Abstract:

Potassium is one of the large amount of elements needed by plants. Potassium plays an important role in plant growth and development. However,there are problems of insufficient and low utilization rate of potassium fertilizer in agricultural production. It analyzed the research papers on potassium nutrition at home and abroad since 1965,and summarized the following five aspects. Firstly,it summarized the general situation of potassium,it summarized the general situation of potassium, distribution problem and lack of potassium resource in our country. Secondly,the nutritional function,stress resistance,yield and quality of potassium were summarized.Thirdly,the concept,principle and implementation method of potassium nutrition diagnosis were introduced,the importance of potassium nutrition diagnosis was emphasized,and the research status of potassium nutrition diagnosis in recent years was analyzed and summarized.Fourthly,the position of potassium absorption,the factors affecting potassium absorption and the ways and methods of potassium transport in plants are described successively,and several typical theoretical systems of how potassium plays a role in plants were discussed.Fifth,it focused on the genetic research of potassium nutrition. On the one hand,it summarized the genetic characteristics of potassium nutrition(the difference of plant potassium nutrition genotype is controlled by heredity;Potassium nutrition traits in plants are controlled by both single gene and multiple genes). On the other hand,recent studies on potassium nutrition heredity at molecular level were summarized. It was found that the studies on potassium nutrition heredity at molecular level focus on gene level and protein level. To sum up,summarizing the research status of potassium nutrition utilization and traits in plants in recent years from five aspects:the general situation and important role of potassium,diagnosis of potassium nutrition,absorption and transport of potassium,and heredity of traits of potassium nutrition. It is suggested to improve and breed new varieties by using modern biotechnology and the genetic characteristics of plants with low potassium tolerance.

Key words: Potassium, Potassium nutrition, Potassium nutrient utilization, Nutritional diagnosis, Characteristics of the genetic
