在食用菌制种和栽培中,为了预防杂菌(特别是木霉)的污染,许多栽培者常在培养料中加些杀菌剂,由此而引出了用药安全性等问题。对于这种情况,我们选择了高效低毒的托布津和多菌灵两种常用杀菌剂,观察了它们对几种常见食用菌菌丝生长和出菇的影响,力求找到合适的用药浓度。现将初步结果报道如下: In the edible fungus breeding and cultivation, in order to prevent the contamination of bacteria (especially Trichoderma), many growers often add some fungicides in the culture medium, which leads to drug safety and other issues. In this case, we chose two kinds of commonly used fungicides: Topazin and Carbendazim, which are efficient and low-toxic. We observed their effects on mycelial growth and fruiting of several common edible fungi, and tried to find a suitable drug concentration. The preliminary results are reported as follows:
