Description
Technical field
The present invention relates to a kind of method of comprehensive utilization of agricultural wastes, relates more particularly to a kind of HTHP and prepares fertilizer
The method of material, belong to agricultural wastes recycling reutilization technology field.
Background technology
At present, problems be present in the vast rural area in China, the agricultural wastes utilization of resources, such as：Lack corresponding
Technology and equipment；It is simple, backward in technique to the handling process of agricultural wastes；Disposal ability and utilization scale are very limited etc.
Deng.Wherein, the problem of most primary is exactly that existing agricultural waste utilization mode can cause environmental pollution.Most of resource can only
Discarded or burn, utilization rate is very low, for example, agricultural crop straw more as fuel burnt as disposable Land use systems, no
Only capacity usage ratio only has 10%, and caused a large amount of nitrogen oxides, sulfur dioxide, hydrocarbon and cigarettes in combustion process
Dirt can directly pollute air.And for example, much all unprocessed direct returning to farmland, such Land use systems not only make feces of livestock and poultry
The nutriments such as the calcium that wherein contains, phosphorus are not used, and seriously pollute the environment such as waters, the soil on periphery, influence people
Body health.
Many studies have shown that, agricultural wastes, which are used as fertilizer, can both solve the problem of outlet of discarded object both at home and abroad, while again
It can improve and fertilizing soil.It is mostly that agricultural wastes are direct but prior art processing agricultural wastes method is more single
Fermented, manufactured solid organic fertilizer is often because nutrition content is low, production technology is simple, dog-eat-dog of the same trade etc.
Reason, economic benefit are very limited.
In addition, this fermentation process can only handle a kind of or a few discarded object more, and there is pollutant in processing procedure
The problem of secondary emission.In addition, with the technologies such as the development of agriculture cultivation technology, drip irrigation and spray irrigation application also increasingly
Extensively, and solid organic fertilizer be difficult adapt to as fertilization mode.
For long processing period, the crop material that value is low, string matter content is more, shell, mushroom slag, drink
The agricultural wastes such as factory waste residue are expected because the macromolecular hard-degraded substance such as its lignin, cellulose, pectin content is high, traditional hair
Fermenting process depends merely on the effect of microorganism to degrade, and it is big that fermenting speed is slow, nutrient scatters and disappears, and composting cycle is long and obtained fertilizer nutrient
Content is low.
Further, traditional fermentation process can not be directed to different discarded objects to the product of gained without selectivity
Composition and feature are utilized to greatest extent, are recycled ineffective.
Therefore, for current technology present situation, need the technology with preferable conformability and promotional value badly, break through current
A kind of mode can only utilize a kind of or a few discarded object obstacle, and improvement agricultural waste utilization is backward in technique, utilization rate
Low present situation, this not only has good realistic meaning and the value of environmental protection, is study hotspot and emphasis class in the art
Topic, is even more where the power that the present invention is accomplished and basis is leaned on.
The content of the invention
In order to solve above-mentioned problems of the prior art, more in order to provide brand-new agricultural wastes comprehensive utilization side
The preparation method of method and fertilizer, it is an object of the invention to provide the novel method that a kind of HTHP prepares fertilizer, this method
Available for all types of agricultural wastes are handled, the long processing period that is particularly suitable for use in, value are low, string matter content
The utilization of the agricultural wastes such as more crop material, shell, mushroom slag, beverage factory waste residue, methods described can destroy cell
Wall and cellulose, the crystal structure of lignin, cellulose percent hydrolysis and lignin removing rate are high, and obtained concentrated liquid fertilizer can
To adapt to dropper, spray, the fertilization mode such as spray, using simple, quick；Organic fertilizer is decomposed completely, and nutrient content is high, applies
With safe and effective.
