Abstract
The present invention is aimed at providing a method for preparing pesticide capable of preventing and curing plant disease by using biomass pyrolysis liquor as main raw material. Said biomass pyrolysis liquor is obtained by using biomass (mainly including various agricultural wastes) through a certain pyrolysis process. Said biomass pyrolysis liquor can be directly diluted by using water and can be used for preparing pesticide for controlling plant diseases. Besides, the pH value of the biomass pyrolysis liquor can be regulated to neutrality by adding ammonia water or adding surfactant, after having been diluted said biomass pyrolysis liquor can be used for spraying plants or treating sees for preventing and curing plant diseases.
Description
Technical field
The invention belongs to biological pesticide technical field.
Technical background
Living beings are meant that in organic matter except that fossil fuel, all derive from the renewable material of plant, animal and microorganism.It mainly comprises crops, agricultural or agro-product processing discarded object (stalk, sugar beet pulp, bagasse etc.), trade waste (discarded object after the plant fermentation, paper pulp and paper trade waste), forestry waste and animal waste (animal wastes) etc.Along with the exhaustion day by day of fossil resource, reproducible living beings utilization is subjected to people's common concern.Utilize pyrolytic technique living beings can be converted into three kinds of products: liquid (pyrolysis liquid), solid (coke) and gas (pyrolysis gas).Wherein, mainly contain hundreds of kind organic compounds such as phenols, alcohols, organic acid, aldehydes, carbohydrate, aromatics in the pyrolysis liquid.At present, the utilization of pyrolysis liquid is mainly used in the chemicals that extracts high added value, or is used as fuel through modification with after handling.As: a kind of preparation 1 from pyrolysis oil (being pyrolysis liquid) is disclosed in the Chinese patent (ZL00107956.5), the method for 6-dehydration-β-D-glucopyranose; Zhang Suping etc. have summarized progress (new forms of energy,, 22 volumes, 10 phases: the 12-17 page or leaf) in 2000 that the biomass pyrolysis liquid refinement treatment prepares fuel.Yet there are no the report that biomass pyrolysis liquid is used for controlling plant diseases.
Summary of the invention
The purpose of this invention is to provide a kind of is primary raw material with the biomass pyrolysis liquid, prepares the method for controlling plant diseases agricultural chemicals.This method main feature is: (1) with living beings (mainly comprising agricultural, farming industry, forestry and animal the like waste) pyrolysis liquid or the residue pyrolysis liquid after extracting the high added value chemicals directly or after simple process, be used for agricultural chemicals; (2) with water as thinner, the dilution ratio of pyrolysis liquid is 0.02%-2%.The agricultural chemicals of this method preparation has antibiotic wide spectrum, and raw material is inexpensive, eco-friendly characteristic, and the technology of method own is simple, and provides a new way for the utilization of abandoned biomass.
Biomass pyrolysis liquid of the present invention is used for theing contents are as follows of controlling plant diseases agricultural chemicals:
1. the used biomass pyrolysis liquid of the present invention is to obtain through pyrolysis with living beings (mainly comprising agricultural, farming industry, forestry and animal the like waste), comprises the residue pyrolysis liquid that has extracted behind the high added value chemicals.
2. above-mentioned pyrolysis liquid can be directly used in the agricultural chemicals of controlling plant diseases, perhaps regulates pH to neutral with ammoniacal liquor, perhaps adds the surfactant of 0.1%-10%.
With water as thinner, with pyrolysis liquid, add 50 to 5000 times of the pyrolysis liquid dilutions of ammoniacal liquor and/or surfactant.
4. the solution spray after the dilution is handled crops or other plant, can effectively prevent and treat the generation and the development of plurality of plant diseases.
Embodiment 1: maize straw pyrolysis liquid is to the inhibitory action of different fungi microbes
Get 3 milliliters of maize straw pyrolysis liquid, add 1 liter of PDA medium, behind the mixing, fall dull and stereotyped.Inoculate different fungi microbes, as: aspergillus niger (Aspergillus niger), wood mould (Trichoderma sp.), scab of cucumber pathogen (Cladosporiumcucumerinum) etc. compare with the PDA culture medium flat plate that does not add pyrolysis liquid.Cultivate under suitable temperature, various microorganisms are well-grown on the control medium flat board, and aspergillus niger and the faint growth of wooden mould energy on the medium that adds pyrolysis liquid, pathogen then can not grow fully.
Embodiment 2: maize straw pyrolysis liquid control cucumber downy mildew
Cucumber plant is handled in the pyrolysis liquid aqueous solution (containing low quantity of surfactant) spraying with 0.2%, handles comparing with clear water.Inoculation cucumber downy mildew pathogen (Pseudoperonospora cubensis) spore.After treating that adjoining tree obviously falls ill, the disease index of investigating respectively and contrasting calculates control efficiency.The result shows, the plant of handling with pyrolysis liquid to the control efficiency of jaundice downy mildew between 37%-85%.
Embodiment 3: sawdust pyrolysis liquid is prevented and treated cladosporium leaf and fruit mould of tomato
Sawdust pyrolysis liquid is adjusted to neutrality with ammoniacal liquor, handles tomato plant, handle comparing with clear water with 0.2% the pyrolysis liquid aqueous solution (containing low quantity of surfactant) spraying.Inoculating tomato leaf mold pathogen (Fulvia fulva).After treating that adjoining tree obviously falls ill, the disease index of investigating respectively and contrasting calculates control efficiency.The result shows, the plant that pyrolysis liquid is handled to the control efficiency of graw mold of tomato between 39%-76%.And this pyrolysis liquid has the effect that promotes plant strain growth.
Claims (3)
1. one kind is primary raw material with the biomass pyrolysis liquid, method as the controlling plant diseases agricultural chemicals, it is characterized in that, plant or the seed dressing of plant handled in spraying behind the direct dilute with water of pyrolysis liquid, or plant or the seed dressing of plant are handled in spraying after regulating pH with ammoniacal liquor, or plant or the seed dressing of adding low quantity of surfactant spraying processing plant, with controlling plant diseases.
2. in 1 described method of claim the, pyrolysis liquid is that living beings prepare through pyrolytic technique, comprises the residue pyrolysis liquid that has extracted behind the high added value chemicals.
3. in 1 described method of claim the, can be according to instructions for use, pyrolysis liquid or pyrolysis liquid water or add 50 times to the 5000 times uses of water dilution that show activating agent through overregulating.
