中文摘要 | 為探討硝酸鉀、硫酸鉀、氯化鉀與其施用量對文旦柚果實品質及產量之影響,於八十四年度在東部地區文旦柚主要產地之花蓮縣瑞穗鄉八年生果園進行試驗。結果顯示,在果實品質方面,果汁量每年以施用硫酸鉀每株0.6kg(含氧化鉀0.3kg)者之156cc為最高,施用氯化鉀每株0.5kg(含氧化鉀0.3kg)者次之,而以施用硝酸鉀每株0.9kg(含氧化鉀0.3kg)者之121cc為最低,糖度以每年施用硫酸鉀每株0.6kg者之12.4Brix為最高,施用量為每株1.2kg者次之,而以施用氯化鉀每株1kg(含氧化鉀0.6kg)者之9.8Brix為最低,各處理間酸度含量之差異不顯著;在果實產量方面,以施用硫酸鉀每年每株0.6kg者之46.3kg為最高,施用量為每株1.2kg者次之,而以施用硝酸鉀每株0.9kg者之35.1kg為最低。綜合本試驗之果實產量與品質而論,文旦柚施用鉀肥種類與其施用量,以硫酸鉀每年每株0.6kg之處理較佳。 |
英文摘要 | This experiment was designed to understand the effects of different kinds(KNO , K SO , KC1) and amounts of potassium fertilizers on the yield and quality of Wentan pomelo. The experiment was conducted in 1995 at Juisui, where is one of the most important Wentan pomelo production areas in Taiwan. In the contents of fruit juice, the results showed the treatment of applying 0.6kg K SO per plant (contained 0.3kg K O) had the biggest volume of fruit juice (156cc/fruit), the treatment of applying 0.5kg KC1 (contained 0.3kg K O ) was the second, and the lowest of that (121 cc/fruit) was obtained from the treatment of applying 0.9kg KNO (contained 0.3kg K O). In contents of sugar, the treatment of applying 0.6kg K SO had the highest value (12.4 Brix), the treatment of applying 1.2kg K SO was the second, and the lowest sugar content was obtained from the treatment of 1.0kg KC1 (9.8 Brix). The results of acidity obtained from all treatments were not significantly different. On fruit yield, the highest amount of production was obtained by the treatment of applying 0.6kg K SO ; the treatment of applying 1.2kg K SO was the second; while the treatment of applying 0.9kg KNO was the lowest. Results suggested that applying 0.6kg K SO plant each year could be the best way to improve the quality and yield of Wentan pomelo, compared with other potassium fertilizers. |
