Abstract

We used the radish to study the effects of fertilizers combination and nitrogen levels on the nitrate contents and other correlation quality components during the development of them at different seasons. The results showed that different combination of organic and inorganic fertilizers after one week topdressing, the nitrate content of the radish reached to a high level, while the NR activity decreased. Compared with non-fertilizer treatment, the radish with different organic and inorganic fertilizers treatments showed a significantly high contents of nitrate, VC, soluble sugar and soluble protein, the organic with chemical fertilizer as topdressing treatment showed a relatively low nitrate content. Under the different nitro- gen levels, the nitrate content of the radish significantly rised after the topdressing, but the NR activity rised first and then decreased. Compared with the non-fertilizer treatment, radish the nitrate, soluble protein content of radish increased with the increasing of nitrogen application, VC and total soluble sugar content reached maximum at the treatment of constant nitrogen level.
