The Combination of Shading and Potassium Application Regulated the Bulb Active Ingredients Accumulation in <i>Fritillaria thunbergii</i> Miq. by Affecting Rhizosphere Microecology.

ABSTRACT: The bulbs of the lily plant Fritillaria thunbergii Miq. possess substantial medicinal properties for relieving coughs and clearing the lungs. However, excessive pursuit of yield during cultivation has led to a decrease in medicinal ingredients. Therefore, we aimed to investigate the effects of two single-factor treatments, shading (SK0) and potassium application (S0K), and their coupling treatment (SK) on bulb biomass and medicinal substance content, along with the role of rhizosphere microorganisms. Shading increased the content of active ingredients in bulbs by approximately 11.7% while decreasing bulb biomass by approximately 11.3%. SK treatment mitigated the biomass reduction caused by SK0 treatment while enhancing the accumulation of active ingredients in F. thunbergii,
