Rock-desertification ecological restoration method

Abstract

The invention discloses a rock-desertification ecological restoration method. The method includes the following steps of 1, rock-desertification matrix collating, 2, microalga inoculating, 3, herbaceous plant planting, 4, maintenance managing, and 5, bush and arbor planting. Rock-desertification matrix collating includes the steps of 1, collating terrain, and 2, replacing local soil with soil removed from other places. Terrain collating includes the steps of 1, removing pumice stones and dangerous rock bodies, 2, leveling slashes, and 3, protecting side slopes. Microalga inoculating includes the steps of 1, selecting algae species, 2, cultivating the algae species, 3, preparing algae powder and 4, conducting manual rock-desertification inoculation on microalgae. Herbaceous plant planting includes the steps of 1, grass seed selecting, 2, ground treating, 3, fertilizer applying, 4, seed sowing, and 5, soil covering. Bush and arbor planting includes the steps of 1, tree seed configuring, and 2, seed sowing. The rock-desertification ecological restoration method integrates a microalga biotechnology, an ecological soil restoration technology and an ecological forestry restoration technology, and a new technical method is provided for scientific and efficient rock-desertification treatment.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method for ecological restoration of rocky desertification. Background technique [0002] Rocky desertification is the abbreviation of "rocky desertification". The main cause of rocky desertification is serious soil erosion, and the main factor leading to rocky desertification is human activities. In recent years, the ecological environment of our country has been greatly damaged. In some areas such as rocky mountains and karsts, due to serious soil erosion, the problem of rocky desertification is very prominent. For a long time, the natural vegetation has been continuously destroyed, and a large area of ​​steep slopes has been opened up, causing the surface to be exposed. In addition, the soil layer in the karst rocky mountainous area is thin, the bedrock is exposed shallowly, and the erosion force of the heavy rain is strong. The phenomenon of "rocky desertif...

Problems solved by technology

[0004] The main problem with the above method is that the soil on the rocky desertification land mainly depends on foreign soil, and foreign soil is likely to cause wind and sand to be blown away when it encounters strong winds. At the same time, after being washed by rainwater, water and soil continue to be easily lost.

often difficult to succeed

At the same time, this method has a single technology, and the rocky desertification land is slow or difficult to form soil.
