How to grow Flammulina velutipes at home

The emergence of balcony vegetables has not only changed the traditional boundaries of vegetable cultivation, but also made it possible for the urban population to grow vegetables, which is undoubtedly a very useful planting method for Chinese people who love to grow vegetables. But after all, the area of the balcony is limited, and the number of Flammulina velutipes planted will not be too much.

How to grow Flammulina velutipes at home

1. Choose a plastic bag to cultivate Flammulina velutipes. First, put the plastic bag in the carton, spread plastic paper and newspaper on the bottom of the box, spray a little water into the bag, and cover it with a transparent plastic bag.

2. After mushroom emergence, put the carton in a place with a room temperature of 10-18 ℃, keep the surrounding air moist, spray water on the newspaper or the surrounding space, and never spray directly on the mushroom surface. At this time, I saw clumps of Flammulina velutipes, which was lovely!

3. Flammulina velutipes at this stage began to grow, with the highest reaching 5 centimeters. The vigorous growth of Flammulina velutipes is 10 centimeters tall and can be harvested.

Cultivation techniques of Flammulina velutipes

1. Making bacterial bags

The production of bacterial bags requires plastic film bags, rings, cotton and so on. Polypropylene should be selected as the film bag for Flammulina velutipes. The specification is 38 cm long and 15-16 cm wide. The thickness of the film bag is 5-6 silk meters, and the quality of the plastic film bag has a great influence on the yield of Flammulina velutipes. Attention should be paid to the inspection of film quality. There are two kinds of rings: plastic rings and cardboard rings. Cotton for cotton stoppers should be exposed to the sun before use and stored in a dry and ventilated place.

2. Mixing material

There are two kinds of mixing materials, organic mixing and manual mixing. Special attention should be paid to mixing all kinds of culture materials and auxiliary materials well, as well as between culture materials and water. The specific practice is to weigh the required amount strictly according to the formula of the culture material. In addition to a small amount of sugar and other excipients soluble in water, dry mix the dry material evenly, and dissolve sugar and other soluble excipients in water at the same time. Diluted in proportion and sprayed on the culture material, spray and mix until the water content is suitable. The theoretical water content of the culture material for the cultivation of Flammulina velutipes is 58-65%, but it should be mastered according to the specific conditions because of the different kinds of culture materials and different dry and wet conditions. Usually check based on experience, the method is to hold the culture material into a ball, fall to the ground and spread out, and it is appropriate to squeeze the culture material tightly with the thumb, index finger and middle finger.

3. Loading

At present, there is no special bagging machine for Flammulina velutipes cultivation in China, and the charging machine can be used for Lentinus edodes sawdust cultivation. The specific operation of manual loading is to put a small amount of culture material into the bag, press the two corners at the bottom of the bag with thumb and index finger, so that the bottom is square so that the bag can stand upright, and then continue loading and compaction. In order to shorten the mycelium culture time, you can put a conical stick about 1 cm in diameter in a plastic bag when loading. After the material is fully compacted, gently rotate to take out the stick. After the material is loaded, put on the ring and plug the cotton plug, and then sterilize. The amount of nourishment accounts for about 3% of the total length of the bag, leaving 15-20 cm at the end of the bag.

4. Sterilization

Flammulina velutipes grass bag cultivation is clinker cultivation, that is, sterilization pot or stove should be used for sterilization. When sterilizing, those sterilized by pressure cooker should be kept for 1.5 hours under the pressure of 1.5kg / cm, and those sterilized by atmospheric furnace should be kept for 10 hours when the temperature of the culture material in the culture bag in the furnace reaches 100 ℃. After sterilization, open the exhaust hole to cool down gradually, and then open the furnace door to get out of the bag.

5. Inoculation

Flammulina velutipes bag inoculation is usually carried out in a sterilized inoculation box. If there is no inoculation box, the inoculation can also be carried out in the inoculation room according to the routine operation of edible fungi. For those vaccinated in the inoculation room, the inoculators should change into clean clothes before entering the inoculation room, and their hands and utensils should be sterilized with 70% alcohol. People should not go in and out until the bacteria are finished. The cultivated species of Flammulina velutipes should be carefully selected. if it is found that the strains with miscellaneous bacteria can not be used, the appropriate age should be less than 1.5 months. When inoculating, the mouth of the plastic bag should be close to the aseptic circle of alcohol lamp flame, and it would be better to inoculate more. A small number of bacteria are connected to the human hole, and most of the bacteria are distributed on the surface of the culture medium, so that each bottle of original seed can be inoculated with about 40 bags.

Distribution of producing area of Flammulina velutipes

Flammulina velutipes is widely distributed in nature, such as China, Japan, Russia, Europe, North America, Australia and so on. It is suitable for the growth of Flammulina velutipes from Heilongjiang in the north, Yunnan in the south, Jiangsu in the east and Xinjiang in the west. Lingshou in Shijiazhuang, Hebei Province, grows a large number of white Flammulina velutipes, which is produced and sold in various places in November and February.

Nutritional value of Flammulina velutipes

1. Flammulina velutipes contains all kinds of essential amino acids, in which lysine and arginine are especially rich, and the content of zinc is relatively high, which plays a good role in enhancing intelligence, especially on children's height and intellectual development.

2. Flammulina velutipes also contains a substance called Psilocybin, which can enhance the body's resistance to cancer cells. Flammulina velutipes can also lower cholesterol, prevent liver diseases and gastrointestinal ulcers, enhance the vital energy of the body, prevent disease and fitness.

3. Flammulina velutipes can effectively enhance the biological activity of the body, promote metabolism in the body, is conducive to the absorption and utilization of various nutrients in food, and is also of great benefit to growth and development, so it has the laudatory name of "wisdom mushroom" and "Yixiu mushroom".

4. Flammulina velutipes can inhibit the increase of blood lipids, reduce cholesterol, and prevent and treat cardiovascular and cerebrovascular diseases.

5. Edible Flammulina velutipes has the effects of anti-fatigue, antibacterial and anti-inflammation, removing heavy metal salts and anti-tumor.

6. Regular consumption of Flammulina velutipes can not only prevent and treat liver diseases and gastrointestinal ulcers, but also suitable for hypertensive patients, obese people and middle-aged and elderly people, mainly because it is a food with high potassium and low sodium.

Although the method of growing Flammulina velutipes at home is very simple, and even the discarded roots of Flammulina velutipes can be used to grow new Flammulina velutipes, at present, the cultivation method that can meet the large-scale demand of Flammulina velutipes is still large-scale cultivation of Flammulina velutipes, so family cultivation is only suitable for personal interests and small needs.
