Introduction to the specific method of soil-covering cultivation of shiitake mushrooms
First, soil-covering 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 fruiting bodies large, the flesh thick, and the number of flower shiitake abundant. Second, compared with the conventional method, the yield can be increased by 30%-40%. Third, after the substrate sticks are removed from the bags and covered with soil, they can change color naturally and are not easily infected. Fourth, after the substrate sticks are covered with soil, they can fully utilize and absorb the water and nutrients in the soil, which can save the cumbersome procedure of soaking the substrate sticks to replenish water after each flush of mushrooms. The specific method is as follows: bed width 80-100 cm, depth 20 cm
