在代料栽培滑菇的发菌后期,料面上出现一层光滑、具光泽、有韧性、红褐色或褐色的角质化膜,我省菇农称它为蜡层或蜡质层。笔者经几年的观察和试验,现就蜡层形成同菌丝生长、环境条件的关系和蜡层在栽培上的作用及其控制方法作一简介。(一)蜡层与菌丝长势的关系蜡层是菌丝经充分交织后,在交织物周围出现的白或浅白色的液体逐渐变硬而成。其液体是由菌丝细胞所分泌,因此在滑菇的发菌阶段,菌丝生长越旺盛,细胞代谢所分泌的液体也越多,生成的蜡层也就越厚。在一般情况下,蜡层的厚为5～10mm,有的达15～20mm。反则,如 In the later stage of fungus-feeding fungi, the material surface appears a smooth, shiny, toughness, reddish-brown or brown keratinized film, mushroom industry in our province called wax layer or wax layer. The author after several years of observation and experiment, now the formation of the wax layer with mycelial growth, the relationship between environmental conditions and the role of wax layer in the cultivation and control methods for a brief introduction. (A) the relationship between wax layer and the growth of mycelium wax layer is mycelium fully interwoven, the white or light white liquid around the fabric gradually hardened. The liquid is secreted by the mycelial cells, so in the fungus stage of fungus mushroom growth, the more vigorous growth of cells, the more liquid secretion of the cell metabolism, the thicker the resulting wax layer. Under normal circumstances, the wax layer thickness of 5 ~ 10mm, some up to 15 ~ 20mm. The contrary, such as
