To quantitatively analyze the stress-resistant physiological characteristics of maize under high-concentration salt stress, a combination of statistical analysis and quantitative recursive analysis is selected to conduct salt stress experiments on maize seedlings. 20 treatments are set up, with each treatment consisting of 5 pots and 3 plants per pot. The experiment is conducted without the involvement of any animals. Physiological characteristics data of maize seedlings under various salt stresses are collected and subsequently processed and analyzed using SPSS software. A big data distribution model for salt stress is set up, relevant rules are mined through recursive graphs, stress-resistant physiological traits are evaluated, random distribution characteristics of salt alkali-resistant maize stress physiological sequences are calculated and the adverse physiological morphology of salt alkali-resistant maize is assessed. Overall, valuable insights into the physiological responses of maize seedlings to different salt stresses are obtained through this research, which can contribute to future studies on stress-resistant crops. The findings indicated that stress caused by high concentrations of salt would affect the levels of Malondialdehyde, proline, and soluble sugar, as well as the functionality of antioxidant enzymes in maize. Among them, under NaHCO3 salt stress, the content of MDA, proline, and soluble sugars in maize seedlings showed a trend of first decreasing, then increasing, and then decreasing again, while the content of SOD in maize seedlings showed an upward trend. Under the stress of NaHCO3 and NaCl, the SOD activity in the leaves of Changfeng 1 and Demeiya 1 exhibited a rising trend as the stress time was extended. The activity of SOD in the two varieties that were treated with NaHCO3 reached its maximum value after 36 h of stress. Under salt stress, the direct participation of the increase in δ-OAT activity in the clearance of MDA is observed. P5CS and δ-OAT can enhance the compressive strength of corn by interacting with various other indicators. Research methods are capable of effectively analyzing the stress-resistant physiological traits of maize when subjected to high-concentration salt stress. Compared to previous studies, the study extends the duration of stress and analyzes the physiological changes of maize in resisting salt stress. Not only that but also multiple comparisons of salt stress have been added to gain a clearer understanding of the physiological changes of maize under different salt stresses.
