investigate tress growth situation Wood core extractor: d=5mm Drill pipe length: 20cm, 25cm, 30cm, 35cm, 40cm
Application
It is applied to investigate tress growth. Through drilling tree core samples, without destruction of trees normal growth, it can identify trees growth rate, age of the trees, trees growth hardness degree and nutrients migration.
Characteristic
Adopt international advanced technology standards, use high quality alloy steel, still intact after more than 200 experiments.
Usage
In the 1.3 meters of the tree, horizontally spin the growth awl to the trunk center, when reach the center, make a reverse rotation, and get wood core within core extractor. Tree growth condition can be analysed by watching wood core color distribution.
Composition
Sleeve, awl and a core extractor
Model
Wood core extractor: d=5mm
Drill pipe length: 20cm, 25cm, 30cm, 35cm, 40cm
Plant Growth Awl
