中文摘要 | 為探討改善排水及氮鉀用量對釀酒葡萄產量及品質改進的效應,自 1984年開始連續三年期,於二林鎮進行田間試驗。試驗結果顯示,暗管排水比 地面排水對葡萄夏果增產1.1%至2.3%,糖度提高0.28°至0.65°Brix,產量經變 方分析結果處理間差異達顯著水準。暗管排水區施用N 100kg/ha及K2O 250kg/ha 的產量最高,分別比地面排水區增產5.5%至7.9%及0.3%至3.6%。應用N 200 kg/ha及K2O 350kg/ha的糖度最高,分別提高0.55°至1.50°Brix及0.73°至1.46° Brix;酸度較低,分別降低0.01g至0.03g及0.02g至0.03g/100ml。三年平均的 氮鉀處理組合間以施用150∼350kg/ha(N-K2O)區產量較多,增產0.8%至4.1%, 200∼350kg/ha(N-K2O)糖度較高,提高0.09°至0.55°Brix,酸度較低,降低0.02g 至0.04g/100ml。根據迴歸分析顯示,施用N 135kg/ha配合K2O 350kg/ha時,對 金香葡萄產量及品質均最好。經濟收益比較顯示,氮素施用N 100kg/ha暗管排 水處理組合區比N 150kg/ha地面排水處理組合區增加34,715元/ha的收益,鉀素 施用K2O 350kg/ha暗管排水組合區比K2O 350kg/ha地面排水處理組合區增加 52,656元/ha的收益。本省栽培釀酒葡萄全體果農每年估計將可增加八千萬元以 上收益,若包括鮮食葡萄則將增加二億六千萬元以上收益。 |
英文摘要 | The purpose of this study was to improve the quality and yield of Golden Mustcat grapes by the managements of nitrogen, potassium and tile drainage. Experiments were conducted in Erh-lin soil series, Chang-hua Hsien, from 1983 to 1986. The results showed that yield and sugar contents were significantly improved by the tile drainage. Fertilizer application of 100 kg/ha nitrogen and 350 kg/ha potassium hidroxide gave the highest yield, 200 kg/ha nitrogen and 350 kg/ha potassium hidroxide had the highest sugar content and lowest total acidity.Application of 100-250 kg/ha (N-K2O) gave the highest yield. Plots treated with 200-350 kg/ha (N-K2O) had a higher sugar content and lower total acidity of fruit juice. Regression analysis showed that 150 kg/ha of P2O5, 135 kg/ha of N, and 350 kg/ha of K2O effectively increased sugar contents and reduced acidity of grapes, using either tile or surface drainage. |
