代料栽培香菇,接种时值一年中气温最高的8月,接种稍不小心就会“病从口入”,遭至杂菌感染,从而影响经济效益.针对这个问题,我们对封口材料进行了研制和试验.(一)供试材料:香菇菌袋按常规要求制作灭菌,封口材料是①对照组为食用菌专用胶布;②试验组为封口剂,配方是石蜡(或矿蜡)4份、石膏4份、菜籽油2份、松香0.5份,制作时先将松香粉碎,再将石蜡、松香和菜油置搪瓷杯或烧杯中加热至熔化,然后加入石膏搅拌后继续加热至沸腾即可.使用时温度要保持在60～70℃.
Substitute for the cultivation of mushrooms, when the inoculation value of the highest temperature in a year in August, inoculation is a little careless “disease from the mouth,” suffered by bacteria infection, thus affecting the economic benefits.In response to this problem, we sealed material The test materials: mushroom bag according to the normal requirements of the production of sterilization, sealing material is ① control group for edible tape; ② test group as sealing agent, the formulation is paraffin (or wax) 4 , 4 parts of gypsum, 2 parts of rapeseed oil and 0.5 parts of rosin. The rosin is firstly smashed and then the paraffin, rosin and vegetable oil are melted in an enamel cup or a beaker, and then the gypsum is stirred and then heated to boiling Can be used when the temperature to be maintained at 60 ~ 70 ℃.
