Abstract The wide application of drip irrigation under mulch in semi-arid agricultural regions China not only improves water efficiency, but also affects formation groundwater and the mechanism infiltration to a certain extent. This paper takes typical region as research object. movement soil three types underlying surface was simulated by Hydrus-2D model for quantitative analysis recharge. influence on depth cumulative amount different level years simulated. Taking normal flow year an...
Abstract Stemflow (SF) is an important source of water for maize ( Zea mays L.) growing in arid areas, and very agricultural management. However, the results previous studies different regions are quite different. There also a lack in‐depth research on SF process at each growth stage. The purpose this study was to analyze effects rainfall characteristics morphology during entire maize‐growing period, quantify stemflow rate (SR) western Liaoning, differences periods, establish multiple...
Water scarcity has been a critical constraint to economic development in semi-arid areas of China, so optimizing irrigation scheduling become essential. This study obtained quantitative relationships between crop yield, water consumption, and quantity based on the Hydrus-2D Stewart models. Different scenarios were evaluated obtain best principle simultaneous conservation productivity improvement with evaluation indicators use efficiency (WUE), (IWUE), Critic-Topsis method. Taking drip under...
Abstract The imbalance between exploitation and recharge the yearly decline in water tables is a common resource problem semi-arid areas China. To ensure sustainable use of groundwater stability regional hydrological cycle, reasonable control table need to be determined achieve balance recharge. Based on characteristics vertical cycle irrigation areas, this paper used combination situ field experiments software simulations calculate infiltration under three types subsurface conditions,...

In the agricultural region of Xiliao River Plain, drip irrigation under mulch has been widely implemented. It not only saves water, but also changes structure underlying surface land, which affects local hydrological cycle to a certain extent, and makes process nitrogen transportation in soil with new characteristics. This study analyzed distribution NH4-N, NO3-N, NO2-N different depths during whole growth period three conditions, including mulch, border irrigation, bare area through field...
