摘要

本試驗於108年秋季進行多個鐵炮型百合族群種子播種，在播種前濕冷層積30日後進行育苗栽培。翌年2月將1,196株鐵炮型百合實生苗栽植於惠蓀實驗林場湯公碑步道入口處並每個月觀察記錄。在2月後雨水漸豐，樹木與小灌木的遮蔭使得未抽莖之鐵炮型百合植株地上部提早消失。至7月時僅1%植株含地上部。於109年10月將經低溫處理兩個月之鐵炮型百合一年生鱗莖1,342顆栽植於湯公碑步道口與翠竹山莊前西向草坡，栽植五個月後仍有68.6%具地上部，養分蓄積較多的鱗莖能提高生存率，且低溫處理後能使植株提早抽莖、生長一致。臺灣原生鐵炮型百合族群以鱗莖經低溫處理後在運輸、栽種與生長表現較佳。本文探討栽植方式及養護管理，增進百合地被栽植開花株比例可行性。

In this experiment, various seeds of longiflorum-type lily groups were sown in autumn 2019. The seeds wer stratified for 30 days before pulation sowing. Total 1,196 longiflorum-type lily seedlings were planted in Hui-Sun Experimental Forest Station of Tanggong Monument entrance in February 2020, the growth was monitored and recorded monthly. Above ground portion of longiflorum-type lily seedlings without shooting were disappeared earlier than excepted because of excessive rains and shade from trees and shrubs nearby and only 1% were left in July. The results suggested that the seedlings had the disadvantages in adapting to the changes in cultivation environment. There were 1342 one-year-old longiflorum-type Lily bulbs planted in the grassland of Tanggong Monument entrance and Cuizhu Mountain Villa with low temperature treatment in October 2020. The results showed 68.6% seedlings had above ground part after cultivation for five months, and the bulbs with more nutrient accumulation can improve the survival rate. Besides, the seedlings also had the advantages of early shooting and uniform growth by low temperature treatment. Taiwan native longiflorum-type lily bulbs had better performance in transportation, planting and growth after low temperature treatment. However, the flowering rate of the one-year-old bulbs were still low for ornamental purpose. It is recommended to use larger bulbs for planting in the future.
