The "five characters" Sutra of Water Management in the period of Mushroom emergence with Golden Needle in bag cultivation

Flammulina velutipes cultivation and management requirements are high, especially the fruiting body development is very sensitive to water requirements, water management in this period is the key to achieve high yield and high quality. This paper introduces the water management method of "five characters" for reference. Ichiguro. When the mycelium is sent to the bottom of the bag, immediately open the bag to scratch the bacteria, rake off the old bacterial skin, cover with wet newspaper or plastic film to moisturize and bud. If the newspaper is covered, it should be sprayed a few times (3 times a day, 4 times a day) to keep the newspaper moist; if covered with plastic film, it can spray water to the ground and space, keeping the air humidity about 90%. In this period, the window was opened and ventilated once a day, the room temperature was controlled at 10 ℃ and 14 min, and a large number of mushroom buds occurred in 7 days. Second drop. When the mushroom bud grows to 1mi 2cm, it enters the growth inhibition period. At this time to reduce or stop spraying water, reduce humidity. Open the doors and windows at night for 5 consecutive days, let the cold air cool and dissipate humidity, lower the room temperature to less than 8 ℃ (4 Mel 5 ℃ is the best), and the humidity is about 75%, so that the fruiting body is restrained and the growth is neat and sturdy. Three urges. The fruiting body grew to 4cm. After entering the extension period, the fruit body was sprayed 4 times per day for 5 times. The amount of spraying water increases as the mushroom grows, and the air humidity is about 90% (that is, fine water droplets are attached to the bag wall at the base of the fruiting body) to promote the rapid growth of the fruiting body. At the same time, proper ventilation and alternation of dry and wet were adopted to inhibit the increase of mushroom cover and promote the elongation of mushroom stalk. According to the weather conditions, the amount of water sprayed at this stage should be properly sprayed more in sunny days and less in rainy days, so as to prevent root rot, brown spot and mushroom body from becoming watery mushrooms due to excessive water use. Do not spray water on the mushroom cover, find that the newspaper is damaged and replace it in time, and pour out the stagnant water on the newspaper immediately to prevent the mushroom body from coming into contact with water droplets to produce black spots and affect the appearance of the goods. Four supplements. After the first tide mushroom was harvested, the water content of the bacterial bag decreased by 20%, 30%, and 30%, respectively. Therefore, after the first and second tide mushrooms are harvested, water should be sprayed into the scratched bacteria bag to moisturize immediately. The method is to spray water directly into the bag 3 times a day for 3 consecutive days, and each time the surface of the bacteria column should be moist, so as not to make the bag accumulate water. In order to increase the yield, a small amount of urea, sugar and potassium dihydrogen phosphate can be added to the water to supplement nutrients. Five dips. After the three tide mushrooms are harvested, the water content of the bacteria column has been reduced to less than 50%. At this time, the plastic bag can be removed, and the bacteria column can be soaked in the pool water (upper weight). When the bacteria column absorbs water and returns to its original weight when opening the bag, it can be slightly dried and put into the bag. The bag can also be soaked with water directly, and the excess water in the bag can be cleaned after the bacteria column absorbs enough water. After replenishing the water, the bacterial bag will be rearranged on the bedstead, and the wet newspaper will be managed as usual, so that two tide mushrooms can be picked.
