Abstract

The invention relates to a water retention-impermeable and breathable system for ecological planting. The water retention-impermeable and breathable system for ecological planting consists of a waterretention planting soil layer (1), a common planting soil layer (2) and an impermeable and breathable bottom layer (3) from top to bottom, wherein the impermeable and breathable bottom layer comprisesan upper protective layer (301), an impermeable and breathable layer (302) and a lower protective layer (303) from top to bottom. Compared with the prior art, the water retention-impermeable and breathable system for ecological planting solves the problems of easiness in water leakage, high evaporation and the like in an ecological planting process of an arid area, has the characteristics of water leakage prevention, steam suppression, water retention, ventilation and the like, remarkably improves the utilization rate of soil moisture while maintaining the respiration function of soil, and has a very wide application prospect.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a water retention-anti-permeation gas system for ecological planting. Background technique [0002] Desertification is not only a resource and environmental problem, but also an economic and social problem that cannot be ignored. An effective way to control desertification is to increase vegetation coverage to achieve the purpose of water conservation and water and soil conservation. However, the difficulties in vegetation construction in sandy and arid areas are: lack of water resources, irrigation and water diversion, and water delivery; high leakage and high evaporation of the soil itself in sandy and dry areas lead to low effective utilization of water resources and low plant survival rate. lower. Therefore, how to efficiently prevent soil moisture from infiltrating, slow down soil moisture evaporation, and improve its ability to retain and store water has become th...
