摘要: 本研究針對花蓮地區馬太鞍、太巴塱及林田山3地不同海拔之包籜矢竹林分,進行不同海拔之生長特性調查分析。林田山試驗地(海拔高955 m)包籜矢竹林分密度為27.0 ± 5.2 culm m^(-2),竹稈基徑平均0.9 ± 0.3 cm,稈高平均3.1 ± 1.1 m,地上部生物量乾重40.0 ± 10.2 ton ha^(-1),地下部生物量乾重52.5 ± 7.5 ton ha^(-1);馬太鞍試驗地(海拔高362 m)包籜矢竹林分密度為16.7 ± 1.5 culmm^(-2),竹稈基徑平均1.6 ± 0.3 cm,稈高平均5.2 ± 1.0 m,地上部生物量69.8 ± 23.7 ton ha^(-1),地下部生物量105.2 ± 14.8 ton ha^(-1);太巴塱試驗地(海拔高150 m)包籜矢竹林分密度32.7 ± 7.2 culm m^(-2),竹稈基徑平均1.29 ± 0.3 cm,稈高平均4.6 ± 0.9 m,地上部生物量乾重84.8 ± 14.4 ton ha^(-1),地下部生物量乾重48.6 ± 11.2 ton ha^(-1)。本研究結果顯示,以馬太鞍地區生長表現較佳,其次為太巴塱地區,最差為林田山地區。而竹林出筍產期,則易受雨量及溫度影響。
This study investigated the growth of Pseudosasa usawa at Mataan (馬太鞍)、Tabalong (太巴塱) 及Lintiensan (林田山) in Hualien areas. Results showed that on the Lintiensan site with 955 m at the elevation, the culm density is 27.0 ± 5.2 culm m^(-2) with 0.9 ± 0.3 cm in culm diameter, 3.1 ± 1.1 m in culm height, 40.0 ± 10.2 ton ha^(-1) in biomass above ground, and 52.5 ± 7.5 ton ha^(-1) in biomass underground;on the Mataan site with 362 m at the elevation, the culm density is 16.7 ± 1.5 culm m^(-2) with 1.6 ± 0.3 cm in culm diameter, 5.2 ± 1.0 m in culm height, 69.8 ± 23.7 ton ha^(-1) in biomass above ground, and 105.2 ± 14.8 ton ha^(-1) in biomass underground;on the Tabalong site with 150 m at the elevation, the culm density is 32.7 ± 7.2 culm m^(-2) with 1.29 ± 0.3 cm in culm diameter, 4.6 ± 0.9 m in culm height, 84.8 ± 14.4 ton ha^(-1) in biomass above ground, and 48.6 ± 11.2 ton ha^(-1) in biomass underground. Comparison the performance of growth among three sites showed that the growth on Mataan area is the best, followed by growth on Tabalong area and by growth on Lintiensan area. The period of bamboo shoot production was influenced by the precipitation and temperature.
