| 摘 要： | 为提高厚朴造林质量，开展了苗木地径、亩高与厚朴幼树生长关系的研究，结果表明：厚朴苗木高度对幼树生长无明显的影响，苗木过高反而会降低造林成活率；苗木地径大于0．9cm时，地径对幼树生长也无显著的影响。因此，厚朴苗木不宜以苗高为分级依据。厚朴苗木的适宜高度可从便于起苗、运输、栽种等生产环节来确定。厚朴苗木地径的分级，优质苗的下限也不应大于0.9cm。

| Abstract: | In order to raise afforestation quality, relationship between ground diameter and height of Magnolia officinalis seedlings and its growth was studied. The results showed that, height of Magnolia officinalis seedling had no significant effects on growth of young trees, and extensive height could decrease its afforestation survival. When it was larger than 0. 9cm, ground diameter didn't yet significantly affect the growth of young trees. Therefore, it was not suitable to select height of seedling as classification basis. Optimum height should be determined by production links, such as tree balling, transportation and planting. The lowest limit of ground diameter of fine seedling should not be larger than 0.9cm. |
