摘　　要：为实现广东地区竹荪的周年生产,以棘托竹荪为研究对象,以传统菌棒制作配方为对照(处理1),探讨改良配方(处理2)以及在改良配方中加入不同量的硒元素(0.5 mg/kg,处理3;1.0 mg/kg,处理4;2.0 mg/kg,处理5)对广东秋冬季栽培的竹荪生长的影响。结果表明:1)在改良配方中除处理2外,处理3、4、5的菌丝生长速度均快于传统配方(处理1),且菌丝颜色更洁白、均匀度较好,长势评分较高;2)改良配方的竹荪蛋数量、产量、生物转化率均高于传统配方,其中处理4、处理5竹荪蛋数量分别为7.56个/棒、7.53个/棒,显著高于其他处理;3)处理4、处理5的竹荪蛋硒元素含量分别为1.5 mg/kg、2.08 mg/kg,显著高于其他处理,处理4的竹荪蛋蛋白质含量、水解氨基酸含量最高,分别为23.38 g/100g、22.21 g/100g;4)处理4竹荪蛋超氧化物歧化酶、过氧化物酶、过氧化氢酶活性较高,处理5的竹荪蛋谷胱甘肽过氧化物酶活性较高。研究结果可为广东地区竹荪秋冬季节栽培提供参考。To achieve the whole-year production of Dictyophora echinovolvata in Guangdong,the traditional mushroom spawn formula is used as the control(treatment 1)to explore the improved formula(treatment 2)and the addition of different content of selenium to the improved formula(0.5 mg/kg,treatment 3;1.0 mg/kg,treatment 4;2.0 mg/kg,treatment 5)on the growth of D.echinovolvata in autumn and winter.The results show that:1)Except for treatment 2,the mycelium growth rates of treatment 3,treatment 4,treatment 5 are faster than that of the traditional formula(treatment 1),and the mycelium color is whiter and uniform,with higher growth score;2)The number,yield and bioconversion rate of D.echinovolvata eggs in the improved formula are higher than those in the traditional formula.The number of eggs in treatment 4 and treatment 5 are 7.56/stick and 7.53/stick,respectively,which are significantly higher than those in other treatments;3)In treatment 4 and treatment 5,the selenium contents of D.echinovolvata eggs are 1.5 mg/kg and 2.08 mg/kg,respectively,which is significantly higher than that of other treatments.In treatment 4,the protein content and the hydrolytic amino acid content of D.echinovolvata eggs are the highest,which are 23.38 g/100 g and 22.21 g/100 g,respectively;and 4)The activities of superoxide dismutase,peroxidase and catalase in treatment 4 are higher than those in treatment 5.The results could provide references for the cultivation of Dictyophora in autumn and winter in Guangdong.
