Plant underground ecological process observation system

Abstract

The invention provides a plant underground ecological process observation system. The system comprises a plurality of plant planting boxes, a transparent glass observation window, an underground observation channel, a temperature and humidity adjusting device used for adjusting the environment of the underground observation channel, a spraying device and a drainage system. The plant planting boxes are located on the two sides of the underground observation channel, and the top faces are located above the ground. The top of the box body is provided with an opening, the box body is arranged on the two sides of the underground observation channel, the multiple first partition plates divide the box body into a row of multiple independent quadrats, and multiple independent compartments are arranged in the independent quadrats; a transparent glass observation window is arranged on the side surface, close to the underground observation channel, of the independent quadrat, and a reading grid line and a plurality of sampling ports are arranged on the transparent glass observation window; and a reinforcing layer is built at the top of the underground observation channel.

Description

technical field [0001] The invention relates to the technical field of plant root observation, in particular to a plant ecological process observation system. Background technique [0002] The research on the subterranean process of the ecosystem, especially the research on the root system, often adopts destructive sampling methods such as root digging. If a time-series measurement is performed, a very large number of experimental units or repetitions are required. In recent years, the micro-root window technology has provided a good way for the growth of plant roots, but the observation range of the micro-root window is very limited. It can only observe the root morphology locally and only display the changes of the root system in a small range where the micro-root window is located; At the same time, because the roots of different plants and different ages are difficult to distinguish, there is no effective identification method for dead roots and live roots, and the turn...
