平菇是一种人们喜爱的蔬菜,其栽培技术不甚复杂而被广泛种植,但其在生长过程中经常发生一些生理性病害,既影响产量又影响品质,现逐一加以分析。1.幼菇枯萎小菌盖突然变黄、发软,子实体基部变粗、水肿发亮,继而枯萎腐烂。主要原因有:突然受到高温、低温刺激,菌体代谢紊乱;采菇时松动幼菇,引起菌丝断离。预防措施:严禁直接在刚刚形成的子实体的菇床上喷水;防止温度在短时间内的剧烈变化;采菇时切忌用力硬拔,以免牵动周围的幼菇。2.菌丝徒长其原因是配料时水分过多、料面湿度太大;管理不周到,气温高、料温高、二氧化碳
Pleurotus ostreatus is a kind of favorite vegetable, its cultivation technique is not complicated and widely planted, but its physiological processes often occur in the growth process, affecting both yield and quality, are to be analyzed one by one. 1 young mushroom withered small cap suddenly turn yellow, soft, fruiting body base thicker, edematous shiny, then wilt decay. The main reasons are: Suddenly by high temperature, low temperature stimulation, cell metabolism disorders; mushrooms loose mushrooms, causing mycelium off. Precautionary measures: It is forbidden to spray water directly on the mushroom bed of the fruiting bodies that have just been formed; to prevent the drastic changes of temperature in a short period of time; and to avoid harming the surrounding young mushrooms when adopting mushrooms. 2. mycelium leg up due to excessive moisture ingredients, material surface humidity is too large; poor management, high temperature, high temperature, carbon dioxide
