Zusammenfassung: | To provide an irrigation system capable of executing irrigation with less adverse effect to growth of plants, and a controller.SOLUTION: A treatment part determines whether or not irrigation should be executed by using the temperature of feedwater which is present in a feedwater route to which irrigation is supplied and the soil temperature of a farm field. A signal output part, in the case where the treatment part determines that the soil temperature rose above the water temperature and the water temperature dropped from a first threshold value, outputs a signal for prohibiting irrigation. A signal output part, in the case where the treatment part determines that the soil temperature did not rise above the water temperature, outputs a signal for prohibiting irrigation. A signal output part, in the case where the treatment part determines that the soil temperature did not rise above the water temperature, or the soil temperature rose above the water temperature and the water temperature rose above the first threshold value, outputs a signal for executing irrigation.SELECTED DRAWING: Figure 8
【課題】植物の生育に対する悪影響を抑えた潅水を実施可能な潅水システムおよび制御装置を提供する。【解決手段】処理部は、潅水が供給されている給水経路に存在する給水の水温と圃場の地温とを用いて潅水を実施するか否かを決定する。信号出力部は、処理部によって地温が水温を上回りかつ水温が第1閾値を下回ると判定された場合に潅水を禁止する信号を出力する。信号出力部は、処理部によって地温が水温を上回っていないと判定された場合に潅水を禁止する信号を出力する。信号出力部は、処理部によって地温が水温を上回っていない場合、または地温が水温を上回りかつ水温が第1閾値を上回ると判定された場合に潅水を実施する信号を出力する。【選択図】図8 |
