摘要（英）：The invention discloses a light-supplement sterilization method and device for crops and a data collection device and belongs to the technical field of light-supplement sterilization for crops. The multispectral light-supplement sterilization method for the crops comprises the following steps that a, a light-supplement spectral waveband for the crops is acquired; b, a light-supplement light-intensity range for the crops is acquired; c, a light-supplement band-pass optical filter set is customized; d, light reflection intensity data of light compensation points and light saturation points of the crops is collected; e, the crops are subjected to light-supplement or sterilization judgement and operation. The light reflection intensity data collection device based on the light-supplement spectral waveband for the crops comprises a CCD camera, a light-supplement band-pass optical filter mounting structure for mounting a light-supplement band-pass optical filter and the light-supplement band-pass optical filter. The multispectral light-supplement sterilization device for the crops comprises the light reflection intensity data collection device, a spectral continuous adjustable light source and a control circuit, and the control circuit comprises a single chip microcomputer MCU and one or more starting switches. The light-supplement sterilization method and device for the crops and the data collection device have the advantages that the light-supplement time is short, the light-supplement light intensity range is precise, and the energy is saved.
