Problems solved by technology

Both of the above two patents only involve the combination of red, blue and purple light tubes with wider wavelengths, and neither of them mentions the light intensity (ie, the peak light energy) and the green light range, while the light irradiation of different light intensities The effect on plant growth and composition is also different, so its effect on promoting plant growth and development is limited

Embodiment Construction

[0010] The optimal wavelength and light energy peak range of the plant growth regulating lamp of the present invention will be determined by the light irradiation on seed germination and growth experiments of the control substance and the fifth generation of the plant growth regulating lamp of the present invention. Take, for example, the relatively inexpensive fluorescent lamps manufactured based on the following wavelengths and peak luminous energy.

[0011] Control substance:

[0012] OSRAM FLORA L30-77;

[0013] The selection of plant growth regulating lamp wavelength of the present invention:

[0014] The first generation-S1: 380nm=25%, 420nm=75%, 535nm=60%, 660nm=95%;

[0015] The second generation-S2: 410nm=25%, 440nm=50%, 545nm=90%, 660nm=100%;

[0016] Third generation-S3: 400nm=20%, 430nm=30%, 545nm=75%, 660nm=100%.

[0017] Experimental method: Each group puts one seed of the same plant in four flowerpots (soak the seeds in water at 45°C for 30 minutes), cultiva...

Abstract

The invention discloses a plant growth adjusting lamp, which is characterized in that: a mixed spectrum of the lamp comprises a spectral wavelength of 440+ / -20nm and a light energy peak of 93+ / -7 percent, a spectral wavelength of 550+ / -20nm and a light energy peak of 90+ / -5 percent, a spectral wavelength of 660+ / -30nm and a light energy peak of 95+ / -5 percent and a spectral wavelength of 415+ / -5nm and a light energy peak of 50+ / -15 percent. The lamp is a fluorescent lamp, a high-frequency / low-frequency electroless lamp or a light-emitting diode (LED) lamp. The lamp can greatly shorten plant seed germination time and mature time, and is low in energy consumption and low in cost.

Description

technical field [0001] The invention relates to a plant growth regulating lamp with a specific mixed spectrum that can promote the emergence and growth of plants. Background technique [0002] Plants need to carry out photosynthesis to provide the nutrients they need for their own growth, and the influence of light on plants is very important. The spectrum of sunlight is continuous and contains a huge spectral width, while plants only need to absorb a small part of it, and the absorption of sunlight is mainly concentrated in the visible part. The details are as follows: Chlorophyll-a, 435±15nm, low light energy 555±15nm, 660±15nm (mixed light pixel unit); chlorophyll-b, 455±10nm, low light energy 550±10nm, 640±10nm (mixed light pixel unit); β-carotene, 450±10nm, 475±10nm, low light energy 555±15nm and 640±10nm (mixed light pixel unit); red plants grow mainly with higher blue light energy, There are similarities with the spectrum of β-carotene, and there are also required o...
