Prevent abnormal variation of Lentinus edodes
Lentinus edodes fruiting bodies often appear in the growth process of "candle mushroom", hole handle without cover, snow, "pine mushroom", "litchi mushroom", these are abnormal variation of Lentinus edodes, most of them belong to physiological diseases. In addition to the poor strain or virus infection, the main man-made reasons are: improper selection of ① varieties. For example, medium-and low-temperature bacteria should be selected in high-altitude mountain areas. if high-temperature bacteria are misused, the mushroom buds will shrink and form "pineal mushrooms" when they encounter low temperatures in winter. two
