The Latest Artificial Cultivation Techniques and Methods Tutorial for Hypsizygus marmoreus

Hypsizygus marmoreus, also known as the brown beech mushroom, is a wood-rotting fungus that mainly grows in temperate regions, and in the wild it mostly grows on trees in autumn. At present, the main cultivated varieties are the gray type and the white type, and the white type is very popular. It was initially Japan that successfully developed the cultivated variety, and afterward it was gradually promoted and popularized. Today's article is mainly about explaining the detailed artificial cultivation methods for this Hypsizygus marmoreus, to help friends who want to learn about it.

1. Cultivation site

Use housing, warehouses, and basements as the cultivation site, requiring the characteristics of being dry, clean, heat-retaining, and well-ventilated. Places with large day-night temperature differences are not suitable for cultivation, such as plastic greenhouses. During the fruiting period, in order to keep warm, generally in the south a thatched shed must be built, and in the north cultivation is done in trench sheds, all for the purpose of keeping warm.

2. Making the culture medium

Use sawdust, cottonseed hulls, corn flour, wheat bran, calcium sulfate, and lime to prepare it together. The prepared culture material must be steamed and sterilized before being put into bottles; for bagging, it should be stacked together when bagging and steamed with a steam machine. The amount of material loaded must be consistent, not more for some and less for others. After bottling, the lids must be quickly capped; for bagging, the bag openings must be tied tightly beforehand.

3. Inoculation

Before inoculation, first check whether the spawn has contaminating bacteria. After the spawn has grown all over the bottle and the mycelial cross-section appears beige, that is the sign of maturity, and then inoculation can be carried out. Inoculation must be carried out in a fully sterile inoculation room. The inoculation bottles must be disinfected and treated, the workers must wear clean work clothes, the hands must be wiped with alcohol, all tools must be disinfected multiple times, and the entire inoculation work surface must be disinfected.

4. Promoting growth

The mycelium grows fastest at 22 to 25 degrees, which will cause the temperature inside the mycelium bottles to exceed the outside, so the temperature should be lowered to 20 to 22 degrees. Rapid growth produces a large amount of carbon dioxide, so a heat-exchange ventilation device should be used indoors to reduce the indoor carbon dioxide content. Growth needs to be kept in a dark state, otherwise mushroom buds are easily produced. After inoculation and growing all over the bottle, cultivate for another two months, and the moisture must be kept above 70%.

5. Mushroom growth

The fruiting bodies can grow at 8 to 22 degrees, and a certain temperature difference can promote rapid growth. The most suitable temperature for growth is 12 to 18 degrees. Below 8 degrees, or above 22 degrees, growth is difficult. If it is a mushroom growing out from the top, it can grow slowly below 25 degrees. Low temperatures tend to make the mushroom base thick and sturdy, while high temperatures tend to make the stems long. During the mushroom bud stage, the humidity is above 85%; in the later stage, the humidity should be lowered. Long periods of high humidity easily cause bitterness and disease. In the middle of the mushroom bud stage, 7 to 10 hours of light are needed; in the later stage, 15 hours of light per day are needed, with the lights turned on at night.

The preparatory work for cultivating Hypsizygus marmoreus is choosing the site, making the culture medium, and inoculation. The most important part is the later fruiting management, at which time there are certain requirements for temperature, humidity, and light. If the requirements are not met, some abnormal situations will occur.
