How many times a year can Flammulina velutipes grow in the greenhouse? How can cultivation increase production?

Flammulina velutipes is a common fungus in daily life, the market price is not high, and it is widely planted in our country. How many times a year can Flammulina velutipes grow in the greenhouse? How can we increase production by cultivation?

I. the basic situation of Flammulina velutipes

1. The origin of Flammulina velutipes

Golden stock is a kind of fungus for both medicine and food, also known as Pleurotus ostreatus, Zizania latifolia, frozen fungus, Flammulina velutipes, Pleurotus ostreatus, Pleurotus ostreatus and so on. It is widely distributed in China, Japan, Russia, Europe, North America, Australia and other places. It is planted in all parts of the southeast and northwest of China, and even Xinjiang is suitable for the growth of Flammulina velutipes. Therefore, Flammulina velutipes is basically produced all over the country.

two。 The value of Flammulina velutipes

Flammulina velutipes is rich in vitamins, amino acids and minerals, which can reduce cholesterol content, relieve fatigue, inhibit cancer cells and improve body immunity. It has a certain auxiliary effect in the treatment of liver disease, gastrointestinal inflammation, ulcer, tumor and other diseases.

3. Yield per mu of Flammulina velutipes

Generally speaking, Flammulina velutipes can be cultivated in about 10, 000 bags per mu, and the yield can reach 8000-10000 kg, but the yield is linked to production management technology, so good management technology is the key to increase production.

Second, how many times a year can Flammulina velutipes grow in the greenhouse?

Flammulina velutipes is generally cultivated once a year, and it can be ripe three times a year. It is cultivated in September every year. The two-tide mushrooms are harvested and listed before the Spring Festival, and the harvest ends in mid-February of the following year.

Third, how to increase production by planting Flammulina velutipes in greenhouse?

We all know that the cultivation technology of Flammulina velutipes is not difficult, but the difficulty is how to increase its production. Here are several methods and techniques for your reference.

1. Narrow bag cultivation of Flammulina velutipes

Generally speaking, Flammulina velutipes is cultivated in wide bags, but in fact, it is easier to be infected with miscellaneous bacteria, thus affecting the quality. Therefore, if you want to increase production, it is better to cultivate plastic bags of 17cm × 33cm. In addition, if the mycelium in the bag grows slowly, unpack the bag in time, but don't untie it all, and then straighten the bag at one time when the mushroom stalk grows to about 8 centimeters.

two。 Flammulina velutipes sterilized by delayed atmospheric pressure

Flammulina velutipes grows rapidly on rich culture materials, and it is easy to decompose quickly when it is more than 120 ℃, so it is better to sterilize under normal pressure. However, in order to ensure the pure bacteria rate of Flammulina velutipes, the sterilization time is usually extended from 10-12 hours to 13-18 hours.

3. Flammulina velutipes adopts the horizontal method of producing mushrooms at both ends.

When loading, inoculate at both ends and leave about 15 cm of cylinder film, light and uniform pressure, fasten the mouth of the bag. Put about 4 layers of bacteria horizontally. This method can not only ensure the quality of mushroom production, but also save the area of mushroom room, and increase the output of mushroom house by more than 30% per square meter.

4. The growth of Flammulina velutipes induced by red light

Because of the phototaxis of Flammulina velutipes, red light bulbs can be hoisted every 4 meters or so after they are on the shelf, which can induce them to grow horizontally toward the light source and promote the extension of the mushroom body; at the same time, shading should be done in other places.

These are all the contents introduced by the editor of Tuliu.com. You can also try to cultivate Flammulina velutipes at home. Basically, Flammulina velutipes can be planted all the year round, but Flammulina velutipes will grow faster in spring and autumn.
