(1) Tree selection: There are many tree species suitable for the growth and development of auricularia auricula.

However, it is necessary to adapt to local conditions and choose tree species rich in local resources and easy to grow spikes. In addition to turpentine, essential oil, alcohol ether and other tree species and economic forests, other tree species can plant spikes.

At present, the commonly used tree species are Quercus variabilis, Quercus acutissima, Betula alnoides, Castanopsis carlesii, Pterocarya stenoptera, Liquidambar formosana, Ulmus pumila, Robinia pseudoacacia, Willow, Giant Tree, Paulownia, Coptis chinensis and so on.

But Quercus variabilis and Quercus acutissima are the best.

(2) Cutting down trees: The historical habit is to cut down trees in nine seasons. -Generally speaking, cutting trees can be carried out during the period from the yellowing of leaves to the germination of new leaves, because this period is the dormant period of trees, and the nutrients in the trunk are in a state of accumulation and immobility, with less water and the most abundant and concentrated nutrients. This is called cutting down pulp trees.

At the same time, the bark of trees cut down in this period is closely combined with cytoplasm, and the bark is not easy to fall off after cutting, which is beneficial to the growth and development of black ear.

The age of the cut trees is 7-8 years on sunny slopes, and 8- 10 years on shady slopes or places with poor soil quality. The thickness of the stem is the best, and the length is 1 m.

-50.

Cultivation and management techniques of auricularia auricula

Cutting method requires low stubble, which is higher than the ground 10 ~ 15 cm.

When the axe is cut off from both sides of the trunk, it will leave stubble, which is beneficial to the regeneration of old stumps, and will not accumulate water and rot buds, nor will it affect the regeneration of stumps.

It is beneficial to protect young trees to advocate picking stubble instead of sweeping stubble when logging.

ㄡ Conducive to soil and water conservation.

(3) Pruning: Don't prune the branches immediately after the tree is cut down. Preserving branches and leaves can accelerate the evaporation of water in the tree, promote the rapid drying of the trunk, make its cell tissue die, and help the nutrients on the treetops concentrate on the trunk.

Stay+days and a half before pruning.

When picking, stick a sharp machete on the trunk and flatten it from bottom to top, and cut it into copper scars or bull's eyes. Don't cut too deep and hurt the cortex. It is best to smear the cut scar with lime water to prevent the invasion of miscellaneous bacteria and water accumulation, and it is also convenient to pile up and show off.
