Selection of cone length for tree growth

Different lengths and sampling diameters of tree growth cones can be selected for different types of wood and trees. If the diameter of the tree is1In terms of rice, choose50cmA growth cone of length is sufficient. The most commonly used ones are30cmIf the tree material is hard, it is recommended to choose the left and right growth cones2Wire thread, selection of sampling core diameter5.15mmJust enough. If the tree is thick, you need to choose a length of80cmThe above growth cones suggest selecting the diameter of the sampling core12mmThe growth cone of trees.

Characteristics of tree growth cones/Ms. Wang

The Swedish tree growth cone is made of high-quality Swedish special steel, which ensures its durability and quick sampling.

The drill bit comes in two thread and three thread options, suitable for different types of wood The boring drill bit has a PTFE coating to reduce the resistance when the drill bit enters and exits, and the handle is equipped with a PTFE anti slip sleeve.

Purpose of tree growth cones

The tree growth cone is a fast and reliable tool for calculating the age of trees. At present, the Swedish tree growth cone has relatively high recognition in China. The tree growth cone is mainly used to analyze and determine indicators such as tree growth rate, tree age, tree growth solidity, environmental pollution, and nutrient transport by drilling tree core samples without damaging the normal growth of trees. Applied in fields such as forestry and forest ecology. It can also be used to measure the degree of deep keratinization of trees, detect wooden buildings, and identify the age of ancient trees.

Tree growth cone parameters：

Different lengths:10-80cm

Different sampling diameters:4.35、5.15、12 mmGenerally used5.15 mm.

How to choose drill bit thread style:

The two-line threaded growth cone is suitable for hard trees, and can rotate in with each rotation8mmThe three thread type is suitable for trees with soft texture, and can be rotated in with each rotation12mmIf possible, try to choose a two-line threaded type, as this type of growth cone has a longer service life.

Instructions for using tree growth cones:

Open the rotatable side of the growth cone and remove the sampling drill bit. Unscrew the middle screw of the growth cone, insert the drill bit and tighten the screw to use.

About breast height in trees1.3At the rice level, rotate the assembled growth cone horizontally towards the center of the tree trunk. After reaching the center, rotate it in the opposite direction once, and then insert the core puller into the hole inside the cone to remove the wood core.
