苦土石灰及硼砂的施用對台農13號鳳梨品質之影響
Effect of Dolomite and Borax Applications on the Quality of Tainung No. 13 Pineapple
摘要
經檢測台農13號鳳梨催花前葉片發現鈣、鎂、硼濃度較傳統開英種有偏低情形，因此本試驗乃以不同苦土石灰及硼砂施用量評估對鳳梨果實品質的影響。試驗採三種苦土石灰（0，1，2公噸/公頃）及三種硼砂用量（0，15，30公斤/公頃），共9種處理，於催花前及採收前檢測土壤理化性質及植體營養元素濃度以觀察其變化情形，並於採收期調查果實品質。結果發現，隨著苦土石灰及硼砂施用量的增加，於催花前土壤理化性質及植體營養元素濃度有提昇的趨勢，對於台農13號鳳梨果實一般性狀（果長、果寬、果重等）以不施用苦土石灰而施用硼砂30公斤/公頃有提昇效果，施用苦土石灰2公噸/公頃及硼砂30公斤/公頃對於糖酸比之提昇以及果心斷裂比率的降低則有較佳效果。

Before flower-forced, the calcium, magnesium and boron concentrations were all lower than normal cayneen in Tainung No. 13 pineapple. The different dosages of dolomite and borax were apllied to evaluate the influence on quality and yield of Tainung No. 13 pineapple. Three rates of dolomite (0, 1, 2 t/ha) and three rates of borax (0, 15, 30 kg/ha), 9 different treatments were conducted in this experiment. Before flower-forced, soil physical-chemical properties and plant nutrition concentration were all increased as the increase of rates of dolomite and borax. The fruit length, width and weight were all excellent when non-dolomite and 30 kg/ha borax were applied. The sugar/acidity and the reduction percentage of broken-cored were showen the best in the treatment with 2 ton/ha dolomite and 30 kg/ha borax were applied.
