Slope greening method for southwest region

Abstract

The invention discloses a slope greening method for the southwest region. The method comprises the following steps that soil replacement is conducted on slopes; native plant seeds of the southwest region and introduced plant seeds or naturalized plant seeds which are suitable for growing in the southwest region are sowed in a spraying mode on the slopes, wherein the native plant seeds comprise the hypericum patulum seeds and pyracantha fortuneana seeds, hypericum patulum is a semi-evergreen shrub and has the advantages that the insect pest injury resistance and the disease resistance are high, meanwhile, the hypericum patulum grows in a branching mode, the plant height is moderate, the emergence rate of the seeds is high, the flowering stage is long, the growth speed is high, and the hypericum patulum can bloom after one year the hypericum patulum seeds are sowed in a spraying mode; pyracantha fortuneana is an evergreen shrub and has the advantages of being resistant to drought and barren, resistant to defoliation, dense in branch and leaf and developed in root system, flowers are blooming in spring, fruits are countless in autumn, and the pyracantha fortuneana is a good tree species for landscaping and conservation of water and soil. The method is high in operability, simple in maintenance, quick in green recovery, long in flower viewing stage, resistant to water and soil loss, high in slope protection ability of the root system, good in landscape effect, good in phytocoenosium stability and capable of improving the landscapes on the road side slopes in winter.

Description

technical field [0001] The invention relates to the technical field of greening, in particular to a slope greening method in Southwest China. Background technique [0002] In the construction of roads, mines, hydropower and other projects, a large amount of excavation and filling is often required, forming a large number of exposed engineering wounds, which has caused a large number of ecological problems to the surrounding environment. Most of the basic engineering construction is a kind of engineering construction project characterized by destroying the surface ecology. The original vegetation cover is usually destroyed, resulting in the formation of a large number of secondary bare land such as cutting slopes, roadbed slopes, open-pit mine slopes, stone borrowing pits, and soil borrowing pits. Such problems have become a source of soil erosion, exacerbating the degradation of ecosystems. Under the influence of the theory of restoration ecology, with the help of the ecol...

AI Technical Summary

Problems solved by technology

[0004] At present, the energy of ecological restoration of engineering wounds is mainly focused on slope geotechnical protection and greening construction technology. Shotcrete, rigid skeleton (diamond, square, arch, herringbone frame), retaining wall, etc.; slope greening process includes guest soil spraying, hanging net guest soil spraying (single-layer net or double-layer net + support Board), ecological bag + hanging net guest soil spraying (single-layer net), platform planting, green net climbing vines, etc., insufficient attention has been paid to the goal of building artificial vegetation communities on slopes, resulting in unsatisfactory ecological restoration effects, such as rich species Low density, monotonous landscape, poor vegetation stability, etc., especially the application of evergreen and colorful plants on slopes is less, resulting in gray tone of winter landscape as a whole
