玉米粒平菇菌种,具有菌丝萌发早、吃料快、产量高等优点。但一般是以煮熟法制种,手续繁琐,耗能源,且常因水分掌握不当导致污染率高。为此笔者从1990年开始改玉米粒煮熟法为浸泡法制种,获得了满意效果,生产的20000多瓶菌种,成功率达98％以上,质量与煮熟法一样,且抗衰老力增强。现将该法介绍如下: 1 选料浸泡 选无霉变的玉米粒,先用清水浸泡(切勿用石灰水直接浸泡),把漂浮的玉米粒除掉,10小时后捞起改用0.5％的石灰水浸泡,以后每隔20小时换一次0.5％的石灰水。浸泡时间夏季50小时,冬季70小时,以玉米粒吃足水分为宜,捞放筐里用清水冲洗一遍,待无水下滴时即可拌料。 2 拌料装瓶灭菌 将过滤后的玉米粒置水泥地上,先拌入1％石灰粉、1％石膏粉,再加入适量细木屑或细米糠调节湿度,拌匀后装瓶,高压灭菌2小时或常压灭菌 Mushrooms Pleurotus ostreatus, with early mycelium germination, eat fast, high yield advantages. However, the general rule is that the seeds are cooked by law. The procedure is cumbersome and consumes energy, and the pollution rate is often high due to improper water control. For this reason, the author started to change corn kernels into cooked seeds by the method of soaking in 1990, and obtained satisfactory results. The strain of more than 20000 strains was produced with the success rate of more than 98%. The quality was the same as that of the cooked method, and the anti-aging ability was enhanced . The law is introduced as follows: 1 election material soak mildew-free corn kernels, first soaked with water (do not use lime water directly soaked) to remove the floating corn kernels, picked up after 10 hours changed to 0.5% Lime water soak, after every 20 hours for a 0.5% lime water. Summer soaking time 50 hours, 70 hours in winter to eat enough water to eat corn kernels, fishing baskets rinse it again with water until the water drops can be mixed material. 2 Spice sterilization bottles will be filtered corn grain placed on the ground, first mixed with 1% lime powder, 1% gypsum powder, then add appropriate amount of fine wood flour or rice bran to adjust the humidity, mix well after bottling, autoclaving 2 hours or at atmospheric pressure sterilization
