Abstract

The invention discloses a field in-situ C3 crop photosynthetic carbon marking device and an application. The field in-situ C3 crop photosynthetic carbon marking device comprises a cuboid cover for placing a to-be-marked plant body, a detachable cylinder and a fan, wherein one side of the cuboid cover is directly grounded; the detachable cylinder is used for providing a place for generating and releasing carbon dioxide and is positioned in the middle of a cuboid cover top cover; and the fan is arranged in the cuboid cover, and a thermometer can also be arranged on an inner wall of the cuboid cover. According to the device for in-situ marking of C3 crop photosynthetic carbon in the field, materials are easy to obtain, mounting and dismounting are convenient, and a size and internal configuration of the cover body can be individually adjusted according to specific field experiments.

Description

technical field [0001] The invention relates to the technical field of isotope labeling, in particular to a device and application for in-situ labeling of C3 crop photosynthetic carbon in the field. Background technique [0002] Plant photosynthesis is the driving force of the carbon cycle between the land and the atmosphere. The non-structural carbohydrates synthesized by photosynthesis are transported to the underground through the plant phloem and released into the soil in the form of rhizosphere deposits. This part is transported to the soil Photosynthetic carbon is not only the main source of soil organic carbon, but also the source of nutrients and energy for soil microorganisms. At present, the mainstream method adopted by scholars at home and abroad to conduct research on photosynthetic carbon is to apply 13 C isotope labeling technology pulse-labels aboveground crops, and then uses mass spectrometry to measure the 13 C content, and then quantitatively analyze the ...
