摘　　要：综述了近10年来不同棉区、不同基因型品种、不同种植模式、不同产量水平棉花的养分需求规律,对不同棉区棉花氮磷钾施肥阈值及运筹技术进行了总结;并概述了棉花氮磷钾养分高效利用的机理研究进展,提出了未来棉花施肥技术与营养机理的研究方向。In this paper we reviewed the nutrient requirement characteristics of cotton with different varieties, different planting patterns, and different yield levels in different cotton areas in the recent ten years, and summarized optimum application rates and techniques of fertilization of nitrogen, phosphorus, and potassium fertilizer for cotton in different cotton areas. We also outlined research progress on the high-efficiency utilization mechanisms of nitrogen, phosphorus and potassium for cotton, and put forward research directions of techniques of fertilization and nutrition mechanism for cotton in the future.
