Abstract: In order to understand the current situation and problems of soil fertility and fertilization in the cultivated vegetable areas in Hubei Province, the data of cultivated vegetable fertilization in 5 representative areas in Hubei Province were analyzed. The results showed that 85.54% of farmers applied organic fertilizer to each crop, mainly chicken manure (including undecomposed) and commercial organic fertilizer, accounting for 39.34% and 46.95% of organic fertilizer types respectively. Jingmen City, Xianning City and Wuhan City far exceeded the Ministry of Agriculture and Rural Affairs recommended the upper limit of organic fertilizer application for vegetable commodities in facilities by 497.62%, 186.14% and 109.97%, respectively, while Yichang City and Xiangyang City were lower than lower limit by 16.15% and 63.33%, respectively. The level of fertilizer application was Yichang City> Jingmen City> Wuhan City > Xianning City > Xiangyang City. In Hubei Province, the soil organic matter content was 13.46~44.46 g/kg, the soil pH was 4.84~7.54, the soil salt content was 1.02~3.56 g/kg, and some soil was acidic salinization. Soil alkali-hydrolyzed nitrogen and available potassium contents were 48.89~168.47 mg/kg and 110.00~579.22 mg/kg, respectively, with low, medium and high levels. Soil was rich in available phosphorus, available zinc, exchangeable calcium and magnesium. The available copper content in soil was extremely lacking. In Hubei Province, there were some problems in vegetable fertilization, such as excessive fertilizer input, nutrient imbalance, incomplete decomposition of organic farm fertilizer, insufficient application of medium and trace elements fertilizer, and improper fertilization methods. It was suggested to solve the above problems by improving the way of fertilization, applying organic fertilizer reasonably, reducing the amount of fertilizer applied, adjusting the proportion of fertilizer applied, paying attention to the input of medium and trace elements, and developing and promoting special fertilizer for vegetables.
