1、 Purpose:
Used for plant root analysis, annual ring analysis, etc.

2、 Main technical indicators
Equipped with an optical resolution of 4800 × 9600 and an A4 extended dual light source color scanner, the reflective scanning format is an A4 extended format of 35.6 cm × 21.6 cm, the transparent scanning format is 30 cm × 20 cm, and the minimum pixel size is 0.0053mm × 0.0026mm.
2. Plant root system analysis:
(1) Root total length, average root diameter, total root area, total root volume, root tip count, fork count, overlap count, root diameter grade distribution parameters, and root tip segment length distribution.
(2) Customizable segmented diameters at unequal intervals, automatically measuring the length, projected area, surface area, volume, and distribution parameters of each diameter segment; Capable of conducting color analysis of root systems, determining the number of surviving roots, and outputting the diameter, length, projected area, surface area, and volume of roots of different colors.
(3) It can perform topological analysis of the root system, automatically determine the number of connections, relationship angles, etc. of the roots, and independently analyze the length and branching number of the main root or any lateral root. It can display the corresponding parameters of any diameter segment of the marked root system separately (the number of grades and diameter range can be changed arbitrarily, and can be customized at different intervals), and can perform root branching, cutting, merging, connection and other corrections. The correction operation can be rolled back to quickly obtain 100% correct results.
(4) The box dimension method can be used to automatically measure the fractal dimension of root systems. The proportion of rhizobium volume in the root system can be analyzed to objectively determine the contribution of rhizobium cells.
(5) Can automatically measure the parameters of the stem, body, and beak of rapeseed pods. Can automatically measure the length of various grains.
(6) Large scale fully automated root analysis, with editing and correction of various analysis result graphs.
(7) Can measure the leaf area, length, and thickness of various types of needles.
(8) Capable of large-scale automated estimation of root biomass distribution.
3. Tree ring analysis:
(1) It can automatically read the number of annual rings, average width of each ring, width of early and late wood, tangential angle and area of each ring.
(2) It can automatically divide the boundaries of tree rings, early wood boundaries, late wood boundaries, and identify very narrow tree rings. It can interactively delete fake rings, insert broken rings, and automatically generate an analysis chronology.
(3) With the option of 'Fine' analysis, it can automatically analyze annual rings with a width of ≤ 0.2mm, and the measurement data obtained from the analysis has the ability to further perform cross dating and data analysis processing.
(4) Calculate the total area of the tree disk and analyze the sapwood area of the wood.
4. Each analysis image, distribution map, and result data can be saved, and the analysis results can be output to an Excel spreadsheet, which can also be used to output analysis markers.
