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) does not spray when the pests are serious. The soaking method is mainly used for edible fungi in bagged plants. After harvesting l~2 oyster mushrooms, 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. Adding Cao Yang solution by soaking method, you only need to put the weight bag in the nutrient solution pool and press the heavy object, but the soaking time should not be too long. If the bacteria bag loses too much water, 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 volume should be increased after the addition. On the contrary, the concentration of nutrient solution should be reduced and the water consumption should be increased. Commonly used potassium dihydrogenate 0.2%, etc., we must grasp the principle of "less and diligent".
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 fungus is used to stimulate the growth of the edible fungus: it should be used after the supplemental nutrient solution.
Fourth, we must pay attention to changes in the environment When the temperature reaches 20 ° C or above, it is difficult to form high-quality fruit bodies. In addition to high-temperature edible fungi, no nutrient solution can 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 the contamination of the bacteria, it is also possible to add a certain bacteriostatic agent at the same time as adding the nutrient solution to prevent the breeding of the bacteria and spread the agricultural technology promotion center of the county.
