| 摘 要： | 通过对泡桐开花过程中相关生理及生态指标的测定,探讨整个开花物候期过程中花器官营养消耗动态,为制定泡桐的适生栽培技术提供依据。试验表明,泡桐在花器官形成和开花过程中,要从根和枝中大量调集贮藏的无机和有机营养物质。小花开绽前对树木进行修剪比在盛花期进行修剪花器官干物质消耗减少53%,粗蛋白消耗减少56%,全糖消耗减少71%。

| Abstract: | This paper deals wih the quantificational determination on the p hy silogical and ecological items of the paulownia(Paulownia tomentosa(Thunb.)S teud.)during its flowering process,probes into the nutrition consuming patter n of its whole florescence in order to provide experimentation basis for the fur ther research of appropriate culture technology.It has been tested that paulown ia consumes a lot of organic and inorganic nutrition coming from its roots and b ranchs during its flowering. |
