草菇属于高温型担子菌,其菌丝生长最低温度为15℃。菌种一般须在15～20℃恒温下保存越冬,条件要求高,投资也大。笔者经过两年的试验,摸索了一套简单经济的草菇菌种越冬保存方法,现简报如下:(一)保存种的培养供试菌种为 V_(21)、V_(?),引自华中农大。培养基配方为棉子壳80%,麸皮10%,过磷酸钙2%,石灰4%,石膏2%,糖2%,含水量65%
Straw mushroom is a high temperature basidiomycete, the mycelium growth minimum temperature of 15 ℃. Species must be stored at 15 ~ 20 ℃ constant temperature winter, high conditions, investment is also large. After two years of experiments, the author explored a set of simple and economical methods of overgrowth preservation of mushroom strains. The briefing is as follows: (1) The cultivated species of the preserved species are V_ (21), V_ (?), Huazhongnongda. The medium formula is 80% of cotton seed shell, 10% of bran, 2% of superphosphate, 4% of lime, 2% of gypsum, 2% of sugar and 65% of water content.
