Abstract

A field condition-based experimental apparatus for an ecological indicator of vegetation includes a plurality of isolation units arranged at intervals and an auxiliary mechanism detachably connected to the isolation unit. The isolation units include a plurality of isolation boxes arranged at intervals and respectively having a hollow structure, and a support frame respectively disposed at four corners of the isolation box. The auxiliary mechanism is detachably connected to the support frame. A soil layer is disposed in the isolation box. The experimental apparatus has a reliable structure and is easy to use. An appropriate number of isolation units are buried under field conditions based on experimental needs. Auxiliary mechanisms of different structures are mounted based on experimental conditions. This implements reliable detection of an ecological indicator of vegetation under the field conditions and effectively improves authenticity and reliability of detection results. The auxiliary mechanism facilitates disassembly and assembly.
