Field in-situ continuous low-abundance 13CO2 isotope labeling device and method

Abstract

The invention discloses a field in-situ continuous low-abundance 13CO2 isotope labeling device and method, relates to a simulator for detecting crop rhizosphere respiration and labeling plants, and solves the problems of low labeling precision and high cost of a pulse labeling mode of a traditional C element labeling device or method for the plants. A labeling box is a transparent box with a through hole in the side wall, a combustion end of a combustor penetrates the through hole of the labeling box and extends into the labeling box, the tail end of the combustor is simultaneously communicated with a gas outlet of a liquefied gas bottle and a gas outlet of an oxygen bottle, an electronic fire maker is arranged at the combustion end of the combustor, a fan is fixed to the middle of the inner top of the labeling box, an air conditioner is fixed to the upper portion of the side wall of the labeling box, a CO2 measurement and control device and a humidifier are positioned in the labeling box, a dehumidifier is fixed to the lower portion of the side wall of the labeling box, and the fan, the air conditioner, the CO2 measurement and control device, the electronic fire maker, the dehumidifier and the humidifier are controlled by an automatic control system. The device and the method are used for performing continuous low-abundance 13CO2 labeling for crops.

Description

Technical field [0001] The invention relates to a simulation device for detecting crop rhizosphere respiration and marking plants. Background technique [0002] In the past, people usually used high abundance 13 CO 2 For pulsed labeling, few people use high abundance 13 CO 2 Continuous marking, discontinuous marking of crops, high marking cost, backward detection methods, large errors and low precision. Now, with the advancement of science and technology and the increase of greenhouse gases in the atmosphere, people have continuously improved the research methods and methods for the distribution of crop photosynthetic products, and people are soberly aware that the use of continuous 13 CO 2 The importance of labeling, it determines the CO in the fixed atmosphere of crops 2 The ability to affect the ecosystem through redistribution. Therefore, researchers at home and abroad in greenhouse gas and plant physiology 13 CO 2 Marking research is very important. 13 C continuous labeling ...
