Abstract
The invention relates to a method for preparing a novel non-polluted pesticide through chitin biomass pyrolysis and belongs to the technical fields of non-polluted pesticides and biomass recycling. The method mainly comprises the following steps of: with chitin biomass wastes (mainly comprising cell walls of fungi and exoskeletons of arthropods, such as shelled animals including shrimps and crabs, insect shells, fungus fruiting body residues and the like) as raw materials, carrying out the pyrolysis on the raw materials under the condition of vacuum or oxygen deficiency to obtain a liquid pyrolysis product, and then, adding a non-polluted pesticide adjuvant into pyrolysis liquid to prepare the non-polluted pesticide, wherein the non-polluted pesticide can be used after being diluted by using water. The non-polluted pesticide prepared by using the method not only has the characteristics of broad antibacterial spectrum and environment friendliness, but also has an effect on promoting the growth of plants; and the method is not only simple in process and low in production cost, but also provides a new approach for the utilization of waste chitin biomasses.
Description
Technical field:
The invention belongs to the public nuisance-free agricultural chemicals technical field.
Background technology:
Living beings refer to that in organic matter except fossil fuel, all derive from the renewable material of plant, animal and microorganism.Chitin extensively is present in the cell wall of insects, aquatic crustacean shell and Mycophyta, algae, on earth, more than the year biosynthesis amount of chitin reaches 10,000,000,000 t, it is the extremely abundant renewable organic resource that a kind of reserves are only second to vegetable fiber.Along with the day by day exhaustion of fossil resource, the recycling of reproducible living beings is subject to people's common concern.Utilizing pyrolytic technique can be three kinds of products with biomass conversion: liquid (pyrolysis liquid), solid (charcoal) and gas (pyrolysis gas).The research of utilization of cellulose series biomass thermal decomposition product is more, as: pyrolysis gas can be used as combustion gas, and pyrolysis liquid can be done liquid fuel after modification, and solid biologic carbon has the similar characteristic of active carbon, also has broad application prospects; For another example: disclose a kind of method for preparing 1,6-dehydration-β-D-glucopyranose from pyrolysis oil (being pyrolysis liquid) in Chinese patent (ZL00107956.5); Zhang Suping etc. have summarized progress (new forms of energy,, 22 volumes, 10 phases: the 12-17 page) in 2000 that the biomass pyrolysis liquid refinement treatment prepares fuel.At present transform the in addition rarely seen report of document of recycling about the chitin kind living beings by pyrolysis.
(also claim chitin, be Chitin) with polysaccharide that β-Isosorbide-5-Nitrae glycosidic bond form is formed by connecting by N-acetyl-2-amino-2-deoxy-D-Glucose to chitin.Chitin being widely used in food, medical industry and environmental protection, as: be used for clear juice, as medical fibre and pharmaceutical carrier, as the water body purification flocculant, etc.Correlative study has been carried out detailed introduction in the monograph (" chitin ", 2003, Chemical Industry Press) that Jiang Tingda writes.Although the value of pure chitin is higher, but chitin kind living beings (as: shrimp and crab shells, fungus sporophore etc.) also have a large amount of other compositions (as protein, calcareous etc.) except containing chitin (chitin), purification process is more loaded down with trivial details, after purifying, the subsequent treatment of abundant residues thing difficulty, easily cause environmental pollution.The chitin kind living beings transform by pyrolysis and contain a large amount of nitrogenous little molecular organic compounds in gained pyrolysis liquid, these micromolecular compounds are obvious to the growth inhibition effect of phytopathogen, and plant growth there is facilitation, therefore, be expected to the public nuisance-free agricultural chemicals for the preparation of controlling plant diseases, and the conditioning agent of Promoting plant growth.On the other hand, these micromolecular compounds easily are degraded by microorganisms at occurring in nature, be used for agricultural production be difficult for residual, environmental friendliness; Correlative study has no report.
Summary of the invention:
The purpose of this invention is to provide a kind of novel non-pollution agricultural chemicals of the preparation take the chitin kind living beings as primary raw material, and this preparation method who has the novel non-pollution agricultural chemicals of controlling plant diseases and Promoting plant growth concurrently is provided.The method main feature is: with chitin kind biomass castoff (cell wall and the arthropodan ectoskeleton that mainly comprise fungi, as: the shell of crustacean shrimp, crab, insect, fungus sporophore residue, mold fermentation residue etc.) be raw material, under the condition of vacuum or anoxic, add thermolysis and obtain pyrolysis liquid, then add the public nuisance-free agricultural chemicals auxiliary agent to be prepared into public nuisance-free agricultural chemicals in pyrolysis liquid; Can use after this public nuisance-free agricultural chemicals dilute with water.The public nuisance-free agricultural chemicals of the method preparation not only has antibiotic wide spectrum, eco-friendly characteristic, and have the effect of Promoting plant growth; Preparation method not only technique is simple, low production cost, and provide a new way for the utilization of chitin kind abandoned biomass.
Preparation process and the using method of novel non-pollution agricultural chemicals of the present invention are as follows:
1. the chitin kind living beings are quantitatively put into vacuum pyrolysis reactor, vacuumize, be heated to 220 ℃-600 ℃ and carry out pyrolysis, and vacuumize continuously, the thermal decomposition product of chitin is at high temperature gaseous state, under the continuous sucking of vavuum pump, leave reactor, enter in the condenser collector, most of product is condensed into liquid, namely obtains pyrolysis liquid.
2. add 0-3.5 water doubly in above-mentioned pyrolysis liquid, mix, standing 3-24 hour, filter, remove filter residue, add the agricultural chemicals of 0.5-15% with nuisanceless surfactant (as: tween series) in filtrate, namely obtain the novel non-pollution agricultural chemicals.
3. when the novel non-pollution agricultural chemicals of the 2nd step acquisition uses, as thinner, it is diluted 50 to 5000 times with water.Solution spray after dilution is processed crops or other plant, or is used for dressing seed, being stained with root when filling with root, seedling replanting, can effectively prevent and treat generation and the development of plurality of plant diseases, and the growth of plant is had facilitation.
Embodiment:
The novel non-pollution pesticide control plant disease of being produced by technical solution of the present invention, and can promote the growth of plant, reduce the usage amount of chemical fertilizer, reduce the usage amount of high malicious chemical pesticide, thereby improve the farm environment quality; And production cost is low, has effectively utilized discarded object, reduces pollutant emission.Embodiment is as follows:
