Abstract Excess fertilization in facility cultivation brought high nitrate content in soil，led to secondary
salinization，and caused continuous cropping obstacle．Thus，the sustainable development of facility agriculture
was restricted. This paper summarized the research progress on status of nitrate accumulation in facility soil，
reasons，potential risks and hazards. It also expounded the relation between nitrate and crops，and analyzed the
related control measures.
