Embodiment

[0039] Embodiment: make one kilogram of soil disinfection herbicide mixture.

[0040] 1. Material preparation: Weigh 100g of alachlor 15% granules, 540g of activated carbon, 234g of liquid 1,3-dichloropropene, and 126g of liquid chloropicrin.

[0041] 2. Adsorption: Put activated carbon into a glass bottle with a rubber cap, inject liquid 1,3-dichloropropene and liquid chloropicrin into the glass bottle with an airtight syringe, and shake at a temperature of 30°C 5 hours.

[0042] 3. Detection: Put the glass bottle into a sealed box equipped with a gas probe, open the rubber cover of the glass bottle, and the gas probe shows that there is no chloride in the box, that is, the adsorption is over.

[0043]4. Weighing: Pour out the activated carbon after adsorption and weigh it. If the allowable difference of 900g of soil disinfection granules is within the specified range, it is qualified.

[0044] 5. Mixing: Put 900g of alachlor 15% granules and 40% soil disinfection granules ...

Abstract

The invention relates to a mixture for soil disinfection and weeding. The soil disinfectant of the invention is 1,3-dichloropropene and chloropicrin, adsorbents are active carbon and kieselguhr, and a weed killer is alachlor. The mixture for soil disinfection and weeding is prepared by the following steps: firstly, sealing, spraying and adsorbing the liquid 1,3-dichloropropene and chloropicrin in proportion at normal temperature to form particles; and then mixing and combining with the alachlor particles in proportion to form a new pesticide with two functions of soil disinfection and weeding. Soil disinfection and weeding are completed once, thus reducing the pesticide cost and improving the labor efficiency. The soil disinfectant and the weed killer can play a mutually positive effect, can improve the chemical effect, and reduce the residue of the weed killer in crops. As required, the soil disinfection particles can be mixed with various weeding particles which can not generate antagonism and are effective and safe after combination. The mixture of the invention can be applied to upland fields, paddy fields and protected areas in agricultural production.

Description

technical field [0001] The invention relates to a mixture of soil disinfection and herbicide, which belongs to the technical field of agricultural means of production, and is specifically a new type of pesticide which has two functions of soil disinfection and weed control. 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 metho...
