Description

Technical Field

[0001] This utility model relates to the technical field of plant growth research devices, and more specifically, to a light regulation device for studying the effects of light on plant growth. Background Technology

[0002] Plant growth and development are influenced by a variety of environmental factors, among which light is one of the most important external factors. Light not only provides plants with the energy needed for photosynthesis, but also regulates their growth process, flowering time, yield and quality by influencing the photomorphogenesis and physiological activities of plants. The specific effects of light are not only related to light intensity, but also closely related to light quality (i.e., the wavelength distribution of light). For example, red light, blue light and ultraviolet light have different physiological effects on plant growth.

[0003] In the study of plant photosynthesis, it is necessary to explore the effect of light on the rate of photosynthesis by adjusting light quality and light intensity; in the study of plant morphogenesis, it is necessary to precisely control the spectrum to study the regulatory mechanisms of specific wavelengths on plant morphology and physiology.

[0004] In the existing technology, although some devices can adjust the light quality or light intensity through filters or other optical elements, these devices mostly adopt the method of manually changing filters or fixing the light source, which has problems such as complicated operation, low experimental efficiency, and difficulty in repeatedly controlling the light conditions. In addition, the existing devices can only study the plant growth under specific conditions at a single point and lack the ability to conduct multiple parallel experiments, making it impossible to conduct comparative studies at the same time, which limits the accuracy of experimental results.

In addition, a plurality of planting slots are formed on the circular base, and each planting slot is provided with an independent glass sheet, so that multiple experiments can be compared in one device, thereby effectively improving the experimental efficiency and research breadth and ensuring the accuracy of the experiment.

[0013] Compared with the prior art, the above technical solution can ensure the stability of the fixed bearing base and drive the fixed plate to rotate by the rotation rod, thereby realizing the rotation switching of the glass sheet.

[0014] In a possible implementation, each rotation device further includes a positioning cylinder, each positioning cylinder is arranged on the outer sidewall of the circular base and located above each bearing base, and each positioning cylinder is sleeved on the outside of each rotation rod.

[0015] Compared with the prior art, the above technical solution can further improve the stability of the entire device by installing the positioning cylinder on the outside of the rotation rod.
