Problems solved by technology

[0003] Due to the construction of the railway, it will inevitably have an adverse impact on the original fragile ecology. A large amount of spoil and slag generated during the construction will disturb the original fragile ecosystem such as surface water, soil, and plant species. Natural restoration is slow under these conditions, which will cause soil erosion, vegetation destruction, and desertification to develop radially, leading to intensified desertification in the area around the railway, resulting in sand accumulation on the railway roadbed and track, thus threatening the safety of railway operation
[0004] In the past, there were various problems in the greening design of railway slopes, such as single planting method, difficult plant growth, and general greening effect.

Embodiment Construction

[0028] The present invention will be described in detail below in combination with specific embodiments.

[0029] The invention relates to a method for planting shrubs on a railway slope in a desertification area. A skeleton and hollow bricks in the window holes of the skeleton are applied on the slope, and holes are dug in the hollow bricks to plant aquamarine and caragana.

[0030] Described method specifically comprises the following steps:

[0031] Step 1: Clean up the original covering soil in the skeleton and hollow bricks, and replace the planting soil;

[0032] Step 2: Digging holes in the hollow bricks, using manual methods;

[0033] Step 3: Plant the quinoa and caragana in the pit, the planting time is from April to May, and the mixed planting method is adopted, and the product is planted;

[0034] Step 4: Make a ring-shaped cofferdam around the pit for later maintenance and watering.

[0035] In step 1, the planting soil is replaced by 20cm, the organic matter co...

Abstract

The invention relates to a shrub mixed planting method for a railway slope in a desertification region. A framework and hollow bricks in window holes of the framework are constructed on the slope, andholes are dug in the hollow bricks for mixed planting of atriplex canescens and caragana microphylla. According to the method, shrubs such as the atriplex canescens and the caragana microphylla suitable for growing in the desertification region are selected and planted on the railway slope in the desertification region in a mixed manner in a certain mode, and a slope greening system is formed byreplacing and filling of high-quality planting soil, the drought-enduring and saline-alkaline-enduring shrubs, appropriate intercepting water measures and initial maintenance, so that the greening effect of the railway slope in the desertification region is ensured. The method has the advantages of being good in greening effect, high in soil conservation capacity, short in maintenance time, capable of saving water and low in cost, and is suitable for slope and terrace greening of railways, highways and the like in the desertification region.

Description

technical field [0001] The invention relates to the technical field of railway slope greening in desert areas, in particular to a method for mixed planting shrubs on railway slopes in desertified areas. Background technique [0002] In Northwest China, many railways pass through mainly desert and semi-desert areas, with barren vegetation, mostly fixed and semi-fixed sandy land (hills), with relatively small annual average rainfall and large annual average evaporation. The vegetation recovery layer in many areas is basically loess, silt, gravel, etc. with poor water supply conditions and poor nutrition, and even the bedrock is exposed in some sections, and the plant growth conditions are poor. [0003] Due to the construction of the railway, it will inevitably have an adverse impact on the original fragile ecology. A large amount of spoil and slag generated during the construction will disturb the original fragile ecosystem such as surface water, soil, and plant species. Nat...
