Summer mushrooms, as fresh produce, are in high demand in the edible fungus market. With advancements in technology, high-temperature strains have recently been introduced into commercial cultivation. The author recommends using water-cooled air conditioning systems and mushrooming techniques to improve yield and quality. By adopting mesophilic strains, the market value of the product has significantly increased. Here are the main measures:
First, the cultivation facilities need to be properly maintained. After completing spring production, the old mushroom bags should be removed, the shed cleaned, and any damaged film repaired. A disinfectant should be sprayed to eliminate pathogens. Then, clean water is poured into the shed, allowing it to soak through before applying lime powder. The bags are then placed on the shelves. For temperature control, a water-cooled air conditioner can be used for cooling in summer and heating in winter.
Second, the basic formula for making mushroom bags includes 1800 kg of wood chips, 200 kg of wheat bran, 20 kg of superphosphate, 3 kg of urea, 20 kg of lime powder, 10 kg of gypsum, and 1 kg of special mushroom additives. Following standard bagging, sterilization, inoculation, and bacterial management procedures ensures a healthy growth environment.
Third, once the bacterial bags are fully colonized and the color is stable, they are arranged in a "well" shape and covered with plastic sheets or straw to help regulate temperature. Adjusting the cover during the day and night helps promote hyphal growth on the surface of the bags and increases the temperature difference, encouraging faster color change.
Fourth, after the color transformation is complete, the bags are moved into the shed, spaced 5 cm apart, and subjected to 1-2 days of cooling via water-cooled air conditioning. This is followed by high-temperature stimulation, along with moisture and light exposure. Within about a week, small mushroom buds will appear. At this stage, regular watering is essential, and the humidity difference should be minimized to ensure consistent bud development. The ideal conditions include a temperature between 20°C and 25°C, humidity between 75% and 95%, and light intensity of 300-1200 lux. Proper ventilation keeps the air fresh and promotes healthy growth.
Fifth, when the mushroom caps are thick enough, the film on the bags needs to be manually cut to allow the mushrooms to emerge. A small knife is used to carefully cut the film at the point where the bud appears, without damaging the mushroom itself. If done carefully, the cut can be made around the bud, reducing the risk of malformed mushrooms. Once the buds start to grow, the temperature should remain between 20°C and 25°C, humidity between 75% and 95%, and light around 500-1000 lux. When the cap diameter exceeds 2 cm, a three-dimensional nutrition essence can be sprayed directly onto the mushrooms. Harvesting should occur when the edges of the cap begin to unfurl. At this stage, greenhouse temperature and foliar fertilization play a key role in determining both yield and quality.
Mushroom stick management is more efficient than traditional bag cultivation, but since the sticks are exposed, they lose more moisture during fruiting. Therefore, maintaining higher humidity and providing water injections is crucial. The harvesting period for shiitake mushrooms is clearly marked. Each time a mushroom is harvested, the bag loses more moisture, so it's important to replenish the water before the next harvest. One common method involves digging a pit, lining it with plastic, placing the mushroom bags inside, and filling the pit with water to create pressure. After 24 hours, the water is drained, and the bags are returned to the shelf for continued growth. This process ensures that the bacteria remain active and the mushrooms continue to develop properly.
