Abstract:: Taking tomato variety of ‘Fenjia No.17’ as material，a hydroponic culture was carried out to study the element deficiency symptoms，plant biomass，morphology and root-shoot ratio of tomato seedlings on N，P and K element deficiency treatment.The results showed that the element deficiencies had significant effect on growth of tomato seedlings.Plant height，taproot length and plant biomass were obviously decreased under the different element deficiency treatments，but root-shoot ratio of tomato seedlings was increased significantly.Both shoots and roots of plants showed the specific symptoms under the different element deficiencies.The results could provide a theoretical basis for rational fertilization in tomato cultivation.
