How to plant tremella fuciformis to germinate
Let's talk about how to plant tremella fuciformis to germinate and the high-yield planting techniques of tremella fuciformis with some small experiences in plant cultivation. Next, the editor will introduce to the netizens.
Tremella fuciformis, also known as tremella fuciformis, is one of the most popular health foods. Initially, tremella fuciformis is a type of jelly fungus that grows on dead wood. It is distributed in the vast regions of China. At present, almost all regions in the country have artificial tremella cultivation. Practice has proven that cultivating tremella mushrooms indoors on shelves can increase the yield by 25%. Now, the drying of dry tremella fuciformis is 16-20 kg, and the following is an introduction to the high-yield cultivation techniques:
Tremella fuciformis is a heterotrophic organism that can only decompose and absorb ready-made organic matter to form its own substances. The mycelium of tremella fuciformis can directly use simple carbohydrates such as glucose and sucrose, but is basically not suitable for starch. The optimal temperature for the germination and planting of tremella fuciformis is 22-25°C. The growth period of the mycelium is 40%. The moisture content of the culture medium is 40%. In the ear stage, the moisture content of the culture medium is 45%, and the relative humidity of the air is 90-95%. It should. Tremella fuciformis is an aerobic fungus that is prone to ear rot and bacterial growth in a humid environment. The development of the fruiting body of tremella fuciformis requires a certain amount of scattered light. It is difficult for the fruiting body to occur in complete darkness, but strong sunlight can lead to the death of spores and mycelium. The suitable pH value for the growth of tremella fuciformis and mycelium is 5.2-5.8.
A special cultivation room can be built in a place with slightly higher terrain, convenient transportation, close to a water source, and easy to clean, or a simple ear shed can be set up in the courtyard, or a place suitable for cultivation in the living room.
Good ventilation, sufficient light. Use bamboo as the framework to build a shelf in the cultivation room or ear shed, about 2.5 m high and 25-50 cm wide (one bag, 25 cm wide horizontally), spaced 30 cm apart, with a total of 8 layers. The shelves are covered with bamboo and wood. The room is surrounded by plastic film to improve insulation and moisture retention. Before use, the cultivation room is disinfected with Sur and dichlorvos.
Cottonseed hulls are the ideal raw material for planting tremella fuciformis, and the yield per unit area can be increased by 20% to 30% compared to wood chips. Corn cobs, peanut shells, and sunflower seed shells can be used for cultivation after drying and crushing. The formula can be adjusted according to local resources. We recommend the following two empirical formulas:
100 kg cottonseed hulls, 25 kg wheat bran, 4.2 kg gypsum powder, 0.4 kg urea, 0.4 kg lime powder,
100 kg sawdust, 30 kg wheat bran, 4.2 kg gypsum powder, 0.4 kg urea, 0.4 kg lime powder, 0.5 kg magnesium sulfate.
In the above formulas, add 100-115 kg of water, mix and stir well, screen and break up lumps to make the moisture content preferentially 55-60%.
Use low-pressure polyethylene film measuring 12 cm x 50 cm as the ear bags. Each kilogram of breeding material can accommodate 220-250 ear bags, and the bags should be tightly packed with the mouth sealed with gauze. Then, use a punch to make 4 to 5 holes on the front of the ear bags, with a diameter of 1.2 cm and a depth of 1.5 cm. Seal the holes with 3.3 cm x 3.3 cm tape. To prevent the culture from becoming sour, mix until the bagging is finished. It should be completed within 5 hours and disinfected in time after bagging. The specification of the atmospheric pressure sterilization furnace should be suitable for a capacity of 1000 bags. After starting the sterilization, the fire is fierce, and the temperature rises to 100°C within 4 hours, then maintaining a high to medium heat for about 15 hours to complete the sterilization. After disinfection, pick up the ear bags while hot to prevent the tape from getting wet.
How to plant tremella fuciformis to germinate
Tremella fuciformis is a moderate-temperature fungus suitable for spring and autumn. Inoculation is carried out in a special sterile room and can only be performed when the feed temperature drops to 30°C. First, dig a thin layer of old mycelium on the inner surface of the tremella bottle, then dig down 3 cm, crush the tremella and mix well, open the bag, and then transfer the strain the size of a broad bean to the holes with the inoculant and reapply the tape. About 30 bags can be inoculated with one bottle of bacteria.
After inoculation, move the ear bags to the roof frame to pile up bacteria. Keep the room temperature at 28-30°C for the first 4 days, and then control the room temperature at 25°C after 5 days. After 5 days, the mycelium develops towards the holes. At this time, flip the stake over and check for contamination. If there is any bacteria in the holes, kill it with formaldehyde injection. From the 5th day, place the ear bags in order on the shelves, with a distance of 1 cm between the bags. During the mycelium cultivation process, if the temperature is too low, coal can be used to raise the temperature, but attention should be paid to ventilation to remove carbon dioxide. At this time, the relative humidity in the room should be kept below 70% and ventilated 1-2 times a day, each time for 30 minutes. If the temperature is suitable, the windows can be opened for a long time to keep the air fresh. After about 10 days of cultivation, when the diameter of the colony reaches 10 cm, the mycelium between the two holes will connect, lift the tape, and leave the hole the size of a soybean to increase oxygen supply and accelerate mycelium growth.
Before removing the tape, use dichlorvos for indoor spray disinfection. After removing the tape for 12 hours, to prevent moisture loss from the culture medium, increase the humidity. Spray water 3 to 4 times a day. Do not spray water into the holes and ventilate. After 4 days, white hair-like mycelium (commonly known as white hair balls) gradually appear at the acupuncture points. At this time, the room temperature should be reduced to 20-23°C, and the relative humidity should be increased to 80-85%. As the mycelium matures physiologically, light yellow beads appear on the white hair balls. At this time, flip the holes to allow the yellow water to drain from the holes and raise the room temperature to 25 degrees Celsius to shrink the yellow water. Usually, when the white earplugs gradually appear in the holes 15 to 16 days after inoculation, the tape should be removed, and the ear bags should be covered with newspapers and sprayed with water to keep the moisture.
After 18 days of inoculation, the young ears in the holes of the ear bags are basically aligned. To make tremella fuciformis more productive, the number of points should be increased to increase oxygen. Cut the film around the edge of the ear holes with a blade about 1 cm, making the diameter of the needle holes 4 cm, and the mycelium in the bag will increase the oxygen contact. During the ear stage, spray water on the covered newspapers 1 to 2 times a day. It is best to keep it slightly moist. The water should not be too heavy; when the fruiting body grows to 3 cm, remove the newspaper, dry and disinfect it in the sun, and then cover it again. Repeat every 3 days. After removing the newspaper each time, cover it every 12 hours to expose the fruiting body to more oxygen. As the fruiting body grows, gradually increase the amount of water sprayed and adjust the watering and ventilation according to the weather conditions, and combine watering to maintain moisture to prevent the earplugs from drying. Usually, about 30 days after inoculation, when the diameter of the fruiting body grows to 12 cm, stop spraying water on the newspapers to prevent the ears from becoming too wet and moldy. After stopping the water, wait for 5-7 days for the ears to gradually thicken and mature before harvesting in time.
