摘　　要：将由计算机视觉识别得到的作物缺素信息应用到作物营养液调控及供给中,将作物的缺素信息与智能调控器储存的作物生长的专家信息相结合,判断作物所需的肥液量,给出合适的控制命令,调整营养液调控系统参数,对营养液的调控系统进行控制,从而提高了营养液灌溉的准确度,取得了较好的结果。Nutrient deficiency information obtained by using computer vision technology is applied into control and regulation system of nutrient solution for crop planted in greenhouse. The nutrient deficiency extent and expert advised nutrient values are combined and compared. InteUigent controller regulate and control parameters of irrigation system including pump operation time and valve opening angle to determine components of nutrient solution and supplying quantity to meet crop development. The research indicates that the proposed method improves the accuracy of nutrient solution and reaches good result.
