Description
Technical field
The present invention relates to compound fertilizer, be specifically related to molybdenum modification biological charcoal fertilizer and preparation method thereof.
Background technology
Whether cereal crops still in the field of planting of industrial crops, the means of fertilising are just used to carry for a long time
High crop yield and quality.From the earliest use farm organic fertilizer to using inorganic fertilizer, then to using composite organic-inorganic fertilizer.Execute
Cereal crops or yield of commercial crops and quality are all had a great impact by fertile kind, dose and proportioning etc..Traditional fertilizer
Although especially composite organic-inorganic fertilizer serves good effect in terms of improving crop yield.But, traditional fertilizer is deposited
Unreasonable at composition and nutrient formula, it is little to recover soil fertility, improve Soil structure, the most also can have side effects,
Cause soil compaction etc..
Compound fertilizer refers to the chemical fertilizer containing two or more nutrient, and it is high, secondary that compound fertilizer has nutrient content
The advantages such as composition is few and physical behavior is good, for balance fertilizing, improve utilization rate of fertilizer, promote that the stable high yield of crop has ten
Divide important effect.
Charcoal be bio-organic materials (biomass) in anoxia or anoxybiotic environment, after high temperature pyrolysis generate consolidates
State product.Can not only be used for the high-quality energy, soil conditioner, it is possible to seal as reducing agent, fertilizer slow release carrier and carbon dioxide
Deposit agent etc., be widely used to carbon fixation and emission reduction, water source purifying, heavy metal adsorption and soil improvement etc., can be to a certain extent
The hot issue that the whole world such as climate change, environmental pollution and soil function degeneration is deeply concerned provides solution.It is at hypoxia ring
Under border, by Pintsch process, timber, grass, corn stalk or other Wastes of Crops carbonization are formed.Though charcoal can as fertilizer,
But its microcellular structure is less, specific surface area is relatively low, and the nutrient retained includes that trace element is less, general when therefore using
Need to add other fertilizer.
Molybdenum is one of required micronutrient element of plant.Molybdenum is the component of azotase and nitrate reductase, lacks molybdenum
The synthesis of nodule nitrogen fixation and protein can be affected.Molybdenum can also promote crop to the absorption of phosphorus and Phos to the conversion of organophosphor.
Molybdenum vitamin C and the generation of carbohydrate, operate and convert in all play an important role.
Summary of the invention
It is an object of the invention to provide molybdenum modification biological charcoal fertilizer and preparation method thereof.
The technical scheme realizing the object of the invention is:
A kind of molybdenum modification biological charcoal is fertile, is made up of the raw material of following weight parts:

Wherein, described agriculture and forestry by-product is corn straw, wheat stalk, rice straw, cotton stalk, corn cob, Semen Gossypii
In shell, rice husk, Pericarppium arachidis hypogaeae, bean shell, shell, bagasse, peel, cull fruit, the residual branch of trees, wood flour one or more
Mixture, water content control is at 8-12%.
Described human and animal excreta is that the human and animal excreta chosen is dried or dried, and is ground into powder, and mixing forms, water content control
System is at 18-20%.
Described additive is ammonium molybdate and sodium molybdate example in mass ratio is that 1:2 mixes.
Described activator is molybdenum trioxide.
The preparation method that above-mentioned molybdenum modification biological charcoal is fertile, comprises the steps:
(1) agriculture and forestry by-product is dried, is ground into powder, standby；
(2) human and animal excreta is put in above-mentioned biomass material, stir, obtain mixture 1；
(3) additive prepared and activator are added in the above-mentioned biomass material mixture 1 with human and animal excreta, stir
Mix uniformly, it is thus achieved that mixture 2；
(4) mixture 2 after step (3) processes being put into pyrogen feed bin, in storehouse, filling rate is more than 80%, by material
Storehouse is heated to 160-190 DEG C, and is incubated 45-55 minute, utilizes the steam produced fully to be discharged by residual air in storehouse；
(5) will be in the mixture after step (4) processes send into cracking apparatus, intensification 260-300 DEG C, keep this temperature
15-18 minute, then in 3-5 minute, it is warming up to 470-500 DEG C, and keeps this temperature 3-4h, then chilling in 3-5 minute
To 180-200 DEG C, keep this temperature 40-50 minute, make material be sufficiently complete natural cooling after carbonization, obtain described molybdenum modified
Charcoal fertilizer.
Advantages of the present invention is: the charcoal of the present invention has bigger specific surface area, and the organic matter that improve soil contains
Amount；Use human and animal excreta and agriculture and forestry by-product as primary raw material, relatively make, merely with agriculture and forestry by-product, the charcoal that raw material obtains
Fertile containing more rich nitrogen, phosphorus, potassium and trace element.As low cost non-chemically fertilizer, product of the present invention can be organic agriculture
Industry, green agriculture provide the guarantee in yield, and preparation method is simple, controlled, easily implement, and are effectively processing human and animal excreta and life
While material, than traditional biological charcoal fertilizer, there is higher absorption property and higher fertilizer efficiency, can replace within the specific limits
Chemical fertilizer application, has the prospect of industrialization promotion, and significantly economic benefit, environmental benefit and social benefit.
