Problems solved by technology

At present, some plants are used for the greening of end-wall-type tunnel openings, such as creeper, but creeper is a perennial deciduous vine, and the leaves will wither and fall in winter, so that the wall of the end-wall-type hole will be exposed, and the brown roots will also be exposed. disorganized
Therefore, the climbing plants currently used are not the most ideal three-dimensional greening plants at the entrance of the expressway end wall type tunnel.

Embodiment 1

[0017] Greening at the entrance of Shitijing end-wall tunnel of Guangwu Expressway from the estuary to the platform section:

[0018] (1) Prepare the seedbed in advance, level the seedbed, with a strip distance of 20cm, a width of 8cm, and a ditch depth of 4cm;

[0019] (2) Soak the harvested Mucuna birdwoodiana seeds in 80°C water for 6 hours, then replace them with normal temperature water (20-25°C), and change the water every 6 hours to avoid The water stinks and soaks for 72 hours to soften the seed coat to promote seed germination. When the seeds swell, they are taken out for sowing;

[0020] (3) Drill sowing or on-demand sowing: On the seedbed, sow 75-100g per square meter, cover with soil about 3cm after sowing, cover with straw, keep watering, and make the soil moist;

[0021] (4) About 20 days after sowing, the seeds begin to germinate. When the seedlings are 6-8 cm high, they are removed and transferred into a nutrition cup. , cultivated under a shading net with a ...

Abstract

The invention provides a three-dimensional greening method for end wall tunnel portals on super highways, which comprises: soaking seeds of Mucuna birdwoodiana in water till expansion, owing on a seedling bed, covering soil after sowing, covering straw, and spraying water for maintenance; transplanting in nutritional cups when the seedlings are 6 to 8 centimeters high, placing the nutritional cups under a shading net, and spraying water for maintenance; and in rainy season, transplanting cultivated bagged seedlings on two sides of the end wall tunnel portals on the super highways, loosening soil, watering for maintenance, and mounting a layer of met on the wall body of the end wall tunnel portals on the super highways, so that the Mucuna birdwoodiana can grow on the net. In the invention,the Mucuna birdwoodiana grow very fast and can cover 10-meter end wall tunnel portals on the super highways within two years; therefore, the greening successful rate is high, the operation is convenient, the promotion and use are easy, the greening effect is desirable, the greening ecological and landscape effects can be achieved quickly, noises and flying dust can be absorbed, special maintenance is not required, and the method can be widely used for greening the end wall tunnel portals on the super highways.

Description

Technical field: [0001] The invention relates to a method for greening the entrance of an expressway end-wall tunnel, in particular to a method for using Mucuna birdwoodiana Tutch. as a greening plant to green the entrance of an expressway end-wall tunnel. Background technique: [0002] With the acceleration of expressway construction in our country, when the expressway passes through mountainous areas, in order to reduce the large excavation of the mountain and protect the ecology along the line, tunnels are often used to pass through. The tunnel entrance mainly adopts the end wall type, cut bamboo type and other forms. When adopting end-wall tunnel openings, in order to weaken the adverse effects of large areas of hard surfaces on drivers, sometimes a hierarchical design is adopted, and the use of three-dimensional greening is an effective way to reduce the visual impact of drivers. As a form of three-dimensional greening, end-wall tunnel opening greening can reduce the a...
