How to determine the specifications of big trees with clumps?

The national standard DBH is the diameter at 1.2m, and the ground diameter refers to the diameter at 0. 1 on the ground.

In Sichuan, the weighing cage you mentioned generally only refers to its crown width and crown height, and you can also talk about the ground diameter.

You can still do this if you want to sell it. If you want to buy it, it's not worthwhile. Give a simple example: 3cm Lagerstroemia indica only needs 10 yuan, 1000cm Lagerstroemia indica needs 1000 yuan or more. If you put several plants together, they will grow together in a few years. There are also breeders who connect several pieces together when raising seedlings, and grow into bulls. Like this cage, the ground diameter is calculated, and the old-school Party A will calculate the crown width.
