摘  要：
设置基于光辐射、基质含水量+回液电导率和时序灌溉决策3个处理,通过监测番茄株高、茎粗、产量、品质和基质含水量等指标,探索高品质番茄基质栽培灌溉决策。结果表明:基于光辐射和基质含水量+回液电导率灌溉决策的番茄长势和产量均优于时序灌溉决策,果实糖酸比分别比时序灌溉决策提高了60.8%和54.3%,番茄红素含量分别提高了14.9%和18.6%,灌溉液生产效率分别提高了39.6%和49.6%。集成的高品质番茄自动灌溉决策,为实现智能水肥管理提供了模型支撑。

摘  要：
This study designed 3 treatments including optical radiation,matrix moisture content + return EC sensor,and time sequence irrigation decision,to investigate irrigation decision for substrate cultivation of high quality tomato,through monitoring tomato plant height,stem diameter,yield,quality and matrix moisture content.The results showed that tomato growth vigor and yield based on optical radiation and matrix moisture content + return EC sensor irrigation decision were superior to that by time sequence method.The fruit sugar acid ratio was raised by 60.8% and 54.3%,respectively;lycopene contents were increased by 14.9% and 18.6%,respectively;irrigation fluid production efficiency were increased by 39.6% and 49.6%,respectively. Thus,the compositive and automatic irrigation decision for high quality tomato has provided model support for realization of intelligent water/fertilizer management.
