Abstract
夏季設施內高溫影響花椰菜穴盤苗的生長，植株常表現較小及根團發育不佳。本研究評估穴盤表面覆蓋與穴盤底部控溫對花椰菜苗生長的影響。利用泰維克布覆蓋穴盤表面以減少介質的裸露，當穴格表面覆蓋90.8% 的面積時，幼苗品質指數與Dickson 品質指數最佳，優於覆蓋面積86.7% 與82.0%，無覆蓋的穴盤的苗品質最差。在無覆蓋泰維克布的條件下，底部控溫15℃、20℃ 與25℃ 處理的幼苗品質指數與Dickson 品質指數明顯著優於傳統穴盤育苗，但3 個溫度處理間的品質指數並無顯著差異。覆蓋泰維克布結合底部控溫25℃ 的幼苗品質指數與Dickson 品質指數明顯著優於傳統穴盤育苗。於底部進行控溫處理時，有覆蓋泰維克布的幼苗品質指數與Dickson 品質指數皆明顯較無覆蓋處理佳。覆蓋泰維克布結合底部控溫除了可有效降低根域介質的最高溫與平均溫度，同時可縮減根域溫差與溫度的波動，有助於提高花椰菜穴盤育苗的品質。
High temperatures affect the growth of cauliflower seedlings of plug trays in summer. Plants often showed small size and poor root ball. This study carried out the effects of surface covering and bottom temperature control in plug tray for cauliflower seedlings production. The surface covering with Tyvek mulch reduce the exposure of the medium. The seedling quality index and Dickson quality index of the 90.8% coverage area treatment was significantly higher as compared to the 86.7% and 82.0% coverage areas treatments. The quality of seedling without covering showed lowest values. When treatments not combined with Tyvek mulch, the seedling quality index and Dickson quality index of the bottom 15℃, 20℃ and 25℃treatments were significantly better than traditional plug tray seedlings. There was no significant difference in the quality index among three temperature treatments. Plug surface coverage treatments combined with the bottom 25℃showed better performance than traditional plug tray seedlings in seedling quality index and Dickson quality index. Comparison of seedlings differences between coverage and without coverage at a single bottom temperature. The results showed that growth indicators of coverage treatment were higher than without coverage. Covering with Tyvek mulch combined with bottom temperature control reduce the maximum and average temperatures of the medium, but also reduce the temperature difference in the root zone. Plug surface coverage combined with the bottom temperature control improve the quality of cauliflower seedlings.
