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 optimum wavelength and light energy peak range of the plant growth adjusting lamp of the present invention are determined below through experiments on seed germination and growth of the reference substance and the fifth-generation product of the plant growth adjusting lamp of the present invention. Take, for example, a relatively inexpensive fluorescent lamp based on the following wavelengths and peaks of light energy.

[0011] Controls:

[0012] OSRAM FLORA L30-77;

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

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

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

[0016] 3rd Generation-S3: 400nm=20%, 430nm=30%, 545nm=75%, 660nm=100%.

[0017] Experimental method: Each group placed one seed of the same plant in four flowerpots (the seeds were soaked in water at 45°C for 30 minutes), cultivated in a darkroom...

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 which 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 impact of light on plants is crucial. The spectrum of sunlight is continuous and contains a large spectrum width, while plants only need to absorb a small part of it, and the absorption of sunlight is mainly concentrated in the visible light 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, Similar to the β-carotene spectrum, there are also required ones such as phycoerythrin ...
