Description
Technical field
The present invention relates to the high-valued comprehensive utilization of biomass resource and field of environment pollution control, be specifically related to a kind of raw
Thing charcoal is fertile 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 compound organic and 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 compound organic and 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..
The survival and development of the mankind are all the time along with substantial amounts of people and the generation of animal residue, along with carrying of people's life
Height, human and animal excreta is the most serious to the pollution of environment.First, containing substantial amounts of organic matter and nitrogen, phosphorus, potassium etc. in human and animal excreta
Material, if directly discharging, can cause water pollution and eutrophication.Secondly, containing a large amount of pathogen in feces, easily cause big
Scale infectious disease popular.Again, fecal sewage produces toxic and harmful after organic decomposition of rotting, stench occurs.This
A little all severe contaminations the earth, water body, air and biome, and to health generation potential threat.Human and animal excreta simultaneously
Mostly have that moisture content is high, be difficult to store, the feature such as perishable of making moist, cause that cost of transportation is big, storage area big and is processed into
The problems such as this height.Therefore seek suitable human and animal excreta processing method and there is realistic meaning and Commercial Prospect.
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.
Summary of the invention
It is an object of the invention to provide a kind of charcoal fertilizer and preparation method thereof.
The technical scheme realizing the object of the invention is:
A kind of charcoal fertilizer, is made up of the raw material of following weight parts:
