2.菌筒转色及异常现象的处理脱袋排场后的菌筒,由于全面接触空气、光照和菌筒内营养成分的变化,以及露地湿度等因素的影响,便从营养生长转为生殖生长。菌筒表面逐渐长出一层浓白色绒毛状的菌丝,接着倒伏形成薄的菌膜,同时开始分泌色素。开头白色略转粉红色,逐步变为棕褐色,最后形成一层似树皮状的褐色菌膜,这就是所说的菌筒转色,也就是“人造菇木”的形成。这种转色,通常在脱袋后,适宜的环境条件下,需要12天左右结束,若气温低还得拖延3～5天。 A.菌筒转色期的管理:菌丝转色的深浅,菌膜厚薄,直接影响着香菇的产量和品质。转色适宜,菌筒表面形成一层棕褐色、
2. Discoloration of the fungus barrel and disposal of the abnormal phenomenon The fungus barrel discharged from the pouch after pouch discharge is changed from vegetative growth to reproductive growth due to the changes of nutrients in the air, light and fungus barrel as well as the humidity in the open field . Gradually grow a layer of fungus tube thick white fluffy mycelium, and then lodging to form a thin film of bacteria, and began to secrete pigment. The beginning of a little white light pink, and gradually turned brown, and finally form a layer of bark-like brown film, which is the tube color, that is, “mushrooms wood” formation. This color change, usually in the bag, the appropriate environmental conditions, it takes 12 days or so, if the temperature has to delay 3 to 5 days. A. tube barrel color management: the color of mycelium to color, film thickness, a direct impact on the yield and quality of mushrooms. Color suitable, bacteria tube surface to form a layer of tan,
