Greening planting technology for expressway in arid area of desert

Abstract

The invention belongs to a highway greening cultivation technology and in particular to a greening planting technology for an expressway in the arid area of desert. The technology is characterized by comprising the following steps: selecting corresponding arbor, shrub and grass according to the local topography, landform, climate characteristics, vegetation condition and common nursery stock varieties, and performing planting time selection, planting preparation, planting of the arbor, shrub and grass, vegetation maintenance, daily nursing and the like, wherein the arbor is selected from one or several of poplar, Saliz matsudana or pinus sylvestris; the shrub is selected from two or more of Amorpha fruticosa, Sabina vulgaris, caragana microphylla and hedysarum scoparium; and the grass is selected from one or several of medicago sativa, Astragalus adsurgens and Artemisia songarica Schrenk. According to the invention, the time from nursery stock planting to large-scale greening is basically consistent with the time from highway construction to operation, and the construction period is relatively reasonable; the selected nursery stock is common nursery stock which has sufficient supply source, is drought-resistant, easily survives and grows quickly; and the purchase cost and maintenance cost are low.

Description

technical field [0001] The invention belongs to highway greening cultivation technology, in particular to a highway greening cultivation technology in desert arid area. [0002] Background technique [0003] In desert areas, the climate is dry, the rainfall is scarce, the evaporation is large, the surface is prone to leakage, and the wind is strong, which makes desert vegetation scarce and difficult to survive. [0004] With the implementation of my country's western development strategy, the transportation industry in the western region has been vigorously developed. In the desert and arid areas that account for about 60% of my country's land area, high-grade roads have gradually increased. While each high-grade highway has become the lifeline of the economy, its construction has also caused damage to the special environment of the desert and arid area. The roads and shelter forests in the arid desert area divide the desert into two parts and have a huge impact on the soi...

AI Technical Summary

Problems solved by technology

In addition, the construction of the road requires excavation, filling and other processes, which will damage the integrity of the arid desert area. Human disturbance will change the composition of sand particles, the direction and speed of sand dune migration, and its own shape. Phenomenon of accumulation and loss of downwind

[0005] Therefore, if vegetation restoration is not carried out, mobile sand dunes will form in the bare areas along the line, which will affect driving safety on the one hand and further damage the surrounding vegetation on the other hand.
