摘要：The aim of this study is to understand the effect of subsurface drainage on salts of greenhouse soils, tomato yield and quality. Different layout schemes with various pipe depth (0.6 and 0.8 m) and space (6, 8 and 10 m) were designed, the Electrical Conductivity (EC) of topsoil soil during different periods, the tomato yield and the main quality indexes (soluble solids, total acid, vitamin C, sugar/acid ratio) were observed. The results showed that: the topsoil EC values showed a fluctuating decline trend, D2S1 treatment obtained the best results of topsoil salt removing, with the removal rate of 50.87%; the tomato yield of D2S3 was the highest, which reached 128.33 t/hm2; the smaller buried depth and space of drainage pipes increased the concentration of the main nutrients of tomato. If the reduction of greenhouse soil salts were served as the main purpose, the drainage scheme with 0.8 m buried depth and 6 m space could be considered.
