利用资源丰富的禾谷类茎秆栽培木耳,可以部分地解决生产上的原料问题。经我们多次试验,证明仅用高粱秆可以取代棉于壳及木屑栽培木耳,其生产周期比木屑短,生物效率可达到130％～150％。现将其栽培技术报告如下。 (一)栽培时间 在11月至次年3月培养菌丝体,在此季节菌丝生长虽慢,但污染少。5月初～7月雨水充足,湿度大,气温高,符合木耳喜温、爱湿的要求,此时催耳可以达到优质高产的目的。 (二)备料装袋 经试验各种类型的高粱秆、叶均可使用,一般去掉穗部和根,充分晒干备用。①将充分晒干无霉变的高粱秆(带叶),截成3～4cm长,用水浸泡使之吸足水分,而后捞出晾干表面水分装袋,边装边振摇,以达到自然紧度。②将高粱秆截成比所采用的料袋短1/5～1/4,而后用塑料钱捆成比料袋稍小的小捆,以能装进袋为佳,而后向袋中灌水,待料吸足水分后,倾去多余水,用牛皮纸包口以备灭菌。 (三)灭菌接种 将装好的料筒移入高压锅,121℃灭菌45分钟,而后按无菌操作接种。菌种选用湖南常 The use of resource-rich cereal stems for fungus cultivation can partially solve the problem of raw materials for production. After many trials, we proved that sorghum stalks can replace cotton fungus and fungus to grow fungus. The production cycle is shorter than sawdust, and biological efficiency can reach 130% -150%. Now its cultivation techniques are as follows. (A) Cultivation time Cultivation of mycelium from November to March next year, mycelium growth in this season is slow, but less pollution. Early May ~ July adequate rainfall, humidity, high temperature, in line with the fungus hi temperature, love the wet requirements, this time the ear can achieve the purpose of high quality and high yield. (B) preparation Bagging After testing various types of sorghum stalks, leaves can be used, generally remove the ears and roots, fully dried spare. ① will be fully dried mildew-free sorghum stalk (with leaves), cut into 3 ~ 4cm long, soaked in water so that suction enough water, and then remove and dry the surface of the water bagging, while mounted shake side to achieve natural Tightness. ② The sorghum stalk cut shorter than the material used in the bag 1/5 to 1/4, and then bundled with plastic money slightly smaller than the bag of small bundles, to be able to put into the bag is better, and then to the bag irrigation, Suction enough to absorb enough water, dump excess water, with kraft paper mouth for sterilization. (C) Sterilization Inoculation will move the barrel installed into the autoclave, sterilized at 121 ℃ for 45 minutes, and then vaccinated by aseptic technique. Hunan bacteria often used
