In the cultivation of edible fungi, water plays a role in providing nutrients for the mycelium and the mushroom body, and is an important factor in determining the level of yield and fast turning. Most varieties of culture materials have a suitable moisture content of 60% to 65%. During the fruiting process, the moisture of the culture materials and space is gradually reduced, and it needs to be supplemented in time. The following points should be noted when replenishing the culture medium of the bacterial bag:
1, replenishment time and amount of water: mushrooms and other color conversion is completed, before the mushroom will have to pay water, make up the culture material moisture content of about 65%. After harvesting the first tidal mushroom, most edible fungi have abundant nutrients in the substrate, higher moisture content in the matrix, and less water recharge. When the second tidal mushroom grows, the nutrition of the substrate decreases, and the moisture in the substrate also decreases. The amount of water can be more, and the time for the bag to soak can be longer. When replenishing water, it is necessary to keep the bacteria first, then replenish the water, and the amount of replenishment should be controlled within 80%-90% of the weight of the original bacteria bags. Hyphae sparse, weak growth, temperature below 5 °C or material pests and diseases should not make water. After the three tide mushrooms replenish water, they can also add nutrients, commonly used urea, sugar, potassium dihydrogen phosphate and so on.
2. Apply clean river or groundwater when replenishing water: It is not appropriate to use surface pond water and ditch water to prevent bacteria and pests from being carried into the matrix, causing pests and diseases.
3, the water temperature is as consistent with the mushroom shed temperature, do not use cold water: the original base, mushroom buds do not spray. It is best to use a sprayer to make up the water, and spray the nozzle upwards to the space to humidify it.
4, after replenishment: If there is water on the mushroom body should be ventilated and removed, otherwise it will give the bacteria breeding opportunities, the formation of lesions in the mushroom body.
