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: To investigate the botanical morphology and phenophase characteristics of the anti-linkage crop of Salvia miltiorrhiza, in order to provide a reference for the screening of the anti-linkage variety of Salvia miltiorrhiza. Methods: Through field comparative test, Strain, regular observation and data collection and analysis. Results: The resistance of Danshen Danshen anti-linkage strain was significantly better than that of other common strains. According to the growth and development of plants, the phenophase of Danshuai Danshen can be divided into seedling stage, elongation stage, flowering stage, Period, the dead period of six stages of fertility, flowering as the boundary, the anti-Coptis Salvia growth and development is divided into vegetative and reproductive growth. CONCLUSION: According to the appearance and resistance observation, the growth of the selected Salvia miltiorrhiza varieties in the second year of continuous cropping is obviously better than that of other common lines, and has the advantages of anti-streaking.
