用途：PlantPen系列植物PRI & NDVI計(jì)是一款小巧的快速測(cè)量植物反射光譜指數(shù)的野外便攜式儀器，可根據(jù)反射系數(shù)確定植物特征。通過各種反射系數(shù)可以評(píng)定葉綠素含量，和其他重要的特征。有兩個(gè)標(biāo)準(zhǔn)版本光化學(xué)反射系數(shù)（Photochemical Reflectance Index，PRI）和歸一化植被指數(shù)（Normalized Difference Vegetation Index，NDVI）。整合了藍(lán)牙技術(shù)（藍(lán)牙模塊或USB軟件狗），F(xiàn)luorPen 1.1軟件提供可視化操作和數(shù)據(jù)傳輸?shù)絇C上。根據(jù)用戶需要，還可提供定制服務(wù)。

兩種標(biāo)準(zhǔn)版本：

■PRI 210植物光化學(xué)反射系數(shù)計(jì)：在531nm~570nm波段之間測(cè)定葉反射系數(shù)。該參數(shù)對(duì)類胡蘿卜素極為敏感，反應(yīng)植物的光合作用中的光能利用效率和CO2同化速率，并可作為植物水脅迫的可靠指數(shù)。因此廣泛用于植物產(chǎn)量和脅迫研究。

■NDVI 310植物歸一化植被指數(shù)計(jì)：用來測(cè)定NDVI（一種植物體葉綠素重要的指標(biāo)），在660nm~740nm波長處比較反射光。葉綠素會(huì)強(qiáng)烈吸收紅光用于光合作用，而葉片細(xì)胞結(jié)構(gòu)會(huì)強(qiáng)烈反射近紅外光。因此，NDVI與光合能力直接相關(guān)，從而反映植物冠層的能量吸收狀況。

應(yīng)用領(lǐng)域：
