In the later stages of mushroom mushrooming, mushroom growers often add nutrient solutions to enhance the stamina. However, only adding the nutrient solution in the right way can achieve the intended purpose. On the contrary, it will be counterproductive and cause losses to the producer.

To pay attention to the method of adding nutrient solution is usually added in three ways: spray, soaking and cavitation.

The time of spraying the nutrient solution is suitable when a large number of fruit bodies are present. Spraying should pay attention to the nozzle is not facing the fruiting body, but also pay attention to the "four not spray": young mushroom buds do not spray, so as not to "swollen"; just picking mushrooms or mushroom residues do not spray, so as not to Cause bacterial diseases; air is not sprayed when the humidity is too high; mushroom shed (house) is not sprayed when the pests and diseases are serious.

Soaking method is used for bagged edible fungi. After harvesting 1-2 oyster mushrooms, if the cultivation bag is in a state of severe water shortage, it can be soaked in a prepared nutrient solution until it recovers or approaches its original weight. The use of soaking method to add nutrient solution, just in the bag after immersed in the nutrient solution can be pressed on the weight, but the soaking time can not be too long, if the bag of water loss can be divided into several times soaking.

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 as follows: The bacteria bed is drilled at a distance of 10 cm, and the prepared nutrient solution is flooded into the bacteria bed, and the soil is added after the nutrient solution is added.

The concentration should be appropriate: if the concentration of nutrient solution is too high, not only the absorption of hyphae will be difficult, but it will also impede or even damage the hyphae. If the concentration is too low, the effect is not obvious and the purpose of high yield cannot be achieved. 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 nutrients should be comprehensive: several nutrient solutions should be used interchangeably, so that the nutrition obtained by fruiting bodies 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 is above 20°C, it is difficult for the hyphae to form high-quality fruit bodies (other than 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.
