Method for adding edible fungus nutrient solution for fruiting

The addition of edible mushroom fruiting nutrient solution is very important. How should edible mushroom fruiting nutrient solution be added? The time to spray the nutrient solution is appropriate when the fruit bodies appear in large numbers. When spraying, it should be noted that the nozzle should not face the fruiting body, and at the same time, pay attention to the "four no sprays":
1. Do not spray young mushroom buds to avoid "swollen and dead".
2. Do not spray the mushrooms that have just been picked or the residues of the mushrooms, so as not to cause bacterial diseases.
3. Do not spray when the air humidity is too high.
4. Do not spray when the pests and diseases in the mushroom shed (house) are serious.

The soaking method is mainly used for edible fungi grown in bags. After harvesting 1~2 stalks of mushrooms, if the cultivation bag is in a serious water shortage state, it can be soaked in the prepared nutrient solution until it recovers or is close to its original weight.

The acupoint irrigation method is mainly used in the fungus bed, and this method can be used when the fungus bed produces a lot of fruit and the consumption of water and nutrients is too large. The specific method is as follows: punch holes in the bacterial bed at a distance of 10 cm, flood the bacterial bed with the prepared nutrient solution, and cover soil after adding the nutrient solution.

When the concentration of the nutrient solution is too high, it will not only be difficult for the mycelium to absorb, but also hinder or even damage the mycelium. When the concentration is too low, the purpose of high yield cannot be achieved. If the water content of the culture material is high, the concentration should be increased, and the ventilation should be increased after adding the nutrient solution. On the contrary, the concentration of nutrient solution should be reduced and the water consumption should be increased. The commonly used nutrient solution concentrations are: 0.3%~0.5% urea, 0.2% potassium dihydrogen phosphate, etc., we must grasp the principle of "less and frequent".

Nutrients should be used alternately several nutrient solutions, so that the nutrients obtained by the fruiting bodies are comprehensive and reasonable. If hormones are used to stimulate the growth of edible fungi, they should be used after supplementing the nutrient solution.

Environmental changes When the temperature is above 20 ℃, except for the high temperature edible mushroom varieties, no nutrient solution can be added. If the culture material has been contaminated by miscellaneous bacteria, be sure to remove the miscellaneous bacteria before adding nutrient solution. In order to prevent the contamination of miscellaneous bacteria, a certain amount of bacteriostatic agent can also be added while adding the nutrient solution to prevent the growth and spread of miscellaneous bacteria.
