液体菌种具有培养时间短,生长快,发育健壮,便于接种工作的机械化和自动化等优点,但它不耐保存.为了获得金针菇液体菌种合适的保存时间,探索保存时间对菌种活力的影响,以及不同保存方式对保存期的影响,我们于1989年秋对不同保存期和在不同保存条件下的金针菇液体菌种,进行了袋栽出菇对比试验.现将结果报道如下: Liquid strain has the advantages of short cultivation time, fast growth, robust development and mechanization and automation for inoculation work, but it is not resistant to storage.In order to obtain proper storage time of liquid strain of Flammulina velutipes and to explore the influence of storage time on the viability of the strain , As well as the impact of different preservation methods on shelf life, we carried out comparative experiments on the growth of Flammulina velutipes in different storage periods and in different preservation conditions in the autumn of 1989. The results are reported as follows:
