Abstract: Rhizosphere is the soil microzone affected by the living roots of plants.Rhizoshere nutrition ecology becomes the issue of the day in recent years.This paper reviewed the rhizosphere soil sampling methods,the determination technologies of nutrients of rhizosphere soils,the nutrient status in the rhizosphere microzone and the effects of root exudates on rhizosphere nutrition ecology.In the paper,highlights were given to the rhizosphere soil sampling method used in the field and simulated rhizosphere soil cultivation methods in the lab and three commonlyused rhizosphere nutrition determination technologies,namely,microelectrode,electronic probe and frosting and slicing.Research on the status of N,P and K nutrients in the rhizosphere in past two decades was discussed.The effects of root exudes on the microenvironment near the root,nutrient release and plant adaptability to nutrient stress were analyzed.Some aspects are also proposed that should be emphasized in future research work.
