T/HXCY 163-2026 Technical specifications for UAV remote sensing monitoring of alfalfa germplasm resources phenotypes at ultra-Low altitudes
Basic Information
Scope
This document is applicable to the phenotypic high-throughput monitoring and fresh weight estimation of alfalfa germplasm resources plots (including breeding test fields and resource conservation plots). The core application scenarios include obtaining growth phenotypic parameters such as alfalfa plant height, canopy structure, regeneration rate, and growth dynamics, as well as rapid estimation of fresh weight at the early flowering stage. It is suitable for ultra-low altitude operations conducted by small/lightweight rotary-wing drones, and serves as a general technical protocol. This document specifies the terminology and definitions, equipment requirements, operational guidelines, data processing, and methods for constructing and validating phenotypic parameter inversion models for alfalfa germplasm growth phenotypic monitoring based on ultra-low altitude drone remote sensing.
