Currently on the market, black termite mushrooms are known as expensive and extremely nutritious foods. Most Vietnamese families love to eat black termite mushrooms in their daily meals but don’t know where to buy for quality assurance. Therefore, many people decide to learn and grow black termite mushrooms at home to both have food and small businesses. The article below, we will help you learn about The technique of growing termite mushrooms Black at home is both productive and quality.
Preparing and handling materials for growing black termite mushrooms
With the technique of growing black termite mushrooms, the most important step is still the preparation and handling of raw materials to create an embryonic environment to help the fungus grow and develop best.
The main raw material for making embryo sacs chosen by people is sawdust. The most suitable type of sawdust is sawdust from trees such as rubber, bodhi tree, etc., so using new sawdust is the most effective.
There are 2 ways to mix the most popular black termite mushroom growing embryo sac materials:
- Use sawdust mixed with cornstarch and glucose additives in the ratio of 100kg of sawdust to 3kg of cornstarch and 3kg of cornstarch. glucose. Adjust humidity from 65 – 70%, pH about 7 packed into PE bags, tightly squeeze each bag weighing 1.1 – 1.3kg
- Use moistened sawdust mixed with powdered lime, rice bran at the rate of 100kg of sawdust with half a kg of lime powder, adjust the humidity 65 – 70%, incubate for 15-20 days, mix with 3 – 5 kg of rice bran and then close. into PE bags, each bag weighs 1.1 – 1.3kg
Note that when closing the embryo bag, it should be tightly packed and leave 5-7 cm at the mouth of the bag to insert the bag.
Embryo sac sterilization
After packing all the materials to be processed into each embryo bag, we continue to proceed with the sterilization step of the embryo sac. The purpose of this process is to completely treat the infected bacteria present in the sawdust material, ensuring the best quality of termites.
First, the embryo bags will be placed on a special steaming shelf or basket, not stacked on top of each other. The autoclaving time is from 8 to 12 hours at a temperature of 121 degrees Celsius depending on whether the batch is small or large.
After steaming, people will remove the embryo bag and let it cool for 24-40 hours at normal room temperature.
If you have a need to grow black termite mushrooms in small quantities at home, you can buy sterilized bags of mushroom embryos at stores that sell black termite mushrooms.
Transplanting black termite fungus
After the embryo sac is cooled, it is possible to inoculate the black termite fungus with seed meow or stick meow.
The process of sowing seeds by seed meow
- Heat a bottle of meow like a black termite mushroom on an alcohol lamp for 3-4 minutes to sterilize meow
- Use a sterilized culture spoon to remove embryos from bottles to embryo sacs
- Depending on the size of the seed bag, take about 3 – 5 spoons of embryos from the bottle to
- Shake the embryo bag well so that the black termite fungus-like meow spreads evenly on the surface
- Arrange similar bags on shelves or shelves in the house
The process of inoculating seeds with stick meow
- Use specialized equipment such as sterile scissors or pins to transplant meiosis into the prepared embryo sac
- Each embryo sac usually uses a seed rod
- Transfer the inoculated embryo sacs to the nursery
Note that after transplanting seeds into 5-10 embryo sacs, it is recommended to sterilize the inoculation spoon once to ensure safety and hygiene.
Care and harvest
The process of taking care of embryo sacs implanted with black lip fungus needs to go through 2 stages: good incubation and morning incubation before harvesting. As follows
- Dark incubation period: Lasts from 70 to 90 days, at this time it is necessary to incubate the embryo sacs in the darkest place possible, avoid moisture, the appropriate temperature is about 26 degrees Celsius. During this time, it is necessary to regularly monitor for timely removal of infected mycelium
- Light incubation period: when observing that the mycelium develops about 80% of the embryo sac, remove the neck cap to conduct light incubation. This phase lasts from 10 to 20 days, the appropriate temperature is from 25 to 27 degrees Celsius, no humidity. Until the surface of the embryo turns black, do moisture stimulation at 93-95% humidity and wait for the fungus
- Finally, the stage of harvesting black termite mushrooms for use or business depends on the purpose. Each blastocyst will be harvested multiple times before replacing with a new blastocyst
In general, the technique of growing black termite mushrooms is not too difficult but requires professional knowledge and experience. Therefore, before deciding to grow mushrooms, please carefully refer to the articles from us.
