How to choose wood varity & wood chips size for shiitake production?

To make shiitake mushroom, usually use pure oak chips. Oak wood is hard and rich in lignin. The shiitake grown are larger in size and thicker in meat.

even oak wood with the same name, the climatic conditions in different regions are different, and the content of lignin will also be different. that'

s why The quality and purity of oak wood must be guaranteed.

The oak wood in deep mountains is processed into chips, and then made into shiitake logs after filling into bags. After 120 days of constant temperature cultivation in a constant temperature culture room, shiitake will fruit.

For the same pure oak chips, is there any difference in the size of wood chips?

Why do spring-planted shiitaek in Biyang generally use large wood chips, while autumn-planted shiitake or shiitake logs made in factories generally use small wood chips?

1.Large wood chips's lignin takes a long time to decompose, the nutrients are released slowly, with strong fruiting power in later stage, so it is more suitable for long-aged mushroom varieties Or in areas where shiitake logs need pass summer and have long cultivation period and long fruiting period

2. Large chips has good air permeability, mycelium grows more vigorously, mycelium color is whiter, and it is easier to form nodules.

3. Large chips can store more water, the shiitake log bag is heavier, and the shiitaek are more vigorous in the later fruiting stage.

4. Large chips is generally not easy to burst shiitake, and the shiitaek grown are large and thick, not easy to open the umbrella.

One disadvantage for large chips is that there may be many micropores when bagging, so the chips should be pre-wetted and softened in advance, and the pile should be turned.

Tips: The shiitake in Biyang generally use large wood chips,

as Biyang shiitake substrate are generally filled into bags before and after Chinese New Year, they have to survive the summer in the middle, and start fruiting in autumn, and continue fruiting until spring of the second year. The cultivation cycle and fruiting cycle are very long, and the nutrients in the shiitake bags can be fully released, so that not only the shiitake yield is high, but also the quality is good.
