Special Issue Information

Dear Colleagues,

With the growth in the global population and socioeconomic development, the demand for food is gradually increasing while the amount of water resources for irrigation is constantly decreasing, and the contradiction between the supply and the demand for water resources is thereby becoming increasingly prominent. Water-saving irrigation is an important way to resolve this contradiction. Water saving irrigation can not only reduce irrigation water consumption and improve crop yield and water use efficiency but also improve fertilizer use efficiency, reduce farmland pollution of the environment, and promote the safe and sustainable development of water resources and the environment.

Therefore, we are happy to announce the launch of this Sustainability Special Issue, “Sustainable Water-Saving Irrigation”. It focuses on the research trends and progress in terms of new technologies for water-saving irrigation the efficient utilization of water and fertilizer in water-saving irrigation and its impact on sustainable development of the environment.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • New technologies for water-saving irrigation
  • New theories of water-saving irrigation
  • Efficient utilization of water and fertilizer in water-saving irrigation
  • Response of crop growth process to water-saving irrigation and crop growth model
  • Effect of water-saving irrigation on farmland ecological environment
  • Intelligent irrigation theory and technology

We look forward to receiving your contributions.

Stomata are essential for regulating the exchange of water and energy between plants and the atmosphere. In the context of climate warming, especially in extremely arid regions, the knowledge of stomatal conductance variation patterns is fundamental to the study of crop evapotranspiration, productivity and drought resistance characteristics. The accurate simulation of stomatal conductance in this region is an important prerequisite for the optimal regulation of the crop growth environment. In this study, a two-year field experiment was carried out in vineyards in an extremely arid region. The Jarvis model and BWB model were used to evaluate the daily changes in stomatal conductance. The results showed that stomatal conductance was significantly correlated with environmental factors (temperature difference between leaf and air (ΔT), photosynthetically active radiation and air temperature). The Jarvis and BWB models performed well. However, the response function of the environment factor in the Jarvis model can affect the model performance. The ΔT effectively improved the model, and the modified Jarvis model outperformed the modified BWB model. The R2 and model slope b of the modified Jarvis model increased by 45.18–70.37% and 2.51–3.12%, respectively. RMSE and MAE decreased by 38.98–43.12% and 42.69–44.35%, respectively. Overall, the Jarvis3–ΔT model had a good effect on the simulation of the daily change of stomatal conductance during the critical period of grape growth, and the Jarvis3–ΔT model was the best stomatal conductance model in this study. The results of the study are of great significance for further improving the sustainable use of water resources in grapevines in extremely arid regions. Full article

The water–zeolite amount–burial depth coupling regulation strategy of high-quality and high-yield tomatoes was explored with drip irrigation under mulch. Greenhouse planting experiments were performed to monitor and analyze the tomato growth, physiology, yield, quality, and water use efficiency (WUE). The suitable amounts of the water–zeolite amount–burial depth for the tomato growth were determined through the analytic hierarchy process (AHP). The results showed that the effects of increasing the water of the intercellular CO2 concentration (Ci), nitrate content (NO), vitamin content (VC), and soluble solids (SS), increasing the WUE, increasing the zeolite amount of the NO, and increasing the zeolite burial depth of the Ci and SS, were inhibited. The effects of increasing the zeolite amount of the plant height (Kh), stem thickness (Kt), total root length (Rl), total root volume (Rv), root average diameter (Rd), net photosynthetic rate (Pn), stomatal conductivity (Gs), organic acid (OA), VC, yield (Ay), and WUE, and of increasing the zeolite burial depth of the Kh, OA, dry matter quality (Ad), and WUE, were promoted first and then inhibited. The other indicators showed a positive response to increasing the water, zeolite amount, and burial depth. The influence of the water (W), zeolite amount (Z), and zeolite depth (H) on the Kt, Tr, Rl, and Rd, was W > H > Z, and that of the Kh, Gs, Pn, Ci, Ra, Rv, OA, VC, NO, SS, Ad, Ay, and WUE was W > Z > H. The order of weight of each index, based on the AHP, is as follows: Ay > WUE > NO > OA > Ad > Kh > Kt > VC > SS > Pn > Rv > Rd > Tr. The highest comprehensive score was W70–90Z6H15, and the most suitable water conditions for the tomato planting under drip irrigation were 70–90% field capacity, 6 t/hm2 zeolite, and 15 cm depth of zeolite.

The contradiction between water supply and demand has become increasingly prominent due to the large agricultural water consumption and low irrigation water use efficiency (IWUE) in the extremely arid area of Xinjiang, which needs to be solved by efficient irrigation. In this study, the effects of different irrigation levels (the lower and upper limits of irrigation (LULI) were 50–80%, 60–90%, and 70–100% of the field capacity (FC), respectively) under two irrigation methods (root zone irrigation (RZI) and furrow irrigation (FI)) on the photosynthetic physiology and yield of grape were analyzed to explore suitable irrigation schemes in extremely arid areas. The results show that the diurnal variation curve of the net photosynthetic rate (Pn) of grape leaves in the extreme arid region was not sensitive to the response of irrigation methods. However, RZI could improve the apparent quantum efficiency and maximum photosynthetic rate by 60.00% and 31.25%, respectively, reduce the light compensation point by 17.91%, and alleviate the photosynthetic lunch break phenomenon. Under FI, the physiological indexes of leaves increased with the increase in the LULI, while the Pn and SPAD values were the largest under RZI when the LULI was 60–90% of FC. The daily average Pn value of T2 in 2021 and 2022 ranged from 12.93 to 17.77 μmol·m−2·s−1. Compared with FI, RZI significantly improved the leaf water potential, Pn, and SPAD values by increasing the soil water content (SWC) of the 40–80 cm soil layer by 5.04–8.80%, which increased the yield by 6.86–18.67%. The results show that the yield and water use efficiency reached the peak when the LULI was 60–90% of FC under RZI, which could provide theoretical support for efficient irrigation of vineyards in extremely arid areas.
