Pest and Disease Control and Fertilization Techniques for Edible Fungi

Application Methods There are usually 3 methods for adding nutrient solution: spraying, soaking and hole irrigation. The best time to spray nutrient solution is when fruiting bodies appear in large numbers. When spraying, make sure the nozzle is not pointed directly at the fruiting bodies, and also observe the "four no-spray" rules: 1. Do not spray on small 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 residues remain, so as to avoid causing bacterial diseases. 3. Do not spray when the air humidity is too high.

4. Do not spray when pests and diseases are severe inside the mushroom shed (room).

The soaking method is mainly used for edible fungi grown in bags. After harvesting 1-2 flushes of mushrooms, if the cultivation bags are in a severely water-deficient state, they can be soaked in a prepared nutrient solution until they recover or come close to their original weight.

The hole irrigation method is mainly used on mushroom beds. When the mushroom bed produces many mushrooms and water and nutrients are consumed excessively, this method can be used. 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.

Proper Concentration When the concentration of the nutrient solution is too high, not only is it difficult for the mycelium to absorb, but it can 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., and the principle of "little but frequent" must be well observed.
