白金针菇工厂化生产工艺研究

Commercial production of Flammulina velutipes

采用白金针菇8903菌株进行工厂化袋栽生产工艺试验。结果表明：白金针菇对未处理的木屑的消化吸收能力差，菌丝培养中后期易吐黄水，原基偏黄，推迟开袋5～7d，菇体基部淡黄，产量低，品质差；新鲜蔗渣营养丰富，子实体产量质量均优于长期露天堆放蔗渣；菌包料高14cm可满足营养需求；光照（40W日光灯）20～24h可提高平整度，又可增产和提高品质；白金针菇对黄色光较敏感，绿色光次之，而对红色光则不敏感，以黄色光诱导效果佳。

Flammulina velutipes strain 8903 was used in the evaluation of the commercialization of the mushroom＇s bag--cultivation and processing. The results showed that F. velutipes was poor in utilizing the nutrients in untreated sawdust, its hypha tended to produce yellow exudate, its stipes turned straw-yellow in color, the bag opening was 5--7 days later than the control, its fruit body radicle was straw-yellow in color, had low yield and poor quality. On the other hand, the fresh bagasse was rich in nutrients and could produce F. velutipes fruit bodies with higher yield and better quality than the bagasse, which had been stacked outdoor for a long time. The 14cm-height composting in the fungus bag （17.5 cm）〈 38 cm ）〈 0. 055 cm） was sufficient for F. velutipes＇ nutritional requirement. Illumination （40w florescent lamp） for 20-24 h improved the shape, yield and quality of the mushroom. F. velutipes was more sensitive to yellow light followed by green light, but not to red light. Thus, yellow light induction would produce the best effects compared to other light.
