北京市地下防空洞面积大,利用率不高,如果用来种植平菇,对改善人民生活,安置待业青年,是一条好门路。我们在实地调查防空洞的温度、湿度、通风等条件的基础上,于80年9月在宣武区的防空洞进行了棉籽皮箱栽平菇试验,取得较好的效果。现就几个主要问题归纳如下: 1.减少杂菌的污染问题。将棉籽皮暴晒2～3天,可起到初步消毒作用。操作室、容器和接种工具要用新洁尔灭清洗,用甲醛或硫磺薰蒸。接种前菌种瓶口应用新洁尔灭液(0.5％)擦洗,并在酒精灯火焰旁打开瓶口包扎物。如用木箱,最好选松木(硬杂木易长青
The underground shelter in Beijing is large in area and its utilization rate is not high. If it is used for planting Pleurotus ostreatus, it is a good way to improve people’s life and place unemployed youth. On the basis of field investigation of the conditions of air-raid shelter such as temperature, humidity and ventilation, we carried out the test of transplanting mushrooms with cottonseed bin in the air-raid shelter of Xuanwu District in September of 1980 and achieved good results. Now summarize several major issues are as follows: 1. To reduce the problem of contamination of bacteria. Cottonseed skin exposure 2 to 3 days, can play a preliminary disinfection. Operation rooms, containers and vaccination tools should be cleaned with benzalkonium bromide and fumigated with formaldehyde or sulfur. Before inoculation, the bottle should be cleaned with benzalkonium bromide (0.5%) and the bottle dressing should be opened next to the alcohol lamp flame. If the wooden box, the best choice of pine (hardwood easy to Evergreen
