AI Technical Summary

Technical Problem

Traditional methods for collecting root exudates from flue-cured tobacco are highly destructive, complex to operate, and difficult to achieve continuous dynamic monitoring in the field. Existing devices are also ill-suited to the complex conditions in the field.

Method used

A non-destructive in-situ exudate collection device for flue-cured tobacco roots, comprising a first connecting shell and a second connecting shell, was designed. It employs an anti-pollution filter, a composite adsorption layer, and a temperature sensor, and uses elastic clips to fix the root system, thereby achieving non-destructive collection and continuous monitoring.

Benefits of technology

It enables non-destructive, continuous, and dynamic monitoring of tobacco root exudates, ensuring sample purity, adapting to changes in root growth, accommodating the collection of organic and inorganic substances, and simulating different soil temperature environments.
