Embodiment 1

[0016] The composition weight percentage of the soil disinfection solution is: 15-29% of 3-dichloropropene solution, 13-32% of chloropicrin solution, 13-19% of trichloropicrin, 11-22% of dacenolon, carboxymethyl Cellulose 2-6%, the sum of the above components by weight is 100%;

[0017] The soil disinfection solution is sprayed and adsorbed on the activated carbon at normal temperature to make the soil disinfection solution into solid granules, and then the soil disinfection granules are mixed with non-antagonistic herbicide granules to obtain a finished product.

Embodiment 2

[0019] The composition weight percentage of soil disinfection solution is: 24-27% of 3-dichloropropene solution, 28-32% of chloropicrin solution, 16-18% of trichloropicrin, 17-22% of dacenolon, carboxymethyl The sum of 2-3% cellulose and the above components is 100% by weight.

Embodiment 3

[0021] The composition weight percentage of the soil disinfection solution is: 26-28% of 3-dichloropropene solution, 29-32% of chloropicrin solution, 15-19% of chloropicrin, 11-21% of trichloropicrin, 11-21% of carboxymethyl The sum of 5-6% cellulose and the above components by weight is 100%.

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 [0001] The invention relates to the technical field of agricultural supplies, in particular to a preparation method of a soil disinfection and herbicide mixture. Background technique [0002] At present, there are two types of herbicides used in agricultural production in my country: one is soil treatment agents, and the other is stem and leaf treatment agents. The weed control method of soil treatment agent is to spray the herbicide on the soil surface before the weeds emerge, and then mix the herbicide into the soil through the soil mixing operation to establish a closed layer of herbicide to avoid or Reduce the volatilization and photolysis of herbicides. The mixed soil application method can make the agent absorbed by weed roots, coleoptiles and hypocotyls, so as to control weeds, improve the efficacy and prolong the duration of effect. The application method of this herbicide is the same as that of the soil disinfectant 1,3-dichloropropene and...
