摘　　要：目的评价50份丹参杂交品系在丹参连作3年的土壤中农艺性状状况。方法在丹参连续种植3年的基地进行杂交品系移栽,调查分析成活率、根粗、根长、根条数、鲜根重和病害情况等指标。结果50份杂交新品系在丹参连作土壤生长过程中成活率和根部性状差异明显,6个杂交品系植株全部死亡,其他品系结合根部性状鉴定,得到7份综合抗性较好的杂交新品系。结论筛选出7份完全成活、无病害、产量较高的耐重茬优良品系,为丹参连作障碍提供品种支撑。Objective The agronomic characters of 50 Salvia miltiorrhiza hybrid lines were investigated and evaluated,which were planted in 3-year continuous cropping soil.Methods The 3-year continuous cropping base was selected to transplant the hybrid lines of Salvia miltiorrhiza Bge.The indicators such as survival rate,root diameter,root length,root number,root fresh weight,diseases and pests were analyzed.Results There were obvious differences between different hybrid lines in survival rate and root characters when grown in continuous cropping soils.In which,6 hybrid lines were all dead.Combined with the identification of root characters,7 ones with better comprehensive resistances were selected from the other hybrid lines.Conclusion Seven hybrid lines with better tolerance to continuous cropping were screened out,which had 100%survival rate,no diseases and pests,and higher yield.
