研究明确了太行山地区自然降水与旱作农田土壤水分时空变异特征。农田水量平衡分析表明，生长季土壤储水呈现盈余，甘薯和谷子田分别盈余３０．６８ｍｍ和１２．７９ｍｍ，水分利用效率分别达２７．７２ｋｇ／（ｍｍ·ｈｍ２）和１１．３２ｋｇ／（ｍｍ·ｈｍ２），团棵～茎叶衰退薯块膨大甘薯关键需水期和拔节～抽穗开花～灌浆谷子关键需水阶段耗水分别占全生育期耗水的５４．１％和５０．７％。农田水肥耦合效应显著，依水高效施肥是充分提高该区作物产量和投肥效益的有效措施。
The study identified the temporal and spatial variability of soil moisture in natural precipitation and dry land farming in the Taihang Mountains. The analysis of farmland water balance showed that the water storage in the growing season showed a surplus. The sweet potato and millet field had a surplus of 30.68mm and 12.79mm respectively, and the water use efficiency reached 27.72kg / (mm · hm2) and 11.32kg / (mm · hm2), decay of stems and leaves of tuberose and tubers (tubers and tubers), and the key water consumption stages of key stage of watering-jointing and flowering-filling and filling were 54.1% and 50.7% of the whole growing period respectively. Coupling effect of water and fertilizer in farmland is remarkable. High-efficiency fertilization by water is an effective measure to improve crop yield and fertilizer efficiency in this area.
