大亮子河国家森林公园大型真菌的生态分布与资源评价

Macrofungi in the Daliangzihe National Forest Park of Heilongjiang Province were investigated,and 170 species of macrofungi were identified.These fungi belong to 9 orders,31 families and 90 genera.Among them,50 species were edible mushrooms,31 species were medicinal fungi,13 species were poisonous mushrooms,42 species were mycorrhizal fungi and 56 species were wood decaying fungi.The distribution of these fungi in the korean pine and broad-leaved mixed forest,korean pine and spruce mixed forest followed certain patterns,the population structures and abundance of these fungi were closely related to some forest factors including the structure of stands,soil,altitude and slope etc.

高氧化还原电位酸性水的制备及在食用菌生产中杀菌试验初报

高氧化还原电位酸性水(EOW)是电解加有NaCl的蒸馏水时,在阳极产生氧化还原电位(ORP)≥1.040V、pH≤2.0,有效氯含量<0.080g/L的水溶液。试验结果表明,当水中NaCl的含量为15.0g/L,电解10min后,水溶液中ORP随时间升高,阳极区溶液的pH值随时间延长而降低。水溶液杀菌试验表明,在20℃下,ORP为1.000V的电解水溶液,对绿色木霉、匍枝根霉、黑曲霉、酵母作用40min,杀灭率达100%。其杀菌效果随pH值降低、ORP升高、温度上升而增强,因有机物存在而减弱,温度升高、振摇及铁等金属离子存在时其分解速度加快。高浓度EOW溶液对金属有腐蚀性,对皮肤有刺激性。可应用于食用菌生产中空间及生产环境消毒。
