肥培與分蘖多少對香石竹切花品質之影響

Effects of Organic Fertilizer and Number of Side-shoots on the Qualities of Carnation Cut-flowers

本試驗就有機質肥料施用與否研討其與分蘗數對於切花品質之關係。試驗結果如下：（1）有機質肥料之施用與否對花徑大小及花梗長度之差異甚為顯著。（2）每侏分蘗數以10枚為最適。超過10枚之各試驗區，其花徑之大小，花梗與粗度與長度等品質即趨低劣。而低於10枚以下之各試區切花品質殆相同中。（3）花徑大小對花梗粗細與花梗長短之間密切之關係。即花徑大者其花梗必梗必粗而長。

According to the experiences obtained in the past two years from carnation culture on the upland region in Taiwan, it has been realized that the quality of cut-flowers produced in the later part of the blooming season became comparatively poor, therefore we decided to investigate the effect of organic fertilizer and the number of side-shoots on the qualities of cut-flowers. Results are as follows: (1) On the diameter of the flower, -although the difference in effect between the plots with large quantity of fertilizers and those With small quantity of fertilizers was insignificant, yet the difference between the plots with fertilizers and those with no fertilizer at all was notable. (2) The optimum number of side-shoots was found to be 10. That is to say that plants with 12. or 14 side-shoots had their flower diameters and the thickness of their flower stems reduced, and accordingly their market value; while those with 6 or 8 side-shoots had their quality more or less the same as those with 10 side-shoots. (3) The size of the flower diameter bears a close relationship with the thickness and the length of the flower stem, which means that plants with large flower diameter have long as well as thick Stems.
