A micro-water circulation construction method and system based on day-night energy difference and application thereof in desert ecological restoration without continuous irrigation
By constructing a micro-water circulation system with diurnal energy difference, the problems of weak condensation and water collection capacity, serious secondary evaporation of condensate, poor stability of root zone microenvironment, and rapid decay of long-term water retention effect in plant cultivation in arid areas have been solved. This system enables water return and reuse under conditions without continuous external irrigation, thereby improving plant growth and ecological restoration efficiency.

AI Technical Summary
Existing ecological restoration and plant cultivation technologies in arid areas rely on external water supply, which cannot effectively utilize the potential water resources in the arid environment. This results in weak condensation and water collection capacity, severe secondary evaporation of condensate, poor stability of the root zone microenvironment, rapid decline in long-term water retention effect, and difficulty in continuous implementation on a large scale in remote areas without water sources.
A micro-water circulation system based on diurnal energy difference was constructed, including an anti-evaporation interface layer and a porous phase change-induced interface layer. By utilizing the periodic energy changes caused by diurnal temperature difference, soil moisture evaporation was blocked, and air moisture was condensed and flowed back to the plant root zone, forming a stable water return and reuse.
It effectively utilizes the diurnal energy difference and air moisture in the external environment to form a stable water return and reuse in the plant root zone, thereby improving plant survival rate and growth quality, reducing dependence on groundwater and external water resources, and has a wide range of applications, low construction costs, and is suitable for various arid, semi-arid and desert environments.
