A lighting device that can effectively promote the vegetative growth of Arabidopsis

Abstract

The invention discloses an illumination device capable of effectively promoting nutritious growing of arabidopsis thaliana, and relates to a plant culturing illumination device. A plant culturing frame, neutral light fluorescent light tubes, neutral light fluorescent light frames, UV-B light tubes, UV-B light frames, a planting box, a timer and a thermometer. Four layers of the planting culturingframe is arranged, the size of the planting culturing frame is adjusted according to the floor occupation area of a cultured plant; the neutral light fluorescent light tubes are arranged on the neutral light fluorescent light frames, the UV-B light tubes are arranged on the UV-B light frames, the neutral light fluorescent light frames are arranged on the tops of each layer of the plant culture frame, the UV-B light frames are arranged at the bottoms of the neutral light fluorescent light frames, and the neutral light fluorescent light tubes and the UV-B light tubes are independently controlledby the timer to provide different light sources for the growing of the arabidopsis thaliana; the thermometer is arranged on the side face of the plant culturing frame, the plant culturing box is arranged on the plant culturing frame and used for planting the arabidopsis thaliana, and therefore the arabidopsis thaliana is allowed to be in a certain nutritious environment.

Description

technical field

[0001] The invention relates to a lighting device for plant cultivation, in particular to a lighting device which can effectively promote the vegetative growth of Arabidopsis thaliana. Background technique

[0002] In agricultural production, in order to meet production requirements, people have replaced sunlight with artificial light sources for a long history. At the same time, with the advancement of science and technology, the rapid development of fluorescent tube technology has made it a reality to cultivate plants indoors. At present, fluorescent tubes are widely used in various fields such as agricultural production, scientific research and teaching. Studies have shown that in the spectrum accepted by plants, it can be divided into UV light, blue light, red light and far red light according to wavelength ([1]. Heijde, M. and R. Ulm, UV-B photoreceptor-mediated signaling in plants. Trends Plant Sci, 2012.17(4): p.230-237). Blue and red fluorescent tub...
