Embodiment approach 1

[0091] (concept of lighting cultivation)

[0092] figure 1 It is a conceptual diagram of the lighting cultivation in Embodiment 1 of this invention.

[0093] refer to figure 1, For example, plants such as chrysanthemum 60 (Qiu chrysanthemum) are colonized in fields (plant cultivation areas). Chrysanthemum 60 contains growing point 61 . A lighting device is provided on the field, and the lighting device is equipped with a plurality of LED light sources 100 . These LED light sources are pulsed on at night. The illumination area 110 is illuminated by pulsed lighting of the LED light source 100 . In the illumination area 110 , the adults 130 of the Noctuidae family visually recognize the light, thereby suppressing the behavior of the adults of the Noctuidae family 130 . As a result, the flying of the Noctuidae adults 130 to the field for laying eggs or mating is suppressed, and the egg laying and mating actions of the Noctuidae adults 130 are suppressed. As a result, the da...

no. 2 Embodiment approach

[0141] In Embodiment 1, it was shown that the pulse lighting of LED can prevent the flowering delay of a chrysanthemum while having an anti-moth effect. On the other hand, in the case of monotonous pulse lighting, the action inhibition of Noctuididae was also sometimes weakened due to the adaptation of pulse lighting. In this embodiment, this point will be described first.

[0142] (data showing adaptation of noctuid)

[0143] 16 male cotton bollworms were tested using a yellow fluorescent LED light source. Figure 10 Actigraphy shown, with irradiance set to 50mW / m 2 , Lighting at night under the pulse conditions of 20 ms in bright period and 80 ms in dark period to investigate the number of sensor occlusions accompanying flight. exist Figure 14 The results are shown in . Figure 14 It is a graph showing the change of flight activity in the dark period according to different ages. The vertical axis is the number of sensor occlusions, and D1 to D5 on the horizontal axis a...

Embodiment approach 3

[0170] In Embodiment 3, the growth status of the cultivated chrysanthemum and the state of damage by noctuid moths were investigated in the "no-treatment zone", "asynchronous lighting zone" and "synchronous lighting zone". The following shows the results of an experiment in which the growth status of chrysanthemums was observed when "plurality of asynchronous light sources" and "synchronous light sources" were used.

[0171] (Experiment 1: Comparison of no treatment area and non-synchronized lighting area)

[0172] In this experiment, the yellow chrysanthemum "Jingzhiqi" was cultivated in the non-treatment area and the asynchronous lighting area, and the cultivation status of each chrysanthemum and the damage status caused by the noctuid moth were compared. In the no-treatment area and the non-synchronized lighting area, fungicides were used according to farm practices and insecticides that had less impact on Noctuidae were used, but acaricides that had no impact on Noctuidae ...

Abstract

The disclosed plant cultivation method and lighting device can repel insects while also controlling the flowering reaction or avoiding delaying the flowering of short-day plants such as chrysanthemums. Said method uses illumination from a plurality of light sources, each of which emits light having a peak wavelength in the red-to-green region. Each light source goes through a synchronized or independent flashing pattern in which the emission intensity changes cyclically, each cycle consisting of a bright period with a prescribed width and a dark period with a prescribed width, the dark period having a lower time-average brightness than the light period. The duty cycle of the flashing pattern, as defined by formula (1), is at most 50%. (1) Duty cycle = width of bright period / (width of bright period + width of dark period) 100% In at least part of the region illuminated by a plurality of light sources, the combination of the illumination patterns from said plurality of light sources produces an insect-repelling effect.

Description

technical field [0001] The invention relates to a lighting cultivation method for plants, a lighting device for preventing insects and a lighting system for preventing insects. Background technique [0002] Since Noctuidae such as cotton bollworm and Spodoptera litura that eat flowers and trees have acquired resistance to a variety of insecticides, it is very difficult to control them with insecticides. For carnations and roses, instead of using insecticides, adult insects that fly to the field to lay eggs are illuminated at night using yellow fluorescent lamps for moth control, which have a high moth control effect. [0003] Regarding the nighttime lighting produced by such moth-proof yellow fluorescent lamps, for example, Japanese Patent Application Laid-Open No. 2003-274839 (Patent Document 1) discloses a yellow LED insect-proof lamp equipped with yellow light-emitting diodes (hereinafter referred to as yellow LEDs) instead of yellow fluorescent lamps. system. Also, for...
