The humic acid organic-inorganic compound fertilizer comprises, by weight, 20-45 parts of melting urea, 10-15 parts of urea, 8.5-30 parts of potassium chloride, 10-20 parts of ammonium chloride, 10-40 parts of monoammonium phosphate, 3-9.5 parts of bentonite and 0.5-7 parts of humate. The humic acid organic-inorganic compound fertilizer and the production process thereof have the advantages of being low in investment and operating cost, simple in process and good in fertilizer efficiency.
Description
Technical field
The invention belongs to the compound fertilizer production technology field, be specifically related to a kind of less investment, technology is simple, low humic acid organic and inorganic compound fertilizer and the production technique thereof with good fertilizer efficiency of running cost.
Background technology
Along with the increase in demand of China to grain-production; The country chemical fertilizer production and use quantity also in continuous increase; Application fertilizer has play a part important to the development of agriculture prodn, but along with the increase of applying quantity of chemical fertilizer, throws fertile cost and improve; Problems such as chemical fertilizer utilization ratio reduction reflect gradually, simultaneously excessively use the primary pollution source that chemical fertilizer has become the rural area.Current China utilization rate of nitrogen fertilizer is 30-50%, and phosphate fertilizer utilization efficiency is 10-20%, and potassium utilization rate is 50-70%; And humic acids (HA) is one type of unbodied net(high)polymer organic substance; With nitrogen, phosphorus, the composite composite organic-inorganic fertilizer of processing of potassium element, the soil microorganisms speed of growth is increased, cause the organonitrogen mineralization velocity to be accelerated; The volatilization that reduces nitrogen is run off, and the content of the quick-acting nitrogen of soil is increased; Humic acids has provide protection to rapid available phosphorus, reduces soil to quick-acting phosphorus fixations, promotes the absorption of crop root to phosphorus; The acid functional group of humic acids can absorb and store potassium ion; Prevent in the strong soil of sandy soil and leaching property, to lose with current, to potassic silicate, mineral substance such as potassium felspar sand have corrosion; Promote the content of soil available potassium; Humic acids is manured into soil and can makes looseness of soil in addition, promotes root system of plant to absorb moisture, and soil humidity and water evaporation rate are had stabilization; The free humic acids can promote the contraction of plant leaf surface pore simultaneously, reduces the forfeiture of moisture; Humic acids also can improve the structure and the quality of soil, thereby improves the ventilation property of soil, activating soil nutrient.It joins the decomposition rate that can delay nitrogen in the composite fertilizer, to improve fertilizer utilization ratio.And current China humic-acid kind composite fertilizer have can't process coarse, can't suitability for industrialized production, high, the complex manufacturing technology of investment, be difficult for dissolving and the lower shortcoming of humic acids content.
Summary of the invention
The objective of the invention is to overcome defective of the prior art and provide a kind of less investment, technology simple, be convenient to dissolving, low humic acid organic and inorganic compound fertilizer and the production technique thereof with good fertilizer efficiency of running cost.
The objective of the invention is to realize like this: the present invention is formulated according to parts by weight by following raw material: fusing urea 20-45 part, urea 10-15 part, Repone K 8.5-30 part, ammonium chloride 10-20 part, monoammonium phosphate 10-40 part, wilkinite 3-9.5 part and humate 0.5-7 part.
A kind of production technique of humic acid organic and inorganic compound fertilizer, its step is following:
One, at first close first baiting valve, with urea, Repone K, ammonium chloride, monoammonium phosphate, wilkinite and humate are put into first feed bin, and the material in first feed bin is squeezed in second feed bin through the powder pump;
Two, first baiting valve and first pressure-balance valve are opened, the material in the described step 1 in second feed bin gets in first material pot, treat that material is filled first material pot after, close first baiting valve and first pressure-balance valve;
Three, first back-up valve is opened; Described first material pot links to each other with delivery air chamber through first back-up valve; When being raised to 0.15MPa with the pressure in first material pot, described delivery air chamber closes first back-up valve; Open second baiting valve, the material of first material pot is got in the terrium quid batch can;
Four, be full of material in the terrium quid batch can in the described step 3; Close second baiting valve; First pressure-balance valve and second pressure-balance valve; Open second back-up valve and the 3rd baiting valve, behind terrium quid batch can pressurization 0.15MPa, constantly in the terrium quid batch can, pressurize, the terrium quid batch can is flowed out through the 3rd baiting valve through delivery air chamber;
Five, get in the urea soln pipeline through the effusive material of the 3rd baiting valve in the described step 4 and mix with fusing urea;
Six, described mixed material gets in the granulating system of composite fertilizer's production system, after dehumidification system, screening system, cooling system, baggage systems and packaging system, finished product;
Seven, when the material in the terrium quid batch can flows out 1/2; First baiting valve and first pressure-balance valve are opened; Material in the described step 1 in second feed bin gets in first material pot; After treating that material is filled first material pot, close first baiting valve and first pressure-balance valve, be stored in material in first material pot this moment;
Eight, when the material in the terrium quid batch can flows out 2/3, when opening first back-up valve and making pressure in first material pot be raised to 0.15MPa, close first back-up valve, open second baiting valve, the material in first material pot gets in the terrium quid batch can;
Nine, after above-mentioned steps eight is accomplished, again according to step 4 to step 8 cyclic production.
The reaction of humate and urea is the reaction that is in molten state at urea among the present invention, and actual is reaction with urine.Extremely complicated reaction takes place in humate and urea, and carboxyl, phenolic hydroxyl group and urea molecule form a large amount of hydrogen bonds and/or complex coordination key; Hydroxyl and urea generation free radical reaction; Main and the urea carboxamido-group generation nucleophilic addition formation C=N key of carbonyl (aldehyde) base; Quinonyl is participated in reaction with radical part form, forms ionic linkage or covalent linkage.These keys all have higher chemicalstability, and this is that humic acid urea has higher nitrogen use efficiency and the one of the main reasons that prolongs fertilizer efficiency period in agricultural application.Wilkinite is used for the sticker of composite fertilizer; Urea is for composite fertilizer provides nitrogenous source; Repone K is for composite fertilizer provides the potassium source; Ammonium chloride is for composite fertilizer provides nitrogenous source; Monoammonium phosphate is for composite fertilizer provides phosphorus source and nitrogenous source.
The present invention has realized the suitability for industrialized production of humic acid urea; Form stable radical through the ion exchange reaction of humic acids carboxyl and the generation of urea carboxamido-group, the chemisorption that hydrogen bond association forms; The decomposition of urea is slowed down, improved the utilization ratio of urea efficiency and nitrogen.The present invention can slow down the release rate of nitrogen element in the compound manure, greatly improves farm crop to nutrient absorbing, eliminates common composite fertilizer in the waste of plant growth quick-acting in early stage too much, the drawback that the later stage is under-supply.Through the field experiment checking, significant urea synergism and effect of increasing production are arranged.
The present invention has less investment, technology is simple, and running cost is hanged down the advantage with good fertilizer efficiency.
