Embodiment Construction

[0012] The plant physiological function display device of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] As shown in the figure, the plant physiological function display instrument of the present invention includes a base 8, a transparent bell jar 7, a transparent tube 3, a U-shaped tube 2, a buffer box 9, a hygrometer 10, a storage battery 11, a light box 1, a thermometer 5 and a timer 4. The base 8 is a plank on which a transparent bell jar 7, a thermometer 5 and a timer 4 are installed respectively. The junction of the base 8 and the transparent bell 7 is provided with a corresponding circle of grooves, and the periphery of the bottom of the transparent bell 7 is set in the groove. In order to have better sealing between the two, between the groove and The contact surface of transparent bell jar 7 is coated with vaseline. The transparent bell jar 7 and the transparent tube 3 are made of glass, and the transp...

Abstract

The invention discloses a plant physiological effect indicator. The plant physiological effect indicator which comprises a pedestal, a transparent bell cover, a transparent tube, a buffering agent box, a humidity measurer and a U-shaped tube is characterized in that: the transparent bell cover which is arranged on the pedestal is communicated with one end of the U-shaped tube through a glass tube, and the other end of the U-shaped tube is open; the buffering agent box which is arranged in the glass bell cover is provided with a carbon dioxide buffering agent therein; the humidity measurer is arranged in the glass bell cover; and corresponding zero scales are marked on the bottom of two sides of the tube wall of the U-shaped tube, and a colored liquid column which is arranged in the U-shaped tube is arranged under the zero scales of the U-shaped tube. The carbon dioxide buffering agent preferably selects a NaHCO3/H2CO3 buffering agent. The plant physiological effect indicator which allows intensities of photosynthesis, respiration and transpiration in the growth of plants to be effectively and visually observed has the advantages of simple operation and low cost.

Description

technical field [0001] The invention relates to a plant physiological function display device, in particular to a display device capable of directly observing plant photosynthesis, respiration and transpiration. Background technique [0002] During the normal growth process, plants have both photosynthesis and respiration, and transpiration at the same time; in addition to transpiration at night, plants only perform respiration. When demonstrating the physiological effects of plants, it is necessary to use different equipment and devices to compare and demonstrate respectively, which costs a lot of materials, troublesome operation, and the phenomenon is not obvious enough. [0003] In the prior art, there is a plant photosynthesis measuring instrument (patent number: 200520111943.8), which is mainly designed for the needs of plant photosynthesis and respiration experiments. The photosynthesis meter can measure the photosynthesis of plant leaves in vitro or in vivo, and dire...
