平菇是一种适应性广、抗逆性强、生产周期短、生物转化率高的食用菌。平菇菌丝虽然具有生长速度快,并且抗杂菌能力强的优点,但平菇菌丝在不良条件下发菌生长,菌丝活力更容易衰退,以致菌丝更容易带毒带菌,所以对于平菇的菌种提纯复壮尤为重要,由于平菇栽培和制种简单,多数菇农自制平菇菌种,保藏母种,特别对一些相对有经验的部分菇农,认为平菇栽培容易,制种简单,使用保藏不好的母种,盲目转接母种试管,或者多代繁殖,或不正确的进行营养繁殖,加上培养基配置比例不当以及发菌条件的不足
Pleurotus ostreatus is a kind of edible fungus with wide adaptability, strong resistance, short production cycle and high biological conversion rate. Pleurotus ostreatus mycelium has the advantages of fast growth and good antibacterial ability, but mycelium growth under unfavorable conditions, mycelium activity is more likely to decline, so that mycelium is more likely to carry poisonous bacteria, so for Pleurotus mushroom purification and rejuvenation is particularly important, due to simple cultivation and seed production Pleurotus ostreatus, the majority of Mushroom homemade mushroom strains, preservation of mother species, especially for some relatively experienced part of Mushrooms, mushroom cultivation that easy Simple species, the use of poorly preserved mother species, blind transfer of the mother of the test tube, or multi-generational breeding, or improper vegetative propagation, coupled with improper distribution of the medium and the lack of hair conditions
