主要功能及特色

Gas exchange measurement is an effective method for studying the photosynthetic capacity at the leaf scale of plants. This instrument measures gas exchange parameters of horticultural plants, crops, and other plant leaves, such as photosynthetic rate, transpiration rate, and chlorophyll fluorescence parameters. This research helps to understand the physiological and ecological characteristics of plants, providing scientific guidance and strong support for the analysis of photosynthetic physiological traits, trait analysis, and the selection of superior crop varieties, as well as the study of environmental tolerance mechanisms.

气体交换测量是研究植物叶片尺度的光合能力的有效方法。该仪器通过测量园艺植物、农作物等植物叶片的气体交换参数，如光合速率、蒸腾速率、叶绿素荧光参数等指标，以此研究植物的生理生态特性，对植物的光合生理特征、性状分析以及优良作物品种筛选、耐受环境机制研究起到科学的指导作用和强有力的科研支撑。
