Accumulation and Distribution Characteristics of Cd in the Soil-<i>Lilium</i> System and the Remediation Mechanism by Soil Amendments.

ABSTRACT: This study investigated the accumulation and distribution of cadmium (Cd) in the Soil-Lilium system and researched the effects and mechanisms of applying oyster shell powder (OSP) and organic fertilizer (OF) on reducing Cd accumulation and enhancing Lilium yield. The results showed that the total Cd content in soils across different planting regions was below 0.3 mg·kg^-1, while the Cd content in Lilium bulbs ranged from 0.44 mg·kg^-1 to 1.35 mg·kg^-1, indicating a consistent trend of Cd accumulation in Lilium bulbs. Cd contents were highest in the leaves and lowest in the bulbs, suggesting a strong translocation of Cd from the roots to the aerial parts. Both OSP and OF treatments improved Lilium growth and reduced Cd accumul
