近几年来,沿海大棚农业种植区迅速发展,农民在进行大棚建设的过程中,不太重视棚前排水沟的建造,以致部分大棚在大雨中被淹,造成严重损失。针对这个问题,省沿海水利科学研究所开展了排水沟标准与布局试验研究。通过正交试验确定了沿海大棚种植区内三沟标准,墒沟间距6m、沟深35cm,腰沟间距40m、沟深60cm,田头沟沟深60cm的组合,满足了试验区大棚排水和降渍要求。通过对大棚农业种植区降雨人渗的观测,定量分析了大棚区与大田地下水位变化规律,揭示了大棚区与大田不 In recent years, the agricultural planting areas in coastal greenhouses have been developing rapidly. During the construction of greenhouses, peasants paid little attention to the construction of drainage ditches in front of the sheds. As a result, some of the greenhouses were flooded in heavy rains, causing serious losses. In response to this problem, the provincial Institute of Coastal Water Resources to carry out the drainage ditch standards and layout of experimental study. Through the orthogonal experiment, the combination of SanGou standard, furrow spacing 6m, furrow depth 35cm, furrow spacing 40m, furrow depth 60cm and furrow depth 60cm in the coastal greenhouses were determined to meet the requirement of drainage and falling Stain requirements. Based on the observation of rainfall infiltration in the agricultural planting area in greenhouse, the variation regularity of groundwater level in greenhouse and field was quantitatively analyzed,
