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.
