What are the common mistakes in oyster mushroom cultivation? The latest rundown is here
Oyster mushrooms are very common in our daily lives. Because oyster mushrooms taste delicious, are affordable and rich in nutritional value, they are welcomed by many people. So oyster mushrooms are now cultivated in most areas of our country, and many people, when cultivating oyster mushrooms, have many misunderstandings for various reasons. So today, the editor has brought you the common mistakes in oyster mushroom cultivation. Let's take a look below!
1. Improper site selection
When cultivating oyster mushrooms, site selection is very important. If oyster mushrooms are cultivated in dark, poorly ventilated places, they are prone to contamination by various weed molds, leading to failure of oyster mushroom cultivation. If air circulation is poor, the carbon dioxide content in the mushroom house increases, and oyster mushrooms are prone to poisoning and damage, unable to fruit or producing deformed mushrooms. Therefore, when cultivating oyster mushrooms, we should cultivate them in a place with good ventilation, sufficient scattered light and clean sanitation, and do a good job of disinfection. For a site used for cultivation for the first time, use limewater to brush the walls, spread quicklime and take other disinfection measures. Old mushroom houses should be fumigated and disinfected to ensure normal growth of oyster mushrooms.
2. Unsuitable substrate
Many people, when cultivating oyster mushrooms, use contaminated or clumped raw materials for cultivation, causing large-scale contamination of oyster mushrooms and failure of mycelial growth. Or when preparing the substrate themselves, they add too much urea and other nitrogen fertilizers to the substrate. And nitrogen fertilizers easily produce large amounts of ammonia gas, causing poisoning of the mycelium and failure of mycelial growth. Therefore, we must pay attention to the quality of the substrate, keep the raw materials clean, and do a good job of disinfection. Do not add chemical raw materials casually; only during pile fermentation may an appropriate amount of nitrogen source be supplemented. Then special attention should be paid to the moisture of the substrate, which must not be too high or too low, otherwise it will also be very unfavorable to the mycelial growth of oyster mushrooms.
3. Improper selection of spawn
When cultivating oyster mushrooms, the selection of spawn is also very important. We need to reasonably select suitable spawn according to seasonal changes. If the spawn is improperly selected, it will be very unfavorable to the growth of oyster mushrooms. For example, choosing high-temperature varieties in winter, and choosing low-temperature varieties in spring. Or at sowing time, the spawn has already aged or been contaminated. All of these will affect the mycelial growth and fruiting of oyster mushrooms, or even result in no mycelial growth or fruiting. Therefore, be sure to choose suitable spawn, and do not use aged or contaminated spawn.
4. Poor management
Poor management is the most common mistake many people make when cultivating oyster mushrooms. During the fruiting period of oyster mushrooms, an appropriate amount of scattered light is needed. If the light is insufficient, the fruiting of oyster mushrooms will be slow. Then moisture must also be controlled well; do not blindly increase the amount of water sprayed just to increase humidity, as this can easily suffocate the small mushrooms. Spraying into the air should be the main method, and ventilation and air exchange should also be done well to prevent excessive carbon dioxide indoors from affecting the formation of fruiting bodies. Finally, pay attention to the harvesting method; do not harvest the large ones and leave the small ones just to increase yield.
The above is a brief introduction to the common mistakes in oyster mushroom cultivation. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
