在黑木耳生产中,要想得到理想的栽培效果,必须有优良的菌种。菌种在制种过程中,由于保存方法不当没、有及时转接和转接代数过多等因素的影响,常会引起退化。菌种分离是防止菌种退化,获得优良菌种的重要手段。分离黑木耳菌种经常采用的方法有孢子分离法、耳木分离法和子实体组织分离法。 In black fungus production, in order to get the ideal cultivation effect, there must be excellent bacteria. Strain in the seed production process, due to improper preservation methods, timely transfer and transfer of algebra and other factors, often cause degeneration. Isolation of bacteria is to prevent species degradation, an important means of access to good species. Separation of Auricularia species commonly used methods are spore separation, ear separation and fruiting body tissue separation method.
