- Hyperspectral monitoring of SPAD values in fresh tea leaves based on spectral preprocessing and feature selection
- “The optimal technical route of "spectral preprocessing feature screening modeling" has been established, and researchers have developed a rapid and non-destructive monitoring system for SPAD values of fresh tea leaves, providing methodological support for precise nitrogen fertilizer management in tea gardens.”
