Three different planting techniques of Tremella fuciformis

Tremella fuciformis, also known as Tremella fuciformis, Tremella fuciformis and Tremella fuciformis Tremella fuciformis Berk. The fruiting body is used as a fruiting body in medicine. It is a precious medicinal fungus. Harvest in spring and autumn, soak lard with old spotted bamboo to make bamboo knife, wash fresh Tremella with clean water and dry it. Tremella tastes sweet, light, flat and non-toxic, which not only has the effect of tonifying spleen and appetizer, but also has the effect of tonifying qi and clearing intestines, nourishing yin and moistening lungs. It can not only enhance human immunity, but also enhance the tolerance of tumor patients to radiotherapy and chemotherapy. There are more than 60 kinds of Tremella in the world, and China is the main producing country, with an annual output of about 100000 tons. The artificial cultivation technology in China began in Tongxian County, Sichuan Province, so it has the title of Sichuan ear and is the earliest country in the world to cultivate Tremella fuciformis. China has been artificially cultivated since 1894, and you are more than 100 years away from now. Now there are cultivation bases all over the country. Among them, Gutian County, Fujian Province has the largest output. About half of the national output.

Tremella fuciformis is also a valuable edible and medicinal bacteria with high economic value. Rich in nutrition, protein contains 17 kinds of amino acids, as well as cellulose, inorganic salts, vitamins and other nutrients. Tremella fuciformis has a delicate shape, elegant color and high nutritional and nourishing value, so it has always been regarded as a delicacy on the table. So, can Tremella fuciformis be planted in several ways? What kind of techniques do you need to master for different planting methods?

(1) the cultivation techniques of Tremella fuciformis are mainly cultivated by three planting methods: basswood, plastic bags and bottle planting.

First, Linden cultivation

1. Duan Mu preparation

Due to the amount of nutrients contained in various tree species and whether the physical and chemical properties of wood can meet the requirements of infants are different. Therefore, the emergence rate of Tremella fuciformis. There is also a big difference in output and quality.

In addition, due to the different natural and climatic conditions, the species and number of trees are also different. therefore, before the cultivation of Tremella fuciformis, the resources of ear trees in this area must be investigated in detail.

A good ear tree should have three conditions:

The main results are as follows: (1) developed sapwood, small heartwood and loose material, directly in 5-10 cm and 3-5 years old.

(2) the thickness of bark is moderate and it is not easy to fall off in the early stage of cultivation.

(3) it is not easy to breed miscellaneous bacteria.

There are actually many species that can be used to cultivate Tremella fuciformis: Maple, black cypress, willow, peach, apple, French sycamore, acacia, poplar and so on.

In addition, pine, fir, cypress, camphor and other tree species containing pine ether, alcohol and other germicidal substances and aromatic positions are not suitable for the cultivation of Tremella fuciformis.

The suitable felling period for ear trees is from defoliation to new buds. During this period, the trees officially entered the winter dormancy period, with rich nutrition accumulation, precise marriage of bark and xylem, especially about 15 days before ear tree germination, the sap began to flow and the content of soluble sugar was high, so it was the most suitable time to cut down.

After the ear tree is cut down, it is sawed into a piece of wood about 1 meter long, and the other side is in a ventilated and dry place to prevent the spread of water and infection.

two。 Suitable for market vaccination

The inoculation of Duanmu should be carried out above 15 degrees, and the inoculation in spring is generally between March and April: in autumn, it is better from October to early November.

Duanmu should be treated before inoculation. First of all, check the water content of the wood. Then to carry out sterilization treatment, the wood row on the ground for "sunbathing", the use of sunlight to kill the miscellaneous bacteria on the surface of the wood. It can also be coated with lime water or copper sulfate on the cross sections at both ends of the wood.

When inoculating, first use belt flushing, electric drill or hand drill to hit the inoculation hole in the section of wood.

After making the hole, take the bacteria out of the bottle, put one in each hole and gently hit it with a hammer.

3. Upper pile of bacteria

In order to promote the strain to develop earlier, maintain good heat preservation and manage in a moisturizing environment, it is generally in the form of a pile of bacteria.

On the pile of bacteria, to choose to avoid the wind to the sun, convenient drainage, clean and sanitary places will be stacked according to the well-shaped regular arrangement, the four corners of the landing should be covered with 10-15 cm bricks, about 1.5 cm high, after stacking, seal the whole pile from top to bottom with plastic film, and then cover the grass curtain or branches on the film. Finally, the cover is fixed and tied with a rope.

The change of temperature should be observed after the reactor, and the temperature in the reactor should be kept at 24-27 degrees. The inner wall of the film is usually covered with water droplets, indicating moderate gentleness.

Under suitable growth conditions, white feathery hyphae can be seen three to five days after inoculation to restore the rope and implant into the wood, which is the sign of the survival of the feather ash mycelium.

4. Turn over the pile and homogenize the bacteria

Due to the different microclimatic conditions in the upper and lower parts of the pile, inside and outside, the germ situation between the sections of wood is also different. in order to promote the germ balance, the rope needs to be turned over.

Turn the pile for the first time and take place 7-10 days after the pile, and then turn every seven days, and turn every 3-4 days before leaving. The whole infection time was 45-50 days, and the pile was turned over for 6-7 times. Adjust the temperature at any time when turning the heap.

5. Show off and make a sound.

When the mycelium in Duan wood develops to a certain stage, it will be transferred to reproductive growth, and the primordium of Tremella fuciformis begins to differentiate and form in the hole, which is necessary to transplant Duan wood out of the ear field and show off.

There are multiple forms of ostentation, such as indoor, tunnel, tree growth, shade shed, air-raid shelter and so on. The commonly used forms are tunnel and indoor.

Tunnel cultivation: tunnel cultivation should be dug in the back Phoenix to the sun, convenient drainage, ventilation and shade place, its specification is very 2-3 meters, pit bottom 2 meters, pit length according to local conditions. A drain is dug under the pit, and a shade is built on the pit to keep out the wind and rain.

Indoor cultivation: that is to say, the ear is grown by putting the wood into a house with ventilation, heat preservation and moisturizing, and clean tattoos. Discharge form, can be erected on the four walls, can also be separated from the shelf. The advantages of indoor cultivation are labor-saving and time-saving, easy to manage, and the disadvantage is that it is not easy to keep warm and humid.

6. Management to increase ears

In the ear-out stage, we should pay attention to the convenient management of temperature, humidity, air and so on. If the weather is muggy, do a good job of cooling. Miscellaneous bacteria are found on the ears and eyes, which can be moved outside the field, washed with 5% lime water, dried in the sun, and then moved back to the distance. If rotten ears are found, they should be dug up in time. After each batch of Tremella fuciformis is finished, stop spraying water for 5-7 days to restore the mycelium and grow the next batch of fruiting bodies.
