What are the latest varieties of Flammulina velutipes?

The types of artificially cultivated Flammulina velutipes can be divided into early type and late type according to the speed of mushroom production, low temperature type and high temperature type according to the temperature of occurrence, and can be divided into fine type (many stalks) and coarse type (few stalks) according to the number of fruiting bodies. Let's take a look at the varieties of Flammulina velutipes.

Sanming No. 1 strain

The cultivation of Sanming No. 1 strain is very common, the mycelium grows fast, the tube can be full in 7 days, and the mycelium can grow full in bottles or bags in 25-30 days. The mushroom can be produced quickly, it can be produced in more than 30 days, the cultivation period is short, the whole cultivation cycle can be completed in 70-80 days, the yield is high, the biological efficiency can reach 70%-100%, the quality is good, the stalk thickness is uniform, and the color is light. The content of 8 amino acids needed by the human body accounts for 44.5% of the total amino acids, which is higher than that of general mushrooms, and can produce mushrooms at 3-21 ℃. Strong stress resistance, less diseased mushroom and abnormal mushroom.

007 and 008 young mushroom bacteria

The cover is light yellow to yellowish brown, the upper part of the stalk is light, white to light yellow, the lower part is dark, golden to dark brown, densely covered with brown short villi. It has strong stress resistance, fast feeding of mycelium, early mushroom emergence and high yield after inoculation. During the growth of mushroom buds, only weak scattered light (5 ~ 10 lux) was needed, and the color of mushroom body deepened with the increase of light intensity. The thick color strain Flammulina velutipes has soft and smooth cover, crisp stalk and rich flavor, so it is suitable for domestic sale of fresh mushrooms.

White strain F21

The strain of the Institute of Microbiology in Jiangshan City, Zhejiang Province, produces mushrooms neatly, each clump is about 200, the stalk is 15-23 cm long, the cover is rolled up, it is not easy to open the umbrella, and the white strain is not sensitive to light, even if the cultivation environment has strong scattered light, the fruiting body is still white and shiny, suitable for canning or salt processing export.

The mycelial growth of white strain Flammulina velutipes is slow, the stress resistance is poor, and the impurity resistance is weak. When cultivated in bottles and bags, the hyphae are not easy to grow and nourish through culture. The tolerance to carbon dioxide is weak during mushroom emergence. In the environment of poor ventilation, although there are many mushroom buds, but the number of mature mushrooms is small, and the mushroom stalk is easy to be twisted, deformed or rotten. This phenomenon is especially serious in the later stage, so only the first two crops of mushrooms are harvested in production, so the yield is relatively low. White strain Flammulina velutipes mushroom body is white, suitable for processing into export commodities. Because of its light taste, domestic sales are sometimes not as popular as Flammulina velutipes.
