根据多年的田间试验，提出了农田水分条件与水分亏缺对产量影响效应的定量评价方法，并对渭北旱塬农田进行了评价。结果表明：渭北西部旱塬农田水分条件较好；而渭北东部旱塬农田水分条件较差，农田具有较大的灌溉增产潜力；水资源的分配利用和发展灌区应首先考虑渭北东部早塬。 According to years of field experiments, a quantitative evaluation method of the effect of farmland moisture condition and water deficit on yield was proposed, and farmland in Weibei dry land was evaluated. The results showed that: the dry farmland in western Weibei had better water conditions; while the dry farmland in eastern Weibei had worse water conditions, and farmland had greater yield potential for irrigation. The distribution and utilization of water resources should first consider the early Highland.
