摘要

本研究目的在於探討不同穴格型式（圓型、方型及星型）對甘藍幼苗與定植後生育之影響。試驗結果顯示，在定植前之幼苗以土播苗之園藝性狀較好，不論是莖高、莖粗、葉數、葉面積及地上部鮮重均較各類型穴盤苗為佳，且呈顯著性差異，但不同穴格型式處理者彼此間差異不顯著。定植後第一週的生長速率以圓型穴格苗最高，平均每天分別為大村試區315mg/day，名間試區479mg/day，顯示移植後恢復生長最快速。移植存活率方面，以星型穴格苗表現最佳，達100%；土播苗則最差，僅為68.3～79.1%之間。此外，在甘藍採收期之葉球的橫徑、縱徑及單球重上，各處理間差異均不顯著。在甘藍產量方面，除土播苗處理較差外，其他不同穴格型式處理者差異不顯著。故不同穴格型式所培育之甘藍苗，對甘藍品質與產量之效應並不顯著。

The purpose of this research was to assess the effect of the plug cell shape on the growth of cabbage in seedling stage in field. The experiment was conducted with three shape (round, square, and star) of plug cell, using seedlings in open field bed as control. The field experiments were conducted in Tatsuen and Min-Jian areas under RCBD design with four replications. The results indicated that the horticultural characteristics of control seedlings such as plant height, stem diameter, number of leaves, leaf area and fresh weight were significantly better than that of plug seedlings of all plug cell shape tested. There were no significant differences in the growth of seedlings between different types of plug cell in seedling stage. The growth rate of cabbage obtained from round shape of plug cell was significantly higher than the other treatments at first week, and it was 315 mg/day in Tatsuen and 479 mg/day in Min-Jian, respectively. The survival rate in 100% of cabbage was found in star shape of plug cell treatment and 68.3~79.1% in nursery seedlings which was the highest and the lowest, respectively. There were no significant differences on the horticultural characteristics of cabbage such as head height, head diameter, and head weight between all treatments at harvest stage. The yield of cabbage obtained from nursery seedling was the lowest as compared with other treatments. However, there were no significant differences in the growth and yield of cabbage between the treatments of different shape of plug cell.
