Seedling raising device capable of regulating intensity and angle of received light

Abstract

The invention relates to technical field of energy and particularly discloses a seedling raising device capable of regulating intensity and angle of received light. The device comprises a supporting frame, a control box, and an upright post, wherein culture box cases for raising seedlings are arranged on the supporting frame; the control box is arranged on the supporting frame, and a horizontal motor which controls the horizontal rotation of the supporting frame, an axial motor which controls the vertical rotation of the supporting frame, two motor drivers which are connected with the horizontal motor and the vertical motor respectively and a controller which is connected with the two motor drivers are arranged in the control box; the control box can be connected with a computer for controlling the rotation rate and pitch swing angle of the supporting frame; and the upright post is arranged below the control box for supporting the supporting frame and the control box. In the device, the top layer is kept under optimal illumination all the time because of the automatic light tracing function of the device; and through the rotation and pitch swing of the device, leaves in different directions and different parts of the same leaf receive the same light, so the optimal photosynthesis is realized.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a seedling raising device capable of automatically regulating the intensity and angle of light received by crops. Background technique [0002] At present, some devices that use or collect solar energy can track the sun, and obtain solar energy completely by keeping the incident light perpendicular to the sun. The power generation of such sun-tracking devices is 30% to 35% higher than that of non-tracking devices, which means , Tracking devices have the potential to improve crop photosynthesis. In crop planting and production, the leaves of crops have unique requirements on the intensity of solar radiation, the angle of sunlight and the photoperiod: when the intensity of sunlight at noon is too high, crops often have photosynthetic lunch breaks and transpiration lunch breaks, which have a negative impact on crop production. Negative impact: due to the changing angle of incidence...

AI Technical Summary

Problems solved by technology

In the production of crops, the leaves of crops have unique requirements on the intensity of solar radiation, the angle of sunlight and the photoperiod: when the intensity of sunlight at noon is too high, crops often have photosynthetic lunch breaks and transpiration lunch breaks, which have a negative impact on crop production. Negative impact; due to the changing angle of incidence of the sun, the shading between leaves of crops in different directions and between leaves makes different leaves and different parts of them unable to receive light evenly, and the best light cannot be obtained, and the potential of photosynthesis of crops is often not fully utilized; At the same time, the growth and development and morphogenesis of crops also require specific photoperiods.

However, in the existing field of crop cultivation, crops can only passively receive sunlight, so photosynthetic lunch breaks inevitably occur, which not only affects the growth of crops, but also wastes energy
