Abstract

In this study, Hydroponic endivia with completely decomposed distiller’s grains, tea residue and extraction of commercial organic manure were applied to study its effects on growth and nutritional quality of endivia, as compared with modified Hoagland nutrient. The results showed that the root-shoot ratio of endivia under all treatment conditions was higher than that in CK group. Among them, treatment Ⅳ exhibited best improve efficiency; the treatment of Ⅰ, Ⅱ, Ⅴ, Ⅵ were beneficial to reduce the nitrate content. The treatment Ⅰ significantly increased the content of VC and soluble sugar. The soluble protein content of treatment Ⅴ was the highest. Above all, the application of tea residue and commercial organic fertilizer extracts in the actual production of hydroponic lettuce needs further and deeper research.
