The method of adding nutrient solution to science to provide nutritional supplements to edible fungi include spraying, soaking and irrigating. Spraying is used for a large number of fruit body development periods. The commonly used method is to formulate a certain concentration of nutrient solution, combined with replenishment, and spray on the bacteria bed and the bacteria block. Spraying nutrient solution is best done at low tide. Pay attention to the nozzle when spraying, not facing the fruiting body. At the same time pay attention to four do not spray: young mushroom buds do not spray, just picking mushrooms or mushroom residues are not sprayed, the air humidity is not sprayed, the mushroom shed is not serious when the pest. Soaking is mainly used for bag planting or block planting methods. After harvesting 1~2 oyster mushrooms, if the bacterium bag (block) is seriously deficient in water, soak the bag or block in the well-matched nutrient solution, but the soaking time should not be too long. If there is too much water, it can be divided into several Submersion. The burrowing hole is mainly used in the bed of bacteria, and when the mushroom bed has more mushrooms and nutrient consumption is too large, it is used. The method is to open the soil on the bed of bacteria, and insert a funnel into the material surface to fill the liquid with 4 to 7 ml, and the distance between the points is 10 cm. After the liquid is added, the soil is covered.
The concentration of the nutrient solution to be added to the nutrient solution is too high, which will prevent the growth of the mycelia; if the concentration is too low, the effect of increasing the yield is not obvious. In the appropriate concentration, when added, it should be based on the humidity within the material. If the humidity of the culture material is too high, the concentration of the nutrient solution may be appropriately increased to reduce the amount of water, and after the supplement of the nutrient solution, the ventilation may be enhanced, and on the contrary, the concentration may be reduced to increase the amount of water.
Adding nutrient solution should pay attention to environmental changes in general when the temperature is higher than 20 °C, mushroom mycelia is difficult to form fruiting bodies, should stop rehydration, glucose solution, soy milk juice, human waste, urine should not be more than 18 °C when the temperature above rehydration , It is also possible to add an appropriate amount of bacteriostatic agent in the nutrient solution to prevent the spread of germs.
Alternate supplementation of different nutrient fluids Several nutrient fluids are alternately used or mixed to meet the requirements of different nutrients for edible fungi. Normally nutrient solution supplemented with nutrients is applied first, and then high-efficiency nutrient solution is applied. If hormones are used to stimulate the growth of edible fungi, they should be supplemented with nutrients and hormones.
Correct application of manure compost and excrement must be thoroughly fermented and decomposed or sterilized by high temperature. The use of plant extracts such as soybean milk and potato juice should be used immediately.
