What environmental conditions does wood ear mushroom need to grow? A detailed explanation of the latest requirements

Wood ear mushroom is a kind of fungal vegetable, and its cultivation method is completely different from ordinary vegetables. During cultivation, its growing environment has certain requirements. For example, temperature, moisture, nutrients and so on are all indispensable when cultivating wood ear mushroom. Otherwise, the growth of wood ear mushroom will be seriously affected. So what exactly are the requirements of wood ear mushroom for the environment? Below, the editor brings you the environmental conditions needed for wood ear mushroom growth. Let's take a look!

1. Nutrients

Wood ear mushroom has a very high demand for nutrients during its growth process, and it needs to obtain nutrients such as nitrogen, carbon and inorganic salts from the cultivation substrate. Sufficient nutrients can ensure the growth of wood ear mushroom. Therefore, during cultivation, in order to promote the growth of wood ear mushroom mycelium, an appropriate amount of wheat bran, rice bran and other substances with high nitrogen content should be prepared. Wood ear mushroom also needs certain inorganic salts such as calcium, phosphorus and magnesium, so wood is generally used as the cultivation substrate.

Each growth stage of wood ear mushroom has different temperature requirements. For example, during the fruiting body stage, the temperature should be maintained at around 23 degrees, and the most suitable temperature for mycelium growth is between 23-28 degrees. Within the suitable temperature range, if the temperature is lower, although the growth cycle is longer, the fruiting bodies grow well and have strong quality. If the temperature is high, it is easy to cause excessive vegetative growth of mycelium, and yield and quality will decline. Moreover, if it is high temperature and high humidity, it can also cause the fruiting bodies to rot and produce the phenomenon of "flowing ear."

3. Moisture

Just like the temperature requirements of wood ear mushroom, each growth stage has different moisture requirements. During mycelium growth, the water content of the log should be maintained at around 38%, and the water content of the culture material should be maintained at 58%. Air humidity must also not be lower than 70%. When it reaches the fruiting body formation stage, the moisture requirements are higher, and air humidity should be increased to 92%. When it is lower than 80%, the growth of fruiting bodies will be seriously affected.

4. Air

Wood ear mushroom growth requires good air, so during cultivation it is necessary to ensure that the planting site is sufficiently permeable and has air circulation, to meet the oxygen demand for the growth of wood ear mushroom mycelium. If the planting site is too enclosed and not easy to ventilate, the expansion of the wood ear mushroom fronds will be hindered, and deformed wood ear mushrooms such as chicken-claw ear are easily formed, causing them to lose commercial value. Ensuring good ventilation can also reduce the phenomena of wood ear mushroom becoming moldy and rotting and being infected by miscellaneous bacteria.

5. Light

During the mycelium growth stage, wood ear mushroom basically does not need light. However, during the fruiting body growth period, a certain amount of light is needed, but care should be taken not to let direct sunlight hit it, with scattered light being the main type. During the fruiting body stage, if it is completely in a dark environment, wood ear mushroom is not suitable for forming fruiting body primordia, and insufficient light will also inhibit the growth of fruiting bodies. Therefore, during cultivation, it is necessary to ensure sufficient scattered light to promote the growth of wood ear mushroom.

The above is a brief introduction to the environmental condition requirements for wood ear mushroom growth. The cultivation substrate for wood ear mushroom is not soil, but wood. Therefore, in management, it is very different from ordinary vegetable field management. So these are not only the environmental requirements for wood ear mushroom growth, but also the management work we need to do well during cultivation. Everyone must pay close attention. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
