How to cultivate Flammulina velutipes?

How to cultivate Flammulina velutipes? What do you need to pay attention to? Also ask experienced netizens to help introduce the large amount of Flammulina velutipes planted in China, which is also the first choice of daily edible strains. The cultivation methods of Flammulina velutipes are sorted out in the field network, which are listed below for netizens' reference. The selection of mother species of Flammulina velutipes: the yield of Flammulina velutipes is high or low, which has a great relationship with the quality of the introduced mother species. The hyphae of normal mother species should grow neatly, showing light white or thick white, and the hyphae should be white and slender when they are full. When preserving the mother seed, you should put it in the refrigerator when the mycelium is almost full, and do not wait for the mother mycelium to be completely full before cryopreservation. If the mother seed is preserved at low temperature after the mycelium of the mother seed is completely full, it is very easy to make the mother seed bud rapidly in the low temperature environment, resulting in the mother seed losing its use value. The mother seed without budding should be selected when propagating the mother seed. If the mother seed shows bud, the small mushroom bud without umbrella opening should be selected, and the mother seed that opens the umbrella completely should be firmly abandoned, otherwise the yield of Flammulina velutipes may be greatly reduced. Disinfection and sterilization of Flammulina velutipes: the original species of Flammulina velutipes can be sterilized under high pressure and atmospheric pressure. Pressure cooker is generally used in high pressure sterilization, and many mushroom farmers have misunderstandings in high pressure sterilization, thinking that the higher the pressure, the longer the sterilization time, the better. In fact, the key to high-pressure sterilization lies in whether the cold air in the pot is exhausted. The correct way is to open the air release valve of the pressure cooker at the beginning of heating, wait for a large amount of boiling hot gas in the pot to be discharged from the air release valve, maintain the small pot for 10-15 minutes, and the larger pot for 20-30 minutes, and then close the vent valve. it will take 90 minutes to reach the requirement when it rises to 1.5 pressure. At present, atmospheric pressure sterilization is a common method adopted by mushroom farmers, if glass bottles are used to make bacteria, the time of sterilization can be slightly shorter, if plastic bags are used to make bacteria, and there is no compartment in the atmospheric pressure pot, then the time of sterilization should be appropriately extended, and the general principle is that the time would rather be long than short. Identification of Flammulina velutipes strains: the quality of the original species is generally judged from the hyphae, the good quality of the original hyphae is white, the aerial hyphae are obvious, and there is obvious mushroom flavor after opening. If there is a peculiar smell after opening, the mycelium is yellow and white atrophied, it should be firmly discarded. In the season of low temperature, some original species may have mushroom buds on the surface. There is no problem with the quality of these original species and can continue to be used. If corn kernels are used as the original seed, the phenomenon of popping may occur on the top and side of the original seed. Experience has proved that this original seed is generally a good original seed with high and stable yield, so it can be used boldly. The classification and selection of Flammulina velutipes strains: the mother seed is the first class species, the strain propagated by the mother seed is the second class original seed, and the strain propagated by the second class original seed is called the third class production species. Experience has proved that the production of Flammulina velutipes by direct inoculation with the second primary seed propagated by the first-class mother seed has the advantages of good mycelium development, high success rate and low pollution rate. However, the performance of Flammulina velutipes produced by inoculation with three-level production seeds is obviously lower than that of the former. The first reason is that the purification degree of the primary mother seed is very high, the bacterial age is very short, it can grow in about 10 days, there is no recessive pollution, there is no aging, the age of the second primary strain inoculated with it is the same, and then inoculated to produce Flammulina velutipes, the effect is naturally very good. Second, when the secondary original species are re-inoculated with tertiary production species, if the selection is not strict, it is very likely to select bacteria with recessive contamination, which is very likely to cause the expansion of bacterial pollution and seriously affect the yield of Flammulina velutipes. Therefore, it is suggested that the majority of mushroom farmers should adopt the method of secondary original seed inoculation production.
