摘要
在温室土壤-作物-环境的连续体中,作物水分损耗、吸收和水分利用效率一直是研究的热点,温室作物水分来源的唯一途径是灌溉。为了在生产实践中指导节水灌溉,从近些年来节水灌溉的新技术新方法——滴灌和调亏灌溉入手,主要综述了温室内作物调亏灌溉的研究,包括调亏灌溉的节水及增产机理,调亏灌溉相应的灌溉指标,影响调亏灌溉的环境因素,以及作物本身不同时期对水分亏缺的反应。
For the soil-plant-environment continuum systems inside greenhouse, researches always focused on water loss and absorb and crop water use efficiency. Irrigation was the only water source for greenhouse crops. This paper started from the new technologies and methods of water-saving irrigation of recent years-drip irrigation and regulated deficit irrigation, and summarized the research of regulated deficit irrigation of greenhouse. It composed the production mechanism, the adaptive irrigation index of regulated deficit irrigation, the environmental factors work on regulated deficit irrigation, especially, the crop＇ s reflection to the waterdeficit during the different growth period.
