Problems solved by technology

[0003] Traditional slope restoration methods mainly repair the slope from plants or engineering structures. Planting plants on the slope can restore the slope vegetation landscape to a certain extent, but it cannot form a stable slope structure, and the slope soil is susceptible to damage. Rainwater erosion and loss; engineering structure treatment mainly adopts methods such as mortar (dry) masonry and spray anchor protection. Although these treatment methods can form a stable slope structure, they will destroy the original vegetation, and cannot form a vegetation landscape and restore the slope. vegetation ecosystem

Abstract

The invention discloses a method for planting acorus tatarinowii on a side slope. The method comprises the steps that the slope surface is cleared up; nutrient soil is backfilled on the slope surface and covered with a gravel soil layer with the thickness of 5-10 cm; ecological concrete is constructed, wherein gravel, cement, silicon dioxide micropowder recycled from a ferrosilicon smelting electric furnace, a water reducing agent and water taken as raw materials, mixed to be uniform according to a certain proportion, poured on the gravel soil layer, vibrated and leveled to form the ecological concrete with the thickness of 5-10 cm; acorus tatarinowii is planted, wherein plant division is performed on the acorus tatarinowii to obtain small acorus tatarinowii plants each of which has 6-7 tillers, cylinders with the diameter of 2-10 cm are vertically placed on the ecological concrete every other 25-30 cm, roots of the small acorus tatarinowii plants are inserted into the cylinders, an aqueous agar solution is poured into the cylinders, and after the aqueous agar solution is solidified, the cylinders are removed; curing is performed. According to the method, a stable slope protection structure can be formed, and the water and soil conservation function is achieved; meanwhile, a complete vegetation landscape can be formed, and the ecological environment is improved.

Description

technical field [0001] The invention relates to the technical field of ecological protection, more specifically, the invention relates to a method for planting calamus on a side slope. Background technique [0002] During the construction of highway construction, municipal engineering or garden projects, a large number of soil and rock exposed slopes are formed due to earth and rock filling and excavation. The exposed slopes not only affect the harmony of the landscape, but also easily cause slope rocks under the erosion of rainwater quality or soil loss, and even collapse accidents. In the past, simple engineering protection was usually used, such as mortar (dry) masonry and shotcrete anchor protection. These engineering measures have caused a series of ecological environment and engineering problems such as destruction of original vegetation, soil erosion, landslides, and slope instability. Therefore, it is necessary to use resources rationally in engineering construction...
