Faced with the increasingly serious problem of water scarcity, developing precise irrigation strategies for crops in saline alkali land can effectively reduce negative effects low resource utilization. Using a model to simulate dynamic changes soil and salt environment root zone fragrant pear trees land, verifying them from production practice perspective comprehensive benefits as goal, optimize amount technology elements fruit trees, broaden evaluation decision-makers, have important significance improving yield efficiency forestry industry arid semi-arid areas worldwide. In this study, two-year field experiment based on three levels (3000, 3750, 4500 m 3 ·ha −1 ) four emitter discharge rates (1, 2, 3, 4 L·h was conducted Xinjiang, China. The content (SWC) salinity (SSC) dynamics were simulated during fertility period using numerical HYDRUS-2D data. results showed that R 2 , mean squared error (RMSE), Nash–Sutcliffe coefficient (NSE) (soil SSC) reached 0.89–0.97 (0.91–0.97), 0.02–0.16 cm ·cm -3 (0.22–1.54 g·kg ), 0.76–0.95 (0.68–0.96), respectively, indicating strong performance model. A positive correlation observed between infiltration depth. Moderately increasing could leach at depth 80–100 maintain main 0–80 cm, benefiting growth development system pear, well quality above-ground fruits. optimized quantified multi-objective optimization methods, normalization processing, spatial analysis methods maximize yield, weight, soluble solids, net profits. When profits simultaneously 90% their maximum value, ranges 4274–4297 3.79–3.88 respectively. Our study provides new insights into regulating environmental factors assessing impact management under precision strategies, profoundly influences decision-making forest fruits zones perspective.
