Taiwan cultivates new method of mushroom cultivation in space
2020-12-24 14:27:47
Most of the raw materials used to cultivate shiitake mushrooms in Taiwan are mainly wood chips of hardwood species such as Fagaceae and birch families. They must be dried and composted for half a month before being used; hard trees need to be used for more than half a year.
The space bag is a PP plastic bag, generally 22 to 25 cm long and about 12 to 14 cm in diameter. The formula for the culture material in the space package is generally the same as the conventional formula. The biggest difference is that no sugar is added. Specific formulations are: 1, 100 kg of wood chips, 0.8 kg of gypsum powder, water amount. 2. Wood chips 100 kg, rice bran 6 kg, bran or corn flour 3 kg, gypsum powder 0.4 kg. 3, crumbs 100 kg, rice bran 10 kg, glucose 0.5 kg. The above formulas sometimes add preservatives, commonly used "decay 60% wettable powder", 0.2% water content per kilogram of culture material plus nutrients is generally 55% ~ 60%, pH value of 5 ~ 5.5 material mix bagging The actual charge is about 18 cm deep. Then use a press to press 16 cm into a space package. A hole with a diameter of 2.5 cm and a depth of 10 cm is punched in the center, covered with a plastic collar, sealed with a tampon and transferred to a sterilization pot for sterilization. The difference from the conventional sterilization method is the steam temperature Up to 90°C to 95°C for 4 hours. Sterilizing temperature is too high to easily produce Streptomyces, the temperature is too low will produce green mold.
Inoculation and culture are basically the same as conventional methods. About 60 to 70 days after inoculation, the hyphae of the epidermis bulge and the plastic collar needs to be removed until the epidermis is hardened and the tampon is removed. If there is a mushroom house with moisturizing conditions, the space bag can be peeled off from the entire plastic bag; otherwise, only one circle around the space package needs to be cut to the bottom. There are three ways to promote space capsules:
1. Place the space bag upside down on the plastic pad of the truss frame and water it in plenty. When the brown pellicle film breaks in half, straighten and continue to water.
2. Move the space package to the ground 2-3 times, and then water a lot until the bud grows.
3. Cover the space bag with plastic film and maintain a certain humidity until the bud grows.
After emergence of mushroom buds, continue to water for 2-3 days. After seeing obvious differences between the cap and stipe, use ground irrigation or air spray to keep the humidity of the mushroom house at around 85% to 90%. Harvested. After a tidal mushroom is harvested, it should be ventilated and dry. In addition, the space bag must be placed horizontally to facilitate the return of moisture. Each space pack can take 5--6 shiitake mushrooms.

The non-invasive/high-flow integrated ventilator (BPAP-HE) is a non-invasive ventilator, a high-flow respiratory humidifier, or a high-performance humidifier.
The non-invasive ventilator mode of this product can be used for adult patients who do not rely on invasive ventilation support, such as respiratory dysfunction, to provide ventilation assistance and respiratory support;
Products with high-flow heating and humidification mode can be used for humidification and oxygen therapy for adult patients with spontaneous breathing.
