Abstract

The invention discloses a method for planting calliopsis on a side slope. The method comprises the following steps: preparing slope surface; backfilling nutrient soil on the slope surface, and laying non-woven fabrics or coarse sand on the nutrient soil; pouring ecological concrete and covering a plastic thin film for maintenance, wherein the ecological concrete is prepared from gravels, cement, micro silicon dioxide powder or fly ash, a water reducing agent and water according to a weight proportion by uniform mixing under stirring; sowing calliopsis seeds and carrying out watering for maintenance, wherein the calliopsis seeds are pretreated through the following steps before sowing: adding starch and 6-benzyl aminopurine into an extract obtained by mixing rhubarb and traditional Chinese medicinal clove, then carrying out stirring so as to obtain an emulsion, and soaking the calliopsis seeds in the emulsion for use. The method provided by the invention enriches diversity of plants cultivated on the ecological concrete; meanwhile, the calliopsis seeds undergo soaking pretreatment in the emulsion of the extract containing rhubarb and traditional Chinese medicinal clove before sowing, so the disease-resisting ability and the survival rate of the calliopsis seeds are improved.

Description

technical field [0001] The invention relates to the field of ecological protection, and more specifically, the invention relates to a method for planting cosmos on a slope. Background technique [0002] With the rapid development of my country's social economy, urban construction, hydropower, transportation, mining and other engineering constructions, due to engineering soil and rock filling and excavation, a large number of soil and rock exposed slopes have been formed, destroying existing vegetation and causing damage to the local ecological environment. There are two types of engineering slope protection: slope protection and support structure protection. Traditional slope protection measures such as masonry rubble, sprayed anchor protection, shotcrete, etc., and retaining structures such as retaining walls, anchor retaining walls, etc., these engineering measures may lead to the destruction of original vegetation, soil erosion, landslides and edge A series of ecological...
