Method for planting canna on slope

Abstract

The invention discloses a method for planting canna on a slope. The method comprises the steps of preparing the slope; sequentially laying a nutrition soil layer and a gravel soil layer on the slope from bottom to top; pouring ecological concrete and covering the slope with a plastic film for protection, wherein the ecological concrete is obtained by mixing and stirring gravels, cement, silicon dioxide micro powder or coal ash, a water reducing agent and water to be uniform according to a certain weight part ratio; sowing canna seeds, wherein the canna seeds are pretreated before sowing, first filter liquid extracted from semen cassia and second filter liquid extracted from cortex magnoliae officinalis are mixed to obtain mixed liquid, and the canna seeds are soaked in the mixed liquid; watering and protecting are carried out after sowing. By means of the method, variety diversity of cultivated plants on the ecological concrete is enriched, and the canna is high in tillering capacity, grows quickly and has high ornamental value; the canna planted on the slope can effectively fix slope soil, improve the ecological environment and can beautify the environment well.

Description

technical field [0001] The invention relates to the field of ecological protection. More specifically, the present invention relates to a method of growing cannas on slopes. 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, a...

AI Technical Summary

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.
