Problems solved by technology

Field surveys found that the areas in southern Jiangxi seriously affected by the mining of ion-type rare earth mines have loose soil, severe soil desertification, and the phenomenon of no grass growing. During the rainy season in the south, the abandoned rare earth mines in southern Jiangxi are prone to water and soil erosion, resulting in a large number of abandoned slopes. Unstable slopes, exposed ground, and lack of vegetation cause serious geological disasters such as subsidence, landslides, and landslides, which seriously restrict and hinder regional agricultural and social development

Embodiment 1

[0028] A repair material for ion-type rare earth tailings area, which is composed of arbuscular mycorrhizal fungi and paspalum, wherein the type of arbuscular mycorrhizal fungi is Glomus cryptoglia, purchased from the Institute of Plant Nutrition and Resources, Beijing Academy of Agriculture and Forestry Sciences, The strain number is 1511C0001BGCAM007; paspalum seeds were purchased from the Scarecrow Agricultural Park in Xinyu City, Jiangxi Province.

[0029] The propagation method of arbuscular mycorrhizal fungi is as follows:

[0030]The seedlings of arbuscular mycorrhizal fungi infecting host plants are propagated and cultivated. The host plant is Sudan grass. The substrate for propagation is red soil, coarse sand and fine sand mixed in a mass ratio of 3:1:1. The propagation substrate was sterilized at 121°C for 2 hours. First sow the seeds of sudan grass in the sterilized propagation medium, take out the seedlings after 2 weeks, rinse the roots, and then evenly inoculate...

Embodiment 2

[0035] A repair material for ion-type rare earth tailings area, which is composed of arbuscular mycorrhizal fungi and paspalum. The species number is 1511C001BGCAM0010; paspalum was purchased from the Scarecrow Agricultural Park in Xinyu City, Jiangxi Province.

[0036] The propagation method of the arbuscular mycorrhizal fungus and the restoration method of the ionic rare earth tailings area are the same as in Example 1, except that the type of arbuscular mycorrhizal fungus is Glomus mosesi.

Embodiment 3

[0038] A repair material for ion-type rare earth tailings, consisting of arbuscular mycorrhizal fungi and paspalum, wherein the type of arbuscular mycorrhizal fungi is Glomus intrarhizogi, purchased from the Institute of Plant Nutrition and Resources, Beijing Academy of Agriculture and Forestry Sciences, The strain number is 1511C0001BGCAM0030; paspalum was purchased from the Scarecrow Agricultural Park in Xinyu City, Jiangxi Province.

[0039] The propagation method of the arbuscular mycorrhizal fungus and the restoration method of the ionic rare earth tailings area are the same as in Example 1, except that the type of the arbuscular mycorrhizal fungus is Glomus intrarhizogi.

Abstract

The invention provides a repairing material, a repairing method and application of an ionic rare earth tailing area, and belongs to the technical field of ecological restoration. The invention provides a repairing material for an ionic rare earth tailing area. The repairing material comprises arbuscular mycorrhizal fungi and pioneer plants, wherein the types of the arbuscular mycorrhizal fungi comprise one or more of glomus intraradices, glomus mosseae and Paraglomus occultum. The types of the pioneer plants comprise one or more of paspalum, ramie and awn. The repairing material provided by the invention has the characteristics of high plant restoration success rate, excellent effect, capability of obviously reducing the water and soil loss rate and the like when being applied to restoration of the ionic rare earth tailing area, and has a good vegetation ecological restoration effect on the ionic rare earth waste mining area in the rainy region in the south; the invention is suitable for rapid treatment of rare earth tailing waste land in southern rainy regions.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a restoration material, restoration method and application of an ionic rare earth tailings area. Background technique [0002] Ionic rare earths are national strategic resources, non-renewable, and are widely used in national defense construction and high-tech fields. Gannan, Jiangxi Province is rich in ionic rare earth resources, and is known as the "rare earth kingdom" in China. Ganzhou City, Jiangxi Province has 30% of the country's ionic rare earths, and is currently attracting attention at home and abroad. Mining of rare earths in southern Jiangxi began in the 1970s and 1980s, and roughly experienced three mining processes: pool leaching, heap leaching, and in-situ leaching. Rare earth mining has created a series of ecological and environmental problems such as vegetation and land resource destruction, water and soil pollution, etc. while creating...
