Plant culture tank with functions of soil pollutant input control and dynamic monitor

Abstract

The invention relates to a plant culture tank with functions of soil pollutant input control and dynamic monitor. The plant culture tank comprises a root system culture tank body, a culture solution preparation module, a dynamic monitor module, a root system growth net cage and a water outlet, wherein the root system growth net cage is used for early culture of a plant root system; the culture solution preparation module comprises a driving stir rod, an outer wall scale, a flowrate regulating pump and the like, and can complete the process of preparing and delivering a culture solution containing pollutant substances; the root system culture tank body can complete reasonable flow distribution and flowrate recording process of the culture solution through a hollow-square shaped seeping pipeand the flowrate sensor; the dynamic monitor module is used for recording the distribution and concentration situation of pollutants in real time through a pollutant detection probe; and related dataobtained in experiments can be displayed by utilizing an instrument panel on the root system culture tank body, and data transmission is realized through a terminal interface. The plant culture tankcan integrate the preparation process, input process, water distribution process and detection process of the polluting substance-containing culture solution into a whole, is simple in operation and easy to debug, and can acquire relatively accurate data analysis results.

Description

technical field [0001] The invention relates to a plant cultivation box for soil pollutant input control and dynamic monitoring, belonging to the technical field of plant root exudates and soil pollutant degradation. Background technique [0002] A large number of studies on the remediation of contaminated soil by plant roots have found that the roots and their secretions can promote the transfer and degradation of soil pollutants through the direct degradation of enzymes, the co-metabolism and detoxification of root exudates. At present, the study of the migration and transformation process of new pollutants in soil and the absorption and degradation of roots has become a hot spot. A set of devices that can be used to study the degradation of pollutants in rhizosphere soil is also a necessary experimental equipment for researchers. Its functions include: Reasonably arrange the input of soil pollutants, control the concentration of soil pollutants, monitor and record dynamic...
