Problems solved by technology

However, if this method is sprayed on the soil slope with a weeding machine, only reed-like grass will grow out, which is a single type, which is far from the surrounding natural vegetation, which reduces the greening effect and cannot meet the requirements of the ecological highway.

Embodiment 1

[0024]The K44+510-K44+700 slope of Yunwu Expressway was originally designed as a first-level experimental slope, which is a fully weathered siltstone slope with a thin soil layer and a slope ratio of 1:1. Clean and level the slope surface, remove pumice and floating roots on the slope surface, excavate wedge-shaped trenches on the slope surface, and use arch-shaped skeletons to reinforce the slope. The green protection of the slope surface uses three-dimensional net hydraulic spraying and planting grass, and the construction was carried out in early April 2007. . The type and amount of plant seeds sprayed on the slope are: Bermudagrass 2g / m 2 +Dal 8g / m 2 + Willow 10g / m 2 +Wild Lily 10g / m 2 + Masson pine 5g / m 2 + Leucaena 10g / m 2 , covered with non-woven fabric, sprayed with water and pre-cured.

[0025] In April, 2008, when the slope was covered by the herbaceous layer, the drilled hole (drill pipe) was used on the slope to Digging holes, the hole direction of the hole...

Embodiment 2

[0030] The K49+680~K49+900 slope of Yunwu Expressway was originally designed as a grade 4 experimental slope, but after excavation it is fully weathered siltstone, the soil layer of the grade 2 and grade 3 slopes is thin, and the slope ratio is 1:1. First clean and level the slope surface, remove pumice and floating roots on the slope surface, excavate wedge-shaped trenches on the slope, and use arch-shaped skeletons to reinforce the slope. construction. The type and amount of plant seeds sprayed on the slope are: Bermudagrass 2g / m 2 +Dal 8g / m 2 + Willow 10g / m 2 +Wild Lily 10g / m 2 + Masson pine 5g / m 2 + Leucaena 10g / m 2 , covered with non-woven fabric, sprayed with water and pre-cured.

[0031] In May of that year, when the slope was covered by the herbaceous layer, the drill (drill pipe) was used to drill the slope on the slope. Dig holes, the direction of the holes is perpendicular to the slope, the distance between the holes is 35-40cm, the hole depth is 10cm, and t...

Embodiment 3

[0036] The slope of LK52+810-LK52+900 of Yunwu Expressway was originally designed as a secondary experimental slope, and the primary slope is a fully weathered siltstone slope with a thin soil layer and a slope ratio of 1:1.5. First, the slope surface was cleaned and leveled, pumice and floating roots were removed, wedge-shaped trenches were excavated, and arched skeletons were used to reinforce the slope. The green protection of the slope surface was planted with three-dimensional net hydraulic spraying and grassing. The construction was carried out in early April 2007. The type and amount of plant seeds sprayed on the slope are: Bermudagrass 2g / m 2 +Dal 8g / m 2 + Willow 10g / m 2 + Wild Lily 10g / m 2 + Masson pine 5g / m 2 + Saltwood 10g / m 2 , covered with non-woven fabric, sprayed with water and pre-cured.

Abstract

The invention discloses a method for afforesting a completely-weathered aleurolite side slope by utilizing native plants. The method comprises: according to the characteristics of thinner soil layer and high and steep slope of the completely-weathered aleurolite, spraying and planting plant seeds by a hung three-dimensional net hydraulic soil replacement spraying and planting method; digging a hole on the side slope by combining with a side slope hole digging and fixing process; building a favourable environment for the plants to grow in the hole; planting the native plants (masson pines and Chinese cherries) into the hole; watering and applying fertilizer to cause the native plants to normally grow; planting native herb, native bush and native arbour on the side slope and around the side slope and a catchwater; after normal maintenance, afforesting the completely-weathered aleurolite side slope. The material adopted by the invention has no pollution. The method is characterized by biological environmental friendliness and improved afforestation survival rate; and in addition, the method does not affect environment, and belongs to energy-saving and clean production. The adopted native plants are subjected to side slope afforestation and are harmonious with surrounding environment, thus obtaining the result of efficiently combining the effects on afforestation, beautification, original ecology and environmental friendliness.

Description

Technical field: [0001] The invention belongs to the field of ecological and environmental protection science and technology, and in particular relates to a method for greening fully weathered siltstone slopes by using native plants. Background technique: [0002] Slope greening is the focus and difficulty of expressway greening. At present, expressway greening generally follows the principles of urban landscaping. We don’t know the ecological environment, vegetation conditions, and plant species along the highway. We mainly use exotic plants, and there are monotonous and resistant tree species. Poor performance and high maintenance and management costs. After excavation, the siltstone slope has a thinner soil layer and a high and steep slope. After greening the slope, with the growth of time, heavy rains in spring and summer, drought in autumn and winter, soil nutrients are gradually consumed and lost, and soil fertility It continues to decrease and poses a threat to plant...
