Abstract

The invention discloses a fluorescent powder composition capable of promoting rapid growth of algae and application thereof, which is characterized in that (Y<1-x>Cex)3Al5O12 fluorescent powder, Ca<1-y>SryAlSiN3: 0.015Eu<2+> fluorescent powder and (Al<1-c>Gac)2O3: zCr<3+> fluorescent powder are mixed according to a certain proportion, and after the mixed powder is excited by 420-480nm blue light,the fluorescent powder Ca<1-y>SryAlSiN3: 0.015Eu<2+> emits red light with a main peak wavelength of 645-660 nm, green light emitted by the fluorescent powder (Y<1-x>Cex)3Al5O12 is just absorbed by thefluorescent powder (Al<1-c>Gac)2O3: zCr<3+>, dark red light with the wavelength of 680-693 nm is emitted, and finally, the fluorescent powder combination emits a combined spectrum with the main peakwavelengths of 645-660 nm and 680-693 nm, so that very strong dark red emission is generated, and a light conversion effect is achieved. According to the fluorescent powder combination, green light which cannot be absorbed by chlorophyll in single fluorescent powder (Y<1-x>Cex)3Al5O12, Ca<1-y>SryAlSiN3: 0.015Eu<2+> and (Al<1-c>Gac)2O3: zCr<3+> is converted into dark red light which has remarkableinfluence on plant photosynthesis and photoperiod effect, the light energy utilization rate of algae can be remarkably increased when the fluorescent powder combination is prepared into a lamp bead ora light supplementing lamp to irradiate the algae, and the growth of the algae is promoted.

Description

technical field [0001] The invention belongs to the technical field of growth regulation of algae plants, and relates to a fluorescent powder combination that can promote the rapid growth of algae plants, and also relates to an application method of the fluorescent powder combination. Background technique [0002] Most algal plants live in water, with simple structure, no differentiation of roots, stems, and leaves, and cells containing chloroplasts, such as Chlorella, Chlorella, a genus of single-celled green algae of the Chlorella phylum, is a spherical single-celled freshwater Algae; Chlamydomonas is a single-celled algal plant with a cup-shaped chloroplast in the cell; Spirogyra is a multi-cellular algal plant with ribbon-shaped chloroplasts in the body; kelp and Gemweed have spindle-shaped chloroplasts in the body. However, some prokaryotic algae such as cyanobacteria do not form a double-membrane-coated structure in their cells, and the structure carrying chlorophyll i...
