| Abstract: | Based on the data of soil water capacity at the depth of 200 cm from 5 monitoring stations in spring wheat areas in the Loess Plateau of Gansu Province and the theory of circulatory system of atmospheric precipitation-soil water-plant,the impact of soil water capacity and water consumption on the water productivity of spring wheat is studied.The result shows that this region is a good natural soil reservoir,exhibiting good water storage and water-retaining properties.Though soil water capacity in arid,semia... |
