Railway along-line soil moisture conservation and weed prevention ecological micro rainwater collection system

Abstract

The invention discloses a railway along-line soil moisture conservation and weed prevention ecological micro rainwater collection system. The system comprises an artificial soil and stone V-shaped ridge built at the edge of a railway, wherein the low-lying area of the artificial soil and stone V-shaped ridge is a water collection area, a water collection pit is dug downwards in the water collection area, water-retaining films are laid on the upper surface of the artificial soil and stone V-shaped ridge and the upper surface of the water collection area, mound ridges are piled at the lower part of the artificial soil and stone V-shaped ridge at intervals; a natural sodium bentonite soil moisture conservation and weed prevention ecological cushion is tightly laid on the periphery of the inner wall of the water collection pit, a fine soil layer is laid at the bottom of the water collection pit, an underwater seepage debris stone cushion layer bundled in advance is arranged on the periphery of the root of the drought-resistant tree species, and a sand soil layer is buried in the root of the drought-resistant tree species; and a sheet-shaped and egg-shaped broken stone cushion layer is arranged on a plant straw cushion layer. According to the system, rainfall is fully collected and utilized, growth of weeds is prevented, herbicide is reduced, the effects of preserving soil moisture, storing water, increasing temperature and preventing weeds are achieved, the survival rate of sandy soil greening vegetation is increased, cost is low, and pollution to soil is avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural moisture conservation, and in particular relates to an ecological micro rain collection system for moisture conservation and weed prevention along railway lines. Background technique [0002] Water is the most basic environmental factor in the process of plant growth and development, and occupies an irreplaceable position in agriculture and forestry and fruit production. [0003] The Hami region of Xinjiang has a typical temperate continental arid climate, dry and less rainy, with many sunny days, an annual average temperature of 9.8 degrees, an annual precipitation of 33.8 mm, an annual evaporation of 3300 mm, an annual average sunshine of 3358 hours, and a frost-free period of 182 days. Spring is windy, changing temperatures and temperatures, summer is hot with strong evaporation, autumn is sunny and cools down quickly, and winter is cold with a stable lower air layer. The extreme maximum ...

Problems solved by technology

In addition, the areas where we restore green vegetation are all in wild mountainous areas. It is more labor-intensive and time-consuming to use sprinkler irrigation technology and water replenishment after vegetation planting, and we cannot guarantee the 100% survival rate of plants.
