Device and method for measuring respiration of tree branches and leaves

[0076] See Figure 1 to 8 . A device for determining forest wood branches and blade breathing, including a system 600, a breathing cartridge, and a pipe 601 that connects to the assay system and a breathing cartridge, including at least one branches or / and The via holes passing through the blade; in this embodiment, two through holes are provided on the breathing cartridge, and the two through holes are simultaneously used to secure the device on the branches, which is a fixed hole 101. The size of the fixing hole 101 is comparable to the diameter of the branches to be tested. In order not to affect the respiration and photosynthesis of branches and leaves, in this example, the breathing cartridge is an on / off transparent breathing cartridge, that is, a breathing cartridge that can be turned on and off can be made of transparent glass and resin material. The breathing cartridge is a normally open state to ensure that the air inside and outside the breathing box can be circulat

[0087] In this example, the method of determination of forest tree branches and blade respiration, including the following steps:

[0088] S1 select a specific branch and leaves as a target object for determination, and install the assay forest branches and blade breathing on the branch to be tested, such a target object is located within the breathing cartridge;

[0089] S2 Calculate the target object area: The leaf area in the breathing ring is obtained by the digital image processing method, such as using the image of the photo to calculate the leaf area by Photoshop; calculate the branch surface area within the respiratory ring by formula:

[0090]

[0091] S = πR 2 + πR 2 + πrl + πrl = π (r 2 + R 2 + RL + RL) (Formula II)

[0092] Among them, the R-upper end radius, R-lower end radius, H-branches long, L-bus.

[0093] S3 intersect the leaves area and branch surface area in the S2 as the total area of ​​the instrument input instrument parameters;

[0094] S4 based on the OFFSET
