How Maitake Mushrooms Produce

2023-02-10

There are two management methods for the fruiting of Grifola frondosa: bag type and imitation of wild fruiting.
Bag-type fruiting - move the fungus bag of the long primordium into the fruiting room, keep the temperature at 20-22°C, the air humidity at 85%-90%, and the light at 200-500 lux. After 3-5 days, remove the ring and tampon, and stand upright. On the bed frame, cover the mouth of the bag with paper, spray water on the paper, and ventilate 2 to 3 times a day, 1 hour each time. After about 20 to 25 days, the caps are fully unfolded and the fungi are picked when the pores are elongated. When picking, you can use a knife to cut off the whole cluster of mushrooms, and pick 2 to 3 tides continuously, with a biological efficiency of 30% to 40%.
Imitation of wild fruiting - the cultivation fungus bag with sawdust as the medium. After the bag is full of mycelium, take off the plastic bag, and arrange the fungus sticks neatly in the pre-dug border, leaving a proper gap between the fungus sticks, And fill the surrounding soil, and cover the surface with a 1-2 cm layer of soil. This is a form of soil-covering cultivation, and the biological efficiency can reach 100% to 120%. This method is far superior to the former (bag-type fruiting), so it will be introduced here.
Bacteria discharge time - Grifola frondosa is cultivated in Tangshan area, and the best time to discharge bacteria is from November to the end of April of the following year. Because at this time, the miscellaneous bacteria and pests in the air and soil are not active and do not invade the mycelium, while the mycelium of Grifola frondosa is resistant to low temperature, the mycelium is closely connected, and the growth is strong, which is beneficial for the mycelium to absorb nutrients. Although the development period is longer in the low temperature period, the mushrooms are discharged early, and the yield is high, and 80% of the yield can be completed before the rainy season. The grifola frondosa planted after the end of April is due to the high temperature and active bacteria. Susceptible to infection, and there will be fast growth of fruiting bodies, small single plant, low total yield, and are vulnerable to high temperature and heavy rain.
Bacteria removal method——①Site: Choose a place that is leeward and sunny, with high terrain, dry, no water accumulation, close to water sources, convenient irrigation and drainage, and far away from toilets or livestock pens.
② Digging pits: It is required to go east-west, dig pits with a width of 45-55 cm, a length of 2.5-3.0 m, and a depth of 25 cm. Walk, manage and drain.
③Preparation work before planting: After the trench is dug, water should be poured once to preserve moisture. After the water dries up, sprinkle a layer of lime on the bottom and side of the ditch to increase calcium and disinfect, then sprinkle a thin layer of trichlorfon powder on the bottom and side of the ditch, and finally spread a small amount of topsoil on the bottom of the ditch.
④Discharging the fungus sticks: Remove all the plastic bags from the fungus bags with good hyphae, and arrange the fungus sticks horizontally and vertically in rows in the ditch. a gap. At the same time, it is necessary to make the upper surface of the fungus sticks discharged in the ditch flush by picking up or padding the back soil at the bottom of the ditch. In this way, 4 to 5 rows of bacteria sticks can be discharged in the ditch.
⑤Fill the gap: Fill the gap between the fungus stick and the fungus stick and the side of the ditch with soil to 1 cm above the fungus stick.
⑥Watering: Put water into the pit to make the soil firm, fill up the gaps or pits with moist soil, and keep the surface soil thickness 1-2 cm.
⑦Wrapping: Use plastic film or nylon bags to wrap the pit around tightly to prevent the soil from falling off the edge of the pit. Before February, it is necessary to spread a layer of film in the border and cover the film with a 5-7 cm soil layer. By mid-April, the film and floating soil in the border should be shoveled to prepare for fruiting management.
⑧Building a shade shed: set up two horizontal bars on the north side of the pit and in the middle of the pit. high slope. Before April, the plastic sheets in the north were spread directly on the ground, and compacted with soil, and vent holes were left on the east and west sides.
⑨Powder gravel: For those covered with floating soil and film in winter, the floating soil and film should be covered with gravel after the removal of floating soil and film. Spread a thin layer of smooth gravel with a diameter of 1.5 to 2.5 cm in the border.
