Cultivating Suaeda salsa (S. salsa) is a promising strategy for the improvement and development of saline wastelands. However, absence scientifically reasonable water fertilizer management system has long hindered large-scale utilization Therefore, we performed field experiments two consecutive years to investigate effects water-nitrogen coupling on biomass, forage quality, salt absorption capacity, soil effect, economic benefits S. salsa. The optimal nitrogen dosages multi-objective optimization were determined using multiple regression spatial analysis methods. Three irrigation levels established experiment based 0.35 (W1), 0.50 (W2), 0.65 (W3) local ETo (Where denotes reference evapotranspiration calculated FAO-56 recommended by Food Agriculture Organization). three application 150 (F1), 250 (F2), 350 (F3) kg ha−1 in complete combination design. At same level, biomass W3 level highest. reduction, productivity at lower than those W2 W1 was when F2, absorption, net profit, all reached their maximum values, highest F3 level. amount applied each parameter different, so it impossible obtain productivity, profit time. needed, volume range 3350.11–3485.97 m3 ha−1, rate 273.49–326.66 ha−1. These findings provide scientific basis cultivation extreme arid region, which helpful saline-alkali land.
