Abstract: Irrigation is an important link in greenhouse production but unreasonable irrigation control methods will cause waste of water resources. In this paper, the development and application of irrigation control strategies in greenhouse were reviewed, and the research progress of irrigation control strategies in greenhouse production was described from three aspects: transpiration model, soil/substrate moisture sensor, and crop characteristics. The advantages, disadvantages and applicable conditions of different transpiration models used to formulate irrigation control strategies were analyzed and compared, and the measurement principles of common humidity sensors were analyzed and discussed. Irrigation control strategy based on crop characteristics was classified and discussed from the point of view of morphology and physiology. Finally, the current greenhouse irrigation control strategy was summarized and prospected from the integration degree of control strategy, matching degree, generalization and universality of irrigation control strategy and irrigation control equipment. From the analysis, it was found that soil moisture sensor and plant information sensor had great development prospects. In future, the development of irrigation control strategy and irrigation control equipment will continue to interact and integrate, and the development trend of greenhouse watersaving irrigation control technology will be more efficient, simpler, and more intelligent.
