制好菌种是取得木屑栽培香菇成功的基础,原种和栽培种是生产的关键。原种质量的好坏,直接影响到栽培种的成品率以及栽培产量。制原种时力求做到以下几点:(1)仔细检查发菌情况,随时掌握菌丝生长动态,对菌丝生长异常的菌种,如菌丝吃料慢,发菌参差不齐,菌丝浓淡、粗细不一致,甚至出现拮抗现象的要拣出来,不能使用。(2)保证恰当的菌龄,一般采用菌丝刚发到瓶底的原种,因为这种菌丝年 Making good bacteria species is the basis for the success of sawdust cultivation of mushrooms, the original species and cultivars is the key to the production. The quality of the original species, a direct impact on the yield of cultivated species and the cultivation yield. When the original species system to achieve the following points: (1) carefully check the germs, keep abreast of mycelial growth dynamics, abnormal growth of mycelium species, such as hyphae slow feed, germs uneven, bacteria Silk shades, inconsistent thickness, and even antagonistic phenomena to be picked out, can not be used. (2) to ensure the proper age of bacteria, the general use of mycelium just sent to the bottom of the original species, because of mycelial year
