The invention provides a tomato
plant monitoring method and
system. The tomato
plant monitoring method comprises the following steps: acquiring image data and growth environment data of a tomato
plant to be monitored; determining the growth period of the tomato plant to be detected according to the whole plant image, and determining the saturation
vapor pressure difference of the environment according to the growth environment data; determining the target
irrigation amount of the tomato plants based on the growth period, the saturation
vapor pressure difference and the
irrigation amount application rule; according to the leaf features and the spectral information, identifying the
nutritional status,
disease and pest species and
disease and pest severity of the to-be-monitored tomato plant; determining a target
nutrient solution application scheme based on the
nutrient condition and the
nutrient solution application rule; determining a target
pesticide application scheme based on the
disease and pest species, the disease and pest severity, the growth period and the
pesticide application rule; and controlling the water-
fertilizer-
pesticide all-in-one
machine to perform water-
fertilizer-pesticide preparation and application according to the target
irrigation amount, the target
nutrient solution application scheme and the target
pesticide application scheme. According to the method, tomato plants can be monitored in real time, water,
fertilizer and pesticide are supplied, and the yield and quality are improved.
