How to grow high-yield reishi mushrooms? Master these cultivation key points

Reishi mushroom is a very precious medicinal material, especially aged reishi, which is even rarer. However, many prescriptions require reishi, and wild reishi resources are far from sufficient. In addition, the price of reishi on the market is also very considerable, so a new type of artificially cultivated reishi was developed to meet market demand. Below, Qinnong Network brings you the key technical points for high-yield reishi cultivation, hoping to be helpful to all friends.

1. Nutrient management

The nutrients for reishi cultivation are the foundation of its growth, so nutrient management is very important. Generally, before planting reishi, we need to prepare sawdust and wheat bran, as well as necessary fertilizers. We mix the sawdust, wheat bran and urea evenly, let it sit for a few hours, and then it is ready for filling. Of course, the wheat bran can be replaced with rice straw powder or corn stalk residue, and the urea can also be replaced with ammonia fertilizer. The effects are all very good. Everyone can prepare several kinds of nutrients.

2. Filling management

After the nutrients are prepared, it is time for filling. For filling, we can use ordinary plastic bags, about two hundred to three hundred grams per bag. When filling the bags, pay attention to one point: they should be firm and the surface should be flat. Then poke an air hole in the middle, seal the opening with a cotton plug, and wrap a layer of kraft paper on the outside. Of course, the nutrients can also be put into bottles, and the bottling method is the same as bagging.

3. Sterilization management

Because the nutrients during preparation, as well as the bags and bottles used for filling, may contain a large number of bacteria, we need to sterilize them to ensure the healthy growth of reishi. We put the filled bags and bottles into a pressure cooker for high-pressure sterilization, so that inoculation can be carried out the next day. If we use normal-pressure sterilization, we must inoculate immediately after sterilization, otherwise bacteria will invade.

4. Inoculation management

The environmental requirements for inoculation are very strict. It is best to have a dedicated inoculation room. When entering the inoculation room, the tools used for inoculation need to be disinfected. Next, the inoculation personnel need to disinfect themselves. Then use tools to take out the cultured spawn and put it into the bags or bottles filled with nutrients, then seal the bags or bottles, and place them in a culture room at about twenty-five to twenty-eight degrees for cultivation. After about one month, mushroom buds will grow, and then the temperature needs to be raised by about one degree higher, and growth continues. When its surroundings become hard, it can be harvested.

5. Disease control

During the growth process, reishi is easily infected by pathogens. The main fungi that harm reishi growth are Penicillium, Mucor, and Rhizopus, etc. The control method is that we need to do a good job of sterilization before inoculation. Next, dig out the bark with fungal damage. Finally, if reishi seriously infected by pathogens is found, it should be discarded in time, or alcohol can be applied to the infected area. Never use pesticides for control, because it will cause reishi to carry residual pesticide components, and then it cannot be used as medicine.
