对山药枝条不同成熟度、不同部位、不同茎节数进行扦插繁种试验比较。试验结果表明，适当提早扦插时间能提高山药插穗的生根率、穗平均生根数；用不同部位的山药枝条作插穗，其生根率、穗生根数、根长有明显差异，以上部枝条效果最好；用1个茎节和2个茎节的山药枝条作插穗，以1个茎节的效果最好，而穗平均生根数，穗平均根长也有差异，但差异不明显。

In the paper, we used the Chinese yam branches of different ripeness degree, parts and stalk node number as cutting branches. The results showed that, the earlier the propagation of cutting branches, the higher the rooting rate and average root number. Scions from different parts had obviously different rooting rate, average root number and root length, and upper branches had highest rooting rate, most and longest roots. The rooting rate of single-stalk-node branches was higher than that of double-stalk-node branches, but their root number and root length had no significant difference.
