Abstract
The invention discloses a biological carbon fertilizer capable of promoting fertilizer efficiency. The biological carbon fertilizer is characterized by being prepared from the following raw materials in parts by weight: 60 to 80kg of biological carbon, 10 to 12kg of urea, 10 to 12kg of diammonium phosphate, 10 to 12kg of potassium sulphate and 6 to 10kg of additives. According to the invention, the biological carbon fertilizer takes crop straw as raw material components, and the straws used as the raw materials are low in cost and readily available in sources, and crushed into biological carbon powder through dehydration and deoxygenation and a way of high-temperature carbonization, the carbonization effect is good, and the carbon content is more than 25%, so that the straw carbonization rate is effectively improved, the carbon fertilizer is high in yield, the application effect is good, and heavy metals in soil can be passivated to improve the activity of soil microorganisms. The biological carbon fertilizer has a larger specific surface area and improves the organic matter content in the soil; as the low-cost non-chemical fertilizer, the product of the invention can provide a guarantee on yields of organic agriculture and green agriculture, and is further simple in preparation method, controllable and easy in implementation.
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 energy
Enough improve the charcoal fertilizer of fertilizer efficiency.
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 that can improve fertilizer efficiency.
The technical scheme realizing the object of the invention is:
A kind of charcoal fertilizer that can improve fertilizer efficiency, is made up of the raw material of following weight parts:

Described charcoal, is protected at nitrogen by one or more materials in cotton stalk, corn straw and wheat stalk
Protect lower oxygen barrier be pyrolyzed and pass through grinding and sieve and prepare.
The temperature of described oxygen barrier pyrolysis is 400-500 DEG C, and the time is 3-6h.
Described charcoal, particle diameter is 0.8-1.2mm, and density is 0.8-1g/cm3, and maximum water absorption is 450g/Kg.
Described auxiliary agent, is fusing urea and water mixes according to the ratio that mass ratio is 1:2.
The preparation method of above-mentioned a kind of charcoal fertilizer that can improve fertilizer efficiency, comprises the steps:
(1) weigh raw material according to described ratio, and by described raw material mix homogeneously, obtain compound；
(2) described compound is sent in cracking apparatus, be warming up to 250-280 DEG C, keep this temperature 10-12min, then exist
It is warming up to 450-470 DEG C in 6min, and keeps this temperature 3-4h, then in 4min, be chilled to 150-180 DEG C, keep this temperature
40-60min, natural cooling, obtain product.
Advantages of the present invention is: charcoal fertilizer of the present invention, is with agricultural crop straw as raw material components, its raw material used
Straw is with low cost, and source is easy to get, and is processed by dehydration deoxygenation and pulverizes the biological powdered carbon of formation, carbonization through high temperature carbonization mode
Effective, carbon content more than 25%, it is effectively increased the carbonization degree of straw, charcoal fertilizer yield rate is high, and application effect is good, and can be passivated
Heavy metal in soil, improves the vigor of soil microorganism；Meanwhile, fusing urea is used to serve as liquid phase as helping during preparation
Agent, can further improve the content of effective fertilizer composition, reduces the content of water so that utilization rate and the fertilizer quality of fertilizer more enter
One step is improved, and can reduce difficulty time prepared by product.And there is bigger specific surface area, improve the organic matter of soil
Content；As low cost non-chemically fertilizer, product of the present invention can be the guarantee in organic agriculture, green agriculture offer yield,
Preparation method is simple, controlled, easily implement, and while effectively having processed human and animal excreta and biomass, has than traditional biological charcoal fertilizer
There are higher absorption property and higher fertilizer efficiency, chemical fertilizer application can be replaced within the specific limits, before there is industrialization promotion
Scape, and significantly economic benefit, environmental benefit and social benefit.
