Key points of Water Management in Flammulina velutipes cultivation

Flammulina velutiper (Fr.) Sing。Because of its slender stalk, like day lily, it is called Flammulina velutipes, belonging to Agaricales, white mushroom family Flammulina velutipes, is a kind of algae lichen. Flammulina velutipes has a high medicinal dietotherapy effect.

Morphological Characteristics of Flammulina velutipes

Flammulina velutipes consists of two parts: vegetative organ (mycelium) and reproductive organ (fruiting body).

Mycelia germinated from spores. Under artificial culture conditions, hyphae were usually white velvety, with septa and branches. Many hyphae gathered together to form hyphae. Different from other edible fungi, hyphae grow to a certain stage and form a large number of unicellular pollen spores (also called conidia), which can germinate into monokaryotic hyphae or binucleate hyphae under suitable conditions. Some people found in the experiment that the number of powder spores in the hypha stage of Flammulina velutipes is related to the quality of Flammulina velutipes. The quality of the strains with more powder spores is poor, and the color of the base of the stipe is darker.

(2) The main function of the fruiting body is to produce spores and reproduce offspring. The fruiting body of Flammulina velutipes consists of three parts: cap, pleat and stipe. Most of them grow in bundles, and the flesh is soft and elastic. The cap is spherical or flat hemispherical, 1.5~7 cm in diameter, spherical when young, gradually spreading, and folded upward when over-mature. The surface of the cap has a thin layer of colloid, sticky when wet, yellow and white to yellow brown, white flesh, thick center, thin edge, white or ivory pleats, sparse, different lengths, separated or curved from the stipe. The stipe is central, hollow cylindrical, slightly curved, 3.5~15 cm long, 0.3~1.5 cm in diameter, connected at the base of the stipe, fleshy at the upper part (there are also books saying that the stipe is fibrous and gelatinous), leathery at the lower part, densely black-brown short villi on the surface, basidiospores are born on the pleat fruiting layer, spores are cylindrical and colorless.

Water Management in Flammulina velutipes Cultivation

Flammulina velutipes cultivation and management requirements are high, especially the fruiting body development of water requirements. This paper introduces the "five characters" by water management method for reference. Ichiho. When hyphae hair to the bottom of the bag, immediately open the bag scratch bacteria, rake to the old fungus skin, cover wet newspaper or plastic film moisture bud. Newspaper cover, water spray should be a small number of times 3-4 times a day), in order to keep the newspaper wet; plastic film cover, can spray water to the ground and space, keep the air humidity about 90%. During this period, open the window once a day for ventilation, control the room temperature at 10-14℃, and a large number of mushroom buds will occur after 5-7 days. Two drops. When the mushroom bud grows to 1-2 cm, it enters the growth inhibition period. At this point to reduce or stop spraying water, reduce humidity. Open the doors and windows at night for 3-5 consecutive days, let the cold air enter to cool down and dissipate humidity, reduce the room temperature to below 8℃ (preferably 4-5℃), and reduce the humidity to about 75%, so that the fruiting body is suppressed and grows neatly and robustly. Three urges. The fruit body grows to 3-4 cm. After entering the elongation period, water is sprayed 4-5 times a day. Water spray amount increases with mushroom growth, control air humidity at about 90%(that is, the base of the fruiting body bag wall with fine water droplets is appropriate), promote rapid growth of fruiting bodies. At the same time, proper ventilation and alternate drying and wetting were adopted to inhibit the increase of mushroom cover and promote the elongation of mushroom stem. The amount of water sprayed at this stage should be determined according to the weather. Spray more in sunny days and less in rainy days to prevent root rot, brown spot disease and excessive water content of mushroom body from reducing quality due to excessive water consumption. Do not spray water on the mushroom cover, replace the newspaper in time if it is damaged, and pour away the accumulated water on the newspaper immediately to prevent the mushroom body from contacting the water droplets to produce black spots, which will affect the appearance of the commodity. Four supplements. After harvesting, the water content of the mushroom bag decreased by 20-30%, and the second tide mushroom decreased by 30 - 50%. Therefore, after the first and second tide mushrooms are harvested, water should be sprayed into the bacteria bags immediately after scratching. Its practice is: continuous 2-3 days, 2-3 times a day directly towards the bag spray water, each time to the surface of the bacteria column wet is appropriate, do not make the bag water. In order to increase yield, a small amount of urea, white sugar, potassium dihydrogen phosphate, etc. can be added to the water to supplement nutrients. Five dips. After harvesting three tide mushrooms, the moisture content of the bacterial column has dropped to less than 50%. At this time, the plastic bag can be removed, and the bacterial column can be soaked in pool water. When the bacterial column absorbs water and recovers to the original weight when the bag is opened, it can be picked up, dried slightly and put into the bag. You can also directly pour water into the bag to soak, wait for the bacteria column to absorb enough water, and then pour out the excess water in the bag. Make up moisture and then re-discharge the bacteria bag on the bed frame, cover wet newspaper as usual management, so you can also pick two tide mushrooms.
