防风Saposhnikovia divaricata(Turcz.)Sch-ischk为伞形科防风属植物,主产于东北、华北等地。四川省南充地区药材公司1976年起从黑龙江省富裕县调入当地野生的防风种子,在南充专区苍溪、阆中两县境内种植,先后采用有性繁殖(直播法)与无性繁殖(节栽法)进行引种试验,均获成功。历年试验证明,引种防风的生长期比东北野生品种大大缩短,其中直播法一般经二年后即可采挖,而节栽法的生长期则更短,当年即可受益,颇受当地药农的欢迎。就引种防风的外形而言,直播法所得防
Wind protection Saposhnikovia divaricata (Turcz.) Sch-ischk is a genus of umbrella plants belonging to the genus Umbelliferae, which is mainly produced in the northeast and north China. In 1976, the Sichuan Nanchong medicinal materials company transferred wild windproof seeds from Fuyu County of Heilongjiang Province and planted them in the Cangxi and Langzhong counties in the Nanchong area. Sexual reproduction (live broadcast method) and asexual reproduction (planting method) were successively adopted. ) The introduction trials were successful. Experiments over the years have proved that the introduction of windbreaks is much shorter than the wild species in the northeast, and the live broadcast method can usually be excavated after two years, while the growth season of the section planting method is even shorter. welcome. For the introduction of a windproof shape
