| 摘 要： | 针对南疆绿洲灌区224团果树滴灌条件下次生盐渍化的问题,通过在项目区布设观测井,逐月不间断的对地下水的埋深、水位及矿化度进行监测,开展对其变化规律的研究。年度观测结果显示,地下水埋深及水位在果树生育期的灌前及灌后相对较低,灌溉期内最大涨幅接近1m;地下水矿化度灌前、灌后最小,灌溉期内在2～5.8g/L范围内变动,矿化度...

Temporal and Spatial Variation of Groundwater under Drip Irrigation without Drainage System on the Oasis Irrigation Region in south Xinjiang |

| Abstract: | Aimed at the secondary salinization under the condition of drip irrigation on fruiter in Oasis Irrigation Region of South Xinjiang,the groundwater depth,level and mineralization were observed in succession every month in 2010 by monitoring wells.The observed data showed that the groundwater depth,level and mineralization were higher in the growth period irrigation than before or after the irrigation.The most variation of groundwater depth and level was closed to 1 m,the groundwater mineralization was changed from 2 g/L to 5.8 g/L,its highest value appeared after spring irrigation.The results showed that drip irrigation can arise the groundwater level.So drip irrigation without drainage system will be a latent threaten to fruiter growth when the groundwater level is higher.At the same time,the role of drip irrigation washing salt is obvious.The soil salt can be moved and accumulated with the flowage of groundwater to downstream. |
