Problems solved by technology

However, after biomass landfill, a large amount of biodegradable gas, liquid and heat are produced, which have a great impact on plant growth. Vegetation restoration requires a process. At present, there is no method for vegetation restoration of biomass landfill sites at home and abroad.

Embodiment 1

[0030] Described biomass landfill vegetation restoration method comprises the steps:

[0031] (1) Planting soil preparation:

[0032] The soil around the landfill should be crushed after removal of sand and gravel, passed through a 1-3 mesh screen, and then burned together with plant branches, weeds, and crop straw. After being smoked and baked, the soil structure and fertility will be improved, forming Peat soil. Common soil, peat soil and decomposed organic matter around the landfill are mixed evenly at a ratio of 3-5:1-2:1 to form planting soil.

[0033] (2) After the biomass landfill, cover the common soil more than 10cm. After one year, spread 2-100 cm of planting soil on the covering soil, and sow herbaceous plant seeds such as teff, goosegrass, zhifengcao, clover or alfalfa when the climate is suitable.

[0034] (3) Excavate (20-30) cm × (20-30) cm × (20-30) cm planting holes according to the plant row spacing (2-3) m × (2-3) m, and fill in 10-20 cm Planting soil on...

Embodiment 2

[0036] Described biomass landfill vegetation restoration method comprises the steps:

[0037] (1) Planting soil preparation:

[0038] The soil around the landfill should be crushed after removal of sand and gravel, passed through a 1-3 mesh screen, and then burned together with plant branches, weeds, and crop straw. After being smoked and baked, the soil structure and fertility will be improved, forming Peat soil. Common soil, peat soil and decomposed organic matter around the landfill are mixed evenly at a ratio of 3-5:1-2:1 to form planting soil.

[0039] (2) After the field is closed, trim the biomass surface to form a slope top and slope surface, and then cover with 30-150cm of soil. Combined with covering soil trimming, spread a layer of planting soil with a thickness of 2 to 100 cm on the soil covered by the biomass landfill. Sow the seeds of herbaceous plants such as teff, goosegrass, cypress, clover or alfalfa when the weather is suitable.

Abstract

The invention discloses a revegetation method for a biomass landfill. The revegetation method includes that planting soil mixed with organic fertilizer and turfy soil is added into a soil layer for planting pioneer plants to change secondary bare land with brushwood and bosk into forests; soil property of biomass-covered soil is improved by utilizing planting soil to guarantee planted plants not prone to death caused by the influence of gas, liquid and energy generated from biomass degradation; and meanwhile revegetation work amount and investment are reduced and soil utilization rate is increased, and harmful environmental effect from soil bareness is reduced.

Description

technical field [0001] The invention belongs to the technical field of greening, and in particular relates to a vegetation recovery method for a biomass landfill. Background technique [0002] With the development of industry and the increase of population, the original vegetation has decreased sharply, and the environment on which human beings depend is deteriorating day by day. Severe water shortages and droughts in large areas have led to desertification; the scale of cities and towns has reduced the arable area. Biomass landfill can not only reduce the carbon dioxide content in the atmosphere, but also after the biomass landfill is closed, in areas with warm climate and abundant rainfall, artificial intervention can quickly restore and form a new vegetation ecosystem; In areas with low biomass, the rotting organic matter in the biomass landfill can improve the soil structure, improve the air permeability and water retention of the soil, and through artificial assisted v...
