Root system is the main research object of rhizosphere ecology and a key element of underground ecology.Root system research mainly adopts MiniRhizotron technology, especiallyIt is VSI-BARTZ root systemAnalysis System, formerly known as Bar in the United StatesThe BTC micro root window root observation system produced by tz company has become a classic instrument for studying root systems using micro root window technology（“Themost commonly used MR(Minrhizotron) systems are produced by Bartz Technology Corporation”—— Quoted from Eshel, A.&Beeckman, T. Plant Roots: The Hidden Half. 4^thedition. CRC Press, New York,USA. 2013）. When studying plant roots solely using micro root window technology, transparent root canals are generally inserted longitudinally (usually at a 45 degree angle) into the soil profile. This longitudinal insertion method can easily cause roots to grow along the root canal, resulting in errors. By combining with permeameter technology, the root canal can be installed horizontally - equivalent to setting up a root observation strip at different depths in the soil profile. This not only avoids the deviation caused by vertical installation, but also enables three-dimensional dynamic observation and analysis of the root system. Combined with monitoring techniques such as soil moisture and temperature in the soil profile using the permeameter, it can comprehensively analyze the spatiotemporal dynamics of the root system and its influencing factors, stress response, etc., becoming an important means of research in underground ecology, rhizosphere ecology, and other fields.
