Problems solved by technology

With this method of supplementary light, the light is from top to bottom, and mostly irradiates the leaves of the upper canopy of the crops, while the leaves between the clumps and the inner groups of the plants below the canopy of the plants cannot get enough light.
In addition, the implementation of fixed-point continuous light supplement for plants is not the most efficient means of supplement light

Abstract

The invention discloses a greenhouse light replenishing device with a movable light source. The device comprises rails, a trolley which moves on the trolley, two movable arms which are arranged on the trolley and can extend towards an upper surface and side surfaces, and light replenishing lamps which are installed on the movable arms. Each movable arm comprises a retractable arm which is vertically on the trolley and can be adjusted upwards and downwards, and a swing arm which is hinged with the upper end of the retractable arm, can form a certain angle with the retractable arm and can extend outwards. The light replenishing lamps are arranged on the external sides of the swing arms. The greenhouse light replenishing device with the movable light source can realize vertical light replenishing, horizontal light replenishing and light replenishing at any angle of inclination according to cultivation requirements, the light replenishing effect is improved and the device can be freely adjusted and controlled; and variable light replenishing can be implemented to plants according to the light replenishing demand of plant growth through the trolley which automatically moves on the rails. The light replenishing device has the advantages of simple structure, low cost, labor saving, extremely high universality and promising market prospect.

Description

technical field [0001] The invention relates to an agricultural instrument, in particular to a greenhouse lighting supplementary device with a moving light source. Background technique [0002] In recent years, with the rapid development of greenhouse cultivation, the total area of ​​greenhouses has exceeded 50 million mu, and the regulation of the light environment of greenhouse plants has gradually attracted widespread attention. Photosynthesis is a life activity that plants rely on for survival. Plants convert carbon dioxide and water into carbohydrates by using light energy. Illumination is closely related to the growth of crops. Capturing light energy to the maximum extent and giving full play to the potential of plant photosynthesis will directly affect the benefits of agricultural production. In recent years, due to the promotion of market demand, greenhouses are widely used to produce off-season flowers, fruits, vegetables, etc. Due to the short sunshine time in win...
