不同外援营养液对白灵菇生长的影响

以白灵菇菌株TN01为试材,选取香菇、杏鲍菇、白玉菇3种食用菌菇根为原料配制外援营养液,测定各营养液主要成分含量,并研究了不同类型与浓度营养液对白灵菇菌丝及子实体生长的影响,以期为白灵菇的高产栽培技术提供参考依据。结果表明:与常规PDA培养基相比,适量加入白玉菇菇根提取液可提高白灵菇菌丝生长速度;添加外援营养液对子实体的农艺性状影响不大,对产量有一定的促进作用,其中施用香菇菇根提取液的白灵菇子实体产量最高,小区总产量与对照相比提高了54.6%。施用香菇菇根提取液后对白灵菇子实体中的硝酸盐含量及蛋白质含量有提升的效果,但对亚硝酸盐及粗纤维含量无促增长的效果。

Effects of Differrent Foreign Aid Nutrient Solution on the Growth of Pleurotus nebrodensis

Taking strain TN01 of Pleurotus nebrodensis as test matrial, the main components of foreign aid nutrient solutions from three mushroom roots were determined.And the effect of different kinds and concentrations of foreign aid nutrient solution on the mycelial and fruiting body growth of Pleurotus nebrodensis was studied, in order to provide the basis for high yield cultivation techniques of Pleurotus nebrodensis.The results showed that the mycelial growth rate of Pleurotus nebrodensis was obviously improved compared with the PDA medium when the white Hypsizygus marmoreus root extract solution was added into the solid medium.The traits of fruiting bodies from Pleurotus nebrodensis added foreign aid nutrient solution changed little, while the growth of Pleurotus nebrodensis fruiting body was promoted by foreign aid nutrient solution, and the highest fruiting body yield of Pleurotus nebrodensis was obtained by solid medium mixed with Lentinus edodes root extract solution.Besides, the total production was improved 54.6% than that of the control.Nitrate content and protein contents of the Pleurotus nebrodensis fruiting bodies were increased in the groups treated by adding Lentinus edodes root extract solution,while the nitrite contents and crude fiber content of the Pleurotus nebrodensis fruiting bodies were not raised.
