Objective: To explore the effects of different organic fertilizers on the growth and quality of Ganoderma lucidum, thereby providing a scientific basis for fertilizer selection in under story economic planting and optimizing cultivation practices.[Methods] A forest farm was selected as the experimental site, with red Ganoderma lucidum（cultivated via fungal substrate bags） and black Ganoderma lucidum（cultivated via inoculated logs） as test crops. Fungal substrates were prepared according to respective cultivation methods and transplanted into field ridges. Three organic fertilizers（labeled A1-A3） were formulated using decomposed apple pomace, cow manure, sheep manure,wheat bran, cottonseed hulls（A3 only）, and mixed wood chips（A3 only）. Fertilization was applied to designated plots at predefined intervals and dosages, while a control group（A4） received no organic fertilizer. Growth parameters and quality indicators of both Ganoderma lucidum varieties were monitored and recorded throughout the trial. Results: The A2 treatment group exhibited optimal growth: red Ganoderma lucidum achieved a cap diameter of 9.3cm and biomass of 200 g/m², while black Ganoderma lucidum reached 9.5 cm and 250 g/m², respectively. Quality analysis revealed that red Ganoderma lucidum in A2 contained 0.5% ash, 7.2 g/100 g polysaccharides, and 3.52mg/g triterpenoids, whereas black Ganoderma lucidum contained 0.3% ash, 4.6 g/100 g polysaccharides, and 3.20mg/g triterpenoids. Conclusion. Organic fertilizers of A2 significantly enhance both yield and quality of understory Ganoderma lucidum in economic cultivation systems.
