Method for repairing mining area vegetation and soil by using Ficus tikoua bur

Abstract

The invention discloses a method for repairing mining area vegetation and soil by using Ficus tikoua bur and belongs to the field of vegetation repair. The method comprises the following steps that the Ficus tikoua bur is subjected to greenhouse seedling growing in a cutting manner; Ficus tikoua bur seedlings which survive after seedling growing are planted to the mining area, and early stage growth management of the Ficus tikoua bur is done; or cutting or stem burying of the Ficus tikoua bur is directly performed in the mining area, and the purpose of growing the Ficus tikoua bur in the mining area can be realized as well; after the mining area is covered with the Ficus tikoua bur, Lolium perenne seeds and / or ciliate desert-grass spores are sown. According to the method for repairing the mining area vegetation and soil by using the Ficus tikoua bur, the repair effect to the vegetation and heavy metal contaminated soil is excellent, and great social benefits and economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of vegetation restoration, in particular to a method for restoring vegetation and soil in mining areas by using wild sweet potatoes. Background technique [0002] Wild sweet potato, also known as sweet potato bubble, has milk in the whole plant and is more than 10 meters long. It grows on the ground and tends to grow fibrous adventitious roots when it touches the ground. It looks like a giant centipede, so it is also called crawling centipede. Wild sweet potatoes have the characteristics of cold resistance, drought resistance, shade resistance, barren resistance, and water and humidity resistance. Even if they are planted in the sandstone or stone gaps where there is no grass, they will be luxuriant and green; whether it is hot summer or summer. In the winter of ice and snow, it still grows on the hills exposed to the scorching sun or under the ancient forests. The leaves are always green and green, and they are full ...

AI Technical Summary

Problems solved by technology

[0003] The environment in mining areas is often relatively harsh, especially tailings ponds generally have a high concentration of heavy metals, which poses certain difficulties for the restoration of vegetation in mining areas and the restoration and protection of heavy metal-contaminated soil in mining areas

At present, there is no efficient and ideal repair method
