preparation example Construction

[0020] A preparation method of soil disinfectant, comprising the steps of:

[0021] (1) Take 1,2-dichloroethane and add tetramethylurea according to the mass ratio of 8~10:1~3, stir and mix at 25~30°C for 20~30min, then add the mass of 1,2-dichloroethane 10~15% oxalyl chloride, heated up to 55~60°C, stirred and mixed for 2~3 hours, then rotovaped to obtain rotovap;

[0022] (2) Take the rotary evaporator and add acetonitrile at a mass ratio of 2~4:7~10, stir and mix at -1~1°C for 20~30min to obtain liquid A, take dodecylamine and add it at a mass ratio of 1~3:4~7 Acetonitrile, stirred and mixed for 30~40min to obtain liquid B, take liquid B and add liquid A dropwise at a mass ratio of 3~5:2~4, control the dropping time at -2~1°C for 30~40min, and heat up to 70~80 Stir and mix for 10~13 hours at ℃, distill under reduced pressure to obtain a reduced-pressure distillate, take the reduced-pressure distillate and add distilled water in a mass ratio of 1:10 to mix, filter, take the...

Abstract

The invention discloses a preparing method of a soil disinfectant, and belongs to the environment-friendly field. The preparing method comprises the steps that waste dry battery powder is added, calcination and acidolysis of waste batteries are conducted, mercury in the calcinated batteries is removed, a fertilizer is formed through chelation and added into a disinfectant, and a chelation and sulfonation reaction is generated between an acidolysis product and lignin in papermaking black liquid, so that lignin molecules are grafted with sulfonic acid groups; pH of soil is adjusted, meanwhile, manganese takes part in physiological activities of plants, photosynthesis, carbohydrate decomposition and mineral acid metabolism are promoted, accordingly, growth and development of the plants are promoted, nutrients are supplemented for the growth of the plants, soil substrates are activated, and improvement of the sterilization efficiency is facilitated. The problems are solved that currently,a soil disinfectant is low in disinfection efficiency and short in acting time of active disinfection ingredients.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a preparation method of a soil disinfectant. Background technique [0002] The pathogenic bacteria of soil-borne diseases are generally multi-host microorganisms, which can infect several or even hundreds of crops and weeds. They have strong vitality and infectivity, and are recognized by the plant kingdom as one of the most difficult diseases to control. In agriculture and forestry, the quality of soil is the key factor restricting the development of this field. The soil for cultivating crops in agriculture and forestry is composed of clay, sand, organic matter, water, air, etc. Clay accounts for about 40%, and water and air each account for 40%. However, harmful organisms such as bacteria, fungi, viruses, and nematodes also live in the soil, which affect the growth and development of plants, thereby reducing yield and quality, and causing farmers to suffer ma...
