Embodiment approach 1

[0068] This embodiment relates to an illumination cultivation method for controlling flowering of chrysanthemums and an illumination device using yellow LEDs for this purpose.

[0069] (chrysanthemum lighting installation)

[0070] figure 1 A method for evaluating the flowering response characteristics of chrysanthemums to nighttime lighting of different wavelengths. At the position of 170 cm on the cultivation vessel 50 after the autumn chrysanthemum "Shenma" 60 was planted, the lighting device 100 equipped with a yellow LED as a semiconductor light-emitting device was installed, and the irradiance and pulse lighting conditions of the lighting device 100 were investigated. influences.

[0071] Figure 4 It is a spectral distribution diagram of an AlGaInP-based yellow LED used in this lighting device and a lighting device of a yellow fluorescent lamp for comparison. Hereinafter, in the present embodiment, the AlGaInP-based yellow LED is simply referred to as a yellow LED. ...

Embodiment approach 2

[0090] The present embodiment relates to a cultivation method in which a field is divided into several areas and illuminated at night under different irradiation conditions for each area, and a lighting device used therefor. Chrysanthemum is a short-day plant, and it will not bloom if the length of daylight does not shorten. Taking advantage of this property, electronic irradiation cultivation in which the flowering date is controlled according to the listing date of chrysanthemum is carried out. In this embodiment, yellow LEDs are used for night lighting of the electronic irradiation cultivation, and lighting having both effects of flowering control and insect repelling effect on moths is provided, and flicker control can be easily performed focusing on LEDs.

[0091] Next, an example of electron irradiation cultivation will be described. After the chrysanthemums were planted, night lighting was carried out for a prescribed period, and the lighting was stopped when the heigh...

Embodiment approach 3

[0104] In this embodiment, the waveform of the light emission pulse is further pulse-width-modulated within the width of the bright period.

[0105] In terms of the waveform of the light-emitting pulse in this embodiment, as Figure 14 As shown, the bright period width in one bright and dark cycle is 20ms, during which, for example, the light-on period within the bright period width of 1ms and the light-off period within the bright period width of 1ms are alternately repeated 10 times, that is, the duty cycle within the bright period width The factor is set to 50%. In addition, the so-called duty factor within the bright period width refers to the lighting period within the specified period width / (the lighting period within the bright period width+the light-off period within the bright period width).

[0106] From this, it is difficult for noctuid adults to recognize the light-on period and the light-off period within the bright period width as flickering in the bright period...

Abstract

Disclosed is a cultivation method for illuminating plants at night or in a lightless environment. For the illumination, the exit light has an emission peak wavelength in the green to red region and flashes with a flashing pattern of prescribed light period duration and dark period duration. For the flashing, the duty cycle given by formula (1) is 50% or less. Duty (%) = period duration / (light period duration + dark period duration) x 100            (1) Provided is a cultivation method that controls the blooming of short-day plants such as chrysanthemums while providing insect-screening effects such as mothproofing.

Description

technical field [0001] The present invention relates to a plant lighting cultivation method (product production method) with the effect of repelling pests and a lighting device for plant cultivation. Background technique [0002] Since noctuid moths such as ear moth and Spodoptera litura that harm flowers and trees have acquired resistance to insecticides, it is very difficult to control them with insecticides. In the genus Caryophyllum and Rosa, nighttime lighting is being used as a control method instead of drugs, and yellow fluorescent lamps for moth control, which have a high moth control effect, are used for adults that fly to the nursery to lay eggs. [0003] In addition, there is also a yellow LED insect-proof lamp system, which is equipped with a yellow light-emitting diode (hereinafter referred to as a yellow LED) instead of a yellow fluorescent lamp, and improves the pest repelling effect by making the yellow LED blink (Japanese Patent Laid-Open No. 2003-284482 (Pa...
