Background At present, the traditional slope protection technology mainly comprises rigid protection measures such as slurry rubble slope protection, anchor spraying support, net hanging and concrete spraying. The technology can provide stronger slope stability in a short period, but the concrete or mortar coating layer blocks soil and moisture conditions required by vegetation growth, completely loses ecological functions, and the rigid structure is easy to crack and fall off on a steep broken rock slope due to foundation deformation, and has insufficient long-term stability. In recent years, ecological slope protection technology is gradually rising, such as soil spraying, vegetation concrete, vegetation bags and the like, and attempts are made to build vegetation growing environments on slopes.
