In recent years,the soil ecosystems had degraded severely in greenhouse vegetable cultivation.A series of problems such as soil compaction,acidification,salinization and continuous cropping obstacles have appeared gradually with the extension of planting years.Bio organic fertilizer provides a new way for the repair of greenhouse vegetable soil obstacles.Application of bio organic fertilizer in long term can improve soil fertility,change soil physical and chemical properties,regulate soil microbial community structure and accelerate ecosystem restoration.This paper introduced the current problems in facility vegetable soil,summarized the effect and mechanism of bio organic fertilizer on the degraded soil.Finally,the future trend for bio organic fertilizer development and research activities was discussed.
