摘　　要：目的:调查研究白花丹参抗连作品系的植物学形态及物候期特征,以期为白花丹参抗连作品种的筛选提供参考。方法:通过大田对比试验,定株、定期观察并进行数据的采集和分析。结果:白花丹参抗连作品系的抗逆性明显优于其他普通品系,根据植株的生长、发育可将抗连作白花丹参的物候期划分为苗期、伸长期、开花期、结实期、根部膨大期、枯死期六个生育阶段,以开花期为界线,将抗连作白花丹参的生长发育分为营养生长和生殖生长。结论:根据外观特性和抗性观察,筛选的白花丹参品系在连作第2年的生长明显好于其他普通品系,具有一定的抗连作优势。Objective： Morphological characteristics and phenological phase of Salvia miltiorrhiza f. alba for anti-continuous cropping was studied in the field. Methods： The data of fixed plants of different stages were collected and analyzed. Results： The resistance of the strains for anti-continuous cropping was obviously higher than the others. The phenological phase of strains for anti-continuous cropping was divided into seedling stage,elongation stage,flower stage,fructification stage,root enlargement stage and dead stage. The whole development period was divided into the vegetative growth and reproduction growth by the flower stage. Conclusion： From the appearance characteristics and resistance observation,the growth of Salvia miltiorrhiza f. alba for anti-continuous cropping was better than the other strains in the next year.
