Embodiment 1

[0029] The greening method of abandoned mine land includes the following steps:

[0030] S1. First level the mine wasteland, plant alder in March, and then plant perennial wormwood;

[0031] S2. From the second year of planting, harvest perennial wormwood in May every year, leave 2 cm of stubble, and lay the harvested perennial wormwood on the mine wasteland with a thickness of 1 cm; when the aboveground part of alder grows to a height of 100 cm, stop Harvest perennial wormwood.

Embodiment 2

[0033] The greening method of abandoned mine land includes the following steps:

[0034] S1. First level the mine wasteland, plant alder in June, and then plant perennial wormwood;

[0035] S2. From the second year of planting, harvest perennial wormwood in August every year, leave a stubble of 6 cm, and lay the harvested perennial wormwood on the mine waste land with a thickness of 5 cm; when the aboveground part of the alder grows to a height of 200 cm, stop Harvest perennial wormwood.

Embodiment 3

[0037] The greening method of abandoned mine land includes the following steps:

[0038] S1. First level the abandoned mine site, plant alder in April, and then plant perennial wormwood;

[0039] S2. From the second year of planting, harvest perennial wormwood in July every year, leave 4cm stubble, and lay the harvested perennial wormwood on the mine wasteland with a thickness of 3cm; when the aboveground part of alder grows to a height of 150cm, stop Harvest perennial wormwood.

Abstract

The invention discloses a re-greening method of an abandoned land of a mine. Firstly, site leveling is carried out on the abandoned land of the mine, alders are planted from March to June, and then perennial artemisia argyi is planted; starting from the second year of planting, the perennial artemisia argyi is harvested from May to August every year, stubbles with the heights of 2-6 centimeters are reserved, the harvested perennial artemisia argyi is laid on the abandoned land of the mine, and the laying thickness is 1-5 centimeters; when the overground parts of the alders grow to 100-200 centimeters, harvesting of the perennial artemisia argyi is stopped. The re-greening method of the abandoned land of the mine has the advantages that the alders and the perennial artemisia argyi are planted to achieve the greening effect, the harvested artemisia argyi and pruned alder branches and leaves which can serve as green manure cooperate with the carbon fixation of the alders, which can effectively improve the soil fertility of the abandoned land of the mine, thereby promoting re-greening of the abandoned land of the mine.

Description

technical field [0001] The invention belongs to the technical field of mine abandoned land restoration, and in particular relates to a greening method of mine abandoned land. Background technique [0002] Abandoned mine land refers to the land damaged by mining activities and cannot be used without treatment, including exposed mining rock mouths, waste soil (stone, slag) piles, coal gangue piles, tailings ponds, abandoned factory buildings and other construction lands. [0003] Goaf subsidence land and delineate waste land with hidden dangers of goaf subsidence, etc. The surface and mountain structure of abandoned mines are severely damaged, the original natural vegetation is completely destroyed, and the soil is high in heavy metals and poor in nutrients. It is an extremely degraded ecosystem. [0004] The abandoned land produced in the development and utilization of mineral resources has seriously affected the ecological security of the country, threatening the survival o...
