Embodiment

[0038] Please refer to figure 1 and figure 2, this embodiment provides a photosynthetic rate measuring device 100 . The photosynthetic rate measuring device 100 includes an assimilation chamber 110 , a fan 120 and a motor 130 .

[0039] The side wall 111 of the assimilation chamber 110 encloses an assimilation cavity 112 . The assimilation chamber 112 is provided with a mesh plate 140 connected to the side wall 111, and the mesh plate 140 divides the assimilation chamber 112 into a first chamber 112a and a second chamber 112b. The side wall 111 defines an air inlet 111a communicating with the first cavity 112a and an air outlet 111b communicating with the second cavity 112b. The air inlet 111a is located at an end of the first cavity 112a close to the mesh plate 140 . Both the gas inlet 111a and the gas outlet 111b are used to communicate with the analysis device. The fan 120 is in drive connection with the motor 130 , both the fan 120 and the motor 130 are accommodated ...

Abstract

The invention discloses a device and a system for measuring photosynthetic rates, and relates to the field of technologies for measuring photosynthetic rates of fruits. The device for measuring the photosynthetic rates comprises an assimilation chamber, a fan and a motor. An assimilation cavity is enclosed by a side wall of the assimilation chamber. The assimilation cavity is provided with a net plate connected with the side wall, and the assimilation cavity is divided into a first cavity and a second cavity by the net plate. A gas inlet which is communicated with the first cavity and a gas outlet which is communicated with the second cavity are formed in the side wall. The gas inlet is formed in the end, which is close to the net plate, of the first cavity. The fan is in transmission connection with the motor, the fan and the motor are accommodated in the first cavity, and the fan is positioned on the side, which is close to the net plate, of the motor. The motor is slidably arranged on the first cavity, so that the fan can be get away from the net plate and can approach the net plate. The system for measuring the photosynthetic rates comprises an analysis device and the device for measuring the photosynthetic rates. The gas inlet is communicated with a reference gas outlet of the analysis device, and the gas outlet is communicated with an analysis gas inlet of the analysis device. The device and the system have the advantages that the device and the system can be used for measuring the photosynthetic rates of fructus schisandrae chinensis and are convenient to use and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of photosynthetic rate measurement, in particular to a photosynthetic rate measurement device and a photosynthetic rate measurement system. Background technique [0002] Schisandra chinensis (Turcz.) Baill. is a perennial woody vine medicinal plant of Magnoliaceae (Magnoliaceae), mainly distributed in Northeast my country, Russian Far East and Korean Peninsula. The dried fruit of Schisandra chinensis, which is mainly produced in Northeast my country and parts of Hebei Province, is commonly known as "Northern Schisandra", which has been recorded in "Shen Nong's Materia Medica" and "Compendium of Materia Medica", and is one of the rare and authentic medicinal materials in my country. It has the functions of nourishing qi, nourishing the kidney, promoting body fluid, and calming the nerves. It is mainly used to treat thirsty wounds, neurasthenia, palpitations, insomnia, and dreaminess. At present, in addition t...
