  臺灣重要的花卉作物,主要栽培介質為水苔,現今已可直接帶介質外銷美澳等國,但水苔內常帶有雜草種子,除了在栽培期間發芽造成管理不便,也可能會造成外銷時的檢疫障礙。本研究之目的為探討有效殺滅水苔介質中不同雜草種子之熱水處理水溫及時間,並實地至蝴蝶蘭栽培業者處進行操作,調查熱水處理後的雜草生長情形。試驗結果顯示以熱水處理水苔介質,能有效殺滅燈心草(燈心草科)、水蜈蚣(莎草科)、水蓼(蓼科)等雜草種子活性。而豆科的紫花苜蓿需要較長的熱水處理時間,才能有效殺滅該類種子活性,於業者處進行之試驗亦有相似的結果。

Study of Weeds Seed Control on Cultural Medium for Phalaenopsis

Hsu, S. J. , A. X. Zheng, A. H. Yang, Y. Yang

Abstract

   Phalaenopsis is an important floral crop in Taiwan, and the major cultural medium is sphagnum moss. Now phalaenopsis plants can be directly exported to America and Australia with sphagnum moss. But there are often weeds seeds in sphagnum moss. Seeds generating during culturing will be difficult to manage, and it will also be an export quarantine problem. This research studied the treatment time and temperature of hot water treatment to kill weeds seeds in sphagnum moss effectively. This work would also be practiced in phalaenopsis producer’s greenhouse, detecting the weeds growth condition after hot water treatment. Results showed that seeds activity of Juncus effuses (Juncaceae), Kyllinga brevifolia (Cyperaceae), and Polygonum hydropiper (Polygonaceae) could be killed effectively after hot water treatment. And seeds activity of Medicago sativa (Fabaceae) could be killed after longer hot water treatment. There was also a similar results of experiment practiced in the producer’s greenhouse.
