Shape of Myrica rubra: The tree shapes of Myrica rubra when cultivated in the open field include natural joy shape, natural round head shape, trunk shape, evacuation layered shape and so on.

However, the trunks and crowns of these trees are high, which is not conducive to the operation and management of early-maturing cultivation in greenhouse.

Therefore, when all localities want to cultivate the original big trees in the greenhouse to be precocious, they must first transform the crown to make it a low crown. For gardens cultivated with seedlings, it is necessary to cultivate a natural joy with low stems and short crowns.
