Heavy metals are the most prominent problem in soil pollution in China.At present，a large number of cultivated soils polluted by heavy metals need to be used safely.Heavy metal leaf surface resistance control agent products are widely used in the process of safe utilization of contaminated farmland because of their advantages such as good application effect，simple operation，controllable cost，and no secondary pollution to the soil.This paper summarized the research and application status of leaf surface resistance control agent from three aspects of main species，inhibition and control mechanism and application effect，and pointed out the shortcomings of leaf surface resistance control agent as a new exogenous inhibition and control technology，as well as the direction of future research and application，to provide a scientific basis for the safe use of heavy metal contaminated farmland soil in China.
