| Abstract: |
| This study systematically reviewed the application progress of subsurface drip irrigation (SDI) technology and the technical parameters of the SDI system. It elucidated the transport characteristics of soil moisture, nutrients, and salt in orchards under SDI conditions and summarized the effects of SDI on fruit tree growth and the efficiency of water and fertilizer use.The results showed that the optimization of technical parameters such as buried depth of capillary, buried spacing and irrigation uniformity was enough to significantly improve the economic benefits of fruit trees. SDI had a significant impact on the distribution and transport pattern of soil moisture and solutes in the root zone of fruit trees, the downward transport distance of the wetting front was greater than the upward distance of the transport distance, and the spatial and temporal distributions of nutrients and salts were mainly affected by the distribution of soil moisture. SDI, through the provision of a fine amount of irrigation and nutrition supply, improved the efficiency of water and fertilizer usage, reduced the risk of environmental pollution in the orchard, promoted the healthy growth of fruit trees and the development of fruit quality, and enhanced the resilience of fruit trees and their adaptability to the ecological environment. In the future, we should continue to enhance the application of SDI technology in fruit trees, investigate its water\|saving and yield\|boosting mechanisms using empirical models, crop models, or remote sensing technology, and develop irrigation strategies tailored to different tree species, climatic conditions, and soil types to expand its applicability. |
