This study investigated the effects of various combinations of potassium humate and raw wheat straw (RWS) treatments on the growth, yield, and quality of (Jacq.) P. Kumm across two growing seasons. A total of seven treatment combinations (H0_RWS, H0.25_RWS, H0.5_RWS, H0.75_RWS, H1_RWS, H1.25_RWS, and H1.5_RWS) were applied to evaluate eleven traits, including soluble sugar content (SSC), fruiting body yield (FBY), biological efficiency (BE), and biochemical attributes. The analysis of variance revealed significant effects of both season and treatment on all traits, with notable interactions. The H0.5_RWS treatment demonstrated the highest improvements, increasing SSC by 15.3%, FBY by 18.6%, and vitamin C (VC) by 12.4% compared to the control. Utilizing principal component analysis (PCA) showed that the first two components explained 89.5% of the variance, with strong associations between SSC, VC, FBY, total phenolic content (TPC), BE, and peroxidase activity (POD) on PC1. The H0.5_RWS treatment was identified as the most effective for enhancing these parameters. Heatmap and radar plot analyses further confirmed the positive influence of moderate potassium humate doses, while higher doses resulted in reduced benefits. Correlation analysis showed strong positive relationships between yield and both total sugars (R² = 0.99) and BE (R² = 0.97). The results emphasize the substantial importance of balanced potassium humate application in enhancing the production and nutritional quality of , providing valuable insights to optimize the cultivation practices of this species.
本研究调查了腐植酸钾与生小麦秸秆（RWS）不同组合处理对两个生长季节中（Jacq.）P. Kumm生长、产量和品质的影响。共应用了七种处理组合（H0_RWS、H0.25_RWS、H0.5_RWS、H0.75_RWS、H1_RWS、H1.25_RWS和H1.5_RWS）来评估包括可溶性糖含量（SSC）、子实体产量（FBY）、生物学效率（BE）和生化属性在内的11个性状。方差分析显示季节和处理对所有性状均有显著影响，且存在显著的交互作用。与对照相比，H0.5_RWS处理表现出最高的提升，使SSC提高了15.3%，FBY提高了18.6%，维生素C（VC）提高了12.4%。主成分分析（PCA）表明，前两个成分解释了89.5%的方差，在主成分1上，SSC、VC、FBY、总酚含量（TPC）、BE和过氧化物酶活性（POD）之间存在强关联。H0.5_RWS处理被确定为增强这些参数最有效的处理。热图和雷达图分析进一步证实了适量腐植酸钾剂量的积极影响，而较高剂量则导致效益降低。相关性分析表明产量与总糖（R² = 0.99）和BE（R² = 0.97）之间均存在强正相关关系。结果强调了平衡施用腐植酸钾对提高（Jacq.）P. Kumm产量和营养品质的重要意义，为优化该物种的栽培实践提供了有价值的见解。
