A device for studying plant growth status

The invention provides a plant growth status research device, comprising a transparent container with an open top, inside the transparent container, soil to be studied is placed, including rhizosphere soil and non-rhizosphere soil; several sampling ports of different heights are set on the outer wall of the transparent container, inside the transparent container, there is a non-rhizosphere soil placement device where plants are grown, and the area between the non-rhizosphere soil placement device and the transparent container is used to place rhizosphere soil, quartz sand is placed at the bottom of the transparent container, and a permeable separation device isolates rhizosphere soil from the quartz sand, a water outlet is set at the bottom of the transparent container, which is connected to a monitoring device. This device enables observation of plant growth and root distribution, while simulating real soil environments, facilitating the study of plant growth and soil influencing factors. It holds significant importance for research in soil science and plant ecology.
