How to prevent the emergence of screw cap shitake mushroom

The shape of the leechee mushroom is that the mushroom kinks a lot of lychee-like short stipe, non-differentiated vegetative cap, or mushroom cap that only covers the snail. There are many reasons for this malformation mushroom: Some people think that the ratio of carbon and nitrogen in the culture medium is not appropriate; others believe that the genetic character of the strain is not good; we believe that the reason for the malformation mushroom is caused by the low temperature during the mushrooming period. When the fruiting primordia of the medium-temperature or medium-and high-temperature strains of lentinus edodes was differentiated, they suddenly attacked with cold air or cold current, and the cap could not be normally differentiated. Frequently, malformed mushrooms appeared in batches.
Prevention measures are: according to the characteristics of the temperature type of the variety, arrange the inoculation period and the fruiting period; take off the screw cap mushroom, maintain the good mycelia, wait for the temperature, the age of the bacteria and other conditions suitable for mushrooming and then the bud.
