以豆瓣菜匍匐茎的上、中、下三段为试材，进行不同茎段的扦插繁殖试验，结果表明，中段成活率高，分枝快，适于做扦插材料。 Taking the upper, middle and lower sections of the stolon of the watercress as the test material, the cutting propagation experiments of different stem segments showed that the mid-section survival rate was high and the branches were fast, which was suitable for cutting materials.
