Summary: Water shortage and soil salinization are major constraints to sustainable agriculture in arid and semi-arid regions. This study investigates the impacts of long-term mulched drip irrigation with brackish groundwater on soil and groundwater environments. The results show that groundwater level decline reduces evaporation and groundwater recharge, while soil moisture content and salinity are strongly influenced by groundwater depth.

Summary: Hetao Irrigation District (HID) is a major region for maize and sunflower production in North China. Water resource shortages and soil salinization greatly limit crop production, but the use of plastic mulching and drip irrigation methods have been found to reduce water usage and increase crop yield. A study conducted in 2021 and 2022 showed that mulching and irrigation methods had significant effects on soil salt content, nitrogen distribution, and maize yield.

Summary: The shortage of freshwater resources is a challenge for agricultural production in the North China Plain. A field experiment was conducted to investigate the effects of different salinities of irrigation water on the yield and soil quality of mulched drip-irrigated cotton. The results showed that salinity of irrigation water had a significant impact on cotton yield and soil quality.

Summary: This study conducted a 4-year field experiment in coastal saline soil of North China to establish four ornamental tree species using saline water for drip irrigation, with a focus on controlling soil matric potential. The results showed that as salinity levels increased and matric potential thresholds decreased, the survival rates and growth performance of trees varied. The study demonstrated the potential for landscaping with saline water and discussed the implications for irrigation management sustainability.

Summary: Salt leaching has been widely used to increase crop production in saline-alkaline soils. However, the effects of leaching patterns on soil ion composition and cotton yield under mulched drip irrigation are poorly understood. This study investigated the impact of different leaching amounts and timings on soil ions and cotton yield. The results showed that increasing leaching amount significantly reduced soil ions and improved cotton yield. The optimal leaching pattern was determined as 225 mm leaching amount at seedling and budding stages.

Summary: This study investigated the actual effect of oxygenation irrigation in field planting through a field experiment. The results showed that mechanical oxygenation achieved saturated dissolved oxygen faster and had higher stability compared to venturi oxygenation. Chemical oxygenation was not limited by saturated dissolved oxygen but required more reaction time to reach a stable state. Increasing the dissolved oxygen concentration in irrigation water improved the soil oxygen condition of mulched drip irrigation.

Summary: The study found that under drip irrigation, controlling soil matric potential below -30 kPa is beneficial for increasing maize leaf area index, specific leaf area, biomass, and yield. For each 1dS/m increase in soil ECe, maize yield decreases by 6.8%. Therefore, in this study, salt stress rather than water stress was identified as the key factor leading to reduced crop yield.

Summary: This study investigates the improvement of subsurface pipe layout and long-term soil salinization control in arid and semi-arid agricultural areas. Field experiments and numerical model calculations were conducted to understand water and salt migration during soil amendment. The results show a positive correlation between salt concentration in surface pipe drainage and soil salt content, as well as pipe depth and a negative correlation with irrigation water amount and crop spacing. The findings provide insights for the optimal layout of subsurface pipes to develop strategies for desalination and salt control.

Summary: Drip irrigation under mulch is widely used in arid regions of northwest China, but it can lead to salt accumulation on bare soil surfaces. This study investigated the hydrothermal dynamics and salt distribution patterns under such conditions. Tank experiments and modeling using HYDRUS-2D were conducted, and the results showed that uneven distribution of water and heat led to salt accumulation on bare soil surfaces. Lower drip irrigation intensity and increased lateral migration of water improved desalination efficiency in the root zone.

Summary: Water deficiency and soil salinization have long been hindering sustainable agriculture globally. Optimizing soil moisture regulation is beneficial for improving the soil water and salinity conditions for crops, thus promoting plant production. A field experiment in southern Xinjiang revealed that as the drip irrigation belt got farther away, the soil moisture decreased and the soil salinity increased. It was also observed that soil moisture and salinity increased and then decreased with soil depth after irrigation, following an elliptical distribution. Therefore, it is recommended to maintain a soil moisture lower limit of 75% FC for cotton cultivation in southern Xinjiang.

Summary: A field experiment in China's Bohai Bay region evaluated the integrated use of saline water for saline soil reclamation. By cultivating landscape shrubs with varying water salinities and evolving irrigation schedules, significant improvements in soil salinity levels were achieved. However, plant survival and growth were impacted by increasing salinity levels, highlighting the importance of optimizing soil water and salinity conditions during the leaching process.

Summary: Saline water irrigation can help alleviate the shortage of freshwater resources in agriculture, but it may also lead to soil salinization and impact crop quality. The water-salt regulation (WSR) irrigation method can effectively avoid soil salinization and enhance the quality of tomatoes. The field experiment in the arid region of northwest China demonstrated that saline water irrigation can improve tomato quality while maintaining soil salinity balance. However, higher salinities of irrigation water resulted in decreased yield. It is important to maintain a balanced soil salinity level for sustainable production.
