中文摘要 | 本研究為明瞭增加肥料施用量對甘藷塊根、莖葉及其所含粗蛋白質及離胺酸含量之影響,而進行田間試驗與化學分析,並研討對甘藷之粗蛋白質和離胺酸產量有利的施肥量。田間試驗種植甘藷高蛋白品種C-64-HP-18和收刈葉品種C-64-HP-4為主區;施肥量採用N0、100、200 kg/ha,K2O 0、120、240 kg/ha之3×3水準為副區的裂區試驗設計,秋植栽培期150天。 由本試驗結果顯示於中等肥力酸性土壤,土質為壤土地區栽培秋植甘藷C-64-HP-18時,每公頃施肥量 N 100 kg,K2O 120 kg可獲較高塊根收量並且生產粗蛋白質和離胺酸為最有利。收刈莖葉品種C-64-HP-4之每公頃施肥量N 200 kg、K2O 120 kg 可獲得最有利的有效莖葉產量及粗蛋白質和離胺酸生產量。 隨氮肥用量之增加,塊根產量有減少趨勢;反之鉀肥用量之增加對塊根產量有增加趨勢。有效莖葉產量則隨氮、鉀肥用量增加而有增加的趨勢。增加氮肥施用量對甘藷塊根或有效莖葉之粗蛋白質和離胺酸含量亦有提高的趨勢。 |
英文摘要 | In order to investigate whether increasing the yields of sweet potato roots and vines by NK fertilizer applications could cause and increase in protein and lysine production, a field experiment and chemical analysis for protein and lysine contents of sweet potatoes were carried out. A high protein cultivar C-64-HP-18 and a cultivar for harvesting stems and leaves (C-64-HP-4) were planted in autumn for 150 days period. The split-plot design was used, with two cultivars arranged on the main plots and 3×3 combinations of fertilizer rates (i.e., 0, 100 and 200 kg/ha nitrogen combined with 0, 120 and 240 kg/ha K2O arranged on the subplots.) The results of field experiments on a moderate fertility loamy acid soil indicate that the dressing of 100 kg/ha nitrogen with 240 kg/ha K2O produced higher root yields associated with maximum protein and lysine production for the high protein cultivar C-64-HP-18. The higher yields of available stems and leaves associated with maximum production of protein and lysine were observed when 200 N and 120 K2O were applied to the cultivar C-64-HP-4. As the rate of nitrogen application was increased, there was a tendency of a decrease in the yields of sweet potato roots; on the contrary, there was a tendency of an increase in the yields of roots with increasing rate of K application. As the rates of nitrogen and potassium application were raised, the yields of available stems and leaves also increased. Increasing nitrogen application also increased the portein and lysine contents of both roots and vines. |
