Water-saving planting device for road-region vegetation in arid area

Abstract

The invention discloses a water-saving planting device for road-region vegetation in an arid area. The device consists of an open vegetative container and a layered packing layer; the layered packing layer is formed by arranging a plant fiber layer, a water-retaining nutrient soil layer for seeding, a biodegradable plastic thin film with a plurality of air holes and a grass blanket layer in the open vegetative container from bottom to top in sequence. The device disclosed by the invention can lock moisture, prevent moisture evaporation or leakage, maintain the necessary moisture content required for road-region vegetation growth for a long time, improve the survival rate of the vegetation and reduce the irrigation cost.

Description

technical field [0001] The invention belongs to the technical field of road construction environmental protection, and in particular relates to a water-saving planting device for road area vegetation in arid areas. Background technique [0002] Most of the roads in Northwest my country pass through loess hilly and gully areas where beams and gullies intersect. The geological conditions of the sections of the road are complex, and the soil is mostly subsidence loess soil. Many sections are prone to landslides, debris flows and other soil erosion phenomena. The stability of the roadbed, people's travel and local economic construction have a negative impact. From the perspective of protecting the environment, improving the landscape and increasing stability, the greening and landscape of high-grade highways in Northwest China have been widely concerned and highly valued by the construction units. During the construction process, the relevant road greening and environmental prote...

Problems solved by technology

Although the investment is often large, the effect is not ideal. It is neither scientific nor economical, resulting in repeated investment of funds and increased tasks of the road maintenance management department in the later period. Frequent replacement of seedlings also bury safety hazards for traffic safety.

[0003] The traditional method of vegetation restoration in arid areas is to plant seedlings in the bare soil along the highway and irrigate with water trucks. The water use efficiency is low, the cost is high, and the survival rate of seedlings is low.
