Abstract
The invention discloses a production method for a rotting urea organic fertilizer. The rotting urea organic fertilizer is characterized by being prepared from, by weight, 10 parts of decomposed coal, 6-8 parts of urea, 7-8.5 parts of an organic material, 1.2-1.6 parts of auxiliaries and 7-9 parts of plant ash water. The production method comprises the steps that firstly, the plant ash water with the amount regulated by a formula is added into an extracting solution tank, when the plant ash water is heated to 20-30 DEG C, the urea is added to be stirred and dissolved, then the auxiliaries are added to be stirred and dissolved, and a composite extracting solution is prepared; the prepared extracting solution is added into a mixture of the decomposed coal and the organic material, after being stirred evenly, the mixture is added into a reaction kettle, time is kept when the mixture is heated to be 80 DEG C, the temperature of 80-90 DEG C is kept for 3 hours, discharging is conducted, and through prilling, drying and packaging, the rotting urea organic fertilizer product is obtained. The rotting urea organic fertilizer has the advantages that yield is increased by 15.9% and 22.7% through comparison of equal quantity of high-quality merchandise organic fertilizer experiments on vegetables and fruit trees, the fertilizer contains organic matter and water solubility humic acid, the nitrogen phosphorus and potassium content is high, nutrients are comprehensive, the production technology is simple, the equipment investment is small, no sewage or waste residue is discharged, the fertilizer is free of pollution and remarkable in economic benefit and social benefit.
Description
Technical field
The invention belongs to agricultural fertilizer production technical field, particularly relate to a kind of with weathered coal with add that a certain proportion of water absorption is strong and the organic materials of Nitrogen-and Phosphorus-containing potassium is as raw material, by a small amount of water, carbamide and the production method of auxiliary agent compound extracted solution dry production corruption urea fertilizer.
Background technology
nullAt present，China's humic acids produces along with country's fertilizer industry policy adjustment and the popularization and application of technique of balanced fertilizer，Achieve large development，Humic acid fertilizer produces new spectra、New varieties are continuously increased，But there is also weathered coal in current production、Brown coal、The most activated enterprise being directly produced processing " humic acids " fertilizer of the peat composed of rotten mosses，Its product nutrient content is low、Weak effect，Serious waste manpower、Financial resources and natural resources，It is negatively affected to the popularization and application of humic acid fertilizer，In humic acids produces，The humic urea complex that humic acids generates with urea reaction，Also referred to as humic acid urea，Activity because of its suppression urase，Carbamide is delayed to decompose，Reduce volatilization，Extend fertilizer efficiency，Promote the prominent functions such as root system development，Obtain the great attention of vast agrochemicals author，With water as medium，From weathered coal, humic acid urea liquid fertilizer prepared by fulvo acid is extracted in crops punching fertilising with carbamide and composite activating agent、Popularization and application in foliage fertilizer，Reported in literature existing to its mechanism of action and effect of increasing production，But with weathered coal with add the organic materials of a certain proportion of bibulous and Nitrogen-and Phosphorus-containing potassium as raw material，Use a small amount of water、Carbamide and auxiliary agent compound extracted solution dry production corruption urea organic fertilizer so far there are no report，Therefore，Develop one containing organic matter、Fulvo acid、The solid corruption urea organic fertilizer that N-P-K content is high，To promoting that the adjustment of chemical fertilizer industrial structure change and agricultural production and income are significant.
Summary of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, the production method of a kind of rotten urea fertilizer is provided, it is that by force and Nitrogen-and Phosphorus-containing potassium organic materials is as raw material, by a small amount of water, carbamide and the production method of auxiliary agent compound extracted solution dry production corruption urea organic fertilizer with the weathered coal containing humic acids total amount high (50%) and a certain proportion of water absorption of interpolation.
The technical solution used in the present invention: the production method of a kind of rotten urea fertilizer, is characterized in that being made up of the raw material of following weight portion:
Weathered coal 10 parts,
68 parts of carbamide,
Organic materials 7 8.5 parts,

Vegetation buck 79 parts；
Production method step is as follows: is first added by the vegetation buck specified by formula ratio and extracts addition carbamide stirring and dissolving when being heated to 20 30 DEG C in flow container, adds auxiliary agent stirring and dissolving, prepare compound extracted solution；Being put into by prepared extracting solution in the compound of weathered coal and organic materials again, add in reactor after stirring evenly, be heated to material temperature 80 DEG C and start timing, temperature 80 90 DEG C keeps discharging in 3 hours, through pelletize, dries, packs and i.e. obtain rotten urea organic fertilizer product.
In such scheme, described weathered coal is that Shanxi is produced containing the weathered coal breeze that humic acids total amount 62%, fineness are 100 mesh.
In such scheme, described carbamide nitrogenous 46%.
In such scheme, described auxiliary agent is the one in the potassium hydroxide of purity 85% or the sodium hydroxide of purity 99%.
In such scheme, described vegetation buck make a living thing power plant wash ash waste water, containing potassium oxide 5 6%.
In such scheme, described organic materials is tobacco powder, fineness 100 mesh, Nitrogen-and Phosphorus-containing potassium 5.5 6.13%.
The method have the benefit that the rotten urea fertilizer that the present invention is produced contains organic matter 70 80%, N P and K 12 16%, fulvo acid 17 23%, humic acids extraction rate reached 70 90%, with equivalent best buy fertilizer Experimental comparison on vegetable, fruit tree crop, volume increase 15.9% and 22.7% respectively, this fertilizer organic matter, fulvo acid, N-P-K content are high, nutrient is complete, production technology is simple, equipment investment is few, without waste water, waste sludge discharge, pollution-free, raw material resources are abundant, resource utilization is high, and economic benefit is notable with social benefit.
