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. By adopting the correct method of "two suits and twos", topdressing can achieve the intended purpose.
1 Select the appropriate addition method. There are three ways to add nutrient solution: spraying, 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 does not spray": young mushroom buds do not spray, so as not to "swollen": just picked mushroom or mushroom residues do not spray, so as not to cause Bacterial diseases; Do not spray when the air humidity is too high; Do not spray when the diseases and insect pests are serious in the shed (house). The soaking method is mainly used for bagged edible fungi. After harvesting 1 to 2 tidal 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 near its original weight. The soaking method is used to add the nutrient solution. Generally, the bacterial bag is put into the nutrient solution pool and the heavy object is pressed. And soaking time can not be too long. If the bag has lost too much water, it can be soaked 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 more mushrooms and the water and nutrients are consumed excessively. The specific method is as follows: The bacteria bed is drilled at a distance of 10 cm, and the prepared nutrient solution is flooded into the bacteria bed, and the soil is added after the nutrient solution is added.
2 The concentration should be appropriate. When the concentration of nutrient solution is too high, not only is it difficult to absorb mycelium, but it also hinders or even damages the growth of mycelium; when the concentration is too low, the purpose of high yield cannot be achieved. When the nutrient solution is added at a suitable concentration, it is determined according to the moisture content of the culture material: if the moisture content of the culture material is higher, 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; It should reduce the concentration of nutrient solution and increase water consumption.
3 nutrient solution nutrients should be comprehensive. Several nutrient solutions should often be used interchangeably, so that nutrients required for fruit body growth are comprehensive and reasonable. If hormones are used to stimulate the growth of mushrooms, they should be used after supplementing the nutrient solution.
4 Pay attention to changes in the environment. When the temperature reaches above 20°C, the mycelium is difficult to form a high-quality fruit body, and no nutrient solution can be added except for the high-temperature edible mushroom species. If the culture material has been contaminated with bacteria, be sure to remove the bacteria before adding nutrient solution. In order to prevent bacterial contamination, a certain amount of bacteriostatic agent may also be added at the same time as the nutrient solution is added to prevent the growth of germs.
