Method for culturing vegetation in Karst landform region

Abstract

The invention discloses a method for culturing vegetation in a Karst landform region. The method comprises the steps of borrowed soil backfilling, retaining wall building, land preparation, base fertilizer application, seedling selection, planting and management, and can be used for effectively improving the survival rate of vegetation planted in the Karst landform region; the planted lands of different shapes can be prepared according to the specific conditions of the Karst landform, so that the practicability of the method is improved; through arranging retaining walls, soil is prevented from running off, a good growing environment is provided for the growth of vegetation, and the ecological environment of the Karst landform region is improved.

Description

technical field [0001] The invention belongs to the field of controlling rocky desertification of karst landforms, and in particular relates to a method for cultivating vegetation in karst landforms. Background technique [0002] Rocky desertification of karst landform is a harsh ecological environment in which the rocks are completely exposed and no grass grows after the ecological environment in the rocky mountain area is destroyed. Vegetation restoration in rocky desertification areas is difficult to manage and ecological restoration is difficult. In particular, the ecological restoration of karst rocky desertification is more difficult. [0003] For a long time, in most karst areas, due to the interference of firewood harvesting, grazing, and burning, the vegetation has been repeatedly destroyed, the vegetation resources are scarce, the ecological environment is fragile, natural disasters are frequent, the upper layer is shallow, soil erosion is extremely serious, and r...

Problems solved by technology

[0003] For a long time, in most karst areas, due to the interference of firewood harvesting, grazing, and burning, the vegetation has been repeatedly destroyed, the vegetation resources are scarce, the ecological environment is fragile, natural disasters are frequent, the upper layer is shallow, soil erosion is extremely serious, and rocks are exposed in some areas. The rate is increasing year by year, causing the rocky desertification site to become more and more serious, making it very difficult to restore vegetation

Although there is abundant precipitation in the karst area, due to the uneven distribution of precipitation in the basin, shallow soil layer, discontinuous soil, low soil water holding capacity and serious seepage, it is easy to cause seasonal drought in the soil, even in rainy During the growing season, there is often a dry period when the evaporation is greater than the precipitation, which largely affects the recovery of vegetation.

Especially in rocky desertification areas with a high degree of degradation and a large area of ​​bare rock, the vegetation system is very fragile, the ability of the community to resist external disturbances is very low, and the self-repair ability after damage is poor, and the natural restoration of habitat and vegetation is extremely difficult.
