Shiitake Mushroom Cultivation Tutorial: A Detailed Guide to the Latest Techniques and Methods
The shiitake mushroom is the star among fungi and the finest of the shiitake varieties, and the higher the yield of shiitake, the better the quality. Shiitake mushrooms are rich in nutrients and can help with fitness, disease prevention, and anti-aging, making them very popular both at home and abroad. Our country's shiitake mushrooms are mainly produced in Hubei, Zhejiang, Henan and other places. So how do you cultivate shiitake mushrooms? Let's learn about its cultivation techniques together.
1. Mushroom shed construction
The shiitake mushroom shed should generally be built on a plot with sufficient light, good permeability and air circulation, flat terrain, and dry soil. Next, when building the mushroom shed, the shed length is about six meters, and both the width and height are 2.5 meters. Bricks need to be laid at both ends and in the middle of the shed, and each wall needs a door about 60 cm wide, with ventilation holes made in the door. Finally, build the tiered racks, generally six layers, and once the film is placed on the racks, the mushroom shed construction is complete.
2. Nutrient preparation
When the temperature can be maintained at around 26°C, shiitake mushroom cultivation can begin, and the best planting time is the end of August each year. Nutrient preparation is very important. Usually, pear trees or other trees with more wood are chosen, and they are crushed into sawdust to make the nutrient material. The ingredients of the nutrient material include sawdust, bran, potassium dihydrogen phosphate, gypsum powder, and lime, mixed in appropriate proportions. Pile these materials on the ground, add an appropriate amount of water, turn and stir the pile, and finally ferment it.
3. Bagging and sterilization
After the nutrient material has fully fermented, it needs to be bagged. Shiitake mushroom cultivation generally uses large bags for bagging the nutrient material. Put the nutrient material into the bags, then tie the openings with cotton thread, place them on the prepared ground, and finally put the bags filled with nutrient material into a normal-pressure sterilization stove for disinfection and sterilization. First, use high heat to bring the temperature to 100°C in about five hours, and keep it at 100°C for a day and a half. At this point, sterilization is complete. When the temperature of the nutrient material drops to around 70°C, the nutrient material can be placed in the mushroom shed, and the nutrient material can be reasonably spread out in the mushroom house.
4. Inoculation management
When inoculating, choose excellent varieties, and disinfect the mushroom house before inoculation. Personnel entering the mushroom house for inoculation also need thorough disinfection and sterilization. When the temperature of the nutrient material drops to 28 or 29°C, inoculation can be carried out. We need to place the spawn evenly in the nutrient material and avoid inoculating the spawn too densely, as this will affect the yield and quality of the shiitake mushrooms.
5. Fruiting management
Fruiting management is the most critical stage in the shiitake mushroom cultivation process, as it directly affects the yield and quality of the shiitake mushrooms. Generally, about four or five days after inoculation, the mycelium will germinate. During this period, we only need to keep the temperature of the mushroom shed at around 28°C, and no other management is needed. After about a week, the mycelium begins to grow. At this time, the temperature of the mushroom shed only needs to be 26°C, and the piles should be turned to ensure that no contaminating bacteria invade. At the same time, provide ventilation two or three times, with each ventilation lasting 30 minutes. Generally, when the mycelium has grown for half a month, this is its vigorous growth period. We need to increase ventilation and keep the temperature at around 23°C. When it has grown for about 50 days, humidity needs to be reasonably controlled at this time to avoid affecting fruiting. Second, temperature also needs to be controlled to avoid mold caused by high temperatures. Generally, fruiting will occur within 70 days at most. After fruiting, it is enough to spray with the mushroom ecological treasure bacterial liquid.
Since the shiitake mushroom is the finest of the shiitake varieties, its cultivation techniques are roughly similar to those for shiitake cultivation, but since it is a premium product, the cultivation techniques and management are naturally more refined, and the requirements for cultivation techniques are also higher.
