摘要

本研究目的係於小花蕙蘭帶介質外銷之集運過程中，探討不同根系修剪方式及不同栽培介質等處理之影響效應，以供日後建立小花蕙蘭帶介質外銷栽培管理及貯運技術之參考。試驗包括4種根系修剪處理，分別為(A)根系未修剪；(B)根系修剪後長度為3.5吋盆高度(15.2 cm)之1/2；(C)根系修剪後長度為3.5吋盆高度之3/4；(D)根系修剪後長度與3.5吋盆高度一致；以及3種栽培介質處理(水苔、椰纖及花生殼)。經不同根系修剪處理及後續6個月的栽培，四季蘭'虹河'的株高、地上部及根部的鮮重以處理D高於其他處理。報歲蘭'山川'植株生長性狀在不同根系修剪處理間無一致趨勢，根部鮮重及乾重則以根系未修剪之處理A及處理D較高，且兩理處間差異不顯著。經過不同介質處理及後續6個月的栽培，報歲蘭'大勳'除了植株新成熟芽數以水苔介質較高，植株新芽數及葉數、根鮮重均以椰纖介質及水苔介質較高，且兩者間無顯著差異。因此，在小花蕙蘭帶介質外銷集運過程中，將根系修剪後長度與3.5吋盆高度一致，是較適宜的修剪方式；椰纖及水苔均為合適的介質種類。

The objective of this study is to develop proper potting and shipping managements for exportation of oriental cymbidium. Experiments were conducted with four root cutting treatments (A (CK): blank; no cutting on roots, B (1/2): roots were cut to 1/2 of pot height (15.2 cm), C (3/4): roots were cut to 3/4 of pot height (15.2 cm), D (1/1): roots were cut to the same height as the culture pot, and three substrates (coir, peanut shell, sphagnum moss). The results indicated that the plant height, shoot fresh weight and root fresh weight of Cymbidium sinense 'Hong-he' on root cutting treatment D was higher than that of other treatments after a 6-month cultivation period. There were no significant performances among root cutting treatments on the growth characteristics of Cym. sinense 'Shan-chuan'. The root fresh weight and root dry weight of Cymb. sinense 'Shan-chuan' in both of root cutting treatment A & D were higher than that of other treatments, and there were no significant differences between root cutting treatment A & D. The number of new mature bud of Cym. sinense 'Da-shin' in sphagnum moss treatment was higher than that of other treatments after a 6-month cultivation period. The number of new bud, number of leaf and root fresh weight of Cym. sinense 'Da-shin' on coir and sphagnum moss was higher than that of peanut shell, and there were no significant differences between coir and sphagnum moss. Therefore, the results could be coordinated with the facts that root cutting treatment D and coir or sphagnum moss are suitable for the potting and shipping management in the exportation process of oriental cymbidium.
