| 摘 要： | 对７４株１０年生泡桐主干与树冠生长相关关系进行了调查，并利用回归分析方法建立了主干与树冠生长的数学模型，经实例分析检验表明，培养１０年生主干高６．０ｍ，胸径３０．６２ｃｍ的泡桐树需要８．１６ｍ和７．６０ｍ的冠幅和冠高，泡酮的合理干冠比值为０．７９，该模型切合生产实际，为泡桐高干定向培育提供了理论依据。

| Abstract: | This paper dealt with the mathematical model between paulownia stem height and its crown with regression analysis through investigating the growth of stem height and crown of 74 10-year-old trees. The results showed that it required 8.16 m crown diameter and 7. 60 m crown height to foster 10-year-old paulowina with 6. 0 m stem height and 30. 62 cm breast height diameter. The rational ratio of main stem height to crown diameter was 0.79. this model was integrated with practical production and laid a theoretical foundation for the directive breeding of highly stem paulownia tree. |
