Detailed Explanation of Shiitake Mushroom Cultivation Techniques and Management Methods
Find a flat, sunny piece of land to build a mushroom shed, and control the temperature inside the shed at 26-28°C. Then mix sawdust, wheat bran, gypsum powder, lime, potassium dihydrogen phosphate, etc. together into a culture substrate, put it into bags and sterilize for 6-7 hours. Finally, inoculate in the morning or evening. After successful inoculation, sprouts will appear within 6 days. At this time, do a good job of basic management such as water and temperature, and mushrooms can be produced in about 60-70 days.
High-yield shiitake mushroom cultivation techniques:
1. Mushroom shed construction, mushroom species selection and cultivation time
For shiitake mushroom cultivation, ventilation is needed at all times. On flat terrain, the length of the high shelf in the mushroom shed is 2.4 m, and the width and height each need to be 6 m and 2.6 m; shiitake mushrooms have just been planted and become effective under long-term low temperature. The selection of a good shiitake mushroom strain is to choose a configured strain that can grow at a relatively low temperature. The average daily temperature is best at 26 to 28°C. After meeting the requirement for mycelial growth for 60 to 70 days, the bags become fully colonized, and after another 10-15 days there can be different color changes. Generally, small shiitake mushrooms can appear in November.
2. Preparing the culture substrate
Prepare cultivation materials, preferably sawdust. Use a grinder to formulate a culture substrate from 2 kg potassium dihydrogen phosphate + 175 kg wheat bran + 18 kg gypsum powder + 2 kg lime. Use branches of apple, pear, peach and other broadleaf trees and tung oil trees. Add 2 kg lime powder to the selected prepared medium. Turn and stir these nutrients 3-4 times. On the other hand, improve the sprayable mixture of the substrate, which can inhibit harmful bacterial fermentation.
3. Bagging and sterilization
Complete this within 6-7 hours. Place in a plastic cylinder, and after covering the ground with bags to produce a good nutrient polyethylene film, load the tape into a sterile pressure tank, light the fire, while keeping the tank temperature at 70°C. Indoor inoculation needs to be transported to 100°C within 4-6 hours.
4. Shiitake mushroom inoculation
Sometimes, everyone chooses a good product and disinfects it before inoculation, leaving it for 7-10 days for inoculation. In a room with 0.5 km of sterile formaldehyde gas, open for fumigation for 4 days. Inoculation should be carried out in the morning or evening.
5. Cultivation management
After inoculation in shiitake mushroom cultivation management, sprouting will occur in 1-6 days, and no ventilation is needed. At this time, it is necessary to control the indoor temperature within only 28°C. For shiitake mushrooms at 7-10 days, control the temperature below 26°C and ventilate for 30 minutes each time. Strong demand for growth at 11-15 days, ventilate, and culture at a controlled temperature of 24°C. Shiitake mushroom inoculation will not be less than 16-20 days. At this time, the fungus bags have also reached 22-24°C. To prevent aging, the temperature must be controlled and ventilation and exhaust increased. The mycelium will cover the fungus bags in 45 days, and at 50-60 days when raised, attention should be paid to water drainage. The time for mushroom production is 60-70 days, and management of the transferred mushroom production period needs to be done well.
The above is the relevant introduction to shiitake mushroom cultivation techniques. I hope it is helpful to everyone.
