First, we must pay attention to the addition method There are usually three ways to add nutrient solution: spraying, soaking and filling. The time for spraying the nutrient solution is preferably when a large number of fruiting bodies are present. Spraying should pay attention to the nozzle should not face the fruiting body, but also pay attention to "four no spray": 1, young mushroom buds do not spray, so as not to "swell"; 2 just picked mushrooms or have mushroom residues Spray, so as not to cause bacterial diseases; 3, when the air humidity is too large, do not spray; 4, mushroom shed (room) when the pests and diseases are serious, do not spray. Soaking method is mainly used for bagged edible fungi. After harvesting l-2 mushroom, if the cultivation bag is in a serious water shortage state, it can be immersed in the prepared nutrient solution until it recovers to near the original weight. To add nutrient solution by soaking, just put the bag in the nutrient solution pool and press the weight, but the soaking time should not be too long. If the bag is too watery, it can be soaked several times. The acupoint method is mainly used on the bed of bacteria. This method can be used when the mushroom bed has more mushrooms and the water and nutrient consumption is too large. The specific method is: the bacteria bed is drilled at a hole distance of 10 匣 meters, and the prepared nutrient solution is flooded into the bed, and the soil is covered after the nutrient solution is added.
Second, the concentration should be appropriate When the concentration of nutrient solution is too high, not only the hyphae absorption is difficult, but also hinder or even damage the hyphae; when the concentration is too low, the effect is not obvious, and the high-yield purpose is not achieved. At a suitable concentration, the nutrient solution should be added according to the water content of the culture material: if the water content of the culture material is high, the concentration of the nutrient solution should be increased, the water consumption should be reduced, and the ventilation amount should be increased after the addition. On the contrary, the concentration of nutrient solution should be reduced and the water consumption should be increased.
3. Nutritional nutrients should be comprehensive. Several nutrient solutions should be used alternately, so that the nutrients needed for the growth of fruiting bodies are comprehensive and reasonable. If the growth of the edible fungus is stimulated with a stilbene, it should be used after the nutrient solution has been replenished.
Fourth, we must pay attention to changes in the environment When the temperature reaches 20 ° C or more, the hyphae are difficult to form high quality fruiting bodies. Except for high-temperature edible fungi, no nutrient solution may be added. If the culture material has been contaminated with bacteria, it is necessary to remove the bacteria before adding the nutrient solution. In order to prevent contamination of the bacteria, a certain amount of bacteriostatic agent can also be added at the same time as the nutrient solution is added to prevent the spread of the bacteria.
