厚朴种子园植株密度与母树生长关系初步研究

Preliminary Study of the Relationship between Density and Mother Tree Growth of Magnolia officinalis in Seed Orchard

在厚朴(Magnolia officinalis)种子园建设中,通过不同的厚朴母树植株密度对比试验表明,厚朴母树植株密度与母树生长关系密切,厚朴母树植株密度直接影响着母树的胸径生长、树高生长和树冠生长,影响着厚朴母树的结果率和挂果量,从而影响着种子园的结果量。

Comparision test was conducted on different mother tree densities in seed orchard of Magnolia officinalis. The results showed that there was a strong relationship between tree density and growth. The density of mother tree had significant influnce on DBH, height and crown growth as well as fruiting ratio and quantity of mother tree.
