辽宁地区潜水蒸发规律研究

Experiment Research on Phreatic Evaporation Rules in Liaoning Province

根据辽宁台安试验站历年潜水蒸发试验资料,分析了作物生育期、埋深、土质、大气蒸发能力、降雨等影响潜水蒸发的因素,并用回归分析方法建立了逐月潜水蒸发模型,为辽宁地区计算有作物生长条件下的潜水蒸发量提供了潜水蒸发计算公式。

Based on the experiment data of phreatic evaporation in Taian experimental station in Liaoning Province, factors influencing phreatic evaporation, such as crop growth period, phreatic depth, soil texture, atmosphere evaporation capacity and rainfall, are analysed, and the empirical formulas of monthly phreatic evaporation has been established for calculation of phreastic evaporation with crop growth in the middle area of Liaoning Province.
