Pleurotus ostreatus, Pleurotus ostreatus, and other edible fungi are common foods in daily life. Their taste is crisp and nutritious. They are highly favored by consumers and have high planting value. In order to enhance the stamina potential and increase the yield benefits of mushroom cultivation, fertilization of edible fungi will be performed in the late stage of fruiting. However, if fertilization is improper, it is easy to backfire. Therefore, it is very important to grasp the fertilization and top dressing technology of edible fungi. The most important thing is to master "two suits and two requirements." The main points of fertilizing and fertilizer management techniques for edible fungi are described below.
First, the addition method should be suitable
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 not spray": young mushroom buds do not spray, so as not to "swollen"; just picking mushrooms or mushrooms residue body is not sprayed, 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 1-2 tidal mushrooms, if the growing 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. 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 the soaking time cannot 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 to drill the bacteria bed at a distance of 10 centimeters from the hole and fertilize the prepared nutrient solution to the bacteria bed, and add the nutrient solution to cover the soil.
Second, add 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. The concentration of nutrient solution to be added depends on the moisture content of the culture material: if the moisture content of the culture material is high, the concentration of the nutrient solution should be increased to reduce the amount of water, and the amount of ventilation should be increased after the addition; otherwise, the nutrient solution should be reduced. The concentration increases the amount of water used.
Third, nutrition nutrient should be comprehensive
Several nutrient solutions should often be used interchangeably, so that the nutrients needed for fruit body growth will be comprehensive and reasonable. If hormones are used to stimulate the growth of mushrooms, they should be done after supplementing the nutrient solution.
Fourth, 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.
