Efficient ecological restoration method for slope in South China

Abstract

The invention discloses an efficient ecological restoration method for a slope in South China. The efficient ecological restoration method comprises the following steps that the bare slope face is cleaned, a net is fixed to the slope face, and a planting matrix or covering soil is sprayed; thysanolaena maxima spikelets and caryopsises are selected; then white tephrosia seeds are selected and processed; bacteria-removed sawdust is soaked in water, thereby fully absorbing water, then the bacteria-removed sawdust is dredged out, the bacteria-removed sawdust, the thysanolaena maxima spikelets and caryopsises and bermuda grass seeds are mixed evenly, and standing is conducted; and the bacteria-removed sawdust and the bermuda grass seeds mixed with the thysanolaena maxima spikelets and caryopsises, the white tephrosia seeds, fertilizer and water are evenly mixed and stirred to be made into spray-seeding materials, the spray-seeding materials are sprayed through a spray-seeding machine or are sown manually onto mud of the slope face, the slope face is covered with nonwovens, and maintenance is conducted. The efficient ecological restoration method has the characteristics that vegetation of the slope can be obtained fast, ecological restoration is fast, water and soil loss can be prevented effectively, the vegetation succession process can be facilitated, and harmonious and sustainable development of road slope virescence and surroundings is achieved.

Description

technical field [0001] The invention relates to the field of slope environmental ecological restoration, in particular to a method for efficient ecological restoration of slopes in South China, which is widely applicable to South China regions such as Guangdong, Guangxi, southern Yunnan, and southern Fujian. Background technique [0002] In recent years, with the rapid development of the economy and society, the country has accelerated the pace of infrastructure construction, especially in the economically developed South China region, where the investment is large and the construction period is longer. In such a high-speed development and construction, the impact on the ecological environment is also increasing. Among them, the exposed slopes generated by the excavation of the mountain and the large-area exposed broken surfaces of abandoned quarries are especially common in the construction of expressways. . In southern China, where there is abundant rainfall, exposed slop...
