Embodiment 1

[0030] A preparation method for degrading soil residual organic pesticide polluted soil remediation agent, the specific steps are as follows:

[0031] Raw material ratio (components by weight): 35 parts of attapulgite powder, 2 parts of expanded perlite, 0.5 part of microbial compound bacterial agent, 10 parts of corn flour, and 60 parts of straw powder.

[0032] The microbial agent consists of bacillus and pseudomonas.

[0033] The bacillus is clostridia.

[0034] The straw powder is dried rice straw and crushed by machine, the length is less than 1cm.

[0035] Raw material processing:

[0036] 1. Microbial culture and activation: respectively inoculate Bacillus and Pseudomonas into LB (Luria Bertani) liquid medium containing high-pressure steam sterilization, and carry out aerobic culture at 28-32°C for 2 days to obtain shake flask bacteria kind;

[0037] Two, the bacterial classification in the above-mentioned shake flask is inoculated in the fermentor containing LB liq...

Embodiment 2

[0045] A preparation method for degrading soil residual organic pesticide polluted soil remediation agent, the specific steps are as follows:

[0046] Raw material ratio (components by weight): 45 parts of attapulgite powder, 5 parts of expanded perlite, 0.3 part of microbial compound bacterial agent, 5 parts of corn flour, and 40 parts of straw powder.

[0047] The microbial agent consists of bacillus and pseudomonas.

[0048] The bacillus is bacillus subtilis.

[0049]The straw powder is rice straw waste dried in the sun and crushed by machine, and the length is less than 0.5cm.

[0050] Raw material processing: Stir and mix the compound bacterial agent and corn flour, and then add expanded perlite for further stirring and mixing.

[0051] Add attapulgite and straw powder into a blender and further stir and mix with the above-mentioned mixed material. The obtained mixed dry material is the prepared soil remediation agent for absorbing and degrading organic pesticides.

Abstract

The invention discloses a soil restoration agent adsorbing and degrading organic pesticide. The soil restoration agent comprises the components of, by weight, 35-55 parts of attapulgite powder, 2-10 parts of expanded perlite, 0.1-0.5 part of a microorganism compound microbial inoculum, 1-10 parts of corn powder and 40-60 parts of straw powder. Meanwhile, the invention discloses a preparation method of the restoration agent. The soil restoration agent combines microorganisms, organic materials and natural minerals so as to principally adsorb and degrade organic pesticide in the soil, and meanwhile can reduce nutrient loss and passivate heavy metal. The natural mineral materials used in the formula can adsorb the organic pesticide enriched in the soil, excessive available nutrients and the heavy metal. The soil restoration agent can effectively degrade the organic pesticide in the soil, particularly has obvious restoration effects on facility agricultural soil where vegetables and fruitsare planted for a long time and a large amount of pesticide and fertilizers are applied, and can effectively improve the soil production environment and improve the safety of food.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, in particular to a soil restoration agent for absorbing and degrading organic pesticides and a preparation method thereof. Background technique [0002] Chemical pesticides play a huge role in the prevention and control of crop diseases, pests and weeds, as well as the elimination of hygienic pests and diseases due to their advantages of quick effect, stable properties, convenient transportation, and low price. , can also enter the atmosphere through volatilization and diffusion, causing air pollution or migrating with water into the water body, causing water pollution. Some are chemically stable and last for a long time. A large amount of pesticides are used continuously to accumulate them in the soil. People will seriously threaten human health after eating agricultural products that have accumulated a large amount of pesticides. [0003] According to the survey results of the 2014 Na...
