摘　　要：平109是陕西省微生物研究所培育出的一株适宜关中地区栽培的高产平菇菌种。利用平菇具有较强富硒能力的特点,向培养料中添加一定浓度的亚硒酸钠,对平109进行富硒栽培试验。结果表明,在以棉籽壳85%、麸皮12%、蔗糖1%、过磷酸钙1%、石膏粉1%为栽培原料的培养料中加入40 mg/kg亚硒酸钠,菌丝体阶段培养温度为28℃时,硒的富集量最高,同时其生物量亦有所提高。无机硒不仅可以提高平菇的产量,还可以使硒在菇体内富集,因此可以用于平菇富硒栽培。″Ping 109″, a strain of oyster mushroom with high-yield, is bred by Shaanxi Provincial Institute of Microbiology which is suitable for cultivation in Guanzhong regions. Based on the strong ability of oyster mushroom in selenium enriching, cultivation experiment was conducted by adding certain concentration of sodium selenite to the culture medium of ″ Ping 109″. The results showed that the highest enrichment of selenium was obtained when 40 mg/kg of sodium selenite was added in the culture medium consisting of 85% of cotton seed hull, 12% of wheat bran, 1% of sucrose, 1% of calcium superphosphate, 1% of gypsum powder,and the culture temperature during mycelium stage was 28 ℃. Meanwhile, under this culture condition, the biomass of ″Ping 109″was also improved. The results suggest that adding inorganic selenium to culture medium is not only able to improve the production of oyster mushroom, but also accelerates the enrichment of selenium within mushroom. Supplementation of inorganic selenium is recommended in cultivation of selenium-enriched oyster mushroom.
