Mechanistic study on integrated water-fertilizer management to alleviate Na⁺ toxicity and enhance salt tolerance and yield of pakchoi under salt stress.

ABSTRACT: The cultivation of salt-tolerant pakchoi is a promising strategy for utilizing coastal saline soils. However, supporting agronomic technologies are remain underdeveloped. This study investigates how coordinated water-fertilizer regulation mitigates sodium (Na⁺) toxicity under salt stress, thereby enhancing salt tolerance and yield in pakchoi and providing a scientific basis for optimizing agronomic management. A pot experiment was conducted with three irrigation methods (conventional, drip, and mulched drip) and three fertilizer types (conventional, controlled-release, and mixed), under soil salt stress adjusted by sodium chloride (NaCl) to 0.15% salinity by weight. The results showed that MP treatment (mulched drip irrigation + mixed fertilizer) can significantly improve yield
