Precision fertilization plays very important roles for the high yield and high quality in greenhouse vegetable production.Many factors including different planting system，vegetable cultivars，soil fertility，and nutrient input can influence chemical fertilizer reduction and enhancing efficiency technology extension.More than 149 farmer’s greenhouses were randomly picked out from seven counties，which greenhouse vegetable-sown area of each county was more than 6000 hm² in Tianjin city and Hebei province，and totally 212 vegetable growing seasons were surveyed from September 2016 to June 2018.The questionnaire included yield，fertilizer types，application rates and time，application methods and N，P2O5 and K2O contents，and so on.At the same time，149 samples of 0～20 cm soil layer from the investigated greenhouses were collected and organic matter(OM)，nitrate nitrogen，available phosphorus(AP)and available potassium(AK)concentration were measured.The investigation showed that there was a great difference in fertilizer input of each farmer on the same vegetable and planting season，the variation coefficient was more than 40%.In Hebei province and Tianjin city，the average contents of soil nitrate nitrogen，AP and AK in greenhouse vegetable fields were 116.2，287.0，725.1 mg/kg and 256.2，232.2，909.8 mg/kg，respectively，while 42.1% and 60.4% of the soil samples were at high nitrate nitrogen evaluation level(≥100 mg/kg)，92.1% and 91.0% of the soil samples were at high AP evaluation level(≥100 mg/kg)， 100% and 99.1% of the soil samples were at high AK evaluation level(≥200 mg/kg)，and the OM content was in medium fertility(20～30 g/kg)for the two locations.About 20.8%～75.2% and 44.9%～88.3% of current chemical fertilizer input (N+P2O5+K2O)could be reduced in Tianjin city and Hebei province，respectively.On account of the excessive application of chemical fertilizers，richness of soil nutrient and higher fertilizer reduction potential，different strategies of practical fertilizer reduction should be carried out according to field conditions.
