Abstract Cucumber is a kind of vegetable prefer warm environment．Low temperature and high air
humidity are the main adverse factors and often coexisted for cucumber facility production during winter
and spring in China．Under the combined action of wet and cold factors， a typical wet-cold microclimate
in agricultural meteorology is formed，which is the main obstruction factors for cucumber production
in facility during winter and spring．This paper firstly puts forward the concept of cucumber wet-cold
environment by reviewing document literature and production practice；then sketches the research progress
and methods for cucumber cold tolerance；reviews the research progress of plant wet tolerance and wet-cold
tolerance，and analyzes the effect of high air humidity and wet-cold environment on cucumber growth and
development．Before ending the paper puts forward problems facing cucumber wet-cold tolerance research
and future prospects，aiming at promoting the studies on cucumber wet-cold tolerance and its identification
technique，and providing reference for wet-cold tolerance breeding and cultivation．
