Abstract

The invention discloses a method for preventing and controlling water and soil loss, which comprises the following steps of: (1) spraying herbicide to a slope surface to kill weeds; (2) the slope surface is trimmed; (3) preparing a component A, a component B and a component C; (4) preparing a component D and a component E; (5) preparing a component F and a component G; (6) mixing the rest component A, the rest component B, the rest component C, the rest component D, the rest component E, the rest component F and the rest component G; and (7) sowing perennial herbaceous plants and perennial shrubs, and cultivating. The method can effectively solve the problem of water and soil loss of the slope, especially the problem of water and soil loss caused by geological conditions such as granite, limestone and purple sand shale.

Description

technical field [0001] The invention relates to the technical field of water and soil loss control, in particular to a method for preventing and controlling water and soil loss. Background technique [0002] Soil erosion refers to the simultaneous loss of water and soil due to natural or human factors. The main reasons are the large slope of the ground, improper land use, destruction of ground vegetation, unreasonable farming techniques, loose soil, deforestation, overgrazing, etc. [0003] The harm of water and soil loss is mainly manifested in: the soil cultivation layer is eroded and destroyed, which makes the land fertility gradually exhausted; silting up rivers, channels and reservoirs, reducing the benefits of water conservancy projects, and even causing floods and droughts, seriously affecting industrial and agricultural production; Agricultural production in mountainous areas and downstream rivers pose serious threats. [0004] Rainfall is a prerequisite for soil e...
