Problems solved by technology

[0002] The state of the subgrade slope is related to the stability of the subgrade, which in turn affects the use quality and passing capacity of the road surface. Because the road is completely in the natural environment, the subgrade slope is vulnerable to rain, snow, and running water, and vegetation can protect the slope, green the environment, Improve the road landscape effect, but if the selected grass species have poor drought resistance, shallow root system, and slow reproduction, it is often difficult to achieve the purpose of maintaining water and soil and maintaining roads

Embodiment Construction

[0011] To effectively apply purple fescue to soil and water conservation projects on roadside slopes, the key to success lies in the timely and correct planting of purple fescue. Conservation management, forming high-density above-ground hedges and underground high-strength biological walls and network structures, the implementation steps are as follows:

[0012] 1. Roadbed slope cleaning and leveling

[0013] Before planting, weeds, stones and other sundries on the slope should be cleaned, and the land should be 10-20 cm deep to change the soil structure, enhance water permeability, improve water storage, moisture conservation and drought resistance, which is conducive to the growth of red fescue.

[0014] 2. Sowing

[0015] Grass seed sowing adopts lawn spraying technology, and uses a special jet pump to spray evenly mixed grass seeds, fertilizers and health-care materials on the soil surface through pipelines and spray guns at a high enough pressure to form a soft and stab...

Abstract

The invention discloses a slope vegetation method of an expressway. The slope vegetation method includes: selecting a herbaceous plant of the grass family through a large amount of comparisons, wherein the herbaceous plant is developed in rooting system, strong in expandability, barren-resisting, extensive management resisting, rich in seed, strong in germinability, easy to update and capable of conserving water and fixing soil; and planting red fescue on a leveled slope according to a certain method. The slope vegetation method is simple, low in management cost and remarkable in effect, preserves the soil and water once for all and is worthy of popularization.

Description

technical field [0001] The invention belongs to the field of ecological water and soil conservation, in particular to a method for vegetation slope protection of expressways. Background technique [0002] The state of the subgrade slope is related to the stability of the subgrade, which in turn affects the use quality and passing capacity of the road surface. Because the road is completely in the natural environment, the subgrade slope is vulnerable to rain, snow, and running water, and vegetation can protect the slope, green the environment, Improve the road landscape effect, but if the selected grass species have poor drought resistance, shallow root system, and slow propagation, it is often difficult to achieve the purpose of maintaining water and soil and maintaining roads. Contents of the invention [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a method for vegetation slope protection of highways. The te...
