5. Conclusion
In conclusion, the cultivation ofM. azedarach could reduce soil salinity and promote soil nutrient
cycling. M. azedarachalleviated salt stress by up-regulating the expression of metabolites
such as sugars, amino acids and flavonoids. There was a synergistic
effect between alkaline phosphatase and traumatic acid in improving the
salt tolerance of M. azedarach . This research provided a solid
basis for clarifying the adaptation and amelioration mechanism ofM. azedarach to salt stress on saline-alkali land.
