Embodiment 1

[0024] Example 1 Cultivation test of columbine CCFL light source

[0025] 1. Materials and methods

[0026] Using CCEL as the supplementary light source, three columbine varieties (purchased from Dongsheng Seed Industry Co., Ltd.) of white flowers, pink flowers and blue purples were tested for supplementary light in the greenhouse from February 14 to April 14, 2009. The intensity is 2500lux, the light supplement time is from 18:00 to 08:00 the next day, set the control, repeat three times, randomly discharge the plant materials under the light source, measure the number of leaves, plant height, flowering time and flowering number every 15 days , to calculate the net growth.

[0027] 2. Results and Analysis

[0028] Count the number of leaves, plant height, flowering time and flowering number of columbine columbine, pink columbine columbine, blue purple columbine columbine and their respective contrasts respectively, and the results are shown in table 1 and table 2 respective...

Embodiment 2

[0035] Example 2 CCFL fill light frame

[0036] Such as Figure 4 and 5 Shown, a kind of CCFL supplementary light frame that is used for plant cultivation of the present invention, comprises frame body 1, has a suspension board 2 for hanging CCFL lamp tube at the upper end of frame body 1, hangs below described suspension board several A CCFL lamp 3. The CCFL lamp 3 is connected to a controller, and the controller controls the switch and light intensity of the CCFL lamp 3 .

[0037] In addition, the height of the suspension board is adjustable, and the height of the suspension board on the frame body can be adjusted, or the height of the frame body can be adjusted to realize the adjustment of the height of the suspension board. In addition, the height of each CCFL lamp tube can also be adjusted.

[0038] Because CCFL is a cold light source, it can be very close to the plants without burning them. The height of the fill light shelf is adjustable. The height of each CCFL li...

Abstract

The invention provides application of a CCFL (Cold Cathode Fluorescent Lamp) in plant cultivation, in particular application of the CCFL as a light source in the plant cultivation. According to the invention, the utilization rate of a light source can be further determined to be improved by adopting a specific mixture ratio of red light to blue light and the growth amount of plants can be effectively improved by adopting specific illumination intensity through research. The CCFL used as the light source can be widely used for cultivating the plants, in particular for greenhouse plants and can be used for improving the growth efficiency of the plants and reducing energy consumption. The CCFL is a cold light source, so that the CCFL can be closed to the plants without burning the plants. In addition, the invention further provides a lamp tube type CCFL light supplementing rack. The height of the light supplementing rack can be adjusted. The height of each CCFL can be adjusted according to the heights of the plants. The CCFL light supplementing rack can be used for supplementing light to the plants from the front side or the side.

Description

technical field [0001] The present invention relates to a novel light source for plant growth. Background technique [0002] Greenhouses can create a suitable small environment that is easy to control for plants, and keep plants from being affected by seasons and environments as much as possible. Greenhouse cultivation technology has now been widely used in various fields of plant cultivation. For example, we can still eat fresh vegetables in winter, which is the result of using greenhouses for off-season vegetable cultivation. In addition, greenhouse cultivation techniques can also be used to cultivate plants at different latitudes. For example, most botanical gardens have various ornamental plants cultivated in greenhouses. [0003] For a long time, natural light has been used for the growth of greenhouse plants. However, due to the loss of sunlight due to the structure and materials of the greenhouse, or the short duration of sunlight due to seasonal reasons, artificial ...
