Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below.

[0024] The present invention needs to carry out through following several steps:

[0025] Acquisition of standard wood; acquisition of digital slice images; extraction of growth history data.

[0026] The first step, standard wood acquisition:

[0027] First, select a standard tree in the forest stand, measure information such as crown width, distance from adjacent trees, orientation, etc., mark the direction on the trunk, and cut it down along the root; then, measure the height of the trunk, the height of the first dead branch , The first is the high data of live branches, and the third is to saw off the branches without hurting the trunk, cut the trunk into four-meter sections, clearly mark the connection points and directions, and transport them to the laboratory for later use. Note that the wood slices should be processed as soon as possible after the standard wood is obtained, otherwise the...

Abstract

The invention relates to a tree growth history observation method which is suitable for forestry scientific research workers and can provide forestry scientific research workers with accurate data ofthe complete growth process of trees and forest stands. The method comprises the three steps of standard wood selection, digital slice image acquisition and growth history data extraction. The methodhas the advantages that an improved woodworking machine tool is added with a longitudinal slide rail and can well control the cutting thickness and precision of wood; full-tree tree growth history data of the millimeter level can be acquired; the growth process of trees can be grasped in more detail; each section is stored as an image; the information of various measurement factors of trees can beextracted through computer software; and image data can be repeatedly studied, but an original tree can only be studied once, and cannot be repeatedly studied.

Description

technical field [0001] The invention relates to a tree growth history observation method, which is suitable for forestry scientific research workers and can provide forestry scientific research workers with accurate data on the complete growth process of trees and stands. Background technique [0002] Forestry researchers usually construct tree growth models by studying factors such as tree height, diameter at breast height (ground diameter), crown width, and branch length of trees in different growth periods, so as to better study the growth laws of trees and guide forest management. , to achieve the purpose of forest management. [0003] The determination of tree growth process is an important method and means for forestry researchers to study the growth process of individual trees and forest trees in their stands. By studying the growth process of trees, scientific researchers can understand the growth process of trees and the forest stand, and provide theoretical data s...
