辐射处理袋栽香菇培养料不仅能杀菌消毒,而且还能加速香菇菌丝的生长,提高鲜菇产量。这是否与木屑培养料经辐照后,其营养成分发生了变化有关,为弄清这一问题我们对辐照后的木屑培养料主要成分进行了分析测定,以期提供一些科学依据。材料与方法培养料配方为:木屑78%,米糠20%,石膏1%,食糖1%,含水量55%左右。采用1.5万居里农用钴源辐照,辐照剂量分别为1.0、1.2、1.4、1.6和1.8Mrad。每处理重复3次,以高压灭菌作对照。木屑培 Radiation treatment bags mushroom cultivation materials not only sterilization, but also can accelerate the growth of mushroom mycelia and improve mushroom production. Whether this is related to the change of nutrient components after the wood pellets are irradiated, in order to clarify this problem, we analyzed and determined the main components of the wood chips after irradiation, with a view to providing some scientific evidence. Materials and methods The training material formula is: sawdust 78%, rice bran 20%, gypsum 1%, sugar 1%, water content of about 55%. Using 15,000 Curie agricultural cobalt source irradiation, radiation doses were 1.0,1.2,1.4,1.6 and 1.8Mrad. Each treatment was repeated 3 times to autoclave as a control. Sawdust
