Problems solved by technology

The leaf part of the plant usually adopts the method of direct sampling, but the trunk part of the plant should not adopt the method of direct sampling similar to the leaf. Direct bark sampling is easy to lose a lot of surface deposited particles, which is difficult to quantitatively measure.

Abstract

The invention relates to the technical field of measuring of particulate matter adsorption quantity of plants, in particular to a plant trunk surface particulate matter sampling device and a particulate matter adsorption quantity measuring method. The plant trunk surface particulate matter sampling device comprises a guide pipe, a sampling bottle, a scrubbing brush, a washing bottle with ultrapure water, adhesive tape arranged on a tree trunk and sealing cement gum. The sealing cement gum and the first adhesive tape enclose a sampling surface with the periphery being sealed, and a suspension liquid collection region is formed above the sealing cerement gum. A plastic thin film is laid on the upper surface of the sealing cement gum, and the guide pipe penetrates through the sealing cement gum and the plastic thin film to be communicated with the sampling bottle and the collection region. The scrubbing brush and the washing bottle are used for scrubbing the sampling surface. By means of the plant trunk surface particulate matter sampling device and the particulate matter adsorption quantity measuring method, the particulate matter adsorption quantity on the surface of the tree trunk in unit area can be effectively measured, the loss generated in the particulate matter sampling process is reduced to the maximum degree, and the measuring accuracy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of measuring the amount of adsorption of particles by plants, in particular to a device for sampling particles on the surface of plant trunks and a method for measuring the amount of adsorption of particles. Background technique [0002] At present, in order to improve the air quality, increasing the green area is an important measure. Plants can absorb particulate matter suspended in the air, which has also triggered research on the adsorption capacity of plants for particulate matter. However, at present, the research is mainly on the adsorption capacity of plant leaves, and no research has been found on the adsorption capacity of plant branches for particulate matter. The current domestic research on plant branches mainly focuses on the absorption of heavy metals and pollutants by the bark tissue, and no research has been conducted on the suspended particles blocked by the surface. In fact, more attentio...
