Flammulina velutipes moisture management method
Yibao. When the mycelium reaches the bottom of the bag, immediately open the bag to scratch the bacteria, rake off the old mycelium, cover with wet newspaper or mulch to moisturize and promote buds. If the newspaper is concealed, spray water a few times 3-4 times a day) to keep the newspaper moist; if the mulch is covered, spray water on the ground and the space to keep the air humidity around 90%. During this period, the window was opened for ventilation once a day, and the room temperature was controlled at 10-14°C. After 5-7 days, many mushroom buds would develop.
Second drop. When the mushroom bud grows to 1-2 cm, it enters the suppressed growth period. At this moment, reduce or stop the water spray and reduce the humidity. Open the doors and windows at night for 3-5 consecutive days, let the cool breeze enter to cool down the humidity, lower the room temperature to below 8°C (at 4-5°C******), and the humidity to about 75%, so that the fruit body is inhibited , The growth is regular and robust.
Three promotion. The fruit body grows to 3-4 centimeters. After entering the elongation time, spray water 4-5 times a day. The amount of spraying water is added as the mushroom grows, and the air humidity should be controlled at about 90% (that is, the base of the fruit body has fine water beads attached to the wall of the fruit body) to promote the fruit body to grow rapidly. Properly ventilate at the same time, adopt dry and wet replacement to press the mushroom cover to add and promote the extension of the mushroom stem. The amount of water sprayed at this stage should be determined according to the climate. Spray more on sunny days and less spray on rainy days to prevent root rot, brown spot, and excessive moisture in the mushroom body from degrading quality due to excessive water. Do not spray water on the mushroom cover. If the newspaper is damaged, replace it in time. If there is water on the newspaper, discard it immediately to avoid the black mottle caused by the mushroom body touching the water droplet, which affects the appearance of the product.
Four complements. After the mushroom bag is harvested, the water content of the first tide mushroom decreases by 20-30%, and the second tide mushroom decreases by 30-50% after harvest. Therefore, after the first and second tide mushrooms are harvested, water should be sprayed into the bacteria bag immediately after scratching. The method is: spray water directly into the bag 2-3 times a day for 2 to 3 consecutive days. It is advisable to moisten the surface of the bacterial column each time, and do not allow water to accumulate in the bag. In order to increase the output value, a small amount of urea, sugar, potassium dihydrogen phosphate, etc. can be added to the water to make up for the nutrients.
Five dips. After harvesting the Sanchao mushroom, the water content of the bacteria column has dropped below 50%. At this moment, you can take off the plastic bag, soak the bacteria column in the pool water, and pick it up when the bacteria column absorbs water and recovers to the original weight when the bag was opened. Dry a little and put it into a bag. You can also directly pour water into the bag for soaking, and pour out the remaining water in the bag after the bacteria column has absorbed enough water. After replenishing the water, discharge the bacteria bag on the bed frame from the beginning, cover with wet newspaper and manage as usual, so that two tide mushrooms can be picked.
