Summary: This study found that subsurface drip irrigation significantly reduced the cadmium content in roots, shoots, and fruits, increased yield, and improved root growth and activity in soil at a depth of 20-40 cm compared to other treatments, although the cadmium concentration in the rhizosphere was not significantly decreased. The microbial population and enzyme activities in the rhizosphere of subsurface drip irrigation and alternate-rows irrigation were basically higher than that of surface drip irrigation and conventional furrow irrigation.

Summary: A sensor-based drip irrigation system was developed and evaluated for tomato and watermelon productions under different mulch conditions in a two-year field experiment. Results showed that drip irrigation under black plastic mulch yielded the highest tomato production, while drip irrigation under clear plastic mulch led to the highest watermelon production.

Summary: This study aimed to investigate the effects of subsurface drainage spacing on soil salinity and groundwater level. The results showed that subsurface drainage reduced soil salinity and effectively controlled the groundwater table. Decreasing the drain spacing further enhanced these effects.

Summary: The study found that the soil microbial community near the SDI emitter is significantly affected, with changes in bacterial and fungal diversity and structure. Bacterial community in soil is more affected by SDI system, while fungal diversity is not influenced by emitter proximity, but is lower in fields with established SDI systems.

Summary: Improving crop production in heavy coastal silt saline soil through establishing an irrigation system with saline water has been a challenge. This study investigated the effect of irrigation water electrical conductivity (ECw) on soil salinity (ECe), sodium adsorption ratio (SAR), pH of the saturated paste (pH(s)), tomato yield, and irrigation water use efficiency (IWUE). The results showed that maintaining ECw below 4.7 dS m(-1) is crucial for high-yield tomato cultivation in heavy coastal silt saline lands.

Summary: This study analyzed relevant literature from the Web of Science Core Collection spanning from 2002 to 2022 to investigate the research hotspots and development trends of subsurface drip irrigation (SDI) over the past 20 years. The analysis revealed an overall upward trend in the annual publication volume, with the United States having the highest publication volume and China showing the fastest growing publication rate in recent years. The research topics have become increasingly diverse, with water conservation and yield increases being the primary research objectives of SDI.

Summary: This study focused on the impact of irrational water and fertilizer regimes in greenhouse vegetable fields on the environment and economic aspects. The results showed that traditional flood irrigation led to nitrogen surplus and high risk of loss, while using drip fertigation and reducing urea-N application could reduce nitrogen and greenhouse gas emissions, but negatively affect farmers' net return.

Summary: This study investigated the effects of drip irrigation under plastic film mulch on cotton rhizosphere microbiota and soil functionality. The results showed that drip irrigation under plastic film mulch increased bacterial diversity, lowered salinity, and increased soil moisture. However, it also resulted in reduced root biomass and soluble sugar content, leading to a decrease in certain bacterial taxa and an increase in others. Drip irrigation also decreased the richness of the core bacterial network module and suppressed soil nutrient cycling.

Summary: A finite element model was developed for the hydraulic design of subsurface drip irrigation subunits. The model discretized the governing differential equation for water flow in a multi-outlet pipeline using the Galerkin method and employed a virtual emitter concept for rapid convergence on an ordinary computer. Increasing the number of elements discretized in a pipe was found to improve the accuracy of the model.

Summary: An indoor subsurface irrigation experiment was conducted on aeolian sandy soil to investigate the wetting front movement distances under different irrigation flows. A dimensional analysis was performed on the experimental data and an empirical estimation model was proposed. The model's accuracy was evaluated with observed data and numerical simulation, indicating its potential in selecting the appropriate depth and spacing of subsurface laterals.

Summary: This study investigated the influence of irrigation water salinity and sodium-calcium molar concentration ratio on tomato cultivation. It found that higher salinity and lower sodium-calcium molar concentration ratio in irrigation water positively affected root water uptake and average fruit weight, while lower salinity and higher molar concentration ratio positively affected tomato yield and fruit quality.

Summary: This study calibrated and validated the AquaCrop model to predict cotton production under climate change in southern Xinjiang. The results showed that increasing irrigation mitigated the negative impact of temperature on cotton yield, while high temperatures reduced cotton yield under a low irrigation level. Optimal irrigation strategies can reduce warming-induced damage to crops.

Summary: Non-film drip irrigation cotton planting can effectively address film pollution in arid areas and promote sustainable agriculture, but research on appropriate irrigation regimes and soil hydrothermal microenvironment is lacking. Using IoT sensors, we conducted a study with three different irrigation treatments. Results showed that increasing irrigation amounts significantly increased soil water content in the 50-110 cm soil layer. The W6 treatment had the highest soil temperature and effective accumulated temperature, leading to higher reproductive organ allocation rates. However, as irrigation amounts increased, water use efficiency decreased.

Summary: This study investigated the influence of the exogenous application of salicylic acid alone or in combination with glycine betaine on the growth, yield quality, and water-use efficiency of onions under different deficit drip irrigation treatments. The results showed that onions could tolerate moderate water stress and the application of salicylic acid improved plant growth and yield.
