Branches pruned from short and extremely short shoots are commonly called "dragon claws", because each fruiting mother vine is short and looks like a dragon claw, and the main vine straight to the top is called a dragon trunk. The types of trunk pruning are mainly distinguished from the number, size and trunk of main vines.
The difference between single dragon trunk, double dragon trunk and multi-dragon trunk lies in the different number of trunks. In production, a plant with only one trunk extending straight to the top of the frame is called single dragon trunk, two trunks are called double dragon trunk, and three or more trunks are called multi-dragon trunk. In terms of frame matching, single dragon stem is suitable for small scaffolding, and double dragon stem and multi-dragon stem are suitable for large scaffolding. Ssangyong stems are widely used in production, because there are too few Otawa.
Common dragon trunk shapes
The difference among big dragon trunk, small dragon trunk and short arm trunk lies in the different lengths of trunks. In production, the trunk of the main vine is called Dalong trunk, the trunk of 4-6 meters is called Xiaolong trunk, and the trunk of less than 4 meters is called short arm trunk. In terms of frame collocation, the big dragon trunk is suitable for large scaffolding, the small dragon trunk is suitable for small scaffolding, and the short arm trunk is suitable for hedge scaffolding. Small dragon stem pruning and short arm dragon stem pruning are widely used in production, because the pruning time of large dragon stem pruning is long and a large number of fruits are late. Among them, the short-arm dragon trunk can be divided into single-arm dragon trunk and double-arm crossed dragon trunk according to the number of main vines. Both of them are suitable for cold-proof areas buried underground in winter, but the difference is that the latter is beneficial to control the tree potential and adjust the balance of growth and fruit because of its flexible distribution of arms and large expansion space.
Trunk of brachiosaurus
The difference between the trunk-free form and the trunk-free form lies in whether there is a trunk or not. In production, the trunk-free form is called a tree form in which the main tendrils grow directly from near the ground without obvious trunk, and the trunk-free form is called a tree form in which the main tendrils grow from near the frame surface and the lower part has a certain trunk.
The former is suitable for areas with buried soil in winter, while the latter is suitable for areas without buried soil in winter. The trunk adopts the shape of inclined plastic trunk, which can also be used in buried cold areas.
