基于实时控制灌溉系统的温室黄瓜土壤水分传感器合理埋设位置研究

Research of Soil Moisture Sensor Location Based on the Real-time Control of Irrigation Systems on Greenhouse Cucumber

为研究实时控制灌溉系统中温室黄瓜的土壤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,采用相同的水分上下限,根据水分传感器测定的土壤含水率指导控制灌溉,分析了不同处理黄瓜的生长指标、光合指标、灌水指标、产量及品质指标,系统研究了土壤水分传感器合理埋设位置。结果表明,传感器埋设位置为距滴头水平距离10cm,距滴头垂直深度10cm时较合适。

In order to research the soil moisture sensor reasonable embedding position of real-time control irrigation system of greenhouse cucumber, the six positions of sensors buried in each handling were set through combining with the sensor from the head of horizontal distance and distance drops head vertical distance. According to the determination of moisture sensor guidance control irrigation, the cucumber growth indexes, photosynthetic indexes, irrigation indexes, yield and quality indicators were analyzed un- der different treatments, and the reasonable position laying of soil moisture sensor probe in cucumbers grown were studied systemically. The results showed that the horizontal distance of 10 cm from the water dropper, vertical buried depth of 10 cm from the water dropper were more suitable.
