First, we must pay attention to the method of adding nutrient solution is usually added in three ways: spray, soaking, and cavitation. It is advisable to spray the nutrient solution in large amounts in the fruit body. Spraying should pay attention to the nozzle is not facing the fruiting body, while paying attention to the "four does not spray": 1. Young mushroom buds do not spray, so as not to "swollen"; 2. Freshly picked mushrooms or mushroom residues Do not spray, so as not to cause bacterial diseases; 3. Do not spray when the air humidity is high; 4. Do not spray when the pests and diseases in the mushroom shed are serious. The soaking method is mainly used for bagged edible fungi. After harvesting 1-2 oyster mushrooms, the cultivation bag will be in a state of water shortage, and the bacterium bag can be soaked in the configured nutrient solution. The length of immersion time is preferably 80% of the original weight. The irrigation method is mainly used on the bed cultivation method. The method is: on the bed of bacteria, the hole is drilled at a distance of 10 centimeters, and the prepared nutrient solution is filled into the hole.
Second, the concentration of the nutrient solution should be too high, it will cause the absorption of mycelium is difficult, and even cause mycelial damage; concentration is too low, the effect is not obvious. Under normal circumstances, the concentration of nutrient solution should be controlled at 1-1.5%.
Third, nutrient solution nutrients should be used to fully complement the nutrient solution should be used interchangeably with several kinds of nutrient solution, so that the nutrition needed for fruit body growth will be comprehensive and reasonable.
