| Abstract: |
| In order to investigate the effect of different ridge-furrow film planting patterns under continuously cropped on tuber quality of local cultivar potato “Xindaping” during storage, six treatments including harrowed bedding system without film mulching (CK), harrowed bedding system with film mulching (T1), completely mulched alternating narrow and wide ridges with ridge planting (T2), completely mulched alternating narrow and wide ridges with furrow planting (T3), plastic mulched raised bedding system with bedding planting (T4) and plastic mulched raised bedding system with furrow planting (T5), were conducted. The results from 3 years field continuous cropping experiment indicated that the content of dry matter, starch, reducing sugar, soluble protein, amino acid and Vc of tuber in T2 and T4 treatments were significantly higher than those in others. Content of dry matter, starch, reducing sugar, soluble protein, amino acid and Vc of tuber in 2014 were higher than those in 2013, while organic acid content changed inversely under the 5℃ storage condition. Contents of dry matter, starch, reducing sugar, soluble protein, amino acid and Vc in tuber under 1℃were higher than those under 5℃ storage condition, except organic acid. Considering storage quality of tuber, T2 and T4 were recommended in the pattern of continuous cropping, and high qualities for potato could be maintained under 1℃ storage condition. |
