Embodiment 3

[0055] Example 3 Using the device 1 for the intelligent precise lighting energy-saving method for artificial light cultivation of plants

[0056] Refer to Embodiment 1 for the device used in this embodiment for the intelligent and precise lighting energy-saving method for plant artificial light cultivation.

[0057] A total of 24 small rapeseeds were planted in 4 rows of 6×4 under the light source frame, and the position and the light source-lens unit 3 on the light source frame formed a one-to-one relationship.

[0058] Manual manual adjustment, the specific steps are as follows:

[0059] 1) When the canopy area of ​​the small rapeseed plant is small, adjust the power supply to make the artificial light source smaller, adjust the lifting mechanism to make the light source stand and the plant canopy shorter (10cm), adjust the distance between the focusing lens and the artificial light source (5cm) ), so that the spot size (diameter 4cm) formed by the light emitted through the focusing...

Abstract

The invention provides an intelligent precision lighting energy saving method during plant cultivation by using artificial light. The method comprises the following steps: A, adjusting the intensity of an artificial light source; B, adjusting the distance from the artificial light source to plant canopies; C, performing focusing on focusing lenses which are arranged on the artificial light source to control the size of spots of the artificial light source projected to the plant canopies through the focusing lenses, wherein the artificial light source with as low intensity as possible is arranged at a proper distance above the plant canopies through collaborative operation of C and A as well as/or B, so that the light emitted through the focusing lenses is projected to the plant canopies with the light intensity capable of meeting the requirement on plant growth, and as few formed spots as possible are projected to gaps among plants on the premise that the spots have the size to fully cover the plant canopies. The invention also provides a device for the precision lighting energy saving method. The device mainly comprises a light source rack, a lifting mechanism, light source-lens units and a power supply. According to the method, precise lighting range and intensity are provided for the plants, and the waste of light energy during cultivation is greatly avoided.

Description

Technical field [0001] The invention relates to the field of facility cultivation, in particular to a method and device for plant artificial light cultivation, intelligent precise lighting and energy saving. Background technique [0002] Studies have shown that appropriate supplementation of light can speed up plant growth and improve its quality, and at the same time have the effects of regulating its light morphology and flowering period. With the development of plant factory technology and people's pursuit of high-quality vegetables and flowers, more and more plant factories that fully use artificial light for vegetable and flower cultivation are being built and put into operation. [0003] Regardless of whether the plants are planted using substrate cultivation techniques, hydroponic cultivation techniques or aerosol cultivation techniques, and whether they are planting seedlings, planting in the early stage of plant growth, or planting in the later stage of plant growth, suffi...
