银耳菌种在培养过程极易衰退,会给生产带来一定的损失。怎样防治银耳菌种早衰?我们的经验是:①菌种在移接过程中要尽量少接一些纯白菌丝,以免过多过早地消耗培养基养分。②培养基中要多加5～10%的麸皮或1～2%的黄豆粉,促使菌丝生长强壮。③选择适合银耳生长的木屑,或适当加入甘蔗渣、花生秆粉等,以满足菌丝生长所需 Tremella bacteria in the cultivation process is extremely easy to decline, will bring some loss to production. How to prevent premature failure of fungus? Our experience is: ① strain in the transfer process to minimize the number of access to some pure mycelium, so as not to prematurely consume nutrients in the medium. ② medium to increase 5 to 10% bran or 1 to 2% of soybean meal, prompting mycelium growth strong. ③ choose suitable for the growth of white fungus sawdust, or an appropriate addition of bagasse, peanut stalk powder, etc., to meet the needs of mycelial growth
