近年来国家对农业种植生产活动给予了诸多优惠政策,激发了农民参与农田种植生产的积极性。水资源供应是农田作物生长的核心条件,维持水分持续供应是保障农作物成活率的关键要素。受到自然环境的营销,农田土壤中水分常出现异常蒸发现象,大大降低了土壤里水分的含有量,对农作物生长造成了不利因素。文章分析了潜水蒸发对农业种植活动带来的不利影响,提出控制潜水蒸发现象的具体对策。
近年來國傢對農業種植生產活動給予瞭諸多優惠政策,激髮瞭農民參與農田種植生產的積極性。水資源供應是農田作物生長的覈心條件,維持水分持續供應是保障農作物成活率的關鍵要素。受到自然環境的營銷,農田土壤中水分常齣現異常蒸髮現象,大大降低瞭土壤裏水分的含有量,對農作物生長造成瞭不利因素。文章分析瞭潛水蒸髮對農業種植活動帶來的不利影響,提齣控製潛水蒸髮現象的具體對策。

In recent years,many preferential policies have given to agricultural production activities by the state ,stimulating farmer ’ s enthusiasm for participating in agricultural growth.Water resources are a vital condition for crop growth and it is a key factor to maintain farmland moisture so as to guarantee the survival rate of crops.Influenced by natural environment , soil water in the farmland often appears abnormal evaporation ,greatly decreasing water content in the soil and leading to unfavorable impact on crop growth.The unfavorable impact of phreatic evaporation on agricultural production is analyzed and concrete countermeasures are put forward in the paper .
