Abstract
Water storage pit irrigation was combined with drip irrigation, and the influence of discharge of the dripper on soil water and heat movements was examined to explore a better water-saving irrigation. The results showed that the maximum soil moisture content appeared below the drop point after irrigation. In addition, the soil moisture content near the drop point has a greater change than soil moisture content near the wetting front. There was only a little trend after 24 h of irrigation because of water evaporation. It was also found that increased discharge of the dripper not only increased the volume of the wetted soil, but also increased the soil moisture content of each layer. In addition, a different dripper discharge pit has an effect on soil temperature about water storage pit; the temperature is higher with greater flow than with a small flow.
