Key Production Technology Points for Flat-Bed Cultivation and Successive-Generation Cultivation of the Elm Oyster Mushroom (Pleurotus citrinopileatus)
The elm oyster mushroom (Pleurotus citrinopileatus), due to its strong growth vigor, good stress resistance, ease of cultivation and promotion, and high biological efficiency, has very broad development prospects in Shandong Province. Shandong Province is a major cotton-growing province, and in recent years the cotton planting area has risen sharply, with cottonseed hulls being of high quality and low price. The following is an introduction to the production technology for cultivating the elm oyster mushroom using cottonseed hulls as the main substrate, employing fermented substrate flat-bed cultivation and successive-generation cultivation. I. Spawn Production 1. Spawn Selection Select strains with strong growth vigor, good stress resistance, high and stable yields, and a broad temperature adaptation range, such as Yuhuang-1 and Yuhuang-2. The mycelial growth temperature is 5-35 degrees, with 20-30 degrees being suitable; the fruiting body differentiation and growth temperature is 10-30 degrees, with the optimum temperature being 8-25 degrees. It is tolerant to carbon dioxide. Under conventional cultivation, the biological yield can reach 150%, and under successive-generation cultivation, the conversion rate can reach 200%. It is an excellent strain suitable for cultivation in Shandong Province.
