Detailed Explanation of Key Points of Bag-Cultivated Shiitake Mushroom Cultivation Techniques

Shiitake mushroom is a type of mushroom that many people love to eat, and there are many different cultivation methods, so what are the bag-cultivated shiitake mushroom cultivation techniques? Let's take a look.

1. Temperature

The growth temperature range for bag-cultivated shiitake mushrooms is 5-32°C, and the temperature also needs to be adjusted appropriately at different growth stages.

Generally speaking, the temperature range for shiitake mushroom mycelium growth is 5-32°C, with the optimum temperature being 24-27°C. Growth is poor below 10°C and above 32°C, stops above 35°C, and the mycelium dies quickly above 38°C. Within the low temperature range, mycelium grows slowly; from 15°C onward, mycelium growth accelerates as the temperature rises; after 28°C, mycelium growth rate drops rapidly; and at 30-35°C it stops growing.

Shiitake mushroom primordia differentiate at 8-21°C, with the best differentiation at 10-12°C. The fruiting bodies develop within the range of 5-24°C, with 10-20°C being the fastest and most suitable for development.

2. Seed Selection

Choose suitable mushroom spawn, cultivate shiitake mushrooms in suitable climate and season, and prepare suitable growing substrate before cultivation.

When cultivating, choose different mushroom spawn according to your own needs, combined with local conditions and climate.

Observed with the naked eye, mushroom spawn with white mycelium, vigorous, plump, dense, uniform, and spreading growth, without inhibition lines, without shriveling, and without is better mushroom spawn.

In addition, the growing substrate suitable for shiitake mushroom growth also has main materials and auxiliary materials. Broadleaf tree sawdust is the main material. Except for paulownia and poplar sawdust, which have poor nutrition, other broadleaf tree sawdust are high-quality main materials for cultivating shiitake mushrooms, with hard wood species such as Castanopsis, Quercus glauca, oak, maple, and birch being the best.

Auxiliary materials such as wheat bran and rice bran are used in larger amounts, and are required to be fresh, without mold or insect damage. Gypsum powder and white sugar are auxiliary materials used in smaller amounts, and the finer the gypsum powder, the better.

3. Other Management

During the growth period of bag-cultivated shiitake mushrooms, management of factors such as temperature and humidity must also be done well.

Attention must also be paid to pH, and the pH suitable for shiitake mushroom mycelium growth is between 4.5-6.
