Abstract

The invention provides a light supplement method, device and system for three-dimensional greenhouse seedling-raising. The method comprises the steps of: obtaining the illumination intensity and distribution of each layer of a three-dimensional greenhouse seedling-raising frame in a current place respectively; according to the preset illumination demands of greenhouse crops to be subjected to light supplement on each layer of the three-dimensional greenhouse seedling-raising frame and the illumination intensity and distribution of each layer of the three-dimensional greenhouse seedling-raising frame, calculating the light supplement intensity required by each layer of the three-dimensional greenhouse seedling-raising frame respectively; and according to the light supplement intensity required by each layer of the three-dimensional greenhouse seedling-raising frame, controlling light supplement lamps to perform light supplement. According to the method, natural illumination can be utilized to the maximum extent while the three-dimensional greenhouse space is fully utilized, the number of light supplement lamps and the energy consumption for light supplement during three-dimensional seedling-raising are reduced, and the seedling quality and the growth speed of each seedling-raising layer can be ensured to be consistent; the method has the advantages that the energy consumption is reduced and the lamp hardware input and the operation costs during the three-dimensional greenhouse seedling-raising are reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouse facilities, in particular to a method, device and system for supplementing light for three-dimensional growing seedlings in a greenhouse. Background technique [0002] In recent years, my country has become a large country of facility agriculture. In order to save land and increase production, greenhouse vertical seedlings have also developed rapidly in my country. However, the natural light intensity received by each layer of the vertical seedling rack in the greenhouse is different and insufficient. If you simply use the same light supplement for each layer, it will cause uneven growth of seedlings on each layer and affect product quality. [0003] The natural light received by each layer of the three-dimensional sports seedling rack in the greenhouse changes from strong to weak from top to bottom. Except for the top layer, the natural light intensity of other layers cannot meet ...
