Abstract：To investigate the fertilization practices,changing trends,and existing problems in facility vegetable production in Beijing's suburbs,and to estimate the potential for fertilizer reduction in facility vegetable production,a total of 365 producers of 7 categories of vegetable crops in 12 suburbs were investigated by consulting statistical data,issuing questionnaires and filling in the fertilization survey system.The results showed that the amount of fertilizer used in facility vegetables decreased compared with that in 2022.The average amount of organic fertilizer per 667 m2 was 2.45 t,which was 9.26%lower than that in 2022.The amount of chemical fertilizer nutrient was 31.16 kg/667 m2,which was 6.02%lower than that in 2022.In facility vegetable production,the total input cost of organic fertilizer and chemical fertilizer was about 1 448.84 yuan/667 m2.There were some problems among facility vegetable growers in Beijing suburbs,such as unreasonable proportion of fertilizer nutrient input,less application of new functional fertilizer,and insufficient attention to medium and trace element fertilizer.In view of the problems found in the survey,some suggestions were put forward,such as guiding farmers to invest in organic fertilizer reasonably and strengthening the upgrading of soil testing and formula fertilization technology,which provided a reference for improving the scientific fertilization level of facility vegetables in Beijing suburbs and reducing the amount of fertilizer used in facility vegetables.
