为了缩短栽培周期,节省灭菌费用,我们于1987～1989年,试验用半生料栽培香菇,收到了理想的效果,现简报如下:(一)供试材料菌株为香菇856,引自福建古田。培养料配方为木屑68%、谷壳10%、食糖1%、米糠19.6%、石膏1%、多菌灵0.4%,pH7.5～8。其它材料有塑料薄膜、压块木框、塑料袋、高锰酸钾等消毒药品和工具。(二)试验方法所谓半生料栽培,就是指用种量大于料干重的15%的生料栽培方法。我们在栽培时用种量控制在20～35%。培养料拌匀后,先把经消毒的塑料薄膜铺在地上,再将木框(31×24×6cm)置薄膜上。撒一层香菇栽培种于框内,四角多放些菌种,然后铺3cm 厚培养料,再撒一层菌种,如此反复,直至木框装满压实后,最后用菌种封面,压平脱框后用薄膜覆盖保温保湿。
In order to shorten the cultivation period and save the cost of sterilization, in 1987 ~ 1989, we tested the cultivation of mushrooms with half-raw material and received the ideal results. The briefing is as follows: (1) The tested material was mushroom 856, which was introduced from Gutian, Fujian. Cultivation materials for the 68% sawdust, chaff 10%, sugar 1%, rice bran 19.6%, 1% gypsum, carbendazim 0.4%, pH7.5 ~ 8. Other materials are plastic film, briquetting wooden frame, plastic bags, potassium permanganate and other disinfectants and tools. (B) test method The so-called half-raw material cultivation, refers to the use of more than 15% of the material dry weight of raw material cultivation methods. We use the amount of control in the cultivation of 20 to 35%. Cultivation mix well, the first disinfect the plastic film on the ground, and then wooden frame (31 × 24 × 6cm) set the film. Sprinkle a layer of mushroom cultivation in the box, putting more bacteria in the corners, and then shop 3cm thick culture material, and then sprinkle a layer of bacteria, so repeatedly until the wooden frame full of compaction, and finally with bacteria cover, pressure Flat off the box after the film covered with insulation moisturizing.
