草菇要稳产高产极为困难,其主要原因是草菇不容易出菇、出菇不齐、鬼伞多。 一、不出菇的原因 1.菌种传代过多。良种以不超过三代为宜,一年提纯复壮一次;2.菌龄过长。菌种以刚长好为宜;3.培养料含水量低(以65％—70％为好),使已形成的菌蕾萎缩,未形成的不能形成;4.平均气温23℃以下,或40℃以上,子实体难 Straw mushrooms to high-yielding stable yield is extremely difficult, the main reason is that straw mushroom is not easy to fruiting, fruiting missing, more than a ghost umbrella. First, the reasons for not mushroom 1. Bacterial passage too much. Seed no more than three generations is appropriate, a year purification and rejuvenation; The strain grows well is appropriate; 3 culture material moisture content is low (65% -70% is good), so that the formation of a bacterial bud atrophy, not formed can not form; 4 average temperature below 23 ℃, or 40 ℃ above, fruiting bodies difficult
