Abstract

The invention provides a plant population photosynthesis measuring device and a measuring method, the device comprises a base and a closed static box which are arranged in cooperation, and the closedstatic box is arranged on the base and is in sealed connection with the base; the closed static box comprises a top end static box and one or more lengthened static boxes, and the top end static box and the lengthened static boxes are detachably connected in a sealed mode; a photosynthetic instrument is provided, wherein the photosynthetic instrument is connected with the closed static box to forma closed loop so as to determine the photosynthesis of the plant population. According to the technical scheme of the invention; the photosynthetic instrument is ingeniously combined with the staticbox; the photosynthesis of the plant population can be efficiently, conveniently and accurately determined; and the lengthened static boxes are designed and can be designed into a series of differentlengths and models, so that the group photosynthesis of various types of plants at different growth stages, such as herbaceous plants, gramineous plants and small-sized shrub plants, can be conveniently measured, and the application range of measuring the group photosynthesis is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of plant photosynthesis detection, in particular to a plant population photosynthesis measurement device and a plant population photosynthesis measurement method. Background technique [0002] Photosynthesis is the sum of a series of complex metabolic reactions, the basis for the survival of organisms in nature, and an important medium for the earth's carbon-oxygen balance (that is, the balance of carbon dioxide and oxygen). Accurately quantifying the photosynthesis process of plants can deepen the understanding of plant photosynthesis and provide basic data support for the construction of global carbon cycle models. Because plants have different plant physiological and ecological characteristics in different growth stages, the photosynthesis intensity of plants in different stages and the related plant respiration intensity and transpiration rate will be significantly different. Even at the same stage, lea...
