Abstract

The invention discloses a CO2 flux automatic monitoring system of a farmland ecosystem. The CO2 flux automatic monitoring system comprises a plurality of static visible boxes, automatic lifting machines and CO2 monitoring devices which are sleeved, wherein the CO2 monitoring devices are arranged in the static visible boxes and are used for detecting the CO2 concentration in the static visible boxes in real time; the automatic lifting machines are used for clamping the static visible boxes to adjust the heights of the boxes; the multiple static visible boxes and the automatic lifting machines which are sleeved are used for enabling the CO2 monitoring devices to detect the CO2 concentration at different heights. The CO2 flux automatic monitoring system has the characteristics of convenience for operation, continuity of monitoring and easiness in carrying and assembling, and can be used for monitoring the research on discharging of CO2 flux of the farmland ecosystem in different growing stages under different height conditions.

Description

technical field [0001] The invention belongs to the technical field of ecology, in particular to a farmland ecosystem CO 2 Flux automatic monitoring system. Background technique [0002] CO in farmland ecosystem 2 Diurnal variation of flux, CO of crops in different growth stages 2 Flux variation law, and crop CO 2 There is an urgent need to carry out relevant research work on the flux change law and carbon balance, which is also a research hotspot in related disciplines (agronomy, ecology and environmental science, etc.). [0003] In the current research work, the control of the height of the static light box is mainly realized by artificially superimposing the plexiglass static light box. Its limitations are: it is difficult to operate when stacking, it is difficult to carry out continuous monitoring and multi-site simultaneous monitoring, and it is easy to cause safety hazards during the operation process, and the static box is inconvenient during transportation. Con...
