通过对皇草种茎三种茎段（单节段、二节段和三节段）各节序繁殖效果的研究，结果表明：出苗速度无明显差异，但三种茎段的前三节序均比第四节序出苗快；三种茎段的前三节序茎的成活率和生根速度均高于第四节序，三种茎段及其各节序间在分菜数上无明显差异。单节段、二节段和三节段的繁殖系数分别为：846％，1024％，672％，以二节段最高。
The results showed that there was no significant difference in seedling emergence rates among the three stem segments (single, double and triple) The fourth section of the seedling emergence fast; three sections of the first three sections of the stem survival rate and rooting rate are higher than the fourth section of the three stems and their sections in the number of sub-dishes was no significant difference. The propagation coefficients of single, two and three segments were 846%, 1024% and 672%, respectively, with the highest in two segments.
