Edible fungus fertilizer should pay attention to what?

In the late stage of edible mushrooms, in order to enhance the stamina, mushroom farmers often use various means to add nutrient solution for top dressing. However, it can only be achieved if it is added in the correct way. On the contrary, if the seedlings are encouraged, they will be counterproductive and cause losses to the producers. First, we must pay attention to the method of adding nutrient solution is usually added in three ways: spray, soaking and cavitation. The time of spraying the nutrient solution is suitable when a large number of fruit bodies are present. Spraying should pay attention to the nozzle is not facing the fruiting body, while paying attention to the "four not spray": 1, young mushroom buds are not sprayed, so as not to "swollen"; 2, just over mushroom or mushroom residues are not Spray, so as not to cause bacterial diseases: 3, when the air humidity is too large, do not spray; 4, mushroom shed (room) serious pests do not spray. The soaking method is mainly used for bagged edible fungi. After harvesting 1-2 mushrooms, if the cultivation bag is in a state of severe water shortage, it can be soaked in a well-matched nutrient solution until it returns to its original weight. Adding Cao Yang liquor by soaking method, just put weight in the nutrient solution pool and put on the bag, but the soaking time should not be too long. If the bag is dehydration too much, it can be divided into several times . The method of irrigating acupuncture points is mainly used on the bed of bacteria. This method can be used when the mushroom bed has many mushrooms and the consumption of water and nutrients is too large. The specific method is as follows: The bacteria bed is drilled at a distance of 10 m, and the prepared nutrient solution is flooded to the bacteria bed, and the soil is added after the nutrient solution is added. Second, the concentration of the nutrient solution concentration is too high, not only the absorption of mycelium is difficult, but also impede or even damage the mycelium; concentration is too low, the effect is not obvious, can not reach the purpose of high yield. At the appropriate concentration, the nutrient solution should be added according to the moisture content of the culture material: If the water volume of the culture material is higher, the concentration of the nutrient solution should be increased to reduce the amount of water, and the ventilation volume should be increased after the addition. Conversely, the concentration of nutrient solution should be reduced to increase the amount of water used. The commonly used potassium dihydrogen phosphate 0.2%, etc., we must grasp the "less and diligent" principle. Third, nutrient solution nutrient should be used in an all-round way should often use several kinds of nutrient solution, so that fruit body growth nutrients needed are both comprehensive and reasonable. If stimulating the growth of edible mushrooms with sensation: it should be used after supplementing the nutrient solution. Fourth, pay attention to changes in the environment When the temperature reaches 20 °C above, the mycelium is difficult to form a high-quality fruit body in addition to high-temperature edible mushroom species, can not add nutrient solution. If the culture material has been contaminated with bacteria, be sure to remove the bacteria before adding nutrient solution. In order to prevent the contamination of bacteria, it is also possible to add a certain amount of bacteriostatic agent at the same time as the nutrient solution is added to prevent the propagation of contaminants.
