随着食用菌栽培技术的日益发展,平菇由熟料栽培发展为生料栽培——原料经过处理后播种发菌。生料栽培平菇能否成功,关键在于能否在菌丝生长阶段有效地防止杂菌污染,使平菇菌丝得以迅速生长,并占领整个菌床的培养料。常与平菇菌丝争夺养料的竞争性杂菌如绿霉、青霉、毛霉、根霉、曲霉、链孢霉等,其一旦发生,短时间内便大量繁殖,占领料面并向内部蔓延,与平菇菌丝争夺营养,分泌毒素,抑制其生长,导致局部甚至整个菌床污染而造成栽培失败。因此,生料栽培平菇防杂菌污染是个关键性的问题,在高温季节栽培平菇尤为如此。
With the growing development of mushroom cultivation, mushroom cultivation from clinker development for the raw material cultivation - the raw material after treatment, sowing bacteria. Raw material cultivation mushroom success, the key lies in the mycelium growth stage can effectively prevent bacterial contamination, so mushroom mushrooms can rapidly grow, and occupy the entire bacterial culture material. Often competed with Pleurotus ostreatus nourishing competitive bacteria such as mold, Penicillium, Mucor, Rhizopus, Aspergillus, Neurospora, etc., in the event of a short period of time they will be a large number of breeding, the expected material and to the internal Spread, compete with the Pleurotus ostreatus nutrition, secretion of toxins, inhibit their growth, resulting in local and even the entire bacterial contamination caused by the cultivation failed. Therefore, raw mushroom cultivation anti-bacterial contamination is a key issue, especially in the cultivation of mushrooms during the hot season.
