中文摘要 | 為探討氣壓式鬆土施肥機於東部茶園之適用性,以及深層鬆土及施用液肥對茶菁 生產及茶葉品質之影響,於花蓮縣瑞穗茶區及台東縣鹿野茶區分別進行深層鬆土及深層增施 液肥效果調查。三年試驗結果顯示,機械操作效率受土質影響極大,瑞穗茶區青心大冇試區 土質較鬆軟,深層鬆土作業每點處理只須30秒即可完成,而鹿野茶區台茶12號試區土壤中 石礫含量較高,作業時間每點須時長達2分30秒,兩地效率相差5倍以上,可能成為本機機 械實用上之限制。於深層鬆土同時加施液肥作業每點平均須增加10秒。茶菁收量調查,供試 二品種茶樹於冬茶前及春茶前實施深層鬆土及深層增施液肥處理均有提高茶菁收量之效果, 但第一年差異較不顯著。青心大冇試區兩種參試因子之主效應趨勢一致,均於春茶增加,至 冬茶降低,而全期均以深層鬆土之增產效果較深層施液肥為高;台茶12號試區主效應無明顯 之週期變化,春、夏茶季深層鬆土之增產效果高於深層施液肥之效果,但至秋、冬茶季則以 深層施液肥之增產效果較高。茶菁農藝性狀及茶葉品質調查亦顯示深層鬆土及深層增施液肥 處理具有促進茶菁生長、提高茶葉品質之效果。 |
英文摘要 | On the purpose of understanding the applicability of a multipurpose pneumatic cultivator in tea gardens, experiments were conducted to study the effects of underground scarification and liquid fertilizer injection on tea growth in two eastern tea districts, namely Juisui Hualian and Luyeh Taitung. Results from the 3-year investigation revealed that the efficiency of mechanical operation was greatly dependent on soil properties. For the loamy soil plot (cv. Chin-Hsin Dapan) in Juisui Hualian, it required 30 sec. In one underground dibbling scarifing operation, whereas that of stony plot (cv. TTES No.12) in Luyeh Taitung required 2 min. and 30 sec. Which night become the critical consideration of applicaton. A further operation of injecting liquid fertilizers into deep layer of soil required another 10 sec.. Yields of fresh tea buds were enhanced by both treatments, underground deep layer scarification (DS) & Liquid fertilizer injection (LF), in both varieties. The enhanced effect was ambiguous in the 1st year but became more and more obvious in the 2nd and 3rd years. The main effects of the two experimental factors to the yield of Chin-Hsin Dapan have the same trend as increasing at spring crop and decreasing at winter crop. Yielding effect index of DS were higher than that of LF all the time. As contrast to that, the main effects of the two experimental factrors to the yield of TTES No. 12 did not have obvious periodical fluctuation, however, yielding effect index of DS were higher than that of LF in spring and summer crop, but falled to inferior than yielding effect index of LF in autumn and winter crop Data of agronomic characters of tea buds and qualities of tea leaves also showed an enhancing effect by both DS and LF treatments. |
