Abstract:
Taking one-year Salvia miltiorrhiza as test material,1/3 inflorescence length clipping (CI1/3),1/2 inflorescence length clipping (CI1/2) and full inflorescence length clipping (CITotal) at full flowering stage were used as a comparison.The effects of different treatments on the changes of plant biomass,material distribution pattern and inflorescence growth of Salvia miltiorrhiza were studied,in order to provide reference for the rational use of flower thinning measures in production.The results showed that,the plant biomass of Salvia miltiorrhiza was significantly increased by 1/3 inflorescence length clipping treatment (CI1/3),while the plant biomass of 1/2 inflorescence length clipping treatment (CI1/2) and whole inflorescence clipping treatment had no significant changes.The effects of different inflorescence length clipping treatment on the biomass allocation of plant organs mainly showed within 28 days after treatment.The cumulative dominance of CI1/3 root biomass was demonstrated.The inflorescence of whole inflorescence increased continuously after 14 days of pruning treatment,and there was no significant difference in the inflorescence number of CI1/2 after 56 days.Cutting inflorescence promoted the yield of Salvia miltiorrhiza,but had no significant effect on the content of tanshinones and salvianolic acid B.In conclusion,moderate flower cutting treatment can effectively control inflorescence regeneration of Salvia miltiorrhiza plants,facilitate root dry matter accumulation and promote yield increase.
