新疆蓝刺头属2种植物引种及繁殖方法研究

通过对新疆蓝刺头属的硬叶蓝刺头(Echinops ritro)和天山蓝刺头(E.stjanschanicus Bobr)直接引种及繁殖方法的研究,并田间观察了二种蓝刺头的生长发育规律以及在引种地区的适应性。其结果,硬叶蓝刺头和天山蓝刺头无论在温室,还是露地播种发芽率都很高,根插繁殖以根粗0.5～0.8 cm,0.8～1.1 cm,长2～3 cm的根段生根最好。在引种地适应性强,田间管理粗放,耐寒耐旱,抗病虫害能力强。

Introduction and Reproduction Method of Two Echinops Plants in Xinjiang

We do the research on the introduction and reproduction method of Echinops ritro and E. stjanschanicus, do the observation on their growth and development, and discuss their adaption in the introduction place. The results are as following： （1）E. ritro and E. Stjanschanicus have th the high seed germination rate in green house and the field; （2） the diameter of root cutting repro-duction of E. ritro and E. Stjanschanicus are 0. 5 - 0. 8 cm and 0. 8 - 1.1cm individually, the best length is 2 - 3 cm at the root of the plant. They have the strong adaptability, extensive management, cold and drought resistance, disease and pest resistance ability in the field.
