采用多花黄精根茎繁殖苗在毛竹林冠下进行种植效果比较试验，结果表明：坡向和坡位对多花黄精生长的影响极为显著，以半阴坡和下坡的生长量最高。其中：半阴坡的平均保存率、地径、高、根茎总质量等各项生长指标分别达90.1%、0.54 cm、59.5 cm、1195.7 kg/hm2（干重），下坡的平均保存率、地径、高、根茎总质量各项生长指标分别达91.4%、0.53 cm、58.6 cm、1211.0 kg/hm2（干重）。多花黄精的保存率、高径生长量和根茎质量的高低顺序依次为半阴坡＞阴坡＞阳坡，下坡＞中坡＞上坡。

An effect comparison test was conducted with Hua rhizome propagation seedlings grown under the bamboo canopy. The results showed that the slope direction and slope positions had extremely significant influence on the growth of Hua, and the growth of which on the half shady slope and down slope was the highest. Of which, the growth indicators of those on the half shady slope, such as the average survival rate, average diame-ter, average height and average root total weight, were 90.1%, 0.54 cm, 59.5 cm and 1,195.7 kg/hm2 (dry weight) respec-tively; the average survival rate, average diameter, average height and average root total weight of those on the down slope were 91.4%, 0.53 cm, 58.6 cm and 1,211.0 kg/hm2 (dry weight) respectively. The sequences of the survival rate, high diam-eter growth and roots weight of Hua were as follows: half shady slope>shady slope>sunny slope and down slope>middle slope>up slope.
