Abstract During facility vegetables production，agricultural science and farming techniques are still not fully applied，unreasonable cropping arrangement and fertilization still exist．This paper conducted analysis on the application status of different fertilization models in Beijing facility vegetables and its production benefit；explored the difficulties in agricultural technology popularization；and put forward corresponding suggestions．The results showed that facility vegetables planting model was mainly monoculture in Beijing，and fertilization model was mainly combined application of chemical fertilizer plus organic fertilizer．Only 13.0% farmer households used soil testing and fertilization techniques．Farmer household’s cognition，whether joining a cooperative，foreign collaboration status，technical cost and whether government subsidies would influence farmer household’s decisions on adopting agricultural technologies．We suggested to accelerate the popularization and application of scientific and agricultural technology，promote efficient use of resources and green development in facility vegetable production by enhancing the cognitive level of farmer households，improving the means of spreading agricultural technology，strethening the exchanges and cooperation between farmer households with universities and enterprises，and perfecting government support mechanism for green transformation．
