I. Product Introduction

The GXY-A Plant Root Analysis System is a scientific instrument used for analyzing plant root structure and growth status. It captures and analyzes plant root images through scanning, enabling measurement of parameters such as total root count, number of root tips, total root length, average root diameter, total root volume, branching points, and more. It also supports color analysis, offering powerful functionality to meet various research needs.

II. Application Areas

The Plant Root Analysis System is widely used in agriculture, forestry, environmental protection, and other fields. By detecting and analyzing plant roots, it provides insights into crop growth conditions, nutrient absorption capacity, and stress resistance. This helps farmers develop more scientific and rational planting and fertilization plans, thereby improving crop yield and quality.

III. Features

Root Analysis Functions:

1. Topology Analysis: The system automatically performs root topology analysis, determining parameters such as root connectivity, length, and volume. It automatically distinguishes lateral root levels and analyzes parameters of the main root or any lateral root. The root hierarchy is divided into 8 levels for more accurate analysis.

2. Nodule Analysis: Automatically identifies and analyzes the proportion of nodule volume in the root system, objectively determining nodule count, nodule surface area, nodule surface area contribution, nodule volume, and nodule volume contribution. Users can manually add unrecognized nodules or delete incorrectly identified ones for improved data accuracy.

3. Connectivity Analysis: Accurately analyzes angular relationships between root segments within the root system.

4. Segmented Measurement: Segments and categorizes roots based on diameter, projected area, surface area, volume, and length. Supports custom categorization settings, automatically measures length, projected area, surface area, volume, and distribution parameters for each diameter segment, and outputs data histograms for visualization.

5. Smart Calibration for Precision: Allows merging of branches, deleting connections, merging root tips, disconnecting segments, burr removal, main root correction, lateral root correction, and root thickness adjustment for enhanced operability.

6. Automatic Noise Removal: Eliminates noise by setting pixel values to highlight target root contours.

7. Automatic Calibration: Converts pixel measurements to actual lengths after user input of scanning resolution.

8. Personalized Display for Easier Observation: Supports parameter selection for image analysis, displaying root endpoints, nodes, connecting segments, nodules, main roots, levels 1–6 lateral roots, and lower-level lateral roots in different colors for intuitive differentiation.

9. Image Binarization: Adjusts grayscale contrast to better segment roots and modify the background, improving analysis accuracy.

10. Restore to Original Image: Reverts analyzed or modified images back to their original state upon opening.

11. Target Area Analysis: Manually select specific regions for analysis, increasing flexibility and data accuracy.

One-Click Multi-Parameter Analysis: With a single click, accurately obtain parameters including total root count, number of root tips, total root length, average root diameter, total projected area, total root volume, R/G/B, RHS, total connection points, endpoints, nodes, branching points, overlap count, and fractal dimension.

Software Encryption for Data Security: Uses dynamic QR codes + hardware dongle encryption, registering user institution information to prevent loss or misuse.

High-Throughput Automated Analysis: Batch processes over 100 images at once, automatically saving results to save time and effort.

Automatic Data Saving: Pause or resume analysis at any time, with automatic progress saving.

Data Export in Tabular Format: Export images or data to folders, with data appendable in Excel format.

Integrated Mobile App and Cloud Platform: The "Fingertip Cultivation" app and cloud platform enable multi-platform data sharing, real-time viewing and export, and secure long-term data backup.
