Embodiment 1

[0040] The Glomus terrescens preparation comprises Glomus terrescens spores, Mycelia of Glomus terrescens, root segments of host plants and rhizosphere soil of host plants. The Glomus terrestris preparation is a granule preparation, the number of spores contained is 5 / g, and the host plant is Bermudagrass, and the preparation is mainly used in repairing antimony-contaminated soil.

[0041] The specific steps for the application of Glomus terrescens preparations in remediation of contaminated soil include:

[0042] (1) Use 5% H 2 o 2 The solution disinfects the bermudagrass, and the disinfection time is 5 minutes;

[0043] (2) Sterilize 20 g of the original root soil of bermudagrass with high-pressure steam at a pressure of 0.12 MPa, and then take 5 g of Glomus terrescens preparation and mix it with the original root soil evenly as the culture soil;

[0044](3) Surround the bermudagrass root system with the culture soil and plant it in the soil polluted by antimony. The plan...

[0048] The Glomus terrescens preparation comprises Glomus terrescens spores, Mycelia of Glomus terrescens, root segments of host plants and rhizosphere soil of host plants. The Glomus terrescens preparation is a granular preparation, the number of spores contained is 100 / g, and the host plant is Bermudagrass, and the preparation is mainly used in repairing antimony-polluted soil.

[0049] The specific steps for the application of Glomus terrescens preparations in remediation of contaminated soil include:

[0050] (1) Use 10% H 2 o 2 The solution disinfects the bermudagrass, and the disinfection time is 20 minutes;

[0051] (2) Sterilize 250 g of the original root soil of bermudagrass with high-pressure steam at a pressure of 0.13 MPa, and then take 40 g of Glomus terrescens preparation and mix it with the original root soil evenly as the culture soil;

[0052] (3) Surround the bermudagrass root system with the cultivation soil, and plant it in the soil polluted by antimony....

Embodiment 3

[0056] The Glomus terrescens preparation comprises Glomus terrescens spores, Mycelia of Glomus terrescens, root segments of host plants and rhizosphere soil of host plants. The Glomus terrescens preparation is a granular preparation, the number of spores contained is 50 / g, and the host plant is Bermudagrass, and the preparation is mainly used in repairing antimony-polluted soil.

[0057] The specific steps for the application of Glomus terrescens preparations in remediation of contaminated soil include:

[0058] (1) Use 7% H 2 o 2 The solution disinfects the bermudagrass, and the disinfection time is 10 minutes;

[0059] (2) Sterilize 150 g of the original root soil of bermudagrass with high-pressure steam at a pressure of 0.14 MPa, and then take 20 g of the preparation of Glomus terrestris and mix it with the original root soil evenly as the culture soil;

[0060] (3) Surround the bermudagrass root system with the cultivation soil and plant it in the soil polluted by antim...

Abstract

The present invention proposes a Glomus terrescens preparation, which comprises Glomus terrescens spores, mycelia of Glomus terrescens, root segments of host plants and rhizosphere soil of host plants. The preparation is a granule preparation, and the spores contained therein The number is 5‑100 pieces / g. The present invention also proposes the application of the above-mentioned Glomus terrestrialis preparation in remediating polluted soil. The preparation is mainly used in remediating soil polluted by heavy metals. The application has the following effects: promoting the growth of plants, increasing the biomass of plants, improving Improve the nutritional status of plants, improve their tolerance to toxic substances, significantly increase their adsorption of toxic substances, and improve the efficiency of soil restoration.

Description

technical field [0001] The invention relates to soil remediation technology, in particular to a surface glomus preparation and its application in remediating polluted soil. Background technique [0002] Antimony (Sb) is a toxic carcinogenic element, its content in the earth's crust is about 0.2-0.3mg / kg, and the soil background value is about 0.3-2.3mg / kg. Antimony and antimonides have been proven to be a class of genotoxic substances and carcinogenic to the human body. They are also a global pollutant with long-distance transmission characteristics. At present, the US Environmental Protection Agency and the Council of the European Community have Antimony is listed as a priority pollutant. With the development of modern industry, the demand for antimony has increased sharply. Most of the antimony released into the environment is enriched and transmitted in terrestrial ecosystems, and accumulates in the human body through the food chain, which eventually affects the metaboli...
