Abstract

The invention relates to the technical field of environmental treatment, in particular to an alpine region stony desertification ecological restoration method. The alpine region stony desertification ecological restoration method specifically comprises the following steps of preparation of restoration soil dressing, preparation of stony desertification land, spray seeding of the restoration soil dressing and regular maintenance. After the vegetation is sown, the current-year coverage rate is about 75%, the coverage rate is up to about 65% after the vegetation grows for 5 years, the vegetation can fix sandy soil, and water and soil loss is reduced; the vegetation straws contain 32% of heavy metals after being incinerated, by adding a biological humic acid fertilizer, a water-retaining agent, a microbial agent and the polyaspartic acid, a finally prepared soil conditioner has excellent water-retaining property, cold resistance and drought resistance, the soil structure and environment of the alpine and arid region are improved, the growth of plants in the region is promoted, and desertification control is promoted; and acinetobacter can absorb the heavy metals in cells, so that the heavy metals are effectively extracted from the compost, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to an ecological restoration method for rocky desertification in alpine regions. Background technique [0002] When carrying out engineering construction in the alpine regions such as Qinghai and western Sichuan in my country, more attention should be paid to environmental protection and vegetation restoration. Mine ecosystems in alpine regions are very fragile and sensitive to external disturbances. In case of natural disasters or human disturbances, the ecological environment is easily damaged and difficult to restore. In high altitude regions, the climate is cold, the ultraviolet radiation is strong, the temperature difference between day and night is large, and the temperature changes strongly. Severe drought stress, high heavy metal content, and poor soil nutrition lead to a short average growth period and slow growth of plants. Only relying on the natural recov...
