1、 Micro root window technology

Root systems and mycorrhizae are crucial for plant performance and various ecosystem and biogeochemical processes. Therefore, observing the development of root systems is crucial for understanding the plant performance of natural and artificial ecosystems (crops, etc.) and revealing the dynamic processes of water, carbon, and nitrogen in terrestrial ecosystems. Non destructive root and rhizosphere imaging can be used to measure a series of processes, organisms, and events under controllable conditions or abiotic and biotic stresses, including root development, turnover, distribution (root architecture), as well as the emergence of mycorrhizal root tips, hyphal development, and even the development of rhizobia and soil animals.

VSI-BARTZMicroroot canal system is a non-destructive, fixed-point in situ qualitative and quantitative observation tool for directly observing and studying the growth, lifespan, and distribution of plants and hyphae. Its greatest advantage is that it can continuously monitor the changes in a single fine root from birth to death without interfering with the growth process of fine roots, and can also record the growth, production, and phenological characteristics of fine roots, root hairs, and mycorrhizae. It is used to estimate the underground ecosystemCAllocation andNAn effective method for balanced research, combined with the provided root analysis software, can quantify root related data, including root length, area, number of root tips, diameter distribution pattern, number of dead and surviving roots, and so on.

2、 Highly customized micro root window system—VSI-BARTZMicro root window system

VSI-BARTZThe micro root window system consists of a host controller, camera module, gear system, and power supply module unit. The micro root window camera can be used for commonly used5or7cmThe inner diameter of the micro root canal (other sizes of root canals can be customized) can meet the needs of existing root canals and make it easy to upgrade the original camera system. Image processing can be fully automated, including the recognition of micro root canals, image acquisition at preset positions, and re acquisition of images at already acquired positions. The system is highly customized to meet different research and funding needs.

VSI-BARTZThe micro root window system can obtain full HD images of the selected area and adjust the size of the observation area according to research needs and image analysis requirements. The built-in software automatically corrects slight distortions in the original image caused by the curved surface of the micro root canal. The image acquisition system can be accessed through a handheld tablet or laptop（Bartz ICAPProgram operation. Wireless or wired transmission can be selected. Lithium battery or power cord（110V-230V）Power supply, imaging area (standard:20×20mm）Can make adjustments.

3. Automatic Micro Root Window Camera SystemVSI AS-18(Used for vertical micro root canal observation)

3、 Automatic Micro Root Window Camera SystemVSI AS-17

Automatic Micro Root Window Camera SystemVSI AS-17It is designed for observing micro root canals installed horizontally or at a flat angle, and is commonly used in rhizosphere laboratories or other experimental facilities equipped with a large number of micro root canals. The imaging unit composed of dual cameras with opposite directions provides dual viewing angles（dual view system）； The imaging unit can be installed on the rack extending from the micro root canal and controlled and collected through a tablet computer based on the micro root canal number. After installation, the imaging unit can independently and accurately take photos at the designated position and then return to the initial position. This design allows operators to simply replace the imaging unit between different micro root canals through scanningRFIDBy setting the micro root canal number on the wireless radio frequency identification (RFID) tag, multiple imaging units can be effectively operated simultaneously. The resolution of the collected images reaches ultra-high definition（2500dpi）And withICAPNaming system. The image is stored in two units within the imaging unitUOne of the disks, so it can be transferred to devices such as laptops at any time. The power supply of the imaging unit is rechargeable, easy to disassemble, and has a long lifespan. The software can pre-set the shooting position in batches or independently according to different types of micro root canals. The circular rack can be manually repositioned using the magnetic sealing cover at the end of the micro root canal to capture a complete image of the micro root canal. The rack can be left in the micro root canal——This is also the most convenient and can be used alternately between various micro root canals to save installation costs.
