用途：PlantPen植物NDVI測(cè)量?jī)x是一款設(shè)計(jì)精巧、可快速測(cè)量植物NDVI指數(shù)的便攜式儀器可根據(jù)反射系數(shù)確定植物特征，通過(guò)各種反射系數(shù)可以評(píng)定葉綠素含量。

        NDVI(歸一化植被指數(shù))是通過(guò)計(jì)算植物葉片對(duì)660 nm和740 nm兩種波長(zhǎng)光發(fā)射情況計(jì)算得到的值，反應(yīng)植物葉綠素含量的重要參數(shù)。一個(gè)方便的葉夾、簡(jiǎn)單的兩鍵操作以及明亮的顯示屏使得PlantPen在不干擾調(diào)查植物（無(wú)葉片脫落或損壞）下仍方便使用。

        測(cè)量數(shù)據(jù)存儲(chǔ)于儀器內(nèi)部，可選擇藍(lán)牙（NDVI 300-B）或USB數(shù)據(jù)線（NDVI 300-U）與計(jì)算機(jī)連接，使用專業(yè)FluorPen軟件進(jìn)行數(shù)據(jù)傳輸和可視化分析；可選配GPS模塊。

特點(diǎn)：

    設(shè)計(jì)緊湊、堅(jiān)固的PRI非常適用于野外環(huán)境、植物溫室等

    *的手持葉夾，雙鍵操作，LED顯示屏設(shè)計(jì)，使用方便

    非侵入式無(wú)損測(cè)量

    4節(jié)AAA電池供電，方便耐用

    USB或藍(lán)牙傳輸數(shù)據(jù)，專業(yè)軟件進(jìn)行可視化分析

案例分析：兩種石耳在失水狀態(tài)下的光譜反射率和光合效率研究

        對(duì)于NDVI, Umbilicaria arctica和Umbilicaria hyperborea隨著水勢(shì)的變化有相同的變化趨勢(shì)，均隨著水勢(shì)降低而降低，但兩物種之間存在差異。*水化的U. arctica的NDVI在0.55-0.75之間，U. hyperborea的NDVI比較低，在0.30-0.55之間；脫水后的U. arctica在0.55-0.30之間，而U. hyperborea在0.30-0.15之間。
