A kind of ecological control plant sowing method

Abstract

The invention discloses a seed sowing method for ecological management plants. The seed sowing method is mainly used for sowing seeds of the reclamation plants in arid area open pit coal mine soil-discharging fields, and mainly comprises the steps that strip mine high-quality soil and organic fertilizer are mixed to configurate nutrient soil, the nutrient soil is disinfected, sterilized and watered to form plant seed sowing base blocks, plant seeds which need to be sown are sown into soil on the surface layer of the plant seed sowing base blocks or water leakage planting holes, the bottom and periphery of the plant seed sowing base blocks are filled with earth surface soil and high-quality soil of a seed sowing site, which are used as the base soil, high-quality soil fertilizer is concentrated to the roots of the plants, clay fertilizer resources are concentratedly and efficiently utilized, the soil environment suitable for continuous growing of the plants is formed, the growth of the plants is accelerated, the seed, water and soil loss is avoided, and the ecological management quality in diggings is improved. Two-year manual cultivation is needed for grass planting, the vegetation coverage rate is improved by 5 percent to10 percent, and the survival rate of trees and shrubs reaches 80 percent to 85 percent after three-year manual cultivation.

Description

technical field [0001] The invention relates to a planting method for ecological control plants in arid grassland areas, in particular to a planting method for reclamation plants in open-pit coal mine dumps and mining areas in grassland areas. Background technique [0002] At present, the sowing of known open-pit coal mine dumps and reclamation plants in mining areas is carried out by directly covering the surface soil and sowing seeds. Due to the shallow surface soil layer in grassland areas, the thickness of the surface soil in most areas is between 20-30cm. This limited soil resource is lost and wasted in a large amount during the process of earthwork stripping, transportation, and covering to the dump site and mining area. As a result, the surface soil in the stripping area of ​​the open-pit mining area is not enough to cover the green area, and most of it should be reclaimed. Due to the lack of surface soil for reclamation and planting in the greening area, the plants a...

[0002] At present, the sowing of known open-pit coal mine dumps and reclamation plants in mining areas is carried out by directly covering the surface soil and sowing seeds. Due to the shallow surface soil layer in grassland areas, the thickness of the surface soil in most areas is between 20-30cm. This limited soil resource is lost and wasted in a large amount during the process of earthwork stripping, transportation, and covering to the dump site and mining area. As a result, the surface soil in the stripping area of ​​the open-pit mining area is not enough to cover the green area, and most of it should be reclaimed. Due to the lack of surface soil for reclamation and planting in the greening area, the plants are difficult to survive, the soil erosion is serious, and the land is exposed to sand and rocks, which leads to low quality of vegetation reclamation projects in the mining area, and the source of pollution cannot be effectively controlled. The quality of pasture around the mining area has declined. degradation
