1. Supplementary method:

The methods of supplementing nutrients to edible fungi include spraying, pouring and soaking. The most common method is to prepare a certain concentration of nutrient solution and spray it on the bacterial bed and bacterial block in combination with supplementary water. When spraying in the young bud stage, pay attention to spray the nutrient solution on the mushroom-free place or near the small mushroom bud, and rinse the fruiting body with water after spraying. It is best to spray the nutrient solution when the tide is low, and the fungus block, fungus stick and basswood can also be supplemented by soaking, that is, let it absorb enough in the prepared nutrient solution and take it out, usually after the harvest of each tide mushroom. conduct. It can also be supplemented by perfusion method on the mushroom bed, that is, the covering soil on the mushroom bed is removed, the funnel is inserted into the culture material, and the nutrient solution is poured into it and then covered. Generally, the distance between the irrigation holes is 10-15 cm, and each hole is filled with about 5 ml of nutrient solution.

2. Balance supplements:

When supplementing nutrients, attention should be paid to alternately supplementing or mixing different nutrient solutions, and try to maintain a nutrient balance to meet the needs of edible fungi for different nutrients. If one of these nutrients is supplemented for a long time, it is difficult to receive the expected yield increase effect. On the mushroom bed, generally, the nutrient solution for adding nutrients should be applied first, and then the high-efficiency nutrient should be applied, so as to facilitate the growth of fruit bodies. If the hormone method is used to stimulate the growth of edible fungi, hormones should be used after supplementation of nutrients.

3. Appropriate amount of supplement:

The amount of nutrient solution should be appropriate. If the supplement is excessive at one time, the culture material will be too wet, which is extremely unfavorable for the growth of mycelium. Therefore, the humidity of the culture material should be properly applied when supplementing. If the humidity of the medium is high, it should be appropriately increased. Concentration of nutrient solution, reduce water consumption, and increase ventilation to disperse moisture after application.

4. Pay attention to the environment:

Generally, when the temperature is higher than 20 ℃, it is difficult for mushroom mycelia to form fruiting bodies, and the rehydration should be stopped. Glucose solution, soy milk juice, human feces and urine should not be used when the temperature is higher than 8°C. If the bacterial bed (block) has been infected with miscellaneous bacteria, it must be cured before rehydration.
