摘要

本試驗目的在於探討不同甘藍品種（初秋、夏峰、春秋1號），以及應用不同肥料處理（F1：對照組不施肥料；F2：N-P2O5-K2O，20-20-20；F3：N-P2O5-K2O，31-10-10）對夏作甘藍穴盤苗品質之影響。試驗結果顯示，以不同品種而言，綜合甘藍苗之生育性狀、壯苗指數及幼苗絕對生長速率G值等指標，均顯示春秋1號及夏峰較適於本省平地夏作育苗栽培。以不同肥料處理而言，F3處理之甘藍苗在株高、葉數、葉面積、地上部鮮重、葉長及葉寬等性狀均有顯著效果，惟F2處理之壯苗指數及幼苗絕對生長速率G值均能維持穩定增加趨勢，顯示其幼苗生長勢較均勻，因此應以施用F2處理之甘藍苗的品質較優。綜合本試驗結果亦顯示，利用壯苗指數及幼苗絕對生長速率G值等複合性指數，適用於甘藍穴盤苗品質評估指標。

The objective of this research was to study the effect of fertilizers on the quality of plug seedling in different cabbage cultivars. Experiment with three cultivars (K-Y, Kaiya, Chun-Chon No. 1) and three fertilizer treatments (F1: control; F2: N-P2O5-K2O, 20-20-20; F3: N-P2O5-K2O, 31-10-10) were conducted in summer season in central Taiwan. The results showed that there were good responses on the growth, seedling index and G value of absolute growth rate (AGR) for plug seedling of Chun-Chon No. 1 and Kaiya. It indicated that the cabbage plug seedling of Chun-Chon No. 1 and Kaiya were satisfactorily sown in summer season in the central Taiwan. Significant differences were found on the plant height, number of leaves, leaf area, shoot fresh weight, leaf length, and leaf width of cabbage plug seedling in different fertilizer treatments. The positive effects were obtained from three fertilizer treatments, the best one is F3 treatment and followed by F2 and F1 treatment. However, as considering the balance of seedling index and G value of AGR of cabbage plug seedling, the best treatment is F2. From the above results, it indicated that both seedling index and G value of AGR could be utilized to evaluate the quality of cabbage plug seedlings.
