平菇生料栽培,在菌丝生长发育阶段,易出现杂菌(主要是青霉和木霉)污染。因此,控制杂菌污染,是平菇栽培中急待解决的关键问题。在实践中,我们除注意选用优良菌种和新鲜培养料等措施外,也很重视对环境的消毒。试验证明,每立方米空间先用16毫升甲醛和8克高锰酸钾熏蒸24小时,再各喷一次0.2％甲级托布津和1％波尔多液,效果良好,但仍不能杜绝污染。因此,我们又用多菌灵处理培养料,取得了明显效果,现简介
Pleurotus raw material cultivation, mycelium growth and development stage, prone to miscellaneous bacteria (mainly Penicillium and Trichoderma) contamination. Therefore, the control of bacterial contamination, mushroom cultivation is an urgent solution to the key issues. In practice, we not only pay attention to the selection of fine strains and fresh culture materials and other measures, we also attach great importance to the disinfection of the environment. The test proves that fumigation with 16 ml of formaldehyde and 8 g of potassium permanganate first for 24 hours per cubic meter of space and then sprayed with 0.2% class A Topaz and 1% Bordeaux mixture each have a good effect, but still can not eliminate the pollution. Therefore, we also use the carbendazim treatment of culture materials, achieved remarkable results, is now profile
