Abstract
To rationally utilize different fly ashes for aeolian sandy soil improvement, this study conducted pot experiments with pulverized coal fly ash (PC) and circulating fluidized bed fly ash (CFB) at various application rates. Soil physicochemical properties (before and after the experiment) and pakchoi growth were measured to explore the improvement effects. Results showed that both fly ashes improved aeolian sandy soil physical properties; CFB outperformed PC in regulating all physical properties except bulk density and enhanced soil fertility more effectively. CFB had a higher pH than PC, and pakchoi growth was optimal at 5% CFB addition. Rational utilization of these fly ashes realizes waste recycling, ecological restoration, and supports national ecological civilization construction.
