Research progress of subsurface drip irrigation development and its application

Water scarcity is an important factor affecting the sustainable development of agriculture. Efficient irrigation techniques not only improve water use but also increase crop yields. Drip irrigation with high irrigation control can provide a better growth environment for crops, and its effect of water-saving and yield-increasing has been widely accepted. This paper briefly introduces surface drip irrigation technology and its existing problems, and further describes the development and superiority of subsurface drip irrigation technology. Finally, the defects of conventional subsurface drip irrigation technology are summarized, and a novel subsurface drip irrigation technology-sand tube irrigation (STI) is expounded. At the same time, the technology has been proved by some scholars, which is expected to provide new perspective and strong support for forests and fruit cultivation, ecological environment protection and economic growth in arid areas.
