中文摘要 | 為瞭解本省中部茶園之氣候、土壤自然條件與茶葉產製經營現況,自民國八十年七月至民國八十二年六月在南投、雲林、嘉義縣十三個主要產茶鄉鎮市調查60處青心烏龍及台茶12園品種茶園之茶葉產製情形,並進行土壤、葉片分析及成茶品質鑑定。結果顯示各茶區台茶12號茶菁產量均較青心烏龍為高,海拔愈低品種間產量差異愈大。茶葉產製受經營方式影響明顯,而可依海拔高度大致予以劃分:海拔550公尺以下之台茶12號茶園及海拔450公尺以下之青心烏龍茶園普遍實行機採,施肥量及茶菁產量較高;海拔550公尺以上茶園以手採為主,兩品種茶菁產量差異明顯減小,其平均產量在海拔600-1200公尺之間隨海拔增加而增加,主要原因為夏茶採收比率隨海拔增加而增加,使全年採摘次數隨之增加所致;海拔超過1200公尺以上茶園茶菁產量隨海拔增加而減少,其原因係生產條件受到氣候所限,使茶菁年採摘次數減少所致。茶園土壤調查結果顯示平均土壤pH值僅3.88,較高海拔茶園土壤有機質及交換性鉀含量較高,有效性磷則以施肥量多之低海拔茶園較高。茶樹葉片無機成分含量比較,春茶氮含量平均較秋茶為低,部份茶區氮含量春秋兩季均低於4.00%,葉片鈣含量也普遍低於0.38%,有檢討的必要。包種茶品質綜合比較若以茶季分,春、冬茶明顯優於夏茶;若以海拔高度分,海拔1000公尺以上者平均優於海拔600-1000公尺者,二者又均優於海拔600公尺以下者,但海拔超過1200公尺以上茶區,茶葉之品質並無隨海拔增加而繼續提高之現象。 |
英文摘要 | A general survey on the tea production, its related altitude, soil property, and manipulative management status of totally 60tea plantations in Nantou, Yunlin and Chiaiyi counties around middle Taiwan was conducted during July 1991 to June 1993. Results showed the fresh tea yields from var. TTES No.12 gardens were always higher than that from var. Chin-shin Oolong at the same location, and the yield gap decreased as the altitude increasing. Practical tea productions were highly affected by the management methods and could be roughly divided into 3 zones according to the altitude of the plantations. In the lower zone, mechanized plucking has been widely used in TTES No.12 tea gardens lower that 550 m and in Chin-shin Oolong tea gardens lower than 450 m, both practices were closely connected to high fertilizer application rates and high yield. In the middle zone, hand plucking was the main harvest method used in the tea gardens above the altitude of 550 m, as yield gap between the 2 varieties gradually diminishing, the average yield were used in analysis and a positive relation between yield and altitude from 600 to 1200 m had been observed. An explanation for the relation is that the summer crop harvest rates increased as the altitude increasing, that makes the annual plucking round changeable and affects to the yield. On the higher zone at which tea gardens located higher that 1200 m, however, a negative relation of which tea yield decreasing as the altitude increasing had been found due to the unsatisfactory climatic condition. Result from soil investigation indicated average soil pH was 3.88 in the area. Higher content of organic matter as well as exchangable potassium in tea gardens with higher altitude, and higher content of the available phosphorus in lower altitude with higher fertilization were found. As to the inorganic elements' content of tea shoots, nitrogen content of spring crops appeared to be lower than that of autumn corps, in some locations data less that 4.00% had been found in both spring and autumn corps, which might be induced by unbalanced nutrient application. It was also noted that the calcium content of tea shoots generally less than 0.38%, a criterion being used to considered as insufficiency. A combine analysis of made-tea's quality using "Kruskal-Wallis" test had been applied. Result indicated that spring and winter crops always get better scores than summer crops, and average scores of the tea from gardens higher than 1000 m significantly superior that that from 600-1000 meter's and then alternatively superior than that from under 600 meter's. But result also showed that tea qualities derived from tea gardens in altitude above 1200 m did not get any additional improvement effect. |
