The invention discloses a treatment method for slowing gully
erosion, and belongs to the technical field of water and
soil conservation. The method comprises four parts, namely gully selection, gully head treatment, gully bottom treatment and gully head wall treatment. In the gully, the slope of the left gully wall or the gully wall is less than or equal to 45 degrees and the height of the gully head wall is less than or equal to 5 meters;
jatropha curcas and dodonaea
viscose are planted above the gully head to form an
inverted U-shaped buffer
plant hedge belt above the gully head; timber piles are embedded into the
plant hedge belt crookedly; the width of an
inverted U-shaped opening is equal to that of the gully head or the width is 1 to 1.5 meters; the top of the
inverted U-shaped curve is 3 to 5 meters away from the gully head; leucaena glauca are planted on the gully bottom to form a U-shaped buffer
plant hedge belt on the gully bottom; the bottom of the U-shaped curve is 3 to 5 meters away from the gully head; lianas are planted and the
timer piles are embedded into the soil between the buffer plant hedge belts above the gully head and the gully bottom; and the two ends of iron wires are respectively fixed to the timber piles at the gully bottom and above the gully head and are attached to the ground surface. In the method, key points of slowing the gully
erosion are grasped; and the treatment configuration mode has high comprehensiveness, scientificity and reasonability.
