The method is mainly (mainly to comprise cell membrane and the arthropodan ectoskeleton of fungi with chitin kind biomass castoff, as: shell, the fungus sporophore residue etc. of crustacean shrimp, crab, insect) be raw material, under the condition of vacuum or anoxic, add thermal decomposition and obtain liquid heat hydrolysis products, then add public nuisance-free agricultural chemicals auxiliary agent to be prepared into public nuisance-free agricultural chemicals in pyrolysis liquid; After this public nuisance-free agricultural chemicals dilute with water, can use. Public nuisance-free agricultural chemicals prepared by the method not only has antibacterial wide spectrum, eco-friendly characteristic, and there is 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.
Description
Technical field:
The invention belongs to public nuisance-free agricultural chemicals technical field.
Background technology:
Living beings refer in organic matter except fossil fuel, all renewable materials that derive from plant, animal and microorganism.Chitin is extensively present in the cell membrane of insects, aquatic crustacean shell and Mycophyta, algae, on earth, and firstMore than a year biosynthesis amount for shell element reaches 10,000,000,000 t, be that a kind of reserves are only second to the extremely abundant renewable of stringOrganic resource. Along with the day by day exhaustion of fossil resource, the recycling of reproducible living beings is subject to people's generally passNote. Utilizing pyrolytic technique can be three kinds of products by biomass conversion: liquid (pyrolysis liquid), solid (charcoal) is gentleBody (pyrolysis gas). The research of utilization of cellulose series biomass thermal decomposition product is more, as: pyrolysis gas can be used as combustionGas, pyrolysis liquid can do liquid fuel after modification, and solid biologic carbon has the similar characteristic of active carbon, also has wide answeringBy prospect; For another example: a kind of preparation 1 from pyrolysis oil (being pyrolysis liquid) is disclosed in Chinese patent (ZL00107956.5),The method of 6-dehydration-β-D-glucopyranose; Zhang Suping etc. have summarized biomass pyrolysis liquid refinement treatment and have prepared fuelProgress (new forms of energy,, 22 volumes, 10 phases: 12-17 page in 2000). Pass through about chitin kind living beings at presentPyrolysis transforms the rarely seen report of document of recycling in addition.
Chitin (also claiming chitin, Chitin) is with β-Isosorbide-5-Nitrae glycosidic bond shape by N-acetyl-2-amino-2-deoxy-D-GlucoseThe polysaccharide that formula is formed by connecting. Chitin being widely used in food, medical industry and environmental protection, as: for clarifying fruitJuice, as medical fibre and pharmaceutical carrier, as water body purification flocculant, etc. Correlative study, writes at Jiang Ting greatIn monograph (" chitin ", 2003, Chemical Industry Press), carry out detailed introduction. Although the exploitation value of pure chitinBe worth higher, but chitin kind living beings (as: shrimp and crab shells, fungus sporophore etc.) are except containing chitin (chitin)Outer also have a large amount of other compositions (as protein, calcareous etc.), and purification process is more loaded down with trivial details, after purifying abundant residues thing afterContinuous difficult treatment, easily causes environmental pollution. Chitin kind living beings are transformed in gained pyrolysis liquid and are contained in a large number and contain by pyrolysisThe little molecular organic compound of nitrogen, these micromolecular compounds are obvious to the growth inhibition effect of phytopathogen, and to plantingThing growth has facilitation, therefore, is expected to the public nuisance-free agricultural chemicals for the preparation of controlling plant diseases, and Promoting plant growthConditioning agent. On the other hand, these micromolecular compounds are easily degraded by microorganisms at occurring in nature, for agricultural production notEasily residual, environmental friendliness; Correlative study has no report.
Summary of the invention:
The object of this invention is to provide a kind of novel non-pollution agricultural chemicals of preparing taking chitin kind living beings as primary raw material, and carryFor the preparation method of this novel non-pollution agricultural chemicals that has controlling plant diseases and Promoting plant growth concurrently. The method main featureBe: with chitin kind biomass castoff (mainly comprise cell membrane and the arthropodan ectoskeleton of fungi, as moving in: crustThe shell of thing shrimp, crab, insect, fungus sporophore residue, mold fermentation residue etc.) be raw material, at the bar of vacuum or anoxicUnder part, add thermal decomposition and obtain pyrolysis liquid, then add public nuisance-free agricultural chemicals auxiliary agent to be prepared into public nuisance-free agricultural chemicals in pyrolysis liquid; ThisAfter public nuisance-free agricultural chemicals dilute with water, can use. Public nuisance-free agricultural chemicals prepared by the method not only has antibacterial wide spectrum, environmental friendlinessCharacteristic, and there is the effect of Promoting plant growth; Preparation method not only technique is simple, low production cost, Er QieweiThe utilization of chitin kind abandoned biomass provides a new way.
Preparation process and the using method of novel non-pollution agricultural chemicals of the present invention are as follows:
1. chitin kind living beings are quantitatively put into vacuum pyrolysis reactor, vacuumize, and are heated to 220 DEG C-600 DEG C and carry out heatSeparate, 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 condenser collector, most of product is condensed into liquid, obtains pyrolysis liquid.
2. in above-mentioned pyrolysis liquid, add 0-3.5 water doubly, mix, leave standstill 3-24 hour, filter, remove filter residue,The nuisanceless surfactant for agricultural chemicals (as: tween series) that adds 0.5-15% in filtrate, obtains novel nothingPublic hazards agricultural chemicals.
3., when the novel non-pollution agricultural chemicals that the 2nd step obtains uses, using water as diluent, diluted 50 to 5000 times.Solution spray after dilution is processed crops or other plant, or is stained with root for seed dressing, while 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 to facilitation.
Detailed description of the invention:
The novel non-pollution pesticide control plant disease of being produced by technical solution of the present invention, and can promote to subtract the growth of plantThe use amount of few chemical fertilizer, reduces the use amount of high malicious chemical pesticide, thereby improves farm environment quality; And production cost is low,Effectively utilize discarded object, reduced pollutant emission. Detailed description of the invention is as follows:
Embodiment 1: chitin kind living beings (crab shell or shrimp shell) are prepared novel non-pollution agricultural chemicals
Take 2 kilograms of crab shells or shrimp shell, be broken into 3 centimetres of following fractionlets, put into 10 liters of vacuum pyrolysis reactors,Vacuumize, be heated to 400 DEG C 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 condenser collector, most of product is condensed into liquid,Obtain pyrolysis liquid.
To the water that adds 1 times in above-mentioned pyrolysis liquid, mix, leave standstill 12 hours, filter, remove filter residue, in filtrateAdd 5% Tween 80, obtain novel non-pollution agricultural chemicals.
Embodiment 2: chitin kind living beings (fungal cell wall) are prepared novel non-pollution agricultural chemicals
To extract mushroom residue after lentinan as raw material, take 2 kilograms, put into 10 liters of vacuum pyrolysis reactors,Vacuumize, be heated to 380 DEG C 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 condenser collector, most of product is condensed into liquid,Obtain pyrolysis liquid.
