9. plant growth dynamic monitor according to claim 1, it is characterised in that：The transparent incubator with it is described
The opposite face of photographing device is equipped with scale.
10. the dynamic computational methods of a plant growth, it is characterised in that：Including step S1, distinguished using multiple photographing devices
Timing takes pictures to the root system of plant in transparent incubator from different perspectives, the photo for the different angle that the same time is shot
It is transmitted in the Image-Pro Plus softwares in computer, the dimension of picture of shooting is corrected by ruler；
S2 demarcates in picture the color gamut for representing root system by rgb color space；
S3 selectes calculating parameter, obtains target root system sectional area and spatial position coordinate；
S4 obtains the sectional area and spatial position coordinate of different time target root system, you can determine plant roots using the above method
The speed of growth and direction change of system.
