Method for governing red soil strongly-eroded slope

Abstract

The invention relates to a method for governing a red soil strongly-eroded slope. The method comprises the following steps that (1) horizontal furrow groups are dug in a red soil strongly-eroded slope surface along all contour lines, each horizontal furrow group comprises multiple horizontal furrows, and the cross section of each horizontal furrow is trapezoid; (2) planting holes are dug between two adjacent horizontal furrows in the same horizontal furrow group, and the cross section of each planting hole is trapezoid; (3) shrubs and grass are planted in the horizontal furrows, and grass is planted in the planting holes; (4) shallow furrows are dug in the same horizontal furrow group, and water and soil conservation grass seeds are evenly sowed in the shallow furrows to form horizontal grass band chains; (5) after the environment of the strongly-eroded slope is improved one year later, trees are then planted in the horizontal furrows and the planting holes. The method is applied to water and soil loss governance and governance of ecological environment of vegetation recovery of the red soil strongly-eroded slope, water storage and soil protection performance of the slope is increased, the ecological environment good for the vegetation recovery is created, and the governance effect of a red soil strongly-eroded area is improved.

Description

technical field [0001] The invention relates to a method for controlling red soil intensity erosion slope land. Background technique [0002] In the red soil region of southern my country, the granite parent material has a high content of coarse grains, loose soil structure, poor corrosion resistance, and easy to cause soil erosion. When the vegetation on the ground is destroyed, the soil is exposed and is directly washed by the slope runoff. Long-term erosion causes most of the topsoil on the slope to be lost. The core soil is exposed, and some even erode to the parent material layer. Low fertility, high degree of dryness and heat, and natural recovery of vegetation are extremely difficult, which has become an important bottleneck restricting local social and economic development. [0003] Traditional soil erosion control in red soil areas mostly adopts biological measures or engineering measures. Engineering measures include contour ditches, bamboo ditches, horizontal ter...

Problems solved by technology

However, on slopes where red soil is strongly eroded, especially where long-term water and soil erosion has resulted in many coarse crystal particles, the surface temperature is high, and the soil is barren. Biological measures or engineering measures alone are not effective in controlling water and soil loss, and it is difficult to restore vegetation.
