Planting method for mining collapse areas

Abstract

The invention discloses a planting method for mining collapse areas, which comprises: preparing nutritional soil; filling the nutritional soil into seedling raising bags; digging conical seedling holes for holding the seedling raising bags; and placing the seedling raising bags into the seedling holes with the opening of the seedling raising bags downward, and filling seeds into the seedling raising bags. The seedlings raised by the method can be directly planted in the mining collapse areas to be greened, and the problem of low transplant survival rate of seedlings is solved. In addition, the water consumption of the planting method is low and pipe maintenance cost is low. When the planting method of the invention is adopted, the salinization of soil due to watering is avoided.

Description

technical field [0001] The invention relates to a planting method used in coal mining subsidence areas. Background technique [0002] The area bordering the desert and the Loess Plateau has sparse vegetation and a high degree of desertification. It is an arid and semi-arid area with a fragile ecological environment. In recent years, the subsidence caused by large-scale coal mining activities in mining areas has had a significant impact on the surface of these areas, causing a series of changes in the surface morphology, such as subsidence, fractures, cracks, and subsidence steps. Buildings, roads, etc. will cause certain damage, which may cause different degrees of damage to the local ecological environment, further deteriorating the originally fragile ecological environment. Therefore, a large number of artificial forestation and other ecological construction work is required within the scope of the mining area. Vegetation, as the main natural factor on the surface of min...

AI Technical Summary

Problems solved by technology

[0005] 1. The survival rate of transplanted seedlings in the subsidence area is low

Many tree species such as sorbifolium sorbifolium, apricot, wild jujube, etc. have a very low survival rate after transplanting

Especially sorbifolium sorbifolium, although sorbifolium sorbifolium is one of the ancient tree species, and it has strong drought resistance and good economic prospects, but the survival rate of transplanting in coal mining subsidence areas is extremely low, and coal mining in arid and rainless mining areas In subsidence areas, it is particularly important to increase the survival rate of X. sorbifolium

[0006] 2. Due to the harsh conditions in the coal mining subsidence area, the conventional seed broadcasting method is not feasible

The current methods of planting seedlings in nutrition cups and transplanting in the rainy season have complicated technical requirements and high requirements for time points. All transplanting needs to be carried out in heavy rainy days, making it difficult to carry out greening work

[0007] 3. The cost of greening is high and the consumption of water resources is large

Since the underground water resources in the coal mining subsidence area have basically been completely lost, the water for greening can only be drawn by water trucks to distant living quarters or riversides, and the roads are inconvenient

Coupled with the drought in spring, the amount of evaporation during transplanting is large, and the water consumption for irrigation is large, which greatly increases the cost of greening
