Problems solved by technology

In addition, this method is limited to Solanaceae plants and may not be applicable to other plants
Moreover, this method does not take into account the flower bud differentiation of plants
In addition, it is difficult for workers to visually identify plants, which leads to low work efficiency

Embodiment Construction

[0020] will now refer to Figures 1 to 6 A plant cultivation system according to one embodiment of the present invention will be described. The present plant cultivation system is designed to promote the growth of plants, in particular flowering plants, in facility cultivation such as fully enclosed plant seedling production systems, agricultural vinyl greenhouses or glass greenhouses, or outdoor cultivation.

[0021] Such as figure 1 As shown, the plant cultivation system 10 includes a first light source 1, a second light source 2, a control unit 3 configured to control the first light source 1 and the second light source 2 to perform respective illumination operations, and configured to set the time The time setting unit 4 of the zone, in the time zone, the control unit 3 controls the first light source 1 and the second light source 2 to perform respective illumination operations. The control unit 3 is electrically connected to the first light source 1 , the second light s...

Abstract

In a plant growing system, a first light source irradiates a plant with light having a peak wavelength in a range from 380 to 560 nm and a peak wavelength in a range from 560 to 680 nm and a second light source irradiates the plant with far-red light having a peak wavelength in a range from 685 to 780 nm. Further, a control unit controls the first and the second light source to perform respective irradiation operations and a time setting unit sets a first and a second time zone in which the control unit controls the first and the second light source to perform the respective irradiation operations. The first time zone ranges from a first predetermined time before sunset to a second predetermined time after sunset, and the second time zone starts after the first light source completes its irradiation operation.

Description

technical field [0001] The present disclosure relates to a plant cultivation system for controlling the growth of plants. Background technique [0002] Conventionally, there is known a plant cultivation method in which the growth of plants is controlled by irradiating the plants with light emitted from an artificial light source. As an example, a method is known in which plants are subjected to a short-day treatment (e.g. See Japanese Unexamined Patent Application Publication No. 2009-136155). [0003] As another example, there is known a method in which at least one of red light and far-infrared light is irradiated to Solanaceae plants (specifically, tomato) within 1 to 3 hours after sunset in order to obtain high sugar concentration. Tomato (see, for example, Japanese Unexamined Patent Application Publication No. 2007-282544). [0004] However, the methods disclosed in Japanese Unexamined Patent Application Publication No. 2009-136155 do not necessarily promote the grow...
