In the late stage of mushroom mushrooming, in order to enhance the stamina of the mushroom, the mushroom farmer often adds fertilizer by adding nutrient solution. Only in accordance with the principle of "two adaptations and two requirements" can we achieve the intended purpose.
The method of addition should be suitable. There are usually three ways to add nutrient solution: spraying, soaking and burrowing. 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, while paying attention to the "four does not spray": young mushroom buds are not sprayed, so as not to "swollen": just picked mushroom or mushroom residues do not spray, so as not to cause Bacterial diseases; Do not spray when the air humidity is too high; Do not spray when the pests and diseases are serious in the shed (house). The soaking method is mainly used for bagged edible fungi. After harvesting 1-2 tidal mushrooms, if the growing bag is in a state of severe water shortage, it can be soaked in a well-matched nutrient solution until it returns to its original weight. The soaking method is used to add the nutrient solution. Generally, the bacterial bag is put into the nutrient solution pool and the heavy object is pressed, and the soaking time cannot be too long. If the bag has lost too much water, it can be soaked several times. The method of irrigating acupuncture points is mainly used on the bed of bacteria. This method can be used when the mushroom bed has more mushrooms and the water and nutrients are consumed excessively. 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 bacterial bed, and the soil is added after the nutrient solution is added.
Add concentration should be appropriate. When the concentration of the nutrient solution is too high, not only the absorption of the hyphae is difficult, but also the growth of the mycelium is hindered or even damaged; when the concentration is too low, the high yield cannot be achieved. The concentration of nutrient solution to be added 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 addition; otherwise, the nutrient solution should be reduced. The concentration increases the amount of water used.
Nutrient solution nutrients should be comprehensive. Several nutrient solutions should often be used interchangeably, so that the nutrients required for fruit body growth are both comprehensive and reasonable. If hormones are used to stimulate the growth of mushrooms, they should be done after supplementing the nutrient solution.
Pay attention to changes in the environment. When the temperature reaches 20°C or above, the mycelium is difficult to form a high-quality fruit body, and no nutrient solution may be added except for high-temperature edible mushroom species. If the culture material has been contaminated with bacteria, be sure to remove the bacteria before adding nutrient solution. In order to prevent the contamination of bacteria, a certain amount of bacteriostatic agent can also be added at the same time as the nutrient solution is added to prevent the growth of germs.
