云南玉溪地区农科所科技人员为有效防治食用菌生产中竞争性杂菌连续污染,采用不同石灰用量(～20％)防治试验表明,石灰用量达20％的培养基上,菌丝照样能正常生长,不同的石灰用量对菌丝生长速度也无明显的影响,且随着石灰用量的增加,杂菌污 In order to effectively control the continuous contamination of competitive bacteria in the production of edible fungi, the scientific and technological personnel of Yuxi Prefecture Agricultural Science Institute conducted experiments on the prevention and control of different lime contents (~ 20%), indicating that mycelium can still be normal on the medium with the dosage of lime up to 20% Growth, different amount of lime on the growth rate of mycelium also had no significant impact, and with the increase of lime dosage,
