| 摘要 | [Objectives] This study adopted a three-factor three-level orthogonal design to explore the effects of different application periods and methods of fish protein peptide on the fruit quality of 'Tieshanzha'. [Methods] Factor A was set as the application period, with three levels: fruit-setting stage, core-hardening stage, and pre-coloring stage. Factor B was set as the application method, with three levels: root application, foliar spray, and root application + foliar spray. Factor C was set as the application concentration, with three levels: 0, 5, and 10 ml/L. [Results] Application period had an extremely significant effect on single fruit weight. Fertilization at the fruit-setting stage showed a single fruit weight as high as 13.36 g, which was 27.9% and 24% higher than those achieved by fertilization at the core-hardening stage and the pre-coloring stage, respectively. The factor that had the greatest impact on the internal quality of hawthorn fruit, specifically the Vc content, was application method. The optimal combination was foliar spray at the core-hardening stage with a concentration of 10 ml/L, which achieved the best fertilization effect. [Conclusions] This study provides a theoretical basis for improving fruit quality of 'Tieshanzha'. |
