Embodiment 1

[0029] A kind of microbial soil remediation agent, is made up of each material of following mass parts:

[0030]

[0031] The microbial soil remediation agent of the present invention remediates the soil method, and described remediation soil method comprises the following steps:

[0032] Sa uses a rotary tiller to level the land to keep the soil air-permeable;

[0033] Sb is at 60% of soil moisture, 30 ℃ of ambient temperature, do sunshade measure well, the microbial soil remediation agent of the present invention is diluted with water by the mass ratio of 1:300, the microbial soil remediation agent after dilution is pressed 80ml / mu Spray evenly into the soil;

[0034] After Sc 60 days, the soil that step Sb has sprayed microbial soil remediation agent is evenly sprayed once microbial soil remediation agent again, and consumption and usage are identical with step Sb.

Embodiment 2

[0036] A kind of microbial soil remediation agent, is made up of each material of following mass parts:

[0037]

[0038]

[0039] The microbial soil remediation agent of the present invention remediates the soil method, and described remediation soil method comprises the following steps:

[0040] S1 detects the soil and measures the soil pH value, inorganic salt and nitrogen content;

[0041] S2 leveling the field and clearing the cultivated land crops;

[0042] S3 according to the detection result of step S1, adjust soil pH value to 5-9 with lime, plant ash or organic fertilizer, apply organic fertilizer to ensure that nitrogen content in the soil is 140-225mg / kg, phosphorus content is 57-100mg / kg, potassium content 106-150mg / kg, if the test result of step S1 shows that the pH value, nitrogen content, phosphorus content and potassium content are all within the required range, step S3 is omitted;

[0043] S4 Till the land with a rotary tiller to keep the soil air-perm...

Abstract

In order to solve the problem that conventional soil remediation technology has a single remediation function, can only remedy soil hardening and salinization and cannot reduce the content of heavy metal, the invention provides a microbial soil remediation agent and a soil remediation method. The microbial soil remediation agent is composed of the following substances, by mass: 1-3 parts of bacillus subtilis, 1-5 parts of acidithiobacillus ferooxidans, 1-2 parts of cyanobacteria, 1-2 parts of sulfate reducing bacteria, 1-2 parts of desulfovibrio desulfuricans, 1-2 parts of trichoderma, 2-4 parts of penicillium spinulosum, 2-5 parts of bacillus coagulans, 3-5 parts of rhodopseudomonas palustris, 2-5 parts of garcinococci, and 2-5 parts of cold salt tolerant gingivalis. The microbial soil remediation agent and the soil remediation method of the invention can effectively reduce the heavy metal content of oil, adjust the pH of the soil, reduce the cadmium content of crops and increase theyield of the crops.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a microbial soil remediation agent and a soil remediation method thereof. Background technique [0002] my country's agricultural land is forced to pursue a high yield per mu, and a large amount of chemical fertilizers and pesticides are used. The soil is seriously polluted, not only the pesticide residues and harmful metals exceed the standard, the soil is compacted, and the lack of organic matter is common. Soil-borne diseases are common; the crops cultivated from such soil will inevitably be seriously polluted, endangering food safety and the health of the general public . [0003] Most of the existing microbial agents exist in the form of microbial fertilizers, and their main functions are to help crops resist and prevent diseases, improve the effectiveness of organic fertilizers, provide or activate nutrients, and improve crop quality. And most of the restorative ...
