目前,平菇栽培污染霉菌常见有木霉、青霉、链孢霉、黄曲霉和黑曲霉。它们分布广,生命力强,在高温、高湿、偏酸和通风不良的条件下迅速繁殖蔓延,霉菌侵染培养料,与平菇菌丝争夺营养,有的分泌毒素,影响平菇的生长和发育,其中以木霉菌危害最为严重,因此,能否有效地防止霉菌污染,是平菇栽培成功与否的关键。 防治霉菌应预防为主,综合防治,以确保平菇正常生长发育,达到优质高产目的。 1、正确选用和处理原料。生料 Currently, mushroom cultivation of fungal mold are common Trichoderma, Penicillium, Neurospora, Aspergillus flavus and Aspergillus niger. They are widely distributed, strong vitality, rapid propagation and spread under the conditions of high temperature, high humidity, partial acid and poor ventilation, fungal infection of culture materials, competing for nutrition with Pleurotus ostreatus, and some secreted toxins, affecting the growth of Pleurotus ostreatus and Development, of which Trichoderma harms the most serious, therefore, can effectively prevent mold pollution, is the key to the success of mushroom cultivation. Prevention of mold should be based prevention, comprehensive prevention and control to ensure the normal growth and development of Pleurotus ostreatus, to achieve high quality and high yield. 1, the correct selection and processing of raw materials.
