| 摘 要： | 采用水管理软件DRAINMOD,以SEW30为指标,确定塑料大棚暗管控制排水系统的间距和埋深。然后根据淋洗土壤盐分的需要,选取不同降雨水平年,采用不同的暗管控制排水出口深度及不同的灌水量,共组合成9种方案,以SEW30、土壤0~60 cm土层盐分脱减率、排水量作为评价指标,分析出研究区不同降雨水平年的水管理方案：丰水年... |

| Abstract: | The water management model DRAINMOD is used to design the controlled drainage system according to the standard SEW30 in greenhouse.And then,for typical hydrological year with rainfall frequency of 15%,50% and P=85%,DRAINMOD is used to simulate the groundwater,salt content,SEW30,drainage discharge under 9 water management scenarios that were resulted from different outlet depth of the controlled drainage combined with different additional irrigation water for leaching requirement.The results show that in the... |
