Problems solved by technology

The advantage of using a PVC connecting ring is that it can be fixed on the surface of the trunk for a long time, and can be used for repeated or continuous measurement and long-term measurement. The disadvantage is that large-scale measurement will consume a large amount of connecting materials, and the cost is high. Time will make the bark at the bonding part unable to breathe, resulting in necrosis and serious damage to the tree body

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific examples, but not as a limitation of the present invention.

[0012] exist figure 1 In the shown structure, the present invention includes a hollow cylinder 1, and the cylinder 1 is composed of two semicircular components 2, and one side of the components is connected by a movable shaft 4, so that the components can be opened and closed. It forms a hollow cylinder, and the other side of the component (opening and closing side) is equipped with a buckle mechanism, which can fasten the two components when closed, so as to avoid the loosening of the two semicircular components during the measurement process and affect the measurement; The side of the cylinder 1 is provided with a measuring port 5 communicating with the inside of the cylinder, which is used to connect with the measuring instrument, and the inner surface of the cylinder is provided with an airtigh...

Abstract

The invention belongs to the field of measurement of plant respiration, and relates to a packaging type connector. The packaging type connector comprises a cylinder body which adopts a hollow structure and is formed by two semicircle members, one side of each member is connected with one side of the other member through a movable shaft, a measurement port communicated with the interior of the cylinder body is arranged on the side surface of the cylinder body, and an airtight sponge layer is arranged on the inner side surface of the cylinder body. The packaging type connector is simple in structure and low in cost, the opening and closing type cylinder body structure is adopted, the connector does not have to be fixed on a trunk for a long period of time, the connection between the trunk and a measurement instrument is facilitated, the consumption of a connection material is avoided, a tree body is prevented from being hurt, and the packaging type connector can be used repeatedly; and guarantee is provided for the measurement of the respiratory rate of the trunk.

Description

technical field [0001] The invention belongs to the field of plant respiration measurement, and relates to a connector, in particular to a wrapped connector. Background technique [0002] Tree trunk respiration is one of the key processes to explain changes in forest ecosystem productivity. Measuring tree trunk respiration rate and understanding its bioenvironmental regulation mechanism will help to build a forest carbon cycle model and provide an estimation accuracy of forest carbon budget. In recent decades, due to atmospheric CO 2 As the concentration of greenhouse gases continues to rise, tree trunk respiration has become a research hotspot. There are many methods for measuring tree trunk respiration. In the early days, gas exchange method and airtight method were generally used. In recent years, the portable photosynthetic measurement system (Li-Cor6400) is mainly used to measure the trunk respiration rate. [0003] In the process of measuring tree trunk respiration, ...
