absorbs and the storage potassium ion, strengthens chemical combination, absorption, chelating; Xanthohumic acid has the strong impulse effect to prohormone in the crop; Can effectively improve chemical fertilizer utilization ratio, improve the absorption of crop, reduce the loss of element nitrogen, potassium element.Humic acid fertilizer in the past normally carries out humic acids to add other elements uses again behind the chemical reaction earlier; Include Ulmic acids, brown rot acid and the xanthohumic acid separated in the humic acids in this fertilizer, these compositions and Pottasium Hydroxide reaction obtain xanthohumic acid potash fertilizer solution; Again through concentrating, dry, process powder; Perhaps directly use as fertilizer additive, this method technology is loaded down with trivial details, and production cost is high.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of technology simple, operation easily, and cost is low, the effective method for preparing fulvo acid nitrogen potash fertilizer with brown coal.
In order to solve the above technical problem, the present invention is a kind of to prepare the method for fulvo acid nitrogen potash fertilizer with brown coal, said method comprising the steps of:
A, humic acids activation: the brown coal pulverizing is reached more than 100 orders, and adding purity is 99.9% Pottasium Hydroxide 1～3%, stirs 10～20 minutes, mixes, and moisture controlled is 30～35%, and sealing was stacked 7～10 days, got potassium humate;
B, according to nitrogen: the ratio of phosphorus: potassium=10:0:15 adds nitrogenous fertilizer and potash fertilizer in said potassium humate, humic acids content stirs, mixes more than 10%, granulation, finished product, i.e. fulvo acid class nitrogen potash fertilizer, total nutrient is not less than 25%.
As preferably, step a according to the invention, the content of humic acid of brown coal is not less than 25%; Said step b, nitrogenous fertilizer are urea and ammonium chloride, and potash fertilizer is Repone K; Said step b, nitrogenous fertilizer are urea and ammonium sulfate, and potash fertilizer is vitriolate of tartar.
According to the inventionly prepare the method for fulvo acid nitrogen potash fertilizer with brown coal, manufacture craft is simple, and the brown coal that humic acids content reached necessary requirement are crushed to certain fineness; Directly add sodium hydroxide and Pottasium Hydroxide inward, each composition simply reacts earlier, and sealing was preserved after 7～10 days; Humic acids is activated and obtains potassium humate, and add nitrogenous fertilizer and potash fertilizer this moment, carries out granulation; Nitrogenous fertilizer is squeezed and deliquescence in the granulation process, and the moisture that its deliquescence provides promotes humic acids and sodium hydroxide and Pottasium Hydroxide to produce reaction for the second time, and fertilizer in use; No matter be directly to be used in the soil or to dash and execute or drip irrigation; When contacting with water, accomplish institute and respond, fully the crop demand is satisfied in dissolving.The method of the invention does not need to create separately reaction conditions in the production process of whole fertilizer, but the natural loaded down with trivial details production technique of tradition of accomplishing.
Beneficial effect of the present invention: use prepared fulvo acid nitrogen potash fertilizer according to the invention, abundant raw materials is easy to get, and can provide continuously; Making method is simple, operation easily, and the reaction of humic acids closely links to each other with the production of fertilizer, use; Respectively be reflected in Industrial processes and the agricultural production process and accomplish smoothly; Do not need painstakingly remove to create reaction conditions, production cost is low, has good economic benefit.
Embodiment
Below in conjunction with embodiment the present invention is done further explain.
