| 摘 要： | 通过调查构树幼苗期6个构件的生长情况及生物量变化,依据Harper的构件理论,对构树苗期种群构件进行了分析,结果表明:构树幼苗构件之间及构件与个体之间生物量增长不具同步性;构树苗期各构件生长发育在8~10月份较为活跃,因此,若需培养壮苗,应在该段时期内加强水肥管理。此外,阐明了构树苗期构件的生长规律,为进一步研究构树,培育及经营其林分提供了参考。

| Abstract: | The growth situation and biomass changes of 6 modules of annual Broussonetia papyrifera seedlings were investiga-ted, and the population modules were analyzed according to Harper ’s module theory.The results indicated that the increase of bio-mass among 6 modules or between module and individual was out of sync .The growth and development of all modules were relatively active from August to October , so it was necessary for cultivating strong seedlings to strengthen water and fertilizer management in this period.In addition, the growth law of Broussonetia papyrifera seedling modules was clarified in this study , which could provide theoretical basis for the further study , cultivation and management of Broussonetia papyrifera. |
