Abstract:

Raising seedlings is an important part in the production of machine-transplanted aromatic rice. In order to explore the effects of different seedling raising methods on the quality and physiological characteristics of machine- transplanted aromatic rice seedlings, two varieties of fragrant rice (Meixiangzhan 2 and Xiangyaxiangzhan) were selected. In this study two types of seedling-raising trays (bowl seedling tray and hard seedling tray), two kinds of seedling-raising substrate (rice paddy soil and rice seedling matrix), two kinds of seedling-strengthening agents (application of seedling-strengthening agent and non seedling-strengthening agent) were tested in combination. The results showed that the seedling quality and resistance enzyme activity of the fragrant rice seedlings were significantly improved by the application of seedling-strengthening agent and using rice seedling-raising medium. In this experiment, the optimal breeding method is MHT (combination of rice seedling matrix, hard seedling tray and application of seedling-strengthening agent) and MBT (combination of rice seedling matrix, bowl seedling tray and application of seedling-strengthening agent) because these two treatments have the largest biomass per plant and the highest resistance enzyme activity.

Key words: Aromatic rice, Machine-transplanted seedling, Seedling raising methods, Seedling quality, Physiological characteristic
