Detailed Explanation of Key Points of the Buried-Casing Cultivation Technique for Shiitake Mushrooms

Mushroom Cultivation 0 views
First, the buried-casing cultivation of shiitake mushrooms adopts techniques such as natural color change, open fruiting, widening the wet-dry difference, and water management with alternating wet and dry conditions, which can make the shiitake mushrooms large in body, thick in flesh, and abundant in flower shiitake. Second, compared with the conventional method, the yield can be increased by 30%-40%. Third, after the substrate logs are removed from the bags and covered with soil, they can change color naturally and are not easily infected. Fourth, after the substrate logs are covered with soil, they can fully utilize and absorb the moisture and nutrients in the soil, which can save the cumbersome process of soaking the substrate logs to replenish water after each flush of mushrooms. The specific method is as follows: bed width 80-100 cm, depth 20 cm, length unlimited,

The specific method is as follows: bed width 80-100 cm, depth 20 cm, length unlimited. For each kilogram of the soil used for casing, mix 1.25 g of 80% dichlorvos emulsifiable concentrate, 10 g of 50% phoxim emulsifiable concentrate, 1.7 g of potassium permanganate, and 5 g of formaldehyde, spray once, cover with plastic film, and fumigate in a sealed manner for 24 hours to kill insects and sterilize before use. Remove the bags from the substrate logs whose mycelium has reached physiological maturity, lay them flat close together in the bed, cover with soil, then cover with wheat (rice) straw and spray wet. After 7-10 days, remove the surface casing soil to expose the surface of the substrate logs, water once heavily, and thereafter adopt water management with alternating wet and dry conditions. After a large number of mushroom buds form, water once heavily again so that the soil layer absorbs water thoroughly, and do not spray water thereafter. After harvesting one flush of mushrooms, turn the substrate logs over, cover with soil again, and manage according to the above method.
