The bulbs of the lily plant 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 , up to 1.2 times higher than that of SK0 treatment. In rhizosphere soil, (ANPR), , , and exhibited significant positive correlations with medicinal components, among which ANPR, and were responsive to SK treatments. Also, (BCP) and responded to changes at different growth stages of The relative abundance of these microorganisms was associated with the alterations of soil factors resulting from shading or K application. Our results indicate that these microorganisms are beneficial to the growth of bulbs and the synthesis of active components in The combination of shading and K application may regulate the accumulation of medicinal substances in by modulating the structure of the soil microbial community. Our results serve as a reference for soil improvement for medicinal plant cultivation.
百合科植物Miq.的鳞茎具有显著的止咳润肺药用特性。然而，在栽培过程中对产量的过度追求导致了药用成分的减少。因此，我们旨在研究两种单因素处理（遮光（SK0）和施钾（S0K））及其耦合处理（SK）对鳞茎生物量和药用物质含量的影响，以及根际微生物的作用。遮光使鳞茎中活性成分的含量增加了约11.7%，同时使鳞茎生物量减少了约11.3%。SK处理减轻了SK0处理导致的生物量减少，同时增强了活性成分在[此处原文缺失部分内容]中的积累，比SK0处理高出1.2倍。在根际土壤中，[此处原文缺失部分内容]（ANPR）、[此处原文缺失部分内容]、[此处原文缺失部分内容]和[此处原文缺失部分内容]与药用成分呈显著正相关，其中ANPR、[此处原文缺失部分内容]和[此处原文缺失部分内容]对SK处理有响应。此外，[此处原文缺失部分内容]（BCP）和[此处原文缺失部分内容]对[此处原文缺失部分内容]不同生长阶段的变化有响应。这些微生物的相对丰度与遮光或施钾导致的土壤因子变化有关。我们的结果表明，这些微生物有利于[此处原文缺失部分内容]鳞茎的生长和活性成分的合成。遮光和施钾的组合可能通过调节土壤微生物群落结构来调控[此处原文缺失部分内容]中药用物质的积累。我们的结果为药用植物栽培的土壤改良提供了参考。
