The present disclosure provides a field integrated device for automatically shielding and collecting rainwater and simulating rainfall and an experimental method. The field integrated device comprises a roller shutter assembly. A rainfall assembly and a rainwater collecting assembly are fixed on the roller shutter assembly. The roller shutter assembly guides rainwater into the rainwater collecting assembly while shielding the rainwater. The rainfall assembly is connected with a pumping assembly. The pumping assembly transports the rainwater to the rainfall assembly to realize artificial rainfall simulation. The pumping assembly is fixed in a solar module. The solar module is electrically connected with the pumping assembly and a driving assembly in the roller shutter assembly. The solar module is in signal connection with a remote signal end.

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.
