摘要

茶樹生長狀況監測，除能瞭解各栽植階段之生理狀況，更可推估植物對逆境的反應及耐受性。本研究結合作物生理量測及無人飛行載具（Unmanned Aerial Vehicle, UAV）多光譜影像，發展一快速非破壞性且大面積的茶樹生長評估方法。同時討論自然和慣行農法茶樹生理表現與生長狀態差異，並分析生理數值和光譜植生指標的相關性。初步發現，自然農法茶樹具備韌性，且紅邊波段和作物生理數值相關性較高。本研究之快速且大面積的茶樹生長評估方法，有助於茶園耕種管理，亦可成為目前極端氣候下早期預警之重要參考依據。

Monitoring tea tree growth status is essential for understanding physiological status at each planting stage and vegetation resilience to environmental stresses. The present study aims to develop a rapid, nondestructive, and large-area tea tree assessment method by combining crop physiological measurements and Unmanned Aerial Vehicle (UAV) multispectral images. Additionally, the differences in physiological performance and growth status of natural-based and conventional-based tea tree practices were discussed. Furthermore, the correlation between physiological measurements and spectral vegetation indexes was analyzed. The preliminary results have shown that the natural-based practice tea trees present high resilience, and the red edge spectral band has a higher correlation with crop physiological measurements. The proposed rapid, nondestructive, and large-area tea tree assessment method demonstrates a great opportunity for tea tree cultivation and management and future applications on early warning in the current extreme climate.
