蓄水坑灌法研究进展

摘要

蓄水坑灌法是一种适用于我国北方干旱半干旱地区果林灌溉的中深层立体灌溉方法.通过系统地整理和总结蓄水坑灌SPAC系统近十几年的研究成果,分析了蓄水坑灌法的节水保肥增产机制,并指出需要进一步研究的问题,为加快蓄水坑灌理论及技术的推广应用提供理论依据.%Water storage pit irrigation is a new middle-depth tridimensional irrigation method,which is suitable for orchard and arboretum in arid and semi-arid region of China.By searching the relevant literatures and studies in recent years,this paper systematically summarized and analyzed its water-saving,fertilizer conservation and yield improvement mechanisms in orchard SPAC system under water storage pit irrigation,and reviewed the application problems of this new irrigation technique.It can provide a basis for the accelerated generalization and adaptation of irrigation theory and technologies under water storage pit irrigation.
