Abstract：As a high yielding and high efficient cultivation method，substrate culture also has some
shortcomings such as physiological disorder，yield decline and quality losses，causes by salt accumulation in
rhizosphere．This paper made a comprehensive analysis on the factors causing salt accumulation in rhizosphere in
substrate culture，including environment，nutrient solution，properties of nutrient ions and substrate types，etc.
This paper also prospected the future research orientation.
