Water in the bag is a technical measure to increase the yield and quality of Pleurotus ostreatus. Which bags should be replenished? First, look at the growth of mycelium. That is, the mycelium in the material grows vigorously, densely and completely white. The second is to look at the moisture content of the culture material, that is, the bacterial bag whose water content has dropped significantly (below 50%). The third is that the natural temperature is stable above 8°C. All those who meet the above conditions can pay 1 to 3 times of water within the fruiting period. The first replenishment time was the completion of the first tidal mushroom picking, and the second time was the end of 3 tidal mushroom. If the internal hyphae grow weakly, the mycelium is yellow, the viability is decreased, or the moisture in the material is moderate, or the natural temperature drops below 5°C, or pests and diseases have occurred in the material, no water shall be added.
Method for filling water in the bag: After harvesting the mushroom with the mushroom head, use one or more special water supply devices to connect the common sprayer's fittings, switches and other components with a plastic tube or rubber tube. One end is connected to the tap (the tap water pump can be used instead of tap water). First turn on the water tap switch, insert the water replenishment device into the material, and then open the standby switch on the water pipe, and the water will smoothly fill the material under pressure. After a bag is made up, close the switch on hand and fill in another bag. The supplemental standard of moisture is to make the quality of the fungus tube reach the bagging quality or slightly higher. Normally, 1000 grams of dried fungus should be used, and the quality of the water should be 2500 grams. After replenishing water, it can continuously produce 2-3 high-quality oyster mushrooms, and the total output can be increased by 50% compared with conventional mushrooming methods. If it fails to make up the water in the early period, after harvesting 3 to 4 shiitake mushrooms, as long as the mycelium in the material grows vigorously and the natural temperature is above 10°C, it is still possible to make up the water once, but the amount of water supply should be reduced by 20% to 30%. ~ 2 tide good mushrooms. The replenishment method is not available during the hot season so as not to cause overall pollution.
