Abstract
The invention discloses a preparation method of an ammonuim humate fertilizer, and the preparation method comprises the following steps: (1) preparing 80-120 parts by weight of peat with the moisture content of 30%-40% and 5-20 parts by weight of ammonium bicarbonate; and (2) evenly mixing the peat and the ammonium bicarbonate, stacking, and fermenting for 10-20 days. The ammonuim humate fertilizer uses the ammonium bicarbonate as an aminating agent for dry ammonification reaction of peat soil by adopting the characteristic that the ammonium bicarbonate is easy to absorb moisture to dissolve, water soluble humic acid content in the peat soil is increased, fulvic acid in water soluble humic acid is small in molecular weight, and high in active genes, can modify soil, improve the soil temperature, promote development of root system, and effectively adjust the soil pH, and has unique functions to solve soil compaction and the like. The ammonuim humate fertilizer is applied after mixing granulation, the crop yield is increased significantly, the fertilizer efficiency is long, and the fertilizer utilization rate is high. The preparation method of the ammonuim humate fertilizer is simple in production process, and reduces the cost of production.
Description
Technical field
The present invention relates to agriculture fertilizer field, relate in particular to a kind of preparation method of humic acidic ammonium fertilizer.
Background technology
Peat soil is the main raw material of fertilizer and organic-inorganic composite fertilizer.According to one's analysis, the organic content of peat soil is 40%-80%, and wherein humic acids content is 15%-40%, nitrogenous 1.0-2.5%, phosphorus 0.1-0.6%, and potassium 0.3-0.5%, is generally acid, and pH value is 5.6-6.4.Current most of manufacturer as raw material, only utilizes organic composition wherein to go to realize the technical indicator of organic commercial fertilizer and organic-inorganic composite fertilizer with peat soil, and humic acids composition in peat soil is not fully utilized.Humic acids in peat is divided into xanthohumic acid, ulmic acid, three components of Ulmic acids by the solvability in solvent.The part that is dissolved in acetone or alcohol is called ulmic acid, and the part that is insoluble to acetone or alcohol is called Ulmic acids, and part water-soluble or diluted acid is called xanthohumic acid (claiming again fulvic acid).What plant can absorb on agricultural is xanthohumic acid (claiming again fulvic acid) part.Xanthohumic acid is called fulvo acid composition in humic acid fertilizer analysis.Humic acids in peat soil is that free state humic acids and combined humic acids are water insoluble, the humate that unconverted is solubility, and plant is difficult to absorb.China Patent No. is to mention in ZL200710055809.4 humic acid in peat particle and preparation method thereof, humic acid in peat particle be by after humic acids spray peat, the organic granulated fertilizer that forms by granulation, wherein peat is that resolution is medium, ash oontent is at the meadow peat below 50%.Humate can be that humic acids content is at potassium humate, Sodium salts humic acids or the humic acid ammonia of more than 15% peat or brown coal or weathered coal.Yet the method need to first be prepared humate from peat, reproduces humic acids particle.Such production method has increased the energy consumption of production process, improves production cost and complex manufacturing technology.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of humic acidic ammonium fertilizer, and object is to utilize carbon ammonium to carry out ammonification to peat, makes the humic acids in peat be converted into fulvo acid soluble in water, is easy to be absorbed by plants.
For addressing the above problem, the invention provides following technical scheme:
A preparation method for humic acidic ammonium fertilizer, comprises the following steps:
(1) 80～120 parts, the peat that the water content of meter preparation is by weight 30%～40%, 5～20 parts of carbon ammoniums; Water content is the essential condition of ammonification, and water deficient ammonification is bad, xanthohumic acid low conversion rate, and excess moisture, easily causes pulverous peat soil, lumps again or form pasty state after ammonification.
(2) peat and carbon ammonium are mixed to rear accumulation, ferment 10～20 days.
Preferably, the preparation method of described humic acidic ammonium fertilizer, is characterized in that, further comprising the steps of: mix the mixture that obtains peat and carbon ammonium after fermentation (3) with other fertilizer, then granulation, pack.
Preferably, to comprise water content be 100 parts, 35% peat to meter by weight, 13 parts of carbon ammoniums.
Preferably, other described fertilizer comprise one or more the arbitrary combination in potash fertilizer, nitrogenous fertilizer, fused(calcium magnesium)phosphate, filter mud.
Preferably, the fineness of peat is 70～100 orders.
Beneficial effect of the present invention:
(1) utilize carbon ammonium to be easy to characteristic that the moisture absorption dissolves as transforming agent (being ammoniation agent), peat soil is carried out to dry method aminating reaction.Result is measured, and its fulvo acid content of peat soil rear mensuration soluble in water of processing without ammonification is only 0.26%, and after ammonification is processed, peat soil is measured its fulvo acid content after soluble in water and can be reached 10.5%～15.9%.And making method is easy, the production time is short, enhances productivity, and reduces production costs.
(2) to have molecular weight little for the xanthohumic acid in humic acids, and active gene is high, and improvement soil, improves ground temperature, impels well developed root system, effectively regulates soil acidity or alkalinity, solves the aspect unique effects such as soil compaction.With after mineral manure mixing granulation, use, crop yield obviously improves and fertilizer efficiency is long, utilization rate of fertilizer is high.Reason is that the base-exchange capacity of xanthohumic acid is high, to inorganic nutriment in a fertilizer volatile, easy loss, there is complexing to recommend ability with guarantee, can accelerate nitrogen enters and does in object, reducing phosphorus is fixed by the iron in soil, aluminium, improve the validity of phosphorus and trace element, plant absorbs soon, and chemical fertilizer utilization ratio raising reaches more than 80%.
Embodiment
