The purposes of the study are to find the primary causes of physiological diseases in facility vegetables, reduce the waste of chemical fertilizers and soil environmental pollution, and promote the sustainable development of the facility vegetable industry in western Liaoning. This study collected and analyzed 82 soil samples from 4 major production areas (Beipiao City, Heishan County, Yixian County, and Fuxin County) in western Liaoning. The results indicated that the soil pH in all 4 regions was neutral, with abundant total nitrogen, total phosphorus, and total potassium, and high levels of available nitrogen. However, available phosphorus levels were low in Beipiao City and Yixian County, while organic matter content was high in Heishan County and Fuxin County, and was moderate in Beipiao City and Yixian County. Calcium levels were generally low in all 4 regions, while magnesium levels were excessive, and the soils were all saline. It should appropriately increase the application of organic fertilizers such as farmyard manure, compost, and green manure to enhance soil organic matter content in Beipiao City and Yixian County. Meanwhile, it should reduce chemical fertilizer, increase microbial fertilizer application, and appropriately supplement trace elements, and reduce the concentration of salt ions in the soil in all 4 regions with measures such as crop rotation, stubble return, and other practices.
