| 中文摘要 | 試驗期間民國71年至77年,試驗樹種5種(見表2),栽培地點3處(見 表1)。以樹種為處理,在不同地區造林,每一地區按逢機區組設計,重複 4次, 進行試驗,結果如下:三個栽培地區,五種桉樹之合計平均生長量,以太麻里最 大,成功最小。各種桉樹之生長表現,為隨地區而異;在太麻里地區,玫瑰桉生 長最佳,青皮桉最差;成功、水璉地區,青皮桉生長最好,而玫瑰桉角萼桉生長 較差。各栽培地區之桉樹,均曾遭受風害,其中成功地區之風害較烈,各樹種受 風害情形為,玫瑰桉、角萼桉風害較重,青皮桉受害較輕。材積生長,樹齡6.5 年之桉樹,以生長優良之單株估算,可達經濟利用之標準,實際單位面積平均材 積年生產量,照目粗放經營方式,在短伐期內,得不到商業利用之價值。 |
| 英文摘要 | This experiment was carried out from 1982 to 1988 at 3 locations of eastern Taiwan; five species of eucalypts, each as a treatment, were arranged in a random block with 4 replications. Spacing was about 2m apart with 3m at intervals. The planting density was 10 plants in plot (60m^2) equivalent to 1,200-1,700/ha. The results indicated that, in the three planting locations, the total mean growth and survival of eucalypts at T'ai-Ma-Li is the best, and Ch'eng-kung is the worst. The growth and development of eucalypts depend primarily on planting sites. At T'ai-Ma- Li, where the elevation is higher, the growth of Eucalyptus grandis is the best and has a higher survival rate; in Ch'eng-Kung and Shui-Lien, the site conditions are most suitable for the planting of E. torelliana. However, since the Ch'eng-Kung region was frequently subject to strong winds, E. Tereticornis and E. grandis were heavily damaged by winds but E. torelliana was only slightly damaged. In order tounder stand the growth potentiality of eucalypts cultivated in east Taiwan, data of recent measurements indicate that the volume growth of the best individuals grown over a 6.5-year period are achieving the standard merchantable size; however, in reality, accouding to the present rougn practice, the annual average volume growth will not meet the commercial scale in a short cutting cycly. |
