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)的野外便攜式儀器空間廣闊,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)定葉綠素含量提供深度撮合服務,和其他重要的特征服務品質。有兩個(gè)標(biāo)準(zhǔn)版本光化學(xué)反射系數(shù)(Photochemical Reflectance Index的發生,PRI)和歸一化植被指數(shù)(Normalized Difference Vegetation Index,NDVI)影響。整合了藍(lán)牙技術(shù)(藍(lán)牙模塊或USB軟件狗)新的動力,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)用戶需要發展契機,還可提供定制服務(wù)廣泛關註。
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發力,反應(yīng)植物的光合作用中的光能利用效率和CO2同化速率鍛造,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)量和脅迫研究持續創新。
■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))改善,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協調機製,而葉片細(xì)胞結(jié)構(gòu)會(huì)強(qiáng)烈反射近紅外光信息化。因此,NDVI與光合能力直接相關(guān)向好態勢,從而反映植物冠層的能量吸收狀況平臺建設。
應(yīng)用領(lǐng)域:
■快速測(cè)量葉綠素含量;
■植物生物學(xué)貢獻力量;
■植物篩選和野外研究使用;
■脅迫生理學(xué);
