Embodiment 1

[0053] Such as figure 1 As shown, the LED light source 10 is placed in front of the plant leaves or other photosynthetic receptors to radiate light to the plants, and the light 20 that does not pass through the light-transmitting material passes through royal blue, blue or dark blue as the light-transmitting material 30. The wavelength is filtered by the plastic cloth or the woven net, and the light 40 passing through the light-transmitting material is irradiated on the plant 50 , and can be adjusted or reserved to a suitable spectral range to promote plant growth.

[0054] After the light source passes through the blue and green light-transmitting materials, its spectrum changes as follows: figure 2 , image 3 As shown, it can be seen that the light source has two peaks after passing through the blue light-transmitting material.

[0055] In a preferred embodiment, after the light source passes through the light-transmitting material of the present invention, the adjusted o...

Embodiment 2

[0057] The Phalaenopsis seedlings are placed under the general black woven net, and the light quantity received by the light source system in the full spectrum wavelength range is reduced in equal proportion; another group of Phalaenopsis seedlings is placed on the royal blue plastic cloth or woven net of the present invention, and received The light source adjusted or retained by the light-transmitting material, as a result, the growth period of the seedlings placed in the black woven net is 16 weeks, and the growth period of the seedlings placed in the royal blue plastic cloth of the present invention or the woven net is shortened by 1-2 weeks; The acclimatization period of the Phalaenopsis orchids with royal blue plastic cloth or woven nets is also shortened by 1-2 weeks compared with the Phalaenopsis orchids with black woven nets.

Embodiment 3

[0059] An embodiment of the light accumulation calculation device 100 of the present invention is Figure 5 As shown, it includes: a spectral sensing unit 101, used to measure a light quantity data in a spectral wavelength range; a spectral multi-band setting module 102, connected to the spectral sensing unit 101, to sense the spectral The unit 101 performs full-band or multi-band wavelength setting within the spectral wavelength range; a light amount accumulation calculation module 103 is connected to the spectral sensing unit 101, and the light amount data measured by the spectral sensing unit 101 Accumulated and calculated into a cumulative light quantity data; a data processing unit 104, connected to the light quantity cumulative calculation module 103, for processing, recording, and storing the cumulative light quantity data; and a control unit 105, connected to the spectrum multi-band setting module 102 and the data processing unit 104 for controlling the settings of the...

Abstract

The present invention provides a method for stimulating plant growth, which comprises: (a) placing a light transmissive material for adjusting or retaining light spectrum wavelengths below 500 nm (section A), between 500~630 nm (section B), and above 630 nm (section C) between the light and a photosynthesis receptor of the plant; and (b) providing the illuminance or photon flux density of section B lower than that of section A or section C after the light passing through the light transmissive material. The present invention also provides an apparatus and methods for computing cumulative light quantity, comprising (a) a spectrum sensing unit; (b) a spectrum multi-band setting module; (c) a cumulative light quantity computing module; (d) an information processing unit; and (e) a control unit.

Description

technical field [0001] The present invention relates to a method for promoting plant growth. The present invention also relates to a light accumulation calculation device and method. Background technique [0002] Photosynthesis is the process by which plants and other self-supporting organisms convert light energy (usually from the sun) into chemical energy that can be used to fuel the activities of living organisms. During this process, carbohydrates such as sugars are synthesized from carbon dioxide and water. Oxygen is also released, mainly as waste. The process by which most plants, most algae, and blue-green algae carry out photosynthesis is known as photosynthetic autotrophs. Photosynthesis maintains the oxygen content of the atmosphere and provides most of the energy required by all life on Earth (except chemotrophic organisms, which obtain energy through oxidative chemical reactions). [0003] Although photosynthesis is handled differently in different species, t...
