本研究,以严重危害双孢蘑菇(Agaricus bisporus)栽培业的蘑菇粉孢霉(Oidiumagaricus)为试验材料,进行了分离、纯培养、生物学特性观察;并通过病害防治试验,筛选出了有效的药剂。主要结果如下:(1)在无菌条件下,从覆土中分离获得粉孢霉纯菌种,经鉴定,该菌属于半知菌类(Fungi Imperfecti)丛梗孢目(Moniliales)丛梗孢科(Moniliaceae)粉孢霉属(Oidium)蘑菇粉孢霉(Oidium agaricus);(2)该菌主要在畜粪中孳生,菇床发生时可分为初发期、盛发期、衰亡期三个阶段,最适生长条件为:温度20±1℃,pH7.0,培养料含水量60—70％;(3)1:500—800倍50％可湿性多菌灵对该杂菌有良好的防治效果。增产35％左右。
In this study, Oidiumagaricus was severely endangered the cultivation of Agaricus bisporus, and its isolation, pure culture and biological characteristics were observed. Through the disease prevention and control test, the screening of effective Pharmacy. The main results are as follows: (1) Under pure conditions, the pure strain of Aspergillus candidora isolated from the soil cover, the strain was identified as Fungi Imperfecti (Moniliales) (Oidium agaricus) of Moniliaceae (Moniliaceae); (2) the bacteria mainly breed in livestock excrement; the occurrence of mushroom bed can be divided into initial stage, vigorous stage and decay stage Stage, the optimum growth conditions are: temperature 20 ± 1 ℃, pH7.0, water content of culture medium 60-70%; (3) 1: 500-800 times 50% wet carbendazim on the bacteria have a good Control effect. Increase about 35%.
