Embodiment 1

[0048] A repairing agent for eliminating soil harmful bacteria, prepared according to the following steps:

[0049]S1. Place recovered mustard residue, flavescens residue, green tea residue, isatid root residue, soybean meal, and corn residue in a crushing grinder for grinding, and sieve to obtain a powder with a mesh size of 20 to 100 mesh; Placed under the ultraviolet disinfecting lamp respectively, the radiation dose is 100μW / cm 2 , the irradiation time is 0.5h, take it out for use;

[0050] S2. Weigh 100g mustard dregs powder, 100g flavescens dregs powder, 100g green tea dregs powder, 100g isatis root dregs powder, 400g soybean meal dregs powder and 150g corn dregs powder; stir and mix the above dregs powder, and continue to add distilled water until The measured water content of the culture medium is 40%, while adding ammonium nitrate or sodium bicarbonate to adjust the pH value of the culture medium so that the pH value of the culture medium is 6;

[0051] S3. Weigh 16g...

Embodiment 10-20

[0056] A restorative agent for eliminating harmful soil bacteria. The difference from Example 8 is that the formulation of the culture medium in the repair agent is different and the inoculum amount of the microbial bacterial solution is different. The specific formulation is shown in Table 2 below.

Abstract

The invention relates to the technical field of soil remediation, and particularly discloses a remediation agent for eliminating harmful bacteria in soil and a preparation method of the remediation agent. The remediation agent is prepared from the following raw materials: leaf mustard residue powder, radix sophorae flavescentis residue powder, tea residue powder, radix isatidis residue powder, soybean meal, corn grit and a microbial bacterial liquid; and the microbial bacterial liquid is prepared by compounding trichoderma with the concentration of 16 to 28 g / L, streptomyces with the concentration of 16 to 28 g / L, bacillus with the concentration of 16 to 28 g / L and pseudomonas with the concentration of 16 to 28 g / L. When the prepared remediation agent is put into soil, active substances contained in the medicine residue powder eliminate part of harmful bacteria in the soil, strains in the microbial liquid rapidly proliferate in the soil, and the concentration of the harmful bacteria in the soil is reduced through the competitive effect, so that the flora structure of the soil is improved, and the crop yield is increased.

Description

technical field [0001] The application relates to the technical field of soil remediation, more specifically, it relates to a remediation agent for eliminating harmful soil bacteria and a preparation method thereof. Background technique [0002] In recent years, the biological pollution of farmland soil in my country has become increasingly serious. Improperly treated domestic sewage, human and animal feces, medical sewage containing pathogens, and industrial wastewater pollute water bodies such as rivers and lakes. Farmers use polluted water to irrigate farmland, causing infectious bacteria and pathogenic bacteria to be brought into farmland soil through the above channels, destroying soil cultivation. The microbial colony environment in the upper layer, and then the number of harmful bacteria in the soil (such as Pythium, Anthracnose, Fusarium, and pathogenic bacteria that can be transmitted to animals by attaching to plants) surges, the flora imbalance, and finally the gr...
