茯苓纯菌种栽培法,可以节约苓块,减少污染,提高段木菌丝的成活率,增加产量。一般采用菌核组织分离和孢子分离两种方法。纯菌种菌核组织分离法简便易行,但菌种易退化。例如,我厂在1978年用这两种分离法获得的菌株,第二年在同样的条件下进行扩大栽培种时,用菌核分离得到的菌丝当年生长良好,次年瓶底处出现黄水,产生退化,而孢子分离的菌丝仍然洁白粗壮,生活力旺盛,放置2～5个月,也未变棕色及出水。 1979年,我们在龙溪县采集了两个菌核,重量分别为17、18斤。采集的菌核置于塑料袋中保湿运回,分离孢子,进行制种。
Poria pure cultivation method, you can save Ling block, reduce pollution and improve the survival rate of Duanmu mycelia and increase production. Generally used two methods of sclerotia and spore separation. Pure bacteria sclerotia separation method is simple and easy, but the strain is easy to degenerate. For example, when the strain obtained by the two isolation methods in our factory in 1978 was expanded under the same conditions the following year, the mycelium isolated from the sclerotia grew well in that year and the yellow Water, produce degradation, and spores isolated mycelium is still white stout, strong vitality, place 2 to 5 months, nor change brown and water. In 1979, we collected two sclerotia in Longxi County, weighing 17 and 18 catties respectively. The collected sclerotia is placed in a plastic bag, moistened and transported back to separate the spores for seed production.
