Abstract

The invention discloses a road side slope ecological restoration meshed backflow water-holding and water-saving method and application thereof. The method comprises the steps of: (1) ditching, to be specific, respectively digging multiple backflow ditches in the transverse direction of the side slope and digging multiple water guide ditches in the lengthways direction of the side slope according to scale and gradient of the side slope, wherein the backflow ditches and the water guide ditches are in a criss-cross state; (2) backfilling, to be specific, filling a mixed substrate which is composed of a high-humus material and a macromolecular water-holding water absorbent in the backflow ditches and the water guide ditches, and then adding planting soil; and (3) planting grass and shrub type plants on the planting soil. According to the road side slope ecological restoration meshed backflow water-holding and water-saving method, disclosed by the invention, the slope-to-terrace pattern is formed to a certain degree, loss of soil and water is prevented efficiently and high integral water-holding and water-supplying capability is obtained; and by adopting a meshed backflow water-holding technology, water storage function of the backflow ditches and water delivery function of the water guide ditches can be fully utilized, daily maintaining and water-spraying time is reduced efficiently, and water-saving effect is obvious.
