What are the correct methods for topdressing edible fungi during the fruiting period?

Topdressing edible fungi during fruiting has many benefits, as it can greatly improve the quality and quantity of edible fungi fruiting, so doing a good job of topdressing edible fungi during fruiting is an important step in increasing economic value. Today, the editor will share this with everyone.

Adding methods There are usually 3 methods for adding nutrient solution: spraying, soaking and hole irrigation. The time for spraying nutrient solution is best when fruiting bodies appear in large numbers. When spraying, be careful that the nozzle is not pointed directly at the fruiting bodies, and also pay attention to the "four no-spray" rules: 1. Do not spray on young mushroom buds, so as to avoid "swelling them to death". 2. Do not spray on places where mushrooms have just been harvested or where mushroom remnants remain, so as to avoid causing bacterial diseases. 3. Do not spray when air humidity is too high. 4. Do not spray when pests and diseases are severe inside the mushroom shed (room).

Topdressing edible fungi during fruiting can adopt the soaking method, mainly used for bag-cultivated edible fungi. After harvesting 1~2 flushes of mushrooms, if the cultivation bags are in a state of severe water shortage, they can be placed in a prepared nutrient solution to soak until they recover or approach their original weight.

Topdressing edible fungi during fruiting can adopt the hole irrigation method, mainly used on mushroom beds. This method can be used when the mushroom bed produces many mushrooms and water and nutrients are consumed excessively. The specific method is: punch holes in the mushroom bed at a spacing of 10 cm, flood the mushroom bed with the prepared nutrient solution, and cover with soil after adding the nutrient solution.

Appropriate concentration When the nutrient solution concentration is too high, not only is it difficult for the mycelium to absorb, but it will also hinder and even damage the mycelium. When the concentration is too low, the goal of high yield cannot be achieved. If the water content of the culture material is relatively high, the concentration should be increased, and ventilation should be increased after adding the nutrient solution. Conversely, the concentration of the nutrient solution should be reduced and the amount of water used should be increased. Commonly used nutrient solution concentrations are: urea 0.3%~0.5%, potassium dihydrogen phosphate 0.2%, etc. Be sure to grasp the principle of "less but frequent".

Topdressing edible fungi during fruiting should have comprehensive nutrients. Several nutrient solutions should often be used alternately, so that the nutrients obtained by the fruiting bodies are both 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 reaches above 20°C, except for high-temperature-type edible fungi varieties, nutrient solution may not be added. If the culture material has already been contaminated by miscellaneous bacteria, be sure to remove the miscellaneous bacteria first before adding nutrient solution. In order to prevent contamination by miscellaneous bacteria, a certain amount of bacteriostatic agent can also be added while adding the nutrient solution, to prevent miscellaneous bacteria from breeding and spreading.

That is all for the methods of topdressing edible fungi during fruiting. I believe everyone has gained a certain understanding, and I hope this article is helpful to everyone.
