菌种的优劣,直接影响到质量和产量,这个问题已引起生产和科研单位的重视。实践证明,选育一个优良菌种固然重要,但保持一个良种的经济性状,同样也是重要的。现将我们对双孢蘑菇菌种冷冻干燥保藏的初步试验结果,报告如下。一、材料及仪器 (一)子实体采集:选生长速度快、粗壮和外形整齐、没有开伞的成熟子实体存放在烧杯中备用。 The merits of bacteria, a direct impact on the quality and yield, this issue has caused the production and research units attention. Practice has proved that breeding a good species is important, but maintaining a good economic traits, is also important. Now we freeze-dried mushroom strains deposited on the preliminary results of the experiment, the report is as follows. First, the material and equipment (A) fruiting bodies collected: choose growth speed, sturdy and neat appearance, there is no open umbrella mature fruiting bodies stored in the beaker.
