1987年4月5～16日,我们用香菇8001菌株母种试管分批分期扩接了近1500瓶原种,培养到6月下旬约60天菌龄时,出现了几种不同情况,为了择优弃劣,我们进行了以下试验:(一)试验方法选有代表性的三种类型,将其分成三组:①瓶壁出现分散似豌豆大小的白珠块;②瓶壁无白珠块;③瓶颈处料面有酱色菌皮,但无酱色液珠。三组均按常规接种各20袋,标上记号,置菌种室培养至6月25日止,对以上三组菌袋进行逐个详细考察对比.
April 5, 1987 to April 16, we used the mushroom strains of the 8001 strains of the mother tube in batches staged phase expansion of nearly 1,500 bottles of raw materials to cultivate to the end of June about 60 days of age, there have been several different situations, in order to choose the best Abandoned, we conducted the following tests: (a) test methods were selected representative of the three types, divided into three groups: ① bottle-shaped pearl-like white beads appear dispersed; ② bottle wall without white beads; The bottleneck material surface with sauce color, but no sauce color beads. All groups were routinely inoculated with 20 bags, marked on the sign, bacteria-bearing room until June 25, the three sets of bags carried out a detailed study and comparison.
