我县从1988年开始试生产蘑菇生粪种,效果很好。它既解决了粪草种的某些不足,又克服了麦粒种制种成本高,厂家风险性大,播种后易遭鼠害等缺点,深受菌种厂家和菇农的欢迎。1991年我县蔗地种菇用此菌种就达15万瓶,现将菌种的制作技术及应用介绍如下: 主料是干牛粪粉86％,麦壳或谷壳10％、石膏粉2％、过磷酸钙1％、生石灰粉1％。牛粪晒干打细过筛(1厘米眼)或用粉碎机粉碎,若过筛处理,应提前24小时预湿。麦壳或谷壳选新鲜无霉变的,用前在2％的石灰水中软化5—8小时。拌料时,为防止牛粪粉飞扬,可先用适量的水预湿,再加入其它辅料拌匀。制种前期或含水量控制在55—60％,中后期控制在60—65％,扑料时pH值保持在9左右。装瓶做到上紧下松,外紧内松,料装至瓶肩,洞一定要打到底,以增 My county since 1988, the trial production of mushroom raw manure species, the effect is very good. It not only solves some problems of dung grass species but also overcomes the shortcomings of high seed cost of wheat seed production, high risk of manufacturers and susceptibility to rodent infestation after sowing, and is widely welcomed by the strain manufacturers and mushroom farmers. In 1991 the county of sugarcane planting mushrooms up to 150,000 bottles, now the production technology and application of strains are as follows: Ingredients are dry cow dung powder 86%, 10% wheat husk or chaff, gypsum powder 2%, superphosphate 1%, quicklime 1%. Cow dung dried carefully sift (1 cm eye) or crushed with a crusher, if sieved, it should be pre-wet 24 hours in advance. Wheat germ or chaff choose fresh mildew, before use in 2% lime water to soften 5-8 hours. Mixing materials, in order to prevent dung powder flying, pre-wet with an appropriate amount of water, then add other accessories mix well. Pre-seed production or water content control in 55-60%, control in the late 60-65%, when the pH value of the material remained at 9 or so.
