| 英文摘要 | Salinity is one of the most decisive environmental factors limiting crop productivity, especially in arid and semi-arid regions. The objective of this study was to evaluate the growth depression of spring maize (Zea mays L.) due to salinity stress caused by different drip irrigation regimes in an arid saline area. A two-year field experiment was conducted in the Hetao Irrigation District, northwest China in 2019 and 2020. The study soil was moderately saline with ECe (electrical conductivity of saturated soil extract) of 8.04 dS m(-1). Three threshold values of soil matric potential (SMP), -10, -30, and -50 kPa, were used to trigger a 10-20 mm drip irrigation of spring maize. Nine plots were arranged in a randomized block design (with triplication for each SMP level). Results showed that the lower soil salinity caused by higher SMP levels significantly increased crop photosynthetic capacity and reduced salt cations (K+, Na+, Ca2+, Mg2+) concentrations in plant organs, thereby increasing aboveground biomass and grain yields. Gas exchange parameter values first increased and then decreased in the R1-R5 stage (76-115 DAP) except for net photosynthetic rate (P-n) of -10 kPa treatment. Four salt cations in the aboveground parts were mainly distributed in stems and leaves, followed by grains. However, there was no significant difference in aboveground cationic accumulation among treatments. Correlation analysis indicated that gas exchange parameter values were negatively correlated with concentrations of K+, Na+, Ca2+, and Mg2+ in aboveground plant organs at harvest, indicating that P-n could quantitatively reflect the salt ionic toxicity in crops to a large extent. Considering photosynthesis, salt cations absorption, and water use efficiency, an SMP threshold of -30 kPa is recommended for drip irrigation of maize in this arid saline condition. These findings can provide a theoretical basis and technical reference for the promotion of mulched drip irrigation under the arid saline condition. |
