平菇以其适应性强,容易栽培而成为我国当前发展最快的食用菌之一,但在平菇生产过程中出现的一些生理性病害严重影响着它的品质和产量,必须找出原因并加以防止。菌丝徒长原因是配料时水分过大,料面潮气太浓,管理不及时,气温高,料温高,二氧化碳浓度高。在这样的小气候环境影响下,刺激菌丝徒长,在培养料表面形成大量白色绒毛状气生菌丝,有时成为厚厚的一层菌膜,推迟菇蕾的出现,成菇少,产量低。防止措施:培养料加水量要掌握在1:1.2-1.5,菌丝培养阶段要注意菇房的通气量,及时排除室内的潮气;若菌丝徒长,应及时用刀划破或用耙破坏徒长的菌丝体,抑制料面菌丝徒长,促使菌块内部菌丝生长。
Pleurotus ostreatus has become one of the fastest growing edible mushrooms in China due to its adaptability and easy cultivation. However, some physiological diseases that occur during the production of Pleurotus ostreatus seriously affect its quality and yield, and must find out why Prevent it. Hypothesis is due to moisture when the ingredients is too large, the moisture level is too thick, the management is not timely, high temperature, high temperature, high concentration of carbon dioxide. Under the influence of such a microclimate environment, mycelium growth is stimulated, and a large amount of white fluffy aerial mycelium is formed on the surface of the culture material, which sometimes becomes a thick layer of bacteria membrane, and the appearance of mushroom buds is delayed. Preventive measures: to cultivate the amount of water to be mastered in 1: 1.2-1.5, mycelium culture stage should pay attention to the ventilation of mushroom house, and timely removal of indoor moisture; if mycelium leggy, should be promptly cut with a knife or rake to damage the leggy Of the mycelium, inhibition of surface mycelium leggy, prompting mycelium growth within the bacteria.
