草菇是一种高温高湿型伞菌,生长迅速。播种后经5～6天,料面出现许多“芝麻”状大小的菌蕾,再隔3～4天就能形成肥厚的子实体。但在生产中经常遇到菌蕾萎缩或死菇,给菇农造成了损失。菌蕾萎缩和死亡的原因和防治措施简述如下: (一)菌种老化、退化由于母种试管分离次数过频,菌龄过长,菌种老化,播种后菌丝生长缓慢,萌发、吃料、封面困难,导致分解和同化有机物的能力下降,影响菌丝养分的积累,阻碍了菌蕾生长。为此,菌种必须年年分离或引进新种,适温保存;栽培种菌龄掌握在25天左右。
Straw mushroom is a high temperature and humidity type toadstools, growing rapidly. After sowing by 5 to 6 days, the material surface there are many “sesamia” -like bacteria buds, and then 3 to 4 days to form a hypertrophic fruiting body. However, in production often encounter bacterial spore atrophy or dead mushroom, mushroom farmers caused losses. Cause and control measures for bacterial atrophy and death are summarized as follows: (A) strain aging, degradation As the mother of the tube frequency of over-separation, bacteria age is too long, strain aging, mycelial growth slow, germination, eating Materials, cover difficulties, leading to the ability to decompose and assimilate organic matter decreased, affecting the accumulation of mycelium nutrients, hinder the growth of bacteria buds. To this end, species must be separated every year or the introduction of new species, suitable temperature preservation; culture species age control in about 25 days.
