Problems solved by technology

Although the slope vegetation thus established has a good effect in the early stage of slope protection, there are generally problems such as single landscape, limited green period, and poor sustainability. The uniform lawn along the slope is extremely inconsistent with the surrounding natural environment, especially in autumn. In winter, the slope grass begins to wither and turn yellow, and the landscape along the road is completely withered, which is contrary to the original intention of establishing sustainable development

Embodiment 1

[0011] Evergreen vegetation was planted on a soil slope of the Southern Expressway, and it was implemented by hydraulic spraying. Construction process: ①Repair the slope to be greened, remove the gravel, etc., and repair the slope; ②Prepare the seed spraying liquid, the formula is: 55 grams of grass-irrigated plant seeds per square meter of slope (including 15 grams of Bermuda , ryegrass 10 grams, edamame 20, pig dung bean 10 grams), pulp 100 grams, binder (polyvinyl alcohol) 5 grams, water retaining agent (polyvinylamide) 5 grams, compound fertilizer (15-15 -15) 50 grams, 4 liters of water; ③Spray the prepared seed spray liquid evenly onto the slope with a hydraulic sprayer, and cover it with non-woven fabric;

[0012] Implementation effect: 1 month after spraying, the vegetation coverage reaches 80%, and 3 months later, the vegetation coverage reaches more than 90%. In the winter of that year, when the herbaceous plants such as Bermuda and ryegrass gradually withered and tu...

Embodiment 2

[0014] Evergreen vegetation was planted on a rocky slope of the Southern Expressway, and the method of spraying mixed grass with anchor rods and hanging nets was adopted. The construction process: ① Clean up and level the slope surface, remove pumice on the slope surface, fill the recesses, and chisel the convex parts , try to level the slope; ②Anchor rod hanging net, set up 1 anchor rod (φ16-18 rebar, 45-100cm in length) per 1.3 square meters, use pneumatic drill to drill holes (aperture 25mm), and the anchor rods are exposed for about 10cm, and fix the anchor rod with cement slurry; then hang the net, using ordinary wire mesh (φ18 wire) with an aperture of 50mm×50mm, the overlapping width between the mesh is not less than 5cm, and tie it with φ18 wire after tension to form a slope that can be planted. surface foundation; ③preparation of substrate mixture, the formula is: per cubic meter of clay mixed with chicken manure 8kg, compound fertilizer (15-15-15) 4kg, supplementary p...

Embodiment 3

[0017] The evergreen vegetation was planted on a soil slope of the Southern Expressway, and the hydraulic spraying method was adopted. Among them, the formula of seed spraying liquid: 45 grams of grass shrub plant seeds per square meter of slope (including 15 grams of Bermuda, 10 grams of edamame, 10 grams of pig's dung bean, 10 grams of succulent indigo), 150 grams of pulp, adhesive (polyvinyl alcohol) 5 grams, water retaining agent (polyvinylamide) 5 grams, compound fertilizer (15-15-15) 60 grams, water 4 liters.

[0018] Implementation effect: germinate 3 days after sowing, the germination rate is 90% 7-10 days after sowing, and the vegetation coverage rate of the slope reaches more than 85% after 3 months, and the slope is evergreen.

Abstract

A method for planting the evergreen vegetation on the slope of expressway in the south includes such steps as, choosing the grass seeds and bush seeds, mixing the grass seeds with bush seeds in ratio of 1:(1.2-2), preparing the spray sowing liquid of said seed mixture, and spraying it onto the slope of expressway.

Description

technical field [0001] The invention relates to a greening technology for expressway side slopes. Background technique [0002] Expressway slope greening technology is of great significance to prevent soil erosion, stabilize roadbed, improve road landscape, and ensure driving safety. According to the different plants used, slope greening can be divided into herbaceous greening, vine greening, grass-shrub mixed greening, grass-plant mixed greening, etc. Because people mostly focus on short-term greening benefits, the current popular practice in slope greening engineering circles is to use herbaceous plants for greening, and mainly to introduce foreign grass species, so that the slope can quickly achieve the purpose of restoring vegetation. Although the slope vegetation thus established has a good effect in the early stage of slope protection, there are generally problems such as single landscape, limited green period, and poor sustainability. The uniform lawn along the slope...
