• ROOT-700 Root Growth Monitoring System    (GO TO TOP)

Application:

plant roots play an important role in fixing plants and obtaining moisture and nutriens,however,the limit of soil non-observability brings some diffculties to the study of root ecology.Therefore find out ways to observe root growth in situ is particularly important for studying root ecology.Root growth monitoring system using the currently most popular micro-root window technology in the world to solve this problem.Root profile images can be obtained by rotating 360°multi-level rotations in situ in the soil, the growth dynamics of living roots in soil can be scanned and monitored.Widely used in nursery stock cultivation,crop growth model research,root pathology and other fields. 

Measuring Principle: 

When measuring the scanner head should inserted into a clear rooted probe tube preembedded in the soil,the computer will control the scanning head to automatically scan the roots of the root canal scanning section of the wall image.Users can easily scan root images of different depths,as well as images of different roots,as well as images of different roots(different root cannal).High-resolution images are obtained with each scan and the user can see the detailed structure of the rootsystem(or even the soil particles)
