摘要
通过查阅大量文献和检索有关资料 ,综述了基于时间、空间土壤水分调控的果园时空亏缺调控灌溉技术———调亏灌溉(RDI)和根系分区交替灌溉 (APRI) ,阐明了两种灌溉技术的概念、理论依据、节水优产机理和研究进展 ,提出了考虑果树生育期和根区供水模式交互作用的时空综合调控技术 。
With investigation of references and former research data,two new spatio-temporal controlling theories of controlled irrigation in orchard, i.e., regulated deficit irrigation (RDI) and alternate partial rootzone irrigation (APRI)were introduced. The concept, theory system, water-saving mechanism and research status of the two irrigation techniques were discussed, the concept of space-time interacting controlled irrigation was put forward and the application prospects and problems of the two irrigation techniques were also analyzed.
