甘薯是典型的喜钾作物，钾对甘薯产量和品质具有重要影响。不同的氮钾配比及不同的施钾时期对于甘薯的生理生化过程、形态和产量的形成产生不同的影响。本文对甘薯栽培中氮素和钾素的利用现状、吸收的生理机制及养分调控等进行回顾，围绕钾素后移和氮钾交互两个关键问题进行论述，分别概述了钾素和氮素对甘薯生长及产量形成的影响、氮钾交互作用对甘薯生长调控作用，强调了分期施钾和氮钾配比在甘薯栽培中的必要性。从不同的氮钾配比和施钾方式两个方面进行甘薯生长的调控研究，可以为甘薯产量和资源利用效率的提高提供理论和实践指导。

Sweet potato is a typical potassium crops.Potassium has an important effect on grain yield and quality of sweet potato.In this paper,the current situation of exploitation of nutrient elements in the course of cultivation of sweet potato,nutrient absorption physiological mechanism and regulation are re-viewed.This paper discussed two key including postponing potassium and N,K interaction.An overview of the effects of potassium,respectively,and nitrogen on the growth and yield formation of sweet potato, sweet potato growing interaction between nitrogen and potassium regulatory role,emphasizing the necessi-ty of staging the ratio of potassium and nitrogen and potassium in the potato cultivation.And the advices about further development were brought up.It can provide theoretical and practical guidance for potato production and resource use efficiency.
