Abstract: [Objectives] To explore the nutrient accumulation characteristics of facility soil in different planting years in the lateritic red soil region of Guangxi. [Methods] The soil samples of facility cultivation and open field cultivation were collected in the lateritic red soil region of Guangxi, and the changes of soil pH, water-soluble salts, organic matter, available nutrients and total nutrients were analyzed. [Results] The acidification of the facility soil in the lateritic red soil region of Guangxi became more obvious with the extension of greenhouse planting years, the soil pH decreased by 0.34 units after continuous planting for 10 years, and the water-soluble content was more than 3 times that of the open field and it increased with the extension of the planting years. In addition, the degree of secondary salinization in facility soil became more serious, mainly moderate and mild salinization. The contents of soil organic matter, alkali-hydrolyzed nitrogen, available phosphorus, available potassium, total nitrogen and total phosphorus in the facility soil increased significantly, while total potassium did not change significantly. [Conclusions] This study is expected to provide scientific basis for facility soil fertilization management, and to promote the sustainable and healthy development of facility cultivation industry.
