摘要：
Soil secondary salinization has seriously affected the greenhouse vegetable production in China. Tomato was used to study the effects of adding bio-organic fertilizer combined with subsurface drainage on soil electrical conductivity (EC), soil quality and yield in this paper. The results showed that application of bio-organic fertilizer could improve tomato quality including soluble solid content and sugar acid ratio. Among all treatments, the available nitrogen, available phosphorus and available potassium were the highest in M1(chemical fertilizer without subdrainage) and the lowest in M4(bio-fertilizer with subdrainage) in 0-20 cm soil layer. The yield of tomato in M4 was 5.60% higher than that of M2 (bio-fertilizer without subdrainage), and 44.54% higher than that of M1. The desalination rates in different treatments at 0-40 cm of soil profile followed the order of M1(3.95%)< M2 (19.86%)< M3 (27.01 %)< M4 (40.16%).
