- Abstract
In arid regions like the deserts of Iran, where water scarcity and high evaporation rates pose significant challenges to vegetation establishment and irrigation, adopting innovative and environmentally friendly approaches is imperative for sustainable development. This study focuses on the application of deep subsurface irrigation using PVC pipes as a potential solution to mitigate these challenges. The experimental setup involved excavating a pit with a depth and diameter of 50 cm, where two PVC pipes were strategically placed on either side of the pit with a 20 cm spacing. The pipes were then filled with soil, and the study examined the wetting patterns in eight distinct treatments. Parameters such as the location of water exit holes, pipe diameter, the number of holes in the upper and lower sections, and hole diameter were systematically varied. The findings revealed that PVC pipes with a diameter of 12.5 cm and a height of 55 cm, featuring five double rows of 6 mm holes in the upper half spaced 3 cm apart, along with two holes in the lower half spaced 10 cm apart, yielded the most effective wetting pattern. This outcome holds crucial implications for water use efficiency, emphasizing the importance of achieving optimal wetting depths around plant roots. The depth of the wetting pattern is a key determinant for water resource management and encourages deep root development in plants. As a practical recommendation for irrigating seedlings in dry and desert areas, employing the specified treatment methodology is highly advisable, promising enhanced water utilization efficiency and sustainable plant growth.
