Slope vegetation recovery method adopting combination of creeping plants and positive pioneer plants

Abstract

The invention provides a slope vegetation recovery method adopting combination of creeping plants and positive pioneer plants. The method comprises the steps that the creeping plants rooted on nodes are planted through artificial holes; planting pipes are inserted between ground cover layers of the creeping plants according to a set distance, through holes are formed in the pipe walls of the lower portions of the planting pipes, and pioneer shrub plants are planted in the planting pipes. By the adoption of the technical scheme, the shrubs are planted in a tubular mode, the creeping ground cover plants are planted in holes, the ground cover plants with high coverage degree can be rapidly formed, slope surface upper layer vegetation can be flexibly constructed according to the slope surface environment characteristics, and therefore a slope surface three-dimensional plant community structure is constructed. The scouring force of rainwater can be reduced in a multi-layer mode, the slope runoff is controlled, slope vegetation is promoted to develop towards a three-dimensional community structure, and stable slope vegetation is formed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a slope vegetation recovery method using a combination of creeping plants and positive pioneer plants. Background technique [0002] Slope vegetation restoration technology is currently mainly through seed spraying technology, plant planting methods and blanket plant planting methods to form slope vegetation in a way of natural growth and natural succession. Among them, the seed spraying technology is a method of spraying seeds on the surface of the slope soil through a spraying machine, and covering them with non-woven fabrics and other maintenance measures. Most of the plants are gramineous plants such as bermudagrass, tall fescue, and ryegrass. And leguminous plants such as edamame, pig's dung bean, and silver acacia. These plants have the characteristics of large seed quantity, sufficient provenance, high germination rate, and rapid vegetation rec...

AI Technical Summary

Problems solved by technology

[0003] The above seed spraying techniques, plant planting methods and blanket plant planting methods all show natural growth and natural succession. The community structure is difficult to control, and there is often a phenomenon of vegetation degradation or formation of a single dominant population in the later period. Most of the selected plants are upright. Herbaceous plants and shrubs, and due to problems such as too large or too small planting or seed density, the final plant community structure is unstable, showing a single shrub layer or herb layer phenomenon, the "empty foot" phenomenon is very obvious, and the water and soil conservation effect is relatively poor. Poor, measures such as covering with non-woven fabrics are often required in the early stage to reduce slope runoff

Seed spraying technology is more often due to the quality of the seeds themselves, external natural environmental conditions, and maintenance techniques and other factors, the germination of plant seeds and plant growth are relatively unstable, and the vegetation coverage is difficult to control

The blanket planting method needs to consider the planting medium material and thickness of the blanket and the soil characteristics of the slope itself, and the plant growth is also mixed together, and there will also be problems of plant growth competition and uncontrollable community structure
