笔者在袋栽榆黄蘑生产实践中,摸索出几种不用套环省料、省时、透气性好的封口方法。 1.别针封口:装好料后,将袋口合并对齐,向下折叠1.5cm左右,然后向折叠的一面卷成圆筒,接头重叠2cm左右,用直别针别住重叠处即可。 2.胶布封口:装料至适当部位,压平表面后,料面离袋口的距离约等于袋的直径。先将一面折向对面,再旋转60度折另一面,剩下的一面往回折,然后用胶布粘住接头即可。 3.摆放封口:操作要求同胶布封口法,但不封胶布,只在灭菌时袋口与袋口相对挤紧,接种后培养时,仍将两袋口相对放置。 4.玉米芯封口:适于发酵料开放式接种。边装料边层播菌种,最后袋料中央扎孔,再在穴中补菌种,或装满袋整平料面中央扎孔,往表面和孔里接菌种,将袋
In the bag cultivation of elm mushroom production practice, I explore several do not have collar material saving, time-saving, good ventilation of the sealing method. 1. Pin seal: After loading the material, the bag mouth alignment, fold down 1.5cm or so, and then folded into a cylinder side of the cylinder, the connector overlap 2cm or so, with a straight pin pinch the overlap can be. 2. Tape sealing: loading to the appropriate location, flatten the surface, the material surface distance from the bag is about equal to the diameter of the bag. First side of the fold to the opposite, then rotate the other side of 60 degrees off, the rest of the back to fold, and then glue the joints can be glued. 3. Placing sealing: the operation requirements of the same tape sealing method, but not sealing tape, only in the sterilization of the bag mouth and pocket relative crowded, after inoculation training, the two bags will still be placed relative to each other. 4. Corncob seal: suitable for open fermentation of fermented material. Side of the side loading bacteria, the last bag hole central hole, and then add bacteria in the hole, or fill the bag leveling surface center hole, the surface and the hole in the species, the bag
