| 摘要: |
| 探讨了影响大丽花开花的若干因素。在试验中利用扦插不定芽来繁殖种苗,采取盆栽独本大丽花的方式,分别于5年里的3月至10月间对63个大丽花品种的花期控制进行了研究。将大丽花按开花先后分为早花、中花、晚花三个品种类群;并运用全息生物学基本原理对取自根颈不同部位插穗所繁殖时后代的开花情况进行了分析;确定了营养水平会给大丽花花期早晚带来重要影响。从而总结出控制大丽花开花的具体措施,使其成品出圃率从50%左右提高到80%左右,显著增加了盆栽大丽花的观赏、商品价值。 |

| Abstract: |
| The factors affecting bloom date of dahlia were analysed in this paper.During the test,the shoots were propagated by the adventitious bud cuttings and with the method of single dahlia inflorescence in the pot.From March to October in five years,the controlling bloom date of dahlia was studied with six- ty three dahlia cuhivars among which were divided into three groups.The bloom conditions of the cutting spikes from different parts of the root neck were analysed with the basic holographic biological theory.... |
