国内外喷灌技术研究现状与发展趋势

Current Situation and Development Trends of Research on Sprinkler Irrigation Technology

综述了近年来有关喷灌技术研究的进展,包括盐碱地喷灌淋洗效果、喷灌对非盐碱地土壤入渗的影响,喷灌对非盐碱地土壤水分分布及其运动的影响,喷灌对作物生长的影响;在此基础上,提出了今后一段时间,我国喷灌技术研究的重点:深入探讨盐碱地喷灌技术参数确定方法,喷灌不同技术参数下的滨海盐碱地土壤水分、盐分分布特征及运移过程,作物根系及地上部分生理生化指标等响应过程,喷灌条件下盐碱地土壤水盐调控方法。

This paper reviewed the recent research progresses in sprinkler irrigation,including leaching effect of sprinkler irrigation in saline land,the effect of sprinkler irrigation on soil infiltration,moisture movement and crop growth in non-saline land.On this basis,it is proposed that the research emphasis during a future period should be focused on the determination method of technical parameters of sprinkler irrigation,the moisture and salt distribution characteristics and the movement rule of costal saline soil,the response process of crop physiological and biochemical indexes under sprinkler irrigation.
