菠萝灌溉施肥技术研究进展

季节性干旱是限制菠萝增产提质增效的重要原因,发展“以水促肥,以肥促产,水肥高效耦合”的现代灌溉施肥技术,是应对季节性干旱,促进菠萝增产提质增效的重要途径。本文从华南地区季节性干旱时空分布特征、干旱胁迫对菠萝生长发育的影响、我国菠萝水肥管理现状、灌溉施肥技术对菠萝生长发育的影响等4个方面简要阐述了我国菠萝灌溉施肥技术发展的必要性,重点从现代灌溉施肥方式、耗水规律和养分吸收规律等3方面总结了菠萝灌溉施肥技术研究进展,并结合研究进展提出我国菠萝灌溉施肥技术目前存在的问题,探讨未来可能的研究重点和发展方向,为菠萝灌溉施肥技术的研究与应用提供参考。

Research Progress on Fertigation Technology of Pineapple

Seasonal drought is an important reason to limite the yield, quality & water and fertilizer use efficiency of pineapple. Developing fertigation technology of water promotes fertilizer, fertilizer promotes production, water and fertilizer combine efficiently is an important way to cope with seasonal drought and promote the yield, quality & water and fertilizer use efficiency of pineapple. In this paper, the necessity of the development of pineapple fertigation in China was briefly expounded from four aspects, including the temporal-spatial characteristics of seasonal drought in south China, the effects of drought stress on the growth and development of pineapple, the current situation of pineapple water and fertilizer management in China, and the effects of fertigation technology on the growth and development of Pineapple. The advances in fertigation technology of pineapple was summarized mainly from three aspects: modern irrigation and fertilization methods, water consumption regularities and nutrient absorption regularities. Finally, combined with the research progress put forward the existing problems of pineapple fertigation technology in China, and the possible research focus and development direction in the future were discussed. The purpose of this paper is to provide references for the research and application of pineapple fertigation technology.
