Facility agriculture is an important direction of China’s agricultural strategic structural adjustment,which has greatly improved farmers’income and achieved remarkable social and economic benefits.However,in the process of facility agriculture development,its special ecological environment and unreasonable water and fertilizer management measures lead to a series of soil degradation,which affects crop growth.The problems and harms of soil acidification and secondary salinization in facility agriculture are analyzed in this paper,and then corresponding improvement strategies are put forward to provide ideas for the sustainable development of facility agriculture.
