Embodiment 1

[0029] Degradation experiment of polyethylene (PE) in rhizosphere soil

[0030] Firstly, the plants selected according to the research experiment are pre-cultured in the root growth cage, and this process does not require contact with pollutants (polyethylene). After the pre-cultivation is completed, the non-polluted soil is filled into the root culture box, and the dynamic monitoring module is assembled and placed into the root growth net cage with plant samples. Prepare the culture solution containing polyethylene in the culture solution preparation module, use the scale on the outer wall and drive the stirring rod to prepare the culture solution to the concentration required for the experiment (polyethylene concentration 0.5 mg·L-1), control the flow adjustment pump to transfer the culture solution It is input into the root cultivation box through the transmission pipe, and finally the flow is reasonably distributed through the return seepage pipe and combined with the flow...

Abstract

The invention relates to a plant incubator for soil pollutant input control and dynamic monitoring, comprising a root system culture box body, a culture solution preparation module, a dynamic monitoring module, a root system growth cage and a water outlet. The root growth cage is used for the pre-cultivation of plant roots. The culture solution preparation module includes components such as driving stirring rod, outer wall scale, and flow regulating pump to complete the preparation and delivery process of the culture solution containing pollutants. The seepage tube and flow sensor complete the process of reasonable distribution and flow recording of the culture solution. The dynamic monitoring module records the distribution and concentration of pollutants in real time through the pollutant detection probe. The relevant data obtained from the experiment can be used by the instrument on the root culture box. Disk for display and data transmission through the terminal interface. The device integrates the preparation process, the input process, the water distribution process and the detection process of the culture solution containing pollutants into one, the operation is simple, the debugging is easy, and relatively accurate data analysis results can be obtained.

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...
