Farmland Hydrology Cycle and Agronomic Measures in Agroforestry for the Efficient Utilization of Water Resources under Karst Desertification Environments

Severe soil-water loss and unfertile soil frequently occur under karst desertification environments. The surface-underground dual structure in these areas allows the surface water to leak into subsurface through cracks sinkholes, as well other conduits, causing a special “karst drought”. Hence, water-resource shortage has become challenge for local agricultural development. To realize efficient utilization of resources, an urgent need is clearly understand study law farmland hydrological cycles agroforestry practices, which still understudied. Here, we focused on cycle at scale water-saving measures three representing different degrees desertification. First, significant positive correlation was found between total available precipitations land evapotranspiration (LET). Second, agronomic measures, content all higher than that control group while evaporation lower. This indicates can contribute use resources by halting increasing content. Third, dwarf dense planting pruning technologies were helpful inhibiting crop transpiration reducing vegetation interception. Fourth, agroforestry, 77.45% precipitation transformed storage, 24.81% evaporation, 20.73% plant transpiration, 17.40% groundwater, 5.18% However, their sum greater 100%, suggesting farmland-scale open system. implication practices bring certain benefits constraining conversion ineffective promoting storage effective water, thus opening up promising opportunities efficiently utilizing areas. finding also desertification, conservation, drought alleviation.
