The cultivation and management requirements of Flammulina velutipes are high, especially the water requirement of fruit body development. The five-character water management method is now introduced for reference.
One guarantee. When the hyphae is sent to the bottom of the bag, immediately open the bag of bacteria, remove the old fungus, cover the wet newspaper or the film to moisturize and bud. Newspapers covered, spray water should be a small number of times 3-4 times a day), in order to keep the newspaper moist; the film cover, can spray water to the ground and space, to maintain air humidity of about 90%. In this period, the window is ventilated once a day, and the room temperature is controlled at 10-14 °C. After 5-7 days, the mushroom buds will occur in large quantities.
Two drops. When the mushroom bud grows to 1-2 cm, it enters the period of inhibition growth. At this time, reduce or stop the water spray and reduce the humidity. Open the doors and windows for 3-5 days in a row, let the cold air enter the cooling and dehumidification, reduce the room temperature to below 8 °C (best at 4-5 °C), and reduce the humidity to about 75%, so that the fruit body is suppressed and grows neatly and sturdy.
Three promotion. The fruiting body grows to 3-4 cm, and after entering the elongation period, it sprays water 4-5 times a day. The amount of water spray increases with the growth of the mushroom, and the air humidity is about 90% (that is, the water droplets on the base of the fruit body are attached), which promotes the rapid growth of the fruit body. At the same time, proper ventilation, alternating dry and wet to inhibit the increase of mushroom cover and the elongation of the mushroom handle. The amount of water sprayed at this stage should be determined according to the weather. It should be sprayed on sunny days and sprayed less on rainy days to prevent root rot, brown spot and excessive water in the mushroom body from degrading due to excessive water consumption. Do not spray water on the mushroom cover. If the newspaper is damaged, it should be replaced in time. The water in the newspaper should be poured off immediately to prevent the contact of the mushroom body with black spots and affect the appearance of the product.
Four supplements. After the fungus bag is harvested, the water content drops by 20-30%, and the second wave mushroom drops 30-50% after harvest. Therefore, after harvesting the first and second tidal mushrooms, spray the water into the bacteria bag after the sputum. The method is as follows: 2-3 days in a row, 2-3 times a day, spray water directly into the bag, and it is better to wet the surface of the column every time, so that no water can be accumulated in the bag. In order to increase the yield, a small amount of urea, sugar, potassium dihydrogen phosphate, etc. may be added to the water to supplement the nutrients.
Five dips. After harvesting the three tide mushrooms, the water content of the bacteria column has dropped below 50%. At this time, the plastic bag can be taken off, and the bacteria column is immersed in the pool water, and the water is recovered when the water is restored to the original bag opening weight. , dry it slightly into the bag. It is also possible to directly inject water into the bag and soak the water in the bag after the column has absorbed enough water. After replenishing the water, the bag will be re-discharged on the bed frame, and the wet newspaper will be managed as usual, so that two mushroomes can be taken.
