Abstract: The study of plant potassium nutrient is divided into three stages. Five aspect researches, e.g. the physiological function of potassium, the effect of potassium on the yield and quality of agricultural products, adverse circumstance force and potassium nutrient, bio-potassium fertilizer and the choosing of genes which produce low content potassium are reviewed in detail. The study proceeding of potassium in our country in recently years is also discussed. Meanwhile the study way and focal point about potassium have been put forward. Studying and making bio-potassium fertilizer and choosing the genes which produce low content potassium is to be the stress and the effective way to solve the short potassium resource in our country in the future.
