| 摘 要： | 为了弄清楚有效积温对菊花生长发育的影响并及时采取有效的田间管理措施，采用大田试验，研究了植株地上部干物质、叶片干物质及茎干物质与有效积温的关系。结果表明：菊花移栽至大田后，其植株地上部干物质、叶片干物质及茎干物质增长过程与有效积温的关系均符合Logistic方程所描述的曲线；植株地上部干物质、叶片干物质及茎干物质增长盛期的转捩点（起止点）所对应的有效积温值范围分别是：1248.5~2071.6℃，897.4~1628.9℃，1234.0~1909.3℃。最大瞬时增长速率（Vmax）分别是：0.176 g/（d·℃·株），0.057 g/（d·℃·株），0.1024 g/（d·℃·株）。分别出现在移栽后有效积温达1660.1℃，1263.2℃，1571.7℃之时。

| Abstract: | In order to make clear the effect of the effective accumulation temperature to chrysanthemum growth and adopt effective manage measure, we did the field experiments.The results of field experiments in 2006 indicated that, the relationship between the dry matter accumulation of aerial parts and leaf and stem in chrysanthemum and the available accumulation temperature was transplanted met the Logistic equation. The ranges of the effective accumulation temperature for the turning points of boom stage were: 1248.5~2071.6℃ and 897.4~1628.9℃and 1234.0~1909.3℃ respectively. The highest instantaneous growth rate was 0.176 g/（d ℃·plant） and 0.057 g/（d ℃·plant）and 0.1024 g/（d ℃·plant） respectively; and they appeared when the available accumulation temperature reached 1660.1℃，1263.2℃，1571.7℃ respectively, after transplantation. |
