Seedling growth of Glycyrrhiza uralensis is severely inhibited by salt stress, limiting its cultivation in saline-alkali soils. This study aimed to evaluate the mitigative effects of lanthanum nitrate (La(NO₃)₃) and develop a predictive model for the salt stress response. The results showed that the photosynthesis, anti-oxidative stress, growth and relative content of pharmacological active components of G.uralensis were significantly inhibited under salt stress. Under 0.75 mM exogenous La(NO3)3 treatment, licorice under salt stress showed photosynthetic compensation recovery, activation of antioxidant defense, synergistic improvement of bio-mass and medicinal quality. At the same time, this study innovatively constructs the NRBO-LSSVM-ABKDE coupling prediction model, and its prediction accuracy is significantly better than the traditional algorithm, and the mitigation effect of La(NO3)3 on G.uralensis was successfully verified. These findings not only confirm the efficacy of La(NO₃)₃ in alleviating salt stress in G. uralensis but also provide a powerful predictive tool for assessing plant stress responses, offering a new strategy for sustainable agriculture in salt-affected areas.
