In order to master the fertilization and soil fertility status of facility vegetable fields in the suburbs of Beijing，through questionnaires，household surveys，field interviews and field sampling，the in-depth research on the production were conducted.It was found that the average yield of greenhouse tomatoes in the suburbs of Beijing was 82539 kg，the average input of organic fertilizer was equivalent to 200.10 kg of pure N，137.25 kg/hm² of P2O5 and 348.75 kg of K2O，and the average input of chemical fertilizer was equivalent to 429.60 kg/hm² of pure N，294.15 kg/hm² of P2O5 and 483.00 kg/hm² of K2O.The organic matter content of facility soil planted for 0～15 years increased rapidly with the planting years，and then the increase slowed down and remained relatively stable.The organic matter content of facility soil planted for more than 15 years decreased slightly.Soil available phosphorus and available nitrogen content increased first and then decreased with the increase of planting years，and reached the highest value in 11～15 years.Soil available potassium content decreased with the increase of planting years.In terms of soil biological fertility，bacteria were dominant in facility soils with different planting years，followed by actinomycetes，and fungi were the least.With the increase of planting years，the total number of soil bacteria and microorganisms increased first and then decreased，and the total number of bacteria and microorganisms in the facilities with planting years of 11～15 years was the highest.The activities of soil invertase，dehydrogenase and urease decreased with the increase of planting years.In this paper，the current situation of fertilization and soil fertility in facility vegetable fields in Beijing suburbs was preliminarily understood，which provided a basis for scientific management of facility vegetable fields in Beijing suburbs.
