| Abstract: | Potassium is one of essential macronutrients required by tea tree. It plays a vital role in growth of tea tree. In this paper, a review on the research progress of potassium in tea tree was made, which included physiological function of potassium in tea tree, potassium deficiency and nutrition diagnosis, effects of potassium fertilizer on the yield and quality of tea, potassium condition in tea-grown soil and application of potassium fertilizer, etc. Some suggestions such as the dynamic equilibrium of potassium pool after the application of potassium fertilizer, effect of potassium and middle or micronutrients combined application and how to apply potassium fertilizer to improve the potassium usage efficiency and maintain potassium balance in soil were put forward for the further study. |
