The inventor carries out the animal bone anaerobic first and fires and must deceive bone black.Analyze after tested, its active substance is a benchmark with black bone black weight, contains P
2O
535~40%, CaO 35~40%, and C 7~10%, and containing the MgO representative value is 0.31%, and containing the N representative value is 0.81%.
The objective of the invention is to improve the effect of known composite fertilizer, the composite fertilizer that contains black bone black is provided, this composite fertilizer is to improving the soil, and increasing crop yield has beyond thought before this superior effect with the raising crop quality.
The special character that the present invention contains its technical solution of composite fertilizer of black bone black is to contain black bone black, fertilizer and inorganic fertilizer.
Described fertilizer is the oil cake that is rich in organic and nitrogen element, and inorganic fertilizer is urea and monoammonium phosphate.
Composite fertilizer of the present invention can be combined by black bone black, fertilizer, inorganic fertilizer, zeolite powder and binding agent.
Described fertilizer is combined by oil cake and brid guano, inorganic fertilizer is combined by urea, monoammonium phosphate, Repone K, ammonium sulfate and calcium superphosphate, with the fertile gross weight of compound is benchmark, and described these components are respectively: black bone black 8~15%, urea 20~25%, monoammonium phosphate 4~12%, Repone K 0~14%, vitriolate of tartar 0~30%, oil cake 20~36%, brid guano 0~15%, calcium superphosphate 0~12%, zeolite powder 0% or 8%, binding agent 4%.
Composite fertilizer of the present invention can be the composite fertilizer by described component mixing, granulation gained; Described binding agent can be a cement.
The black bone black that the present invention is used is fired under the anaerobic situation with animal bone and to be formed.This is with animal bone, handle the back bone that stays as animal slaughterings such as ox, pig, sheep, fill in capping and have in the maturing vessel of production well, fired 2~3 hours in 1000~1500 ℃, obtain black bone black piece, again this black bone black piece is pulverized, is sieved black bone black powder.Black bone black of the present invention is meant this black bone black powder.Maturing vessel, ready-made can use irony oil tube.Iron oil tube removes lid, fills described bone, adds a cover and seals with yellow mud etc., cover and leave production well, ℃ (T is a firing temperature) fired 2~3 hours in 1000 ℃≤T<1500, burnt and finished, it is fast that black bone black is taken out in opening after water-cooled, pulverize again, sieve black bone black powder.Fill animal bone in the maturing vessel, most air in the tube can be supplanted.Fire and produce water vapor early stage, discharge, meanwhile the part air is squeezed away in the lump, make bone carbonization under the anaerobic situation from the container production well.Need cooling could take out bone black after firing, otherwise the bone black ingress of air of the condition of high temperature will combustion oxidation.
Granulation of the present invention is that described black bone black, fertilizer and inorganic fertilizer are mixed, and adding water is 3% of compound gross weight, granulation, and drying is made product then.Its technical process is: black bone black, fertilizer and inorganic fertilizer metering → belt conveying → mixing → belt conveying → middle hopper → stepless change charging machine → pair roller type granulation → belt conveying → product sieve → product drying → finished product packing → check warehouse-in.
Composite fertilizer of the present invention, since be with nutrient quick-acting inorganic fertilizer, be rich in the long-lasting fertilizer of element such as organic matter and nitrogen, phosphorus, potassium and tool and be rich in phosphorus, calcium, carbon and the black bone black of element such as nitrogenous, magnesium, mix, so have significant excellent results improving the soil, improve crop yield and quality.Because black helps heat absorption and insulation, so be added with this compound fertilizer of black bone black, applies the soil, winter, ground temperature can rise 1~5 ℃, can prevent effectively that the winter crops freeze injury from taking place.Test shows that the adding of black bone black can effectively prevent the generation of crop root disease and pest.Black bone black has stronger adsorption, and it adds, and also can prevent the loss of fertilizer nutrient, improves fertilizer utilization ratio, reduces the fertilising cost.The farmingization experimental test shows, is added with this composite fertilizer of black bone black, can impel the crops seedling stage growth, increases the fruit sugariness, increases output, impels the crop precocity, and can increase ground temperature winter, prevents that the crop frozen injury phenomenon from taking place.Research and experiment shows that composite fertilizer of the present invention has characteristic:
(1) good this composite fertilizer of fertilizer efficiency has the performance and the fertilizer efficiency of organic fertilizer, chemical fertilizer, little fertilizer concurrently, imposes on cash crop and compares with common multiple fertilizer, and volume increase about 15~30% imposes on food crop and can improve output about 10~20%;
(2) organic content Gao Benfei is rich in organic matter, it is used and can improve soil with organic matter content, and can make full use of soil potential fertility, this reduces and pollutes reducing applying quantity of chemical fertilizer, improves chemical fertilizer utilization ratio, preserve the ecological environment, improve soil physical and chemical property, increasing soil fertility has all had guarantee, meets the requirement of green food with fertilizer;
(3) nutrient element complete edition fertilizer contains the nitrogen that has immediate effect, phosphorus, potassium, moderate-element sulphur, calcium, magnesium and various trace elements and 25% above organic matter etc.;
(4) instant effect is because the combining of organic nutrient and inorganic nutrients, and makes base manure and topdresses, and can not burn seedling early stage, and the later stage can not taken off power, fertile very fast and steady length;
(5) applicable surface Guangzhou Honda fertilizer is applicable to various cash crop such as grape, strawberry, citrus, sugarcane, watermelon, shaddock, vegetables, cotton, tealeaves, tobacco leaf, flowers, corydalis tuber, mao bamboon, broad bean etc. recklessly, food crop such as paddy rice, barley and wheat, corn, jowar, soybean, rape and culture fishery.
Tabulate the assembly of the fertile embodiment of this compound below, wherein have: universal, red bayberry tailored version, bamboo shoots tailored version, tea tree tailored version, corydalis tuber (Chinese medicinal materials) tailored version, paddy rice tailored version, universal and flowers tailored version.Numeral is the kilogram number in the table, and the fertile total amount of all types of compounds is 1000 kilograms.
