Embodiment 1

[0020] Take supplementary light for cucumber cultivation in greenhouse as an example:

[0021] A comparative test of different supplementary light systems was carried out. Test time: October-December 2013; test location: east compartment of the experimental greenhouse of Jiangsu University; test species: Dai Duoxing. Experimental design: high-pressure sodium lamps are used to supplement light. The traditional method of supplementing light requires 8 high-pressure sodium lamps. The method of supplementing light provided by the present invention requires 2 high-pressure sodium lamps. It moves at a speed of 0.1 m / s under the traction of a motor. The interval is 4 minutes. And compared with the traditional light supplement method. Measurement items: single plant yield and total energy consumption. Both the supplementary light method of the present invention and the traditional supplementary light method adopt that when the radiation value in the greenhouse is lower than 3000 lu...

Embodiment 2

[0023] Take greenhouse tomato cultivation as an example:

[0024] A comparative test of different supplementary light systems was carried out. Test time: October-December 2013; test location: west compartment of the experimental greenhouse of Jiangsu University; test species: TRUST FI. Experimental design: high-pressure sodium lamps are used to supplement light. The traditional method of supplementing light requires a total of 8 high-pressure sodium lamps. The method of supplementing light provided by the present invention requires 2 high-pressure sodium lamps. It moves at a speed of 0.4 m / s under the traction of a motor. The interval is 1 minute. And compared with the traditional light supplement method. Measurement items: single plant yield and total energy consumption. Both the supplementary light method of the present invention and the traditional supplementary light method adopt that when the radiation value in the greenhouse is lower than 4000 lux, the supplementa...

Abstract

The invention discloses a mobile light supplementing method. By constructing a ropeway and a moving motor on the roof of a greenhouse and putting light supplementing lamps on the ropeway, the light supplementing lamps can move to and fro; a day is divided into two periods of time, i.e. a period A of time and a period B of time, the period A of time is from 8:00 to 16:00, and the period B of time is from 16:00 to 8:00 in the next day; light is not supplemented in the period B of time, the light supplementing lamps start to supplement light in the period A of time when irradiation in the greenhouse is lower than a set value, at the moment, the motor is switched on, and the light supplementing lamps are dragged by the motor to move to and fro at the speed of 0.1m / s to 0.4m / s on the ropeway to supplement light to greenhouse crops; the time interval of supplementing light to the greenhouse crops is one to four minutes. The principle of the mobile light supplementing method is that light is supplemented by utilizing the different demands of the crops on light in the photosynthetic process, i.e., light is supplemented at the stage of light reaction, and is not supplemented at the stage of dark reaction. The mobile light supplementing method can increase the utilization efficiency of the individual lamps in light supplementing and reduce the energy consumption of light supplementing, the investment of light supplementing equipment and the operation cost of greenhouses, and can be applied to supplement light to greenhouse crops.

Description

technical field [0001] The invention belongs to the field of protected horticultural cultivation, and in particular relates to the technology of supplementing light for greenhouse crops. Background technique [0002] At present, my country has become a major producer of facility agriculture, ranking first in the world in terms of area and output. However, the illumination in the greenhouse is dominated by natural light and the utilization rate is low. Illumination is closely related to the growth of greenhouse crops. To maximize the capture of light energy and give full play to the photosynthetic potential of plants will be directly related to the benefits of agricultural production. In recent years, greenhouse production generally adopts off-season production. Due to the weak light in winter and spring, the crops grow slowly and the yield is low, so it is urgent to supplement light. [0003] The current supplementary light measure is usually to install a supplementary lig...
