Embodiment 1

[0048] Embodiment 1 is used for the laser beam diverging device of A and the plant cultivation method using the device

[0049] A laser beam diverging device for A, the structure of which is as figure 1 As shown, it is composed of a laser emitter 1, a pattern lamp holder 2 located below it, and a uniform light plate 8.

[0050] Laser emitter 1 can be provided with several sets according to the kind of laser used (N kinds of laser just use N sets). The laser emitter 1 used in this embodiment is two, a red light (660nm) laser emitter and a blue light (460nm) laser emitter, its photo is shown in figure 2 , where the left side of the photo is a blue laser transmitter with a specification of 500MW, and the right side of the photo is a red laser transmitter with a specification of 500MW. The blue laser beam and the red laser beam respectively emitted by the two laser emitters converge at the gobo lamp head.

[0051] The pattern lamp head used in this embodiment is a commercially...

Embodiment 2

[0055] Embodiment 2 is used for the laser beam diverging device of B1 and the plant cultivation method using the device

[0056] For the laser beam diverging device used in B1, its structure diagram is shown in image 3 , consisting of a laser transmitter 1, a straight lens 3, a mirror 4 and a motor 5 that drives the mirror to reciprocate and swing; the laser beam emitted by the laser transmitter 1 is converted into a linear light band by the straight lens 3, and then projected onto the On the reciprocating mirror 4, after reflection, a reciprocating scanning light band is formed below.

[0057] The photo of the used reflector 4 and the motor 5 that drives the reflector to swing back and forth in this embodiment is shown in Figure 4 .

[0058] The present embodiment has used 3 kinds of laser beam source configurations (3 kinds of laser emitter configurations):

[0059] a red laser beam (a red laser transmitter)

[0060] b Combination of red laser beam and blue laser beam ...

Embodiment 3

[0067] Embodiment 3 is used for the laser beam diverging device of B2 and the plant cultivation method using the device

[0068] For the laser beam diverging device used in B2, its structure diagram is shown in Figure 7 , consists of a laser transmitter 1, a straight-line lens 3, a polygonal mirror 6 and a motor 5 that drives the rotation of the polygonal mirror; the laser beam emitted by the laser transmitter 1 is converted into a linear light strip by the straight-line lens 3, and then projected onto the rotating polygonal mirror 6, after reflection, a repeated scanning light band is formed below.

[0069] The polygonal mirror used in this embodiment is a hexagonal mirror, which can be replaced with other polygonal mirrors that can achieve the same scanning effect.

[0070] Carry out 3 kinds of laser beam light source configurations with reference to embodiment 2, detect the light band that produces and set the cultivation plate position, its requirement also refers to emb...

Abstract

The invention relates to the field of facility cultivation, and particularly provides a plant-cultivating method after laser-beam divergence. The plant-cultivating method is a method that after being diverged, a laser beam is projected to a plant canopy layer. The divergence is selected from anyone of divergence in space, divergence in space and time and divergence in space and energy level. According to the plant-cultivating method after the laser-beam divergence, aiming the characteristics that a larger number of photons in a laser are projected in an extremely small space range, and the energy density is extremely high, the laser beam is dispersed, and then is projected to the plant canopy layer; by using the characteristics that the laser has an almost singular wave length, and even after being transmitted through a long distance, the intensity and the waveform of the wave length can still be maintained, the aim that the growth requirement of a large number of plants can be guaranteed by using a small number of laser beams is achieved, the light energy use ratio is high, the ratio for converting light energy into thermal energy during the cultivating process is small, and by carrying out simple heat dissipation, the energy consumption during the plant cultivating process is greatly lowered.

Description

technical field [0001] The invention relates to the field of facility cultivation, in particular to a method for cultivating plants after laser beams diverge. Background technique [0002] With the development of facility agriculture in our country, artificial light is more and more widely used in the large-scale cultivation of vegetables and other crops. Its environmental factors are controllable, the land utilization rate is high, and it can be produced according to the plan. It is in line with the development of modern agriculture. The essential requirements will be an important means to solve problems such as population growth, resource shortage, new generation labor shortage, and rising food demand in the future, and it has attracted widespread attention from all over the world. [0003] At present, the artificial light sources used under different facility cultivation conditions are mainly high-pressure sodium lamps and fluorescent lamps, etc., and their light-emitting...
