The time of spraying the nutrient solution is suitable when a large number of fruit bodies are present. When spraying, it should be noted that the sprinkler should not be facing the fruiting body, but also pay attention to "four do not spray": 1. Young mushroom buds are not sprayed to prevent their "swelling." 2. Just after the mushroom or mushroom residue is not sprayed, so as not to cause bacterial disease. 3. Do not spray when the air humidity is too high. 4. Mushroom (house) does not spray when serious pests and diseases.
The soaking method is mainly used for bagged edible fungi. After harvesting l~2 oyster mushrooms, if the growing bag is in a state of severe water shortage, it can be soaked in a prepared nutrient solution until it recovers or approaches its original weight.
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 cm, and the prepared nutrient solution is flooded into the bacteria bed, and the soil is added after the nutrient solution is added.
When the concentration of an appropriate nutrient solution is too high, not only is mycelial absorption difficult, but it also impedes or even damages the hyphae. When the concentration is too low, the purpose of high yield cannot be achieved. If the moisture content of the culture material is high, the concentration should be increased. After adding the nutrient solution, increase the ventilation. Conversely, the concentration of nutrient solution should be reduced to increase the amount of water used. The commonly used nutrient solution concentration is: urea 0. 3% ~ 0. 5%, potassium dihydrogen phosphate 0.2%, etc., we must grasp the "less and diligent" principle.
Nutrients should be used interchangeably in several nutrient solutions, so that the nutrition obtained by the fruiting bodies is comprehensive and reasonable. If hormones are used to stimulate the growth of mushrooms, they should be used after supplementing the nutrient solution.
Environmental changes When the temperature reaches 20°C or more, nutrient solutions may not be added except for 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.
Nuts are a group of cleistoses that have a hard skin and contain a single seed. It is the essence of plants, rich in nutrition, containing higher minerals, vitamins, oil and protein, eating more can promote growth and development, increase physical fitness. Common nuts include walnuts, peanuts, almonds, cashews, macadamia nuts, pistachio nuts and so on.
