摘　　要：The study was conducted to study the rational setting position of sand moisture sensor in real-time control irrigation system for greenhouse tomato. Six treatments were designed according to horizontal distance and vertical depth from sensor to dripper, different upper and lower water content limits were set for differ-ent growth stages, and indexes including tomato growth, root, photosynthetic param-eter, quality, WUE and yield were systematical y analyzed. The result showed that it is suitable to bury soil moisture sensor in sand field with a vertical depth and a horizontal distance both of 10 cm from the dripper.为研究实时控制灌溉系统中温室番茄的沙地水分传感器合理埋设位置,将传感器距滴头水平距离与距滴头垂直距离结合后设定6个处理,不同生育期水分传感器设定不同的土壤含水量上下限,系统分析了沙培番茄生长、根系、光合参数、品质、WUE、产量等指标,结果表明:TDR土壤水分传感器埋设在沙地距滴灌带滴头垂直深度、水平距离均为10 cm处时较适宜。
