Multiband agricultural plant lighting device

Abstract

The invention provides a multiband agricultural plant lighting device. The device comprises a support frame, a folding bracket and a stretching bracket. A plurality of containing grooves are formed inthe surface of one side of the support frame in a length direction. The folding bracket is embedded into the containing grooves; one end of the folding bracket is hinged with one tail end of the inner side of the containing groove; the rotating plane of the folding bracket is perpendicular to the width direction of the containing groove. A through groove is formed in the side face, away from thesupport frame, of the folding bracket in the length direction. The stretching bracket is embedded in the through groove and slides in the length direction of the through groove, a plurality of ultraviolet LEDs are arranged on the face, provided with the containing grooves, of the support frame in an array mode, a plurality of blue light LEDs are arranged on the face, away from the support frame, of the folding bracket in an array mode, and a plurality of red light LEDs are arranged on the face, away from the folding bracket, of the stretching bracket in an array mode. According to the invention, morphological adjustment can be carried out according to different age groups of plants, so that a better irradiation effect is achieved, and plant growth is promoted.

Description

technical field [0001] The invention relates to the technical field of plant cultivation devices, in particular to a multi-band agricultural plant lighting device. Background technique [0002] Light is an essential source of energy for plant growth, and it regulates photosynthesis, growth and development, morphogenesis, and material metabolism of plants. However, only about 5% of sunlight can have an effect on photosynthesis. At present, blue light and red-orange light contribute the most to photosynthesis. [0003] Blue light can promote the synthesis of plant protein, and has a greater impact on the growth of plants and the formation of young shoots. It can inhibit the elongation of plants and make plants form a fancy root shape. It can also assemble cell differentiation, which is beneficial to anthocyanins and vitamins. Synthesis. Red-orange light is beneficial to the synthesis of plant carbohydrates, accelerates the development of plant stem nodes, and converts exces...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, it is widely used to improve the growth effect of plants by adding lighting equipment, but the lighting equipment is simple and single, and the method of hanging light bulbs is often used to increase the light, which makes the utilization rate of light by plants low, and plants The stems and leaves in the middle are difficult to receive top light. At the same time, when the plant grows and changes in shape, the position of the lighting equipment is not easy to change, so it cannot adapt to the growth of the plant.
