Zhou Xiaoming, chief photographer of ZhenzhouFu and Yizheng Grand Wharf, excerpted the information released by the WeChat public account platform of Yangzhou Release on November 6, 2021: On the embankment of a production river in Yizheng Xinji Town, there are many local plants such as trees, privets, simple trees, small fruit roses, wild chrysanthemums and so on. Among the many plants, there are two small trees about 1 meter apart, they are nestled next to each other, and finally "rely on each other" is naturally connected, forming a "lianli branch" small tree is naturally connected into a "lianli branch".
"In heaven wish to be likened to a winged bird, in the earth wish to be a branch." Since ancient times, the winged bird and the branch have become symbols of beautiful love.
In order to photograph the blooming wild chrysanthemums, the reporter entered the embankment of a production river in Xinji Town and inadvertently found two small trees connected together.
Both of these small trees are simple trees. In late autumn, the leaves turn yellow, with one small tree about 5 centimeters in diameter and the other about 3 centimeters in diameter.
The thicker small tree has a branch at a height of about 1.5 meters above the ground; the thinner one grows obliquely, and the body of the tree is just on the branch of the thicker tree, forming a large pattern of supporting the small.
After several years of growth, the contact parts of the two trees have grown into one. The reporter lifted the small trees so hard that they could not separate them in any way.
Look closely, the contact part of the two trees is already you have me, I have you.
The contact point rubs on the injury and melts together as it heals
Chen Weiyuan, a professor at the College of Landscape Architecture and Horticulture of Yangzhou Vocational University, introduced that the reason why these two small pu trees can become lianli branches is first of all that they belong to the same tree species, "the principle of lianli branches is actually similar to grafting, and the survival rate of the same kind of tree grafting is the highest." ”
Secondly, the two small trees should have a relatively close contact point, only close contact, as the tree grows and the external force (such as wind), they can rub against each other, resulting in injury to the contact part, "Usually, woody plants have a strong self-healing and regenerative ability, after the friction of the contact part is injured, when the wind and waves are calm, both begin to heal themselves, in this process, the internal transport tissue (formation layer) is integrated, thus forming a connecting branch of you have me, I have you." ”
"It's a coincidence." Chen Weiyuan said that this resource can be specifically protected.
The reporter noticed that the smaller tree, the body of the tree has traces of being deeply entangled by the cane, perhaps it is the role of this cane, so that the tree grows obliquely, and finally just happens to be on the branch of the thicker tree.
There are also branches in these places in Yangzhou
Yangzhou's lianli branches, the most famous is the slender West Lake leaf forest of the triangular maple lianli branches, a tree has multiple lianli. Slightly different, the contiguous branches of the Slender West Lake Delta Maple are friction and injuries between the branches of the same tree, and eventually become one.
In nature, naturally formed branches are rare. In the Shaobo Locks, there is a cedar tree with a series of branches; and in a forest farm in Jiangdu, there is a privet tree with a series of branches.
However, in urban landscaping, artificially cultivated branches are more common. For example, in recent years, the weaving of osmanthus flowers and the weaving of ziwei that have appeared on the streets of Yangzhou are through artificial weaving to make the trees form a connection.
Moreover, in principle, grafting is the universal application of connecting branches. Grafting is a common method of garden gardening and the development of forest fruits, and people often eat peaches, pears, grapes, apples, etc., which can be replaced by grafting to increase yield.
