Embodiment 1

[0022] Treatment group: eg figure 1 , a device for cultivating plants, comprising an LED light source board 3, a plant 5, a cultivation tank for placing the plant 5, and a cultivation frame 1 for the LED light source board 3, the LED light source board 3 is located above the plant 5, and the vertical support of the cultivation frame is installed with Vertical guide rail 2, horizontal guide rail is installed on the horizontal support. The LED light source board 3 is kept at a certain height above the plant 5 by the traction of the motor, and moves upward when the plant 5 grows tall. In this embodiment, the control LED light source board is located 5 cm above the plants. The same area of ​​plants was irradiated with the same area of ​​light board (light source board) as that of the control group. The device is placed in a plant factory, placed in multiple layers.

[0023] Control group: the light source board with the same area as the plant cultivation area was fixed at 25cm ...

Embodiment 2

[0027] Treatment group: eg figure 1 , a device for cultivating plants, comprising an LED light source board 3, a plant 5, a cultivation tank for placing the plant 5, and a cultivation frame 1 for the light source board, the light source board 3 is located above the plant 5, and a vertical guide rail 2 is installed on the vertical support of the cultivation frame , the horizontal guide rail is installed on the horizontal support. The LED light source board 3 per unit area is located 15 cm above the plant 5. It moves horizontally once every 10 hours and turns off, and then turns on the lighting again after 2 hours. The moving distance is the length of one LED light source board 3, so that it can illuminate the 2 plants below in turn. Plants 5 times the area of ​​the light source board. The device is placed in a plant factory, placed in multiple layers.

[0028] Control group: the light source panel with the same area as the plant cultivation area was fixed at 15cm above the pl...

Embodiment 3

[0032] Treatment group: eg figure 1 , a device for cultivating plants, comprising an LED light source board 3, a plant 5, a cultivation frame 1 for placing the plants and the light source board, the LED light source board 3 is located above the plant 5, a vertical guide rail 2 is installed on the vertical support of the cultivation frame, and a horizontal support Horizontal guide rails are installed on it. The LED light source board 3 is kept at a certain height above the plant 5 by the traction of the motor, and moves upward when the plant grows taller. In this embodiment, the control light source board is located 5 cm above the plants. At the same time, the light source board moves horizontally once every 10 hours and turns off, and turns on the lighting again after 2 hours. The moving distance is the length of an LED light source board, so that it turns to illuminate the plants below twice the area of ​​the light source board. The device is placed in a plant factory, plac...

Abstract

The invention provides a method for cultivating plants by using an LED (light-emitting diode) light source. The method is characterized in that LED light source plates and the plants are placed on a cultivation rack, the LED light source plates are arranged 2-15cm above the plants and move vertically along with the growth of the plants, and the LED light source plates periodically horizontally move to irradiate the plants below the LED light source plate by turns. The invention additionally provides a device for the method. By using the device provided by the invention, the height of the light source plates can be adjusted, the advantages of an LED lamp cold light source can be exerted and utilized to the utmost extent, the vertical distance between the light source plates and the plants is minimized, the luminous intensity is reduced and the electric quantity is saved; and since the LED light source plates can be adjusted horizontally and a photo stage and a dark stage of plant growth are alternated, the light source plates in unit area can provide light for vegetables with area which is two times of the original area, the normal physiological activities at the photo stage and the dark stage of the plants below are guaranteed and the primary investment in the LED light source plates is halved at the same time.

Description

technical field [0001] The invention belongs to the field of general botany, and specifically relates to a method for cultivating plants by using light and a device used in the method. Background technique [0002] At present, LED plant growth light source technology is developing rapidly. There are many reports about plant growth lights using LED as light source. Each has its theoretical basis and application value, but the application focuses and effects are different. CN1596606 announced a "high-efficiency energy-saving LED plant ecological lamp", which provided a linear transparent resin tubular lamp with simple wiring and low cost; CN102349354A announced an "energy-saving LED lighting Rectify the waveform and turn on or off the output of the drive part to achieve the purpose of improving the power factor and reducing power consumption; CN102418891A announced "an automatic energy-saving LED lamp", which provides a light-sensitive controller instead of manual on and off ...
