Effects of different extractions on growth and nutritional quality of hydroponic endivia

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 nutritional quality endivia, as compared modified Hoagland nutrient. The results showed that the root-shoot ratio under all treatment conditions was higher than in CK group. Among them, Ⅳ exhibited best improve efficiency; Ⅰ, Ⅱ, Ⅴ, Ⅵ beneficial reduce nitrate content. Ⅰ significantly increased content VC soluble sugar. protein Ⅴ highest. Above all, application fertilizer extracts actual production hydroponic lettuce needs further deeper research.
