用稻草栽培平菇,为预防霉菌污染,一般都需先用石灰水浸泡处理.然后再用清水冲至pH7.5～8.5才能下种.这种方法不仅操作麻烦,且霉菌污染仍时有发生.根据石灰水碱性的不稳定性和生料栽培中微生物发酵会产酸的特点.笔者试验发现稻草用2～4%的石灰水浸泡后.不必用清水冲洗直接下种,平菇菌丝能正常萌发吃料,且霉菌污染率低,出菇正常.具体做法是:选择干燥无霉变的青白稻草,用2～4%的石灰水浸泡1～2天,待稻草表面蜡质去除,用手触之感觉柔软,捞起堆成堆,让其水分流失至握之手指缝间有水印出即可下种.采用层播法,分两层下 Mushroom cultivation with straw, in order to prevent mold contamination, generally need to be soaked with lime water treatment and then rinse with water until pH7.5 ~ 8.5 under the species .This method is not only the operation of trouble, and mold contamination still occur .According to the instability of alkaline lime water and raw materials in the fermentation of microbial fermentation will produce acid characteristics.I found that straw with 2 to 4% lime water after soaking.No need to rinse with water directly under the species, mushroom Can normally germinate eat material, and low mold pollution rate, fruiting normal.The specific method is: Select dry and moldy green white straw, with 2 to 4% of limewater soak for 1 to 2 days until the straw surface wax removal, Feel soft by hand, picked up a pile of piles, so that the loss of water to the fingers of the hands of the water seal can be planted under the species. Using stratification method, sub-two-story
