Abstract
The invention discloses a method for preparing a soil disinfecting and weeding mixture. A soil disinfecting solution comprises the following components in percentage by weight: 15-29% of a 3-dichloropropene solution, 13-32% of a trichloronitromethane solution, 13-19% of chloropicrin, 11-22% of dazomet and 2-6% of carboxymethylcellulose, wherein the sum of the weight ratio of the components is 100%. The method comprises the following steps: spaying the soil disinfecting solution at the room temperature to be adsorbed onto activated carbon to be formed into solid granules, mixing and combining the soil disinfecting granules with weeding granules, which are not antergic, so as to produce the finished product. The soil disinfecting and weeding mixture has strong fume killing capability on imagoes and larvas of pests, can effectively protect plant root systems from being damaged, has no pesticide residue in plants and soil, and can be remained in the soil after the pesticide effect is released to play the function of improving the soil; a user needs not to wear an antigas mask when applying the pesticide, and the transportation, the storage and the use are convenient and safe.
Description
Technical field
The present invention relates to agriculture articles for use technical field, especially a kind of preparation method of mixture for soil disinfection and weeding.
Background technology
At present, the weed killer herbicide used in China's agricultural production has two large types: a class is processing soil treatment agent, and a class is cauline leaf inorganic agent.The management of weeds mode of processing soil treatment agent class is before weeds do not emerge, by herbicide spray in upper soll layer, then by mixed soil operation, weed killer herbicide is mixed in soil, sets up the confining bed of one deck weed killer herbicide, to avoid or to reduce volatilization and the photodissociation of weed killer herbicide.Mixed native dispenser method can make medicament by site absorption such as weeds root, coleoptile and hypocotyls, and then management of weeds, and can improve drug effect and extend the lasting period.The application method of this weed killer herbicide is identical with the application method that chloropicrin carries out soil disinfection with soil disinfection medicament 1,3-dichloropropylene.Under crops continuous cropping planting conditions, soil disinfection and management of weeds are the essential production processes that will carry out, and peasant needs twice dispenser to reach the basic demand of proportion of crop planting to soil.All need regular hour competence exertion effect separately because weed killer herbicide and soil disinfectant are used alone, this just extends the idle periods in soil.Scientifically combine mixed by the weed killer herbicide that antagonism does not occur with soil disinfectant, a dispenser just can management of weeds, and makes crop not be the preparation of a kind of advanced person by the infringement of pathogen and pest control.Weeding and soil disinfection is disposable completes, can also shorten the free time in soil, reduce the drug cost of peasant, raise labour efficiency.This formulation is very favourable to agricultural production, but so far, China does not also have the medicament having soil disinfection and weeding two kinds of functions concurrently of practicality and high efficiency now.
In view of the foregoing, a kind of preparation method of mixture for soil disinfection and weeding is now developed.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of preparation method of mixture for soil disinfection and weeding is provided, all very strong to the adult of insect, larva smoked kill power, can do not encroached on by available protecting root system of plant, and medicament residue is not had in plants and soil, the active carbon adopted is graininess, and active carbon has stronger adsorption function and good slow-release function, stays in soil the effect playing improvement soil after drug effect release; Need not wear a gas mask during dispenser, transport, storage and use all facilitate and safety.
The present invention to achieve these goals, adopt following technical scheme: a kind of preparation method of mixture for soil disinfection and weeding, the assembly percentage by weight of soil disinfection solution is: 3-dichloropropylene solution 15-29%, chloropicrin solution 13-32%, trichloronitromethane 13-19%, dazomet 11-22%, carboxymethyl cellulose 2-6%, above each component by weight ratio sum are 100%;
Soil disinfection solution is sprayed absorption on the activated carbon at normal temperatures, makes soil disinfection solution become solid granular, then soil disinfection particle is combined with the herbicide granule mixture that antagonism does not occur, obtained finished product.
The assembly percentage by weight of soil disinfection solution is: 3-dichloropropylene solution 24-27%, chloropicrin solution 28-32%, trichloronitromethane 16-18%, dazomet 17-22%, carboxymethyl cellulose 2-3%, above each component by weight ratio sum are 100%.
The assembly percentage by weight of soil disinfection solution is: 3-dichloropropylene solution 26-28%, chloropicrin solution 29-32%, trichloronitromethane 15-19%, dazomet 11-21%, carboxymethyl cellulose 5-6%, above each component by weight ratio sum are 100%.
The assembly percentage by weight of soil disinfection solution is: 3-dichloropropylene solution 19-27%, chloropicrin solution 22-32%, trichloronitromethane 14-19%, dazomet 15-21%, carboxymethyl cellulose 2-6%, above each component by weight ratio sum are 100%.
Described soil disinfection particle and the herbicide granule that antagonism do not occur merge in the ratio mixture of 3 to 1.
After finished product being put into the process of drying equipment inner drying, quantitative package, then thing does sunshade thermal insulation process, adopts vacuum packaging mode.
The invention has the beneficial effects as follows: the present invention has soil disinfection and weeding two kinds of functions concurrently, reduce times for spraying, reduce agricultural cost, raise labour efficiency; Composition in intermixture has a positive effect mutually, improves drug effect; Effective reduction, to the poisoning of crop, reduces the medicament residue of weed killer herbicide in crop; Delay generation and the development of herbicide resistance; Spray the method rational technology of absorption, simple and easy to do, show an interesting new approach, production process three-waste free discharge, has no adverse effects to environment.Soil disinfection and weeding is disposable completes, can reduce drug cost, raise labour efficiency.Soil disinfectant and weed killer herbicide have a positive effect mutually, can improve drug effect, reduce weed killer herbicide remaining in crop.As required, soil disinfection granule can not produce antagonism with multiple, in conjunction with after effectively and the herbicide granule mixture of safety.
The present invention is very strong to the adult of insect, larva smoked kill power; can do not encroached on by available protecting root system of plant; and medicament residue is not had in plants and soil; the active carbon adopted is graininess; active carbon has stronger adsorption function and good slow-release function, stays in soil the effect playing improvement soil after drug effect release.Need not wear a gas mask during dispenser, transport, storage and use all facilitate and safety.The present invention dry land, paddy field, protecting field in agricultural production all can be applied.
