中文摘要 | 不同海拔高度及不同pH值土壤之試驗地,栽植4類具有生長潛力,不 同品系的銀合歡:K156(四倍體異葉銀合歡)、K743(異葉銀合歡X巨型銀合歡)、 K636(耐木蝨之巨型銀合歡)、K340(銀合歡),並以廣佈世界的商業品種K8作對 照。四年生的高生長和直徑生長,在不同的試區皆呈顯著的差異。在低海拔(60m) 且土壤pH值5.6-6.2的屏東縣南州試區,K636之生長最佳;低海拔(300m)但土 壤pH值5.1-5.6之臺東縣電光試區,則以K156、 K743及K636生長最佳;海 拔600-750m,土壤pH值5.1-6.0之臺東縣太麻里 (Ⅰ)及高雄縣扇平試區,亦以 K156、K743及K636生長最優,K746及K636次之;高海拔(900m),土壤呈酸 性(pH值4.2-4.4)之太麻里(Ⅱ)試區,以 K156最佳,K743次之。以上述生長資 料視之,K156具抗酸性土壤及耐高冷基因,是極有希望在本省推廣之造林樹種。 在本省廣為栽植的K8(巨型銀合歡)在多數試區生長皆比其他品系差,實宜以其 他品系銀合歡代之。 K636對銀合歡木蝨之侵害恢復力強,低海拔以下及土壤 pH值在5.5-6.2之地區,可栽植K636。 |
英文摘要 | Four accessions of leucaena were introduced and planted on habitats of different elevations and with different soil pH values. The widely distributed commercial accession, K8, was taken as contrast. The 4 year data showed that 5 accessions under analysis were significantly different on each site. At Nan-Chou, 60m elevation and soil pH values 5.6-6.2, K636 performed better than others. At Dien- Guang, 300m elevation and soil of pH5.1-5.6, K156, K743 and K636 observed to be the best. At areas such as Tai-Ma-Li (Ⅰ) and San-Ping of 600-750m elevations with soil pH values more than 5.5, K156, K743 and K636 also had the best yield. However, Tai-Ma-Li (Ⅱ) of 900m elevation and acid soil (pH4.2-4.4), K156 surpassed others. Basis on these data, K156 has potential for high yield and appeares to be the acid soil and cool tolerant accession. Compare with other accessions, the performance of the commercial K8 seems to be in the lowest rank in all locations observed. It is recommended that K636 be chosen for plantation in areas at low elevation (under 500m) with soil pH values 5.5-6.2 and K156 for other kinds of habitats. |
