Problems solved by technology

However, this method needs to be dyed after felling, which is not only time-consuming and laborious, but also destroys the test sample tree, directly interrupting the follow-up experiment, and in many cases does not allow tree cutting

Embodiment Construction

[0021] The technical solutions of the present invention will be further described in detail below in conjunction with the embodiments.

[0022] 1. The traditional method of determining the width of sapwood by wood color:

[0023] Such as figure 1 As shown, the tree was sampled with a growth cone drill, and the color of the core was observed. The lighter part was the sapwood, and the darker part was the heartwood.

[0024] 2. The method of accurately measuring the thickness of the water-conducting sapwood of the trunk:

[0025] (1) Use a growth cone to drill a small hole 10 cm below the measured part of the trunk, and take out the inner wood core; the drill hole is blocked with a round rubber plug.

[0026] (2) Put the biological dyeing reagent into a sealed plastic bag, use a medical hose and a plastic needle to pierce the dyeing reagent through the rubber stopper and introduce it into the small hole to ensure that the dyeing agent fills the entire small hole without air. S...

Abstract

The invention discloses a method for measuring the thickness of trunk water diversion sapwood. The method for measuring the thickness of the trunk water diversion sapwood comprises the following steps: using a growth cone to drill a small hole at a position 10cm below the measuring position of trunk, removing the wooden core inside, and sealing the mouth with a rubber plug; putting a biological staining reagent in a sealed plastic bag, and using a medical hose and plastic needle to introduce the staining reagent into the small hole through the rubber stopper to ensure that the staining agent fills the entire small hole; and using the growth cone to drill the wood core at a position 10 cm above the small hole vertically after 2 to 3 hours of dyeing, so that the part stained with the staining reagent is the active water diversion sapwood, and the length of the part is measured to be the width of the water diversion sapwood. According to the invention, the tree core is drilled and stainedin the wild; the operation is simple and easy; the damage to the tree is small; the accuracy is high; and the accuracy of sapwood thickness measurement is greatly improved.

Description

technical field [0001] The invention relates to a method for measuring the thickness of the sapwood, in particular to a method for measuring the thickness of the water-conducting sapwood of the trunk. Background technique [0002] The trunk of a tree consists of bark and wood, which includes sapwood and heartwood. Sapwood is the secondary xylem formed in recent years. It is close to the bark and undertakes the role of water transport for trees, transporting the water absorbed by the roots to the leaves for evaporation. The heartwood is located inside the sapwood, which is gradually transformed from the inactive sapwood, and has no water-conducting function. Typically, the sapwood portion is lighter in color and the heartwood portion is darker in color. [0003] Sapwood plays an important role in the water physiological process of trees, responsible for the transportation and storage of water, minerals and nutrients. Therefore, in various studies such as studying tree tran...
