Greening method for traffic zones of railway tracks

Abstract

The invention discloses a greening method for traffic zones of railway tracks, and aims at providing a greening method in which an environment suitable for the growth of plants is created at the traffic zones of the railway tracks without affecting safety running of trains, and which basically depends on natural precipitation and has low post-maintenance cost. The method comprises the following steps: laying a base nutritional substrate on a ballast surface of a railway subgrade surface, watering to cause the base nutritional substrate to be fully mixed with subgrade stones, and forming a basenutritive layer which is used as a base and a nutrient source for the plant growth; sowing coated seeds of low drought-resistant plants on the base nutritional substrate, and laying a surface nutritional substrate on the seeds as a surface nutritive layer for protecting the seeds and providing a nutrient source for plant growth; and maintaining according to conventional lawn maintenance management methods. The greening method reduces the construction difficulty, basically depends on natural precipitation, and has high survival rate of plants and low post-maintenance cost; can greatly improveambient environment of railways, and maintain the ecological balance.

Description

technical field [0001] The invention relates to the technical field of greening engineering, and more specifically relates to an engineering technology of railway greening by adding nutrient substrates and carrying out lawn maintenance in the subgrade environment of the railway track driving area. Background technique [0002] At present, environmental greening has become an important part of urban environmental construction, and railway slope greening has always been the focus of the industry. The application of greening on railway slopes has been very common, but the application of greening in the railway track driving area, especially in the middle of sleepers, has always been regarded as a restricted area, mainly restricted by site conditions and construction conditions, the construction is difficult and the quality is difficult to control , Plants are difficult to survive. The greening of the railway track driving area is of great significance for improving the environ...
