摘要：

This study introduces a composite amendment, containing CaSO₄, MgSO₄, Fe₂(SO₄)₃, and Palygorskite (PGS), for concurrently improving saline-alkali soil physicochemical properties and promoting crop growth via in situ soil regulation and nutrient release. Experimental results demonstrated Layered Double Hydroxide (LDH) structure formation within the amended soil after 20 days, a key in situ mineralization mechanism absent in the control. This process significantly reduced soil pH from 9.85 to 7.86 (a 20.2 % decrease) and drastically lowered...
