谷子粒作培养基,比棉籽皮或木屑作培养基,菌丝比满瓶的时间短、转接袋数多,菌种分散性好,成本低。河北省食用菌研究所谷子粒菌种在金针菇、平菇、香菇、灰树花等食用菌生产上取得了成功。(一)制作方法1.配方。谷子粒90%,棉籽皮8%,石膏1%,石灰1%,含水量45%。2.预煮。称好谷子粒放入锅中加水,超过谷子粒4-5厘米为宜,开锅后再煮8分钟左右。此时谷子粒已充分吸水而未破肚,这是预煮的最佳程度,然后把谷子粒捞出,控出水放于大盆中。煮好的谷子粒含水量约45%。3.装瓶。把石灰、石膏直接加入煮好的谷子粒中,棉籽皮需经预湿(含水量同常规培养基)。将几种原料充分拌匀。谷子粒菌种瓶应选用750毫升菌种瓶或500毫米的酒瓶。谷子粒装到瓶子的一半或稍多一些,不宜过多。750毫升菌种瓶装100克干料,白酒瓶装80克干料。瓶口用湿布清理干净,塞上棉塞,棉塞要松紧合适,棉塞外面再用一层牛皮纸包住。4.灭菌,摇、接种。灭菌时间比常规培养基稍长 Millet grains for the medium, cottonseed or wood as a medium, mycelium than the full bottle of time, transfer bags and more bacteria good dispersion, low cost. Hebei Institute of Edible Fungi Valley grains in mushrooms, mushrooms, mushrooms, grifola and other mushroom production success. (A) production methods 1 formula. 90% of grain of grain, 8% of cotton seed coat, 1% of gypsum, 1% of lime and 45% of water content. Pre-cook Weigh good grain of grain into the pot of water, more than grain 4-5 cm is appropriate, boil and cook for about 8 minutes. At this point grains have been fully absorbed water without broken belly, which is the best pre-cooked, and then remove the grain of grain, control the water put in a large basin. Cooked grain of corn water content of about 45%. 3. Bottling. The lime, gypsum directly into the boiled grain, cottonseed skin need to be pre-wet (water with the conventional medium). Several ingredients will be fully mixed. Valley grains should be used 750ml strains bottle or 500mm bottle. Millet tablets loaded into the bottle half or slightly more, not too much. 750 ml of bacteria bottled 100 grams of dry material, 80 grams of white wine bottled dry material. Clean the bottle mouth with a damp cloth, tampon plug, tampon to be tight, tampons and then covered with a layer of kraft paper. Sterilization, shaking, vaccination. Sterilization time slightly longer than conventional medium
