Description

Multifunction mixed compound fertilizer

The invention belongs to a kind of fertilizer.

Common compound three element fertilizers based on bicarbonate of ammonia except fertilely, have outside the promoter action the growths of farm crop, can not possess multiple functions such as weeding, deinsectization, diseases prevention simultaneously.Therefore, use after this class fertilizer, also must carry out artificial or additive method weeding,, so, not only brought a lot of troubles, and increased labor force's spending, improved the production cost of farm crop to the user to farm crop or diseases prevention or deinsectization.Bicarbonate of ammonia has weakness such as volatile, fertilizer efficiency period is short in addition, therefore will be subjected to certain restriction to the use based on the compound ternary chemical fertilizer of carbon ammonium.So the peasant urgently wishes to have that function is many, fertilizer efficiency period is grown, the appearance of cheap and good-quality compound chemical fertilizer.

The objective of the invention is to shortcoming at above-mentioned composite fertilizer, what provide is a kind of based on bicarbonate of ammonia, add multiple major ingredient such as potash fertilizer, phosphate fertilizer, make the compound chemical fertilizer that possesses multiple functions such as fertile ground, diseases prevention, deinsectization, weeding are arranged simultaneously, and the production technique of this fertilizer.

The method that the present invention finishes is: main component is by bicarbonate of ammonia, potash fertilizer (KCl, K2SO4), phosphate fertilizer (calcium superphosphate, fused(calcium magnesium)phosphate), organic substance (brown coal)-humic acids, zinc sulfate, siccative (containing the required trace elements of various plants growth such as silicon, iron, calcium), borax, formaldehyde, remove herbal medicine (Nong Defeng: DP-1), internal-suction type deinsectization medicine compositions such as (pyrethrins).The content of each major ingredient is respectively: ammonium hydrogencarbonate is 40-65%, potash fertilizer is 8-20%, phosphate fertilizer is 10-20%, the siccative that includes various trace elements such as ferrosilicon calcium is 5-8%, and organic humic acid is 6-15%, and zinc sulfate is 0.3-0.5%, formaldehyde is 0.2-0.5%, borax is 0.2-0.5%, and weedicide is 0.2-0.8%, and deinsectization medicine is 0.5-5%.Production technique is that the siccative that will contain various trace elements such as silicon oxide, iron, calcium, zinc, manganese, boron earlier carries out heat drying, and broken fineness is about 200 orders, mixes with bicarbonate of ammonia.In the process that the powder for drying agent of this moment and bicarbonate of ammonia stir, constantly the free-water in the absorption bicarbonate of ammonia reaches the purpose of dry bicarbonate of ammonia, thus the decomposition rate of the bicarbonate of ammonia that slows down, reduce the volatilization of ammonia in the bicarbonate of ammonia, prolong the fertilizer efficiency period of bicarbonate of ammonia.Because the speed that how much will directly have influence on the bicarbonate of ammonia decomposition rate of the water content of bicarbonate of ammonia own.Then through with the siccative combination drying after bicarbonate of ammonia in, the adding granularity is about 40 orders, the brown coal of humic acids content 〉=40% fully mix.Since the humic acids in the brown coal can with free ammonia and the ammonia root generation chemical reaction in the bicarbonate of ammonia, generate stable organic substance ammonium humate, its decomposition rate be bicarbonate of ammonia decomposition rate 1/tens; Humic acids in the brown coal can form thin film on the surface of bicarbonate of ammonia in addition; protection bicarbonate of ammonia is not volatile; thereby reached the purpose that overcomes the volatile weakness of bicarbonate of ammonia, improved the stability of bicarbonate of ammonia, its fertilizer efficiency period is existing more than two times of bicarbonate of ammonia.When adding the humic acids brown coal; in bicarbonate of ammonia, add phosphate fertilizer, potash fertilizer, zinc sulfate, formaldehyde, borax, mix evenly; purify cooling; generate some salt of wormwood that can prolong the bicarbonate of ammonia fertilizer efficiency period, ammonium chloride etc. in the chemical reaction again; the ammoniacal liquor that adds concentration again and be 20-25% is moistening, send and squeezes out the particulate state that particle size diameter is the 4-8 millimeter in the Squeezinggranulator, adds the deinsectization medicine weedicide then in particle; after stirring, packing is finished product.

Advantage of the present invention is: one, the starting material source is wide, and technology is uncomplicated, and product cost is low; Two, humic acids can change Soil structure in the fertilizer, helps overcoming because of the life-time service chemical fertilizer, causes soil compaction, and the problem that fertility descends is improved soil function and crumb structure, and the fertility degree that improves soil is identical with the effect of the farm manure of using; Three, the zinc fertilizer in the fertilizer can be prevented and treated the seat root and stem of certain plants disease of paddy rice, formaldehyde can be prevented and treated the disease of farm crop such as rape, cotton, can also prevent and kill off weeds such as Herba Eleocharitis acicularis in the soil, nutgrass flatsedge, short arrowhead, Sheathed Monochoria, Herba Clinopodii Polycephali, barnyard grass grass, Herba Marsileae Quadrifoliae, and various insects, this fertilizer with multiple functions such as fertile ground, weeding, diseases prevention, deinsectizations, its release action is slow, and fertilizer efficiency period is long, drug effect power is big, is that existing ternary compound chemical fertilizer is incomparable; Four, make siccative with the slag of fluidizing furnace, turn waste into wealth, cost is low, and is simple for production, and operational safety is reliable, and the slag for the fertilizer plant that produces bicarbonate of ammonia provides a good outlet again; Five, be applicable to that cash crop such as food crop, nonirrigated farmland rape, cotton such as paddy rice use, widely applicable, can produce good economic benefits and social benefit.

Most preferred embodiment of the present invention one: one, get the raw materials ready.Prepare required bicarbonate of ammonia and various starting material, the siccative that contains various trace elements such as silicon, iron, the calcium dehumidifying of heating, below grinding particle size to 200 order.Two, premix.Get bicarbonate of ammonia 45%, put into the spice bucket, add siccative 7.5% simultaneously, stir, siccative absorbs the free-water in the bicarbonate of ammonia, makes the water content of bicarbonate of ammonia be lower than 0.5%; Three, batching.In the raw material of premix, adding treated granularity is about 40 orders, contains the humic acids amount greater than 40% organism humic acids brown coal 7%, Repone K 18%, calcium superphosphate 11%, zinc sulfate 0.5%, borax 0.3%, formaldehyde 0.2%; Four, batch mixing, reaction.Fully spice is even, and in mixing process, organism absorbs free ammonia and ammonium root, the ammonium humate of generation, and salt of wormwood, ammonia chloride etc., thus can play the effect that bicarbonate of ammonia prolongs fertilizer efficiency period; Five, purification, moistening.Mix and mix uniform powdery fertilizer after fully reacting, adding concentration is that the ammoniacal liquor of 20-25% is an amount of, makes it moistening, utilizes into bulk; Six, extruder grain.Moistening batch mixing is sent into granulation in the extruding granulator, and particle diameter is the 4-8 millimeter; Seven, dosing is handled.In the fertiliser granulates of moulding, it is richly 0.7% agricultural to add weedicide, and deinsectization medicine adds pyrethrin pesticide 2%, mixes, and each particle surface is stained with medicine; Eight, weighed, bag distribution packaging, get product.
