Problems solved by technology

Planting aquatic plants directly on the river bank is not resistant to rain erosion, and the function of water and soil conservation is not ideal; although the ecological bag slope protection technology solves the problem of vegetation planting to a certain extent, and has a better function of water and soil conservation, it is also not resistant to rain erosion as time goes by , its functions of water and soil conservation and water purification are also gradually lost; although the gabion construction of ecological river bank belts and artificial hardened bank revetments can fix the soil, they will directly destroy the basis for the survival of river bank vegetation, and the vegetation ecosystem will be destroyed and degraded.

Abstract

The invention discloses a method for planting thalia dealbata on a side slope. The method comprises the following steps: 1) preparing the slope surface: a layer of planting nutrient soil with thickness being 20-30 cm and a layer of gravelly soil with thickness being 5-10 cm are laid on the slope surface from bottom to top sequentially; 2) building ecological concrete: the ecological concrete is poured on the slope surface and is prepared through the following step: gravel, cement, silicon dioxide micro powder or fly ash, a water reducing agent and water are mixed and stirred in parts by weight; 3) planting the thalia dealbata; 4) performing conservation: performing watering 3-7 times each day after sowing, removing non-woven fabric after germination, and applying fertilizer once every 7 days. According to the method, a perennial aquatic plant, namely, the thalia dealbata is adopted as a planting variety and has developed roots, as well as high tillering capacity, growth rate and ornamental value, so that soil on the side slope can be effectively fixed, the ecological environment can be effectively improved, and the environment can also be well beautified.

Description

technical field [0001] The invention relates to a method for planting Zaolihua. More specifically, the present invention relates to a method for planting Zaolihua on a slope. Background technique [0002] With the acceleration of urban construction, some landscape ecological problems have appeared in the revetment of urban rivers, such as the destruction of original vegetation and soil erosion. In order to solve the above problems, the measures taken by traditional engineering measures include directly planting aquatic plants in the riparian zone, using ecological bag technology to protect the slope and planting plants, using gabions to build an ecological riparian zone, and artificially hardened bank revetment. Planting aquatic plants directly on the river bank is not resistant to rain erosion, and the function of water and soil conservation is not ideal; although the ecological bag slope protection technology solves the problem of vegetation planting to a certain extent, ...
