摘要
膜下滴灌水肥一体化技术是先进的灌水施肥技术和栽培技术的集成。它是一种高效能利用作物水肥的技术,是眼下农业工程领域研究的焦点之一。首先阐述了目前国内农业水肥利用效率低下的现状,然后简要回顾了滴灌水肥一体化技术发展过程,阐述了膜下滴灌水肥一体化栽培马铃薯的需水需肥规律、水肥耦合机制、土壤水盐运移规律研究进展,分析了膜下滴灌技术目前存在的主要问题,提出了相应的解决对策并展望了今后需要进一步研究和探索的方向,以期为水肥一体化在马铃薯栽培中的应用提供参考。
Water and fertilizer integration under mulch drip irrigation was advanced irrigation and fertilization techniques and cultivation techniques integration. It＇s an efficient water-saving and fertilizer-saving technology,which was one of the hot spots in current research field. Current status of low domestic agricultural fertilizer use efficiency was firstly elaborated,and then development of fertigation under drip irrigation was briefly reviewed. Water and fertilizer requirement rule under drip irrigation,soil water and salt migration rule were summarized. Main problems existing in technology of drip irrigation under film were analyzed,corresponding countermeasures and prospects for future research and exploration needs further direction were put forward,with a view to water and fertilizer integration in application of potato cultivation reference.
