PlantPen NDVI 300 植物NDVI测量仪

名称：植物NDVI测量仪         型号：PlantPen NDVI 300         产地：捷克

用途：PlantPen是一款设计精巧、可快速测量植物NDVI指数的便携式仪器可根据反射系数确定植物特征，通过各种反射系数可以评定叶绿素含量。

        NDVI(归一化植被指数)是通过计算植物叶片对660 nm和740 nm两种波长光发射情况计算得到的值，反应植物叶绿素含量的重要参数。一个方便的叶夹、简单的两键操作以及明亮的显示屏使得PlantPen在不干扰调查植物（无叶片脱落或损坏）下仍方便使用。

        测量数据存储于仪器内部，可选择蓝牙（NDVI 300-B）或USB数据线（NDVI 300-U）与计算机连接，使用专业FluorPen软件进行数据传输和可视化分析；可选配GPS模块。

特点：

    设计紧凑、坚固的PRI非常适用于野外环境、植物温室等

    *的手持叶夹，双键操作，LED显示屏设计，使用方便

    非侵入式无损测量

    4节AAA电池供电，方便耐用

    USB或蓝牙传输数据，专业软件进行可视化分析

应用：

    光合作用教学与研究

    植物分子生物学

    植物的筛选和实地研究

    农学与林业

        对于NDVI, Umbilicaria arctica和Umbilicaria hyperborea随着水势的变化有相同的变化趋势，均随着水势降低而降低，但两物种之间存在差异。*水化的U. arctica的NDVI在0.55-0.75之间，U. hyperborea的NDVI比较低，在0.30-0.55之间；脱水后的U. arctica在0.55-0.30之间，而U. hyperborea在0.30-0.15之间。
