Abstract：In order to fully utilize the desert resources in Hexi region,the growth of tomato under different cultivation modes of yellow sand was explored,and the cultivation modes suitable for local production were then selected.This study compared the effects of different treatments on the growth,yield,photosynthetic characteristics,and quality of greenhouse tomatoes by using the integrated technology of water and fertilizer.Three cultivation modes of yellow sand were set up:yellow sand temperature regulated cultivation(T1),yellow sand underground trough cultivation(T2),and yellow sand aboveground trough cultivation(T3),with flat soil cultivation as the control(CK).The results showed that T2 treatment had the highest yield,significantly higher than T3 treatment and CK treatment;T1 and T2 treatments significantly increased individual plant yield,individual fruit quality,fresh underground mass,individual plant biomass,root to shoot ratio,root length,net photosynthetic rate,leaf stomatal conductance,transpiration rate,SPAD,soluble protein,and vitamin C content compared to CK treatments.Compared with CK,T1 and T3 treatments can significantly increase the content of soluble solids and soluble sugars,while T2 treatment has no significant difference.Through grey correlation analysis,T2 treatment has the best comprehensive performance and can be promoted as the best cultivation mode for local greenhouse tomatoes in production.
