摘要: 灌溉是温室生产中的一个重要环节,不合理的灌溉控制方法会造成水资源的浪费。通过对温室灌溉控制策略的发展和应用情况进行综述,从基于蒸腾模型、土壤/基质湿度传感器、作物特性3个方面阐述当前温室生产中灌溉控制策略的研究进展。针对用于制定灌溉控制策略的不同蒸腾模型分析对比各自优缺点和适用条件;针对常见湿度传感器,分析其测量原理并讨论具体应用;从形态学和生理两个角度对基于作物特性的灌溉控制测量进行分类讨论。最后,对当前温室灌溉控制策略从控制策略融合度、灌溉控制策略与灌溉控制装备匹配度和泛化性以及普适性方面进行总结和展望,通过分析展望发现土壤水分传感器和植物信息传感器很有发展前景。在未来的发展中,灌溉控制策略与灌溉控制装备的发展将会不断交互融合,温室节水灌溉控制技术的发展趋势必定向着更高效、更简便以及更智能化的方向发展。

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.

Key words: greenhouse irrigation, control strategy, evapotranspiration model, soil moisture sensor, crop characteristics
