Abstract
The invention relates to a manufacturing method of herbicide of biogenic source, belonging to the technical field of preparation method of pesticide preparation, which is as follow: the biomass gasified liquid is added into a reaction kettle and the special addition agent is added in, the weight of which is 0.5 to 5 percent as heavy as the biomass gasified liquid, then the herbicide of biogenic source can be obtained after being stirred uniformly. The biomass gasified liquid is bamboo vinegar, pyroligneous or grass vinegar and the special addition agent is paraquat special addition agent SQ8208, HT201, EF8208 or EDW-518 or glyphosate special addition agent EF8108, EDW-596 or jixin-904. The herbicide of biogenic source made with the method belongs to steriland herbicide and has the advantages of good weed activity, good compatibility with the environment, good safety to the farm produce and people and low making cost. The herbicide of biogenic source can kill the weed in high concentration and boost the plant in low concentration, and also can improve the soil. The compound preparation made with complex compound of paraquat raw pesticide and glyphosate raw pesticide or preparation is better than the single paraquat raw pesticide or single glyphosate raw pesticide in weed result.
Description
Technical field
The invention belongs to pesticidal preparations preparation method technical field, be specially the production method of biological source herbicide.
Background technology
Gasifying biomass liquid is the aqueous material of brown that is condensed at normal temperatures by the gas that collection after vegetable material and the industrial wood waste pyrolysis thereof obtains, mainly contain Bamboo vinegar solution, pyroligneous liquor and careless vinegar liquid, Bamboo vinegar solution is the accessory substance that bamboo surplus material of processing obtains through high temperature pyrolysis, pyroligneous liquor is the accessory substance that wood machining residues and shell obtain through high temperature pyrolysis, and careless vinegar liquid is meant the accessory substance that herbaceous plant, crop stalk and crops husk obtain through high temperature pyrolysis.Be processed in the process of corresponding bamboo charcoal, charcoal and the peat composed of rotten mosses at bamboo wood, timber and straw, because the accessory substance-gasifying biomass liquid that produces, never find its purposes and become refuse, many producers do not take recycling and directly enter in the atmosphere it, and environment has been caused pollution, form easily local acid rain again, and contaminated environment, therefore become the technical barrier of modern production bamboo charcoal, charcoal and the peat composed of rotten mosses.Simultaneously, closely for many years, biopesticide is developed to has market-oriented kind seldom, does not satisfy the needs of the production of modern green and organic farm products far away, especially weed killer herbicide.At present in the weed killer herbicide market of China, go out that to give birth to weed killer herbicide mainly be 10% gyphosate solution and 20-30% paraquat aqua, the latter is because price constantly increases, and use cost constantly increases and causes the domestic market to be difficult to bear high price and be used for outlet more; Though the former price is lower, per hectare is used the amount up to several kilograms but because activity is low, cost of transportation is continuous to be increased and higher packing price because of petrol price rises, and make the market of 10% gyphosate solution more and more littler, and what is more important, glyphosate is because a large amount of long-term use causes the soil compaction phenomenon seriously soil constantly to be degenerated, and the risk of its ecotope constantly increases.
Summary of the invention
In view of problems of the prior art, the objective of the invention is to design the technical scheme of the production method that a kind of biological source herbicide is provided, production cost is low, and the product herbicidal effect that makes is good, and little to environmental influence, to human body safety.
The production method of described biological source herbicide is characterized in that comprising following processing step:
Add gasifying biomass liquid in reactor, the part by weight of pressing gasifying biomass liquid 0.5-5% then adds special assistant, and stirring promptly gets product; Described gasifying biomass liquid is Bamboo vinegar solution, pyroligneous liquor or careless vinegar liquid; Described special assistant is paraquat special assistant SQ8208, HT201, EF8208 or EDW-518, or glyphosate special assistant EF8108, EDW--596 or Ji Xin-904.
The production method of described biological source herbicide, it is characterized in that gasifying biomass liquid adds thermal distillation or fractionation under the situation of normal pressure or decompression, when the weight of concentrate is that original 2-20% stops distillation or fractionation, collect concentrate, add described special assistant again.
The production method of described biological source herbicide is characterized in that described special assistant consumption is the 0.5-3% of gasifying biomass liquid.
The production method of described biological source herbicide is characterized in that described special assistant consumption is the 1-2% of gasifying biomass liquid.

The production method of described biological source herbicide is characterized in that air-distillation or cut point are 100 ℃; The pressure of decompression distillation or fractionation is 0.05-0.1 atmospheric pressure, and temperature is 50-60 ℃.
The production method of described biological source herbicide, the weight that it is characterized in that concentrate is original 4-15%.
The production method of described biological source herbicide, the weight that it is characterized in that concentrate is original 5-10%.
Described paraquat special assistant SQ8208 is contained by Nanjing and opens the production of chemical industry Co., Ltd, HT201 is produced by Huaian Huatai Chemical Industry Co., Ltd., EF8208 is produced by Nanjing, Nanjing petrochemical industry research institute Co., Ltd, and moral prestige medication chemistry Co., Ltd in EDW-518 effluent Northern Ireland produces.Glyphosate special assistant EF8108 is produced by Nanjing, Nanjing petrochemical industry research institute Co., Ltd, and moral prestige medication chemistry Co., Ltd in EDW-596 effluent Northern Ireland produces, and Ji Xin-904 is produced by the Nanjing glad chemical industry of Ji Co., Ltd.
The weed killer herbicide that the production method of above-mentioned biological source herbicide makes can be re-dubbed compound formulation with other weed killer herbicide, is re-dubbed compound formulation as former medicine or preparation with glyphosate, paraquat.(calculate by making stoste, extension rate is smaller or equal to 300 times, and as concentrating stoste to 20%, then extension rate smaller or equal to 300 ÷ 20%=1500 doubly) use and are steriland herbicide under this biological source herbicide high concentration; (calculate by making stoste, extension rate is greater than 300 times, and as concentrating stoste to 10%, then extension rate greater than 300 ÷ 10%=3000 doubly) use and are plant growth regulator under the low concentration.Described biological source herbicide is aqua.Gasifying biomass liquid finishes the waste liquid (being distillate) that the back produces in distillation or fractionation, can collect, and can be used as the purposes of making organic acid or organic acid salt, also can directly use distillate as the washing amenities.
The production method of above-mentioned biological source herbicide, the biological source herbicide that makes has good weeding activity, belongs to steriland herbicide, and Environmental compatibility is good; Gasifying biomass liquid itself derives from the natural biology material, the safety of agricultural product is given birth to height, to people's safety; High concentration kill plants, low concentration can also promote plant growing; The effect of improving the soil; Manufacturing price is equivalent to 40% of 10% gyphosate solution, and herbicidal effect is higher than its 35-50%, be equivalent to 20% of 25% paraquat price, and herbicidal effect is suitable, alternative glyphosate, paraquat; The herbicidal effect that is re-dubbed compound formulation with glyphosate, the former medicine of paraquat or preparation is better than glyphosate, the agent of paraquat list.
Percentage composition is weight percentage in the present specification.
