头顶一颗珠地下根茎无性繁殖研究

Research of Vegetative Propegating Trillim Tsch Onskii Maxim Underground root

头顶一颗珠为国家二类保护植物，又为名贵药材，其根茎无性繁殖比种子有性繁殖缩短生育期２ａ；从出苗到入药提早１２ｍｏ；平均单株根茎干重增加６％；无性繁殖系数可达１０～１２。

s Trillim tsch onskii Maxim is second grade protect plant of China and rare medicinal herbs. By vegetative propagation the root grow period is 2 years shorter thar sexual propagation, the time from seed to gathering is 12 mo earlier, and the average single weight increase 6%. The vegetaive propagational coefficient achieves 10-12 it's valuable in produce.
