What are the key points of fertilizing edible fungi? A detailed explanation of the key techniques in one article
There are many types of edible fungi, and common ones include wood ear, shiitake, and oyster mushroom. Because their texture is very smooth and they have high nutritional value, they are favored by consumers. Growing edible fungi is like growing vegetables: in the later stage, fertilizer is applied to increase their mushroom yield. So what are the key points of fertilizing edible fungi?
Key point 1: When fertilizing edible fungi, pay attention to the application method
The methods for adding nutrient solution to edible fungi can be divided into spraying, soaking, and hole irrigation. Now let us look at the key points of all three. For spraying, it should be determined according to the growth time of the fruiting bodies. Generally, spraying can be carried out when a large number of fruiting bodies have grown. Do not spray directly facing the fruiting bodies, so as to avoid side effects. Spraying is not recommended for young mushroom buds, not recommended for mushrooms that have just been picked, not recommended when humidity is too high, and nutrient solution spraying is not recommended when the mushroom house is affected by pests and diseases.
Soaking with nutrient solution is generally used for edible fungi cultivated in bags. After the edible fungi have been harvested for one to two flushes, if the fungus bags are severely short of water, the nutrient solution can be soaked for a while until they return to their original weight. Remember, do not soak for too long. If the fungus bags have lost too much water, they can be soaked several times.
The hole irrigation method is generally used on mushroom beds. If there are many fungi on the mushroom bed and the loss of water and nutrients is too great, the hole irrigation method can be used. The specific operation method is to make holes in the mushroom bed at a certain spacing, then infiltrate the prepared nutrient solution into the mushroom bed, and finally cover it with soil.
Key point 2: The nutritional combination of the nutrient solution must be reasonable
When edible fungi use nutrient solution, it is generally not a single one used alone, but several selected and used in combination. This is helpful for the growth of the fruiting bodies, and the nutrition is more comprehensive.
Key point 3: The concentration of the nutrient solution must be appropriate
If the concentration of the nutrient solution used for edible fungi is too high, it will cause difficulty in the respiration of the mycelium, and in severe cases it will also affect the normal growth of the mycelium or directly damage the mycelium. When the concentration of the nutrient solution is too low, the mycelium does not have enough nutrients, and naturally it will not grow well. Therefore, when adding a certain concentration of nutrient solution to edible fungi, it must be determined according to the water content of the culture material. If the water content is relatively high, the concentration of the nutrient solution can be appropriately increased; if the water content is relatively low, the concentration of the nutrient solution can be reduced.
Key point 4: Use nutrient solution according to environmental changes
If the temperature exceeds 20°C, it is difficult for the mycelium of edible fungi to grow into good fruiting bodies. Of course, except for some high-temperature varieties of edible fungi, at this time there is no need to add extra nutrient solution. If the culture material is infected by bacteria, the bacteria should be dealt with first before using the nutrient solution.
