Abstract: 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.
