在金针菇生产中制种及载培料上常发生杂菌污染,轻则减产,重则绝收。常见的杂菌有细菌、酵母菌和霉菌,防治措施: 一.制种严把无菌关:①原种不带杂菌;②培养基(料)及接种用具要彻底灭菌;③接种过程要严格无菌操作。 二.选用抗逆性强的菌株。使用菌龄短,生活力强,长势旺盛的优质母种和原种,以使接种后尽快形成优质,抵制杂菌浸染。
In the production of Flammulina velutipes and pest-feeding bacteria often occur pollution, ranging from the reduction of production, re-harvest. Common bacteria are bacteria, yeasts and molds, prevention and control measures: a seed production strict sterile: ① original species without bacteria; ② medium (materials) and vaccination appliances to be completely sterilized; ③ vaccination process To be strictly aseptic Two. Use strong strains resistant. Use the shorter age, strong vitality, strong growth of high-quality mother and the original species, so as soon as possible after inoculation to form high-quality, to resist the spread of bacteria.
