Edible fungus to pay attention to methods
In the later stages of mushroom mushrooming, mushroom growers often add nutrient solutions to enhance the stamina. There are usually three ways to add nutrient solution: spraying, soaking and burrowing. It is advisable to use a large number of fruit bodies when spraying, and it should be noted that the nozzles should not face the fruit body. The soaking method is mainly used for bagged edible fungus. After the harvesting of 1 to 2 oyster mushrooms, if the cultivation bag is in a state of serious water shortage, it can be soaked in a well-matched nutrient solution until it recovers or approaches the original. When it's weight. The method of irrigating acupuncture points is mainly used on the bed of bacteria. This method can be used when the mushroom bed has many mushrooms and the consumption of water and nutrients is too large. The specific method is to drill the bed of bacteria at a distance of 10 cm, diffuse the prepared nutrient solution into the bed of bacteria, and cover the soil after adding the nutrient solution. In the specific operation, we should pay attention to the following aspects: If the concentration of the nutrient solution is too high, not only the absorption of mycelia will be difficult, but it will also impede or even damage the growth of the mycelium; if the concentration is too low, the effect is not obvious and can not be achieved. The purpose of high yield. The concentration of the nutrient solution also depends on the moisture content of the culture material. If the moisture content of the culture material is high, the concentration of the nutrient solution should be increased to reduce the amount of water, and the amount of ventilation should be increased after the nutrient solution is added. Conversely, the concentration of nutrient solution should be reduced to increase the amount of water used. Nutritive nutrient solution should be used in a nutshell to alternately use several nutrient solutions, so that the nutrition obtained by the fruiting body is comprehensive and reasonable. If hormones are used to stimulate the growth of mushrooms, they should be used after supplementing the nutrient solution. Pay attention to changes in the environment When the temperature reaches 20°C or higher, hyphae are difficult to form high-quality fruit bodies (except high-temperature edible mushroom species), and no nutrient solution can be added. If the culture material has been contaminated with bacteria, be sure to remove the bacteria before adding nutrient solution. In order to prevent bacterial contamination, a certain amount of bacteriostatic agent may also be added at the same time as the nutrient solution is added to prevent the growth of germs.
