摘要
灌溉水资源的短缺已成为我国干旱半干旱地区农业持续发展的一个重要限制因素,微咸水资源的开发利用可有效地缓解灌溉水源短缺的问题。总结了国内咸水灌溉对作物生长与产量影响的研究进展,为合理利用咸水资源进行灌溉提供指导。从咸水资源灌溉利用现状来看,膜下滴灌为干旱半干旱地区有效利用微咸水资源以及盐碱地的开发利用提供了有效的手段。但利用膜下滴灌方式进行微咸水灌溉,目前仍存在一些问题,需要进一步研究。此外,如何从流域或区域尺度上评价微咸水灌溉对生态环境的影响,并从更大尺度维持盐分平衡及环境的可持续发展值得深入研究。
The shortage of water resources in irrigation has become an important restraint factor in arid and semi-arid areas in China. The utilization of saline water is an effective way of easing up the shortage of water resources. Drip irrigation under mulch film is an effective way for utilization of saline water and salinized land in arid and semiarid areas. But researches on irrigation with saline water by way of drip irrigation under mulch film are less frequent. It is necessary to go on with the researches. In addition, for sustainable agricultural production, just like water balance, a salinity balance has also to be maintained at the irrigation system basin.
