Auricularia auricula planting technology, selecting trees and cutting trees are all technical work!

Auricularia auricula is now one of the favorite foods for many friends, whether it is cold or in soup, it has a strong sense of existence, crisp and delicious nutritional value. More and more farmers begin to plant Auricularia auricula, because they do not know how to take many detours. Today, the editor will summarize the planting techniques of Auricularia auricula.

Planting technique of Auricularia auricula

1. Select trees

It is very important for Auricularia auricula to choose trees, and there are many trees suitable for it. However, it is necessary to take measures in accordance with local conditions, and select tree species that are rich in local resources and are "easy to grow ears". Except for tree species such as turpentine, essential oils, alcohols, ethers and economic forest trees, other tree species can be planted. At present, the commonly used tree species are Quercus variabilis, Betula platyphylla, Castanopsis carlesii, Maple Poplar, Liquidambar formosana, Elm, Robinia pseudoacacia, Willow, Chaoshu, Fatong, Coptis chinensis and so on. But Quercus variabilis and Quercus variabilis are the best.

2. Cut down trees

The historical habit is to "enter nine" to cut down trees. Generally speaking, trees can be cut down from the withered and yellow leaves to before the new leaves germinate, because this period is the "dormant" period of trees, and the nutrients in the stems are in a state of accumulation and immobility, with less water. Nutrients are most abundant and concentrated, which is called "pulp-harvesting trees". At the same time, the bark and texture of the trees cut down during this period are closely combined, and the bark is not easy to take off after felling, which is conducive to the growth and development of black fungus.

3. Pruning

After the tree is cut down, do not immediately cut branches, retain branches and leaves can accelerate the evaporation of water, make the stem dry quickly, make its cell tissue die, and at the same time help the nutrients on the top of the tree to concentrate on the trunk. Wait for + half a day before picking branches. When picking, it is necessary to use a sharp machete to flatten the tree trunk from bottom to top and cut it into a "copper scar" or "cow eye". It is not possible to cut too deep, injuring the cortex, and the cut scar should be smeared with lime water to prevent miscellaneous bacteria from invading and stagnant water. it's also easy to pile up.

4. Cut off the pole

In order to facilitate the stacking, ostentation, erection, management and harvesting of ear sticks, and to facilitate moisture absorption when the ear sticks are put down, the trunks that are too long should be cut into short sticks 3 feet long. Cut off the head with a hand saw or chainsaw and smear it with lime water to prevent miscellaneous bacteria infection.

5. Inoculation

When the temperature of the special bag drops below 30 degrees, vaccination can be carried out. Inoculation to achieve aseptic operation, 17cm × 33cm bacterial bag inoculation procedure is: put the cooled bacterial bag into the inoculation box; the outer wall of the original bottle is also put into the inoculation box after being wiped and disinfected with 75% alcohol, and then fumigated with 5 grams of potassium permanganate per cubic meter and 10 ml formaldehyde for 0.5 hours. Light the alcohol lamp during inoculation, break the original seed with sterilized tweezers, in the sterile area where the alcohol lamp is lit, make the mouth of the original bottle face the mouth of the bag, and spread the bacteria evenly on the surface of the bag to form a thin layer, so that the mycelium of Auricularia auricula germinates quickly and preemptively occupy the material surface to inhibit miscellaneous bacteria infection. Each bottle of secondary species can receive about 30 bags. The bag inoculation method of 16cm × 52cm was the same as that of Lentinus edodes.

6. Lighting

Auricularia auricula needs enough scattered light and some direct light at the stage of coming out of the ear. Increasing the light intensity and prolonging the light time can enhance the transpiration of the ear piece and promote its metabolic activity. the ear piece becomes thicker, the color becomes black and the quality is good. 400~1000lx is suitable for light intensity. When planting Auricularia auricula in bags, the position of bacterial bags should be changed and turned frequently during the period of ear emergence, so that each bacterial bag can get uniform light and improve the quality of Auricularia auricula.

7. Processing

The harvested fungus should be dried in time. Cut off the culture medium from the root of Auricularia auricula with scissors before drying. The ground-planted black fungus should be washed with clean water to remove impurities, first-class products should be torn into pieces above 2cm in diameter, and second-class products should be torn into pieces above 1cm in diameter and put on screen windows to dry. After drying, the black fungus (water content less than 14%) should be put into a plastic bag in time. Fasten the mouth of the bag to be moistureproof and mothproof.

Note: if the earpiece is not unfolded during harvest, it can not be picked (because there is no commodity value), leave it for the next crop management.

The planting technology of Auricularia auricula is summarized here, it is more troublesome to cultivate, but it is very easy to master the method. You can consult more friends or organizations who have already had cultivation experience, and since you are determined to start planting, you should make all preparations.
