中文摘要 | 唐菖蒲為本省重要切花之一,甚具經濟價值,但其施肥量與施肥方法 尚乏本土性資料可資參考,因此進行本試驗,先探討氮肥及鉀肥用量對唐菖蒲生 長與切花品質之影響。供試之唐菖蒲(Gladiolus grandiflora. cv. Red Beauty)種於台 中縣后里鄉,試驗前之土壤條件為pH 5.1,含有機質2.5%、P 95m/g、K 106m/g、 Ca 437m/g、Mg 87m/g。化學肥料在P2O5固定為200kg/ha的情形下,以氮肥用 量4級(100、200、300及400kg/ha)與鉀肥用量3級(200、300及400kg K2O/ha) 組合進行試驗。結果顯示施不同量之氮鉀肥對株高及葉片數之影響不顯著,花梗 長度,花梗重及花苞數受處理之影響較小;低氮(100∼200kg N/ha)有利於開花, 開花期較集中,瓶插壽命較長;鉀肥用量對切花品質之影響較不明顯;但子球重 量隨鉀肥與氮肥用量增加而增加。亦即在本試驗地之條件下,若以切花品質為重 ,則氮肥之適量為100∼200kg/ha,鉀肥則以200kg/ha為適量。 |
英文摘要 | G1adiolus is one of the important cut flowers that is high in economic value in Taiwan. However the proper rates and methods of fertilization for this crop are still waiting for being established. This experiment was carried out to study the effects of the different rates of nitrogen and potassium fertilizers on the growth of gladiolus and the quality of its cut flower. The test variety was Gladiolus grandiflora cv. Red Beauty. The experiment plot was located at Houli in Taichung Hsien in a lateritic soil with a soil analysis as follows: pH5.1, organic matter 2.5%, available P 95mg/g, extractable K 106mg/g, Ca 437mg/g, and Mg 87mg/g. The 4 levels of nitrogen, 100, 200, 300, and 400kg/ha, and the 3 levels of K2O, 200, 300, and 400kg/ha were combined into a4 x3 factorial experiment for experiment under a fixed rate of 200kg/ha of P2O5. The results of the experiment showed that plant height and leaf number were not significantly different under the different rates of nitrogen and potassium fertilizers. The differences in peduncle length, peduncle weight, and flower number between treatments was very small. The quality of cut flower was significantly affected by the rates of nitrogen and potassium fertilizers. Lower rates of nitrogen (100-200kg/ha) was beneficial to flowering, and the flower was heavier, flowering stage was more concentrated, and the bottle life was longer. Higher rate of nitrogen (400kg/ha) got bigger and lighter flower with shorter bottle life. However the yield of the tuber increased with the increased rates of nitrogen and potassium fertilizers. The proper rate of nitrogen for the gladiolus in this soil is 100-200kg/ha, and potassium is 200kg/ha. |
