Problems solved by technology

[0002] Dragon fruit belongs to the CAM plant, which only blooms at night. The spectrum required for the transition from vegetative growth to reproductive growth cycle is very specific, which leads to the limitation of off-season cultivation of pitaya due to the inability to successfully differentiate flower buds, and it has been difficult to break through
In addition, the effect and mechanism of light quality on the quality and taste of dragon fruit are unknown

Embodiment 1

[0025] Determination of pitaya vegetative growth transition to reproductive growth of phytochrome, cryptophyll, chlorophyll absorption peaks mainly have five wavelengths: respectively 405nm, 450nm, 535nm, 650nm and 730nm, according to the above results experimental design. The light source lamps used are one energy-saving lamp (control group 3) and five kinds of LED strip lights: Scheme 1 is an LED strip light with a specific spectrum; Scheme 2 is an LED strip light with a specific spectrum; Scheme 3 is an LED strip light with a specific spectrum. Strip light (later confirmed as the preferred solution according to the experimental results), control group 1 is an LED strip light with a red-to-blue ratio of 8:1, and control group 2 is an ordinary LED strip light. By adjusting the distance between the light source and the plant, the The quantum flux density of each lamp on the dragon fruit crown is controlled at 7-15μmol / s / M 2 Within the range, and two treatments are set for each...

Embodiment 2

[0035] According to the results of Example 1, according to the spectral formula of the preferred scheme, a dragon fruit flower-promoting LED flexible light strip is made, and its structural schematic diagram is shown in Figure 4 , Figure 5 .

[0036] The flexible copper film substrate 2 used in the dragon fruit flower-promoting, production-increasing, and quality-increasing LED flexible light strip is 3.8mm wide in this embodiment. While reducing the current density, the flexible copper film substrate 2 can improve the heat dissipation capability; there are 28 lamp beads 1 in each meter of the flexible light strip, and the width of the lamp beads 1 used in this embodiment is 2.8mm; Drive to ensure that the quantum flux density PPFD of plant lamp beads is not limited by distance; 24-36V safe voltage input and maintain brightness replaces high-voltage AC cables, improving safety and saving cable costs.

Abstract

The invention belongs to the field of facility cultivation, and in particular relates to a dragon fruit LED spectrum formula for promoting flowers, increasing production, increasing quality, and its device and application. The pitaya flower-promoting LED spectrum formula of the present invention is: the quantum flux density range of the pitaya canopy is 7-15 μ mol / s / m 2 , the quantum flux density at the bud is in the range of 1‑2μmol / s / m 2 ;The radiation wavelength is in the range of 380nm-780nm, the radiation power of each band accounts for 1%-2% of 380nm-410nm, 20-28% of 411nm-500nm, 20%-28% of 501nm-600nm, 20%-28% of 601nm-700nm 35%‑50%, 701nm‑780nm 6%‑13%. The invention also provides a corresponding device. The spectral formula of the invention effectively promotes the early differentiation of pitaya flower buds, greatly increases the flower bud differentiation rate, and provides the possibility for off-season cultivation of pitaya.

Description

technical field [0001] The invention belongs to the field of facility cultivation, and in particular relates to a dragon fruit LED spectrum formula for promoting flowers, increasing production, increasing quality, and its device and application. Background technique [0002] Pitaya is a CAM plant that only blooms at night. The spectrum required for the transition from vegetative growth to reproductive growth cycle is very specific. As a result, the off-season cultivation of pitaya is limited by the inability to successfully differentiate flower buds, and it has been difficult to break through. In addition, the effect and mechanism of light quality on the quality and taste of dragon fruit are unknown. Contents of the invention [0003] In order to solve the problems in the off-season cultivation of pitaya, a formula of LED spectrum for promoting flowering, yield and quality of pitaya was obtained. [0004] The invention provides a dragon fruit flower-promoting, yield-incre...
