中文摘要 | 茶園長期施用化學肥料與土壞有機質含量的偏低,導致土壞酸化日益嚴重,尤其紅壤茶園最為普遍,為改善土壤過酸造成的缺點,本試驗採用白雲石粉為改良資材,並配合有機質肥瞪之使用,經三年試驗結果顯示,楊梅與名間二試驗區第一年施用白雲石粉4噸╱公煩對茶菁產量有降低之趨勢,使用白雲石粉2噸╱公頃配合有機肥8噸╱公頃茶菁產量可提高,第二與第三年繼續使用白雲石1噸╱公頃配合有機肥8噸╱公頃茶菁產量較不施或僅施白雲石粉處理區高,所製包種茶品質亦常較佳。施用白雲石粉可提高土壤pH值,交換性鈣與鎂含量,配合有機肥可改善土壤物理性質,促進有益微物生物活動,茶樹生長亦較旺盛。 |
英文摘要 | Owing to constant usage of chemical fertilizer and lack of original organic matter, soil in Taiwan tea garden, especially the red soil have widely been found acidify sharply. For solving defects caused by over-acidifying soil, Trails using dolomitic limestone as mending material, combined with organic fertilizer, were conducted at 2 locations. The 3-year result indicated treatments of 4 tons dolomitic limestone per hectare applied alone tend to decrease the yield of fresh tea leaves, however 2 tons dolomitic limestone combined with 8 tons organic fertilizer per hectare applied tend to increase the yield of fresh tea leaves for the 1st year. While I ton dolomitic limestone plus 8 tons organic fertilizer per hectare consecutively applied tend to increase the yield of fresh tea leaves for the lst year. While I ton dolomitic limestone plus 8 tons organic fertilizer per hectare consecutively applied to the combine treatments in the 2nd and 3rd years, not noly the yield remained superior to that from treatments without dolomitic limestone or with dolomitic limestone applied alone, but also always better in the quality of Poachung tea. Further investigation suggested that tea three might grow more vigorously after the increment of soil pH, soil exchangeable calcium & magnesium content , the improvement of soil physical properties, and the activation of soil beneficial organisms through the application of dolomitic limestone/ organic fertilizer combination. |
