“…Water-fertilizer integration technology originated in Israel in the 1960s, and drip irrigation equipment was introduced in China in the 1970s, and is now in the stage of vigorous promotion and application in China [10]. Drip irrigation realizes the coupled application of water and nitrogen into the soil at the root system [11], which not only improves the efficiency of water and nitrogen utilization and reduces the irrational use of resources [12], but also protects the environment and reduces N wetting [13] and C emissions [14].…”

Drip irrigation is a water-saving and fertilizer-saving application technology used in recent years, with which the frequency of drip irrigation nitrogen application has not yet been determined. In order to investigate the effects of different drip irrigation nitrogen application frequencies on the processing quality of medium-gluten wheat (Jimai22) and strong-gluten wheat (Jimai20 and Shiluan02-1), a two-year field experiment was carried out. Two frequencies of water and N application were set under the same conditions of total N application (210 kg·ha−1) and total irrigation (120 mm): DIF4, consisting of four equal applications of water and N (each of 30 kg·ha−1 of N application and 30 mm of irrigation) and DIF2, consisting of two equal applications of water and N (each of 60 kg·ha−1 of N application and 60 mm of irrigation). The results showed that IF4 significantly increased protein content by 2–8.6%, wet gluten content by 4.5–22.1%, and hardness value (p > 0.05), and PC2 was considered as a protein factor; the sedimentation value was highly significantly correlated with most of the parameters of the flour stretch (p < 0.01). DIF4 improved the stretching quality, and the flour quality of Jima22 was decreased, the flour quality of strong-gluten wheats Jimai20 and Shiluan02-1 was improved, and PC1 was considered to be the dough factor. In conclusion, although the frequency of nitrogen application by drip irrigation increased the protein factor and improved the tensile quality, the flour quality was not necessarily enhanced.

Seasonal drought and traditional water‐fertilizer management limit the increase in the grain yield of summer maize in Southwest China. Drip fertigation mode (HM) can effectively improve crop yields. However, research on drip fertigation has not been conducted in Southwest China. A 2‐year field experiment about HM was carried out with the traditional water‐fertilizer management mode (FM) as control. The plant densities were 5.25 × 104 plants ha−1 and 8.25 × 104 plants ha−1 in 2022 and 6.00 × 104 plants ha−1 and 9.00 × 104 plants ha−1 in 2023. The effects of HM on the aboveground biomass, leaf area index, yield, and resource utilization rate of summer maize were studied. Compared with the FM treatment, the HM treatment significantly increased the yield (25.18%), aboveground biomass (25.58%), leaf area index (34.87%), and leaf area duration (29.60%). HM optimized the canopy structure with an 11.05% improvement in light transmission at the top and a significant 61.32% increase in cumulative light radiation interception per unit area at the bottom of the canopy. The nitrogen partial factor productivity (NPFP), radiation utilization efficiency (RUE), heat utilization efficiency (HUE), and economic benefits of the HM treatment significantly increased by 39.58%, 49.45%, 25.92%, and 32.53%, respectively. In addition, dense planting increased the irrigation water use efficiency (IWUE) by 14.25%. In summary, drip irrigation combined with water and fertilizer can significantly improve maize grain yield, resource utilization efficiency, and economic benefits by increasing light interception in Southwest China. This study will lay a theoretical foundation for filling the relevant research gap in the region.

Water-saving irrigation techniques play a crucial role in addressing water scarcity challenges and promoting sustainable agriculture. However, the selection of appropriate water-saving irrigation methods remains a challenge in agricultural production. Additionally, the molecular regulatory mechanisms of crops under water-saving irrigation are not yet clear. This review summarizes the latest research developments in the application of different water-saving irrigation technologies to five important crops (rice, wheat, soybeans, maize, and cotton). It provides an overview of the impact of different irrigation techniques on crop yield, water use efficiency (WUE), physiology, growth, and environmental effects. Additionally, the review compares and contrasts the molecular regulatory mechanisms of crops under water-saving irrigation techniques with those under traditional drought stress, emphasizing the significance of combining irrigation technologies with genetic engineering for developing drought-resistant varieties and improving WUE. Furthermore, the integration of various technologies can stimulate new management strategies, optimize water resource utilization, and enhance sustainability, representing a major focus for future research. In conclusion, this review underscores the importance of water-saving irrigation technologies, especially when combined with genetic engineering, in addressing water resource scarcity, increasing crop yields, and promoting sustainable agriculture.
