[Objective]The aim was to study the methods of improving the rooting rate and quality of Symplocos ramosissima cuttings.[Method]The effects of different growth regulators and seedling substrates on the rooting and transplanting growth of cutting seedlings were studied with S.ramosissima branches as materials,and the suitable base fertilizer application amount of cutting seedlings was screened out to improve the survival rate of cutting seedlings.[Result]The cuttings dipped in the mixed solution of ABT 400 mg/L + IAA 200 mg/L for 30 minutes before cutting could obtain better survival and rooting effect.Selecting 66.7%garden soil + 33.3%coconut bran mixed substrates for transplantation could promote the survival and growth of S.ramosissima cutting seedlings.The best scheme for basal fertilizer application suitable for S.ramosissima cutting seedlings was compound fertilizer 2 g/plant + compound biological agent 1 g/plant.[Conclusion]This study found that suitable growth regulators,seedling substrates,and basal fertilizers for the survival and growth of S.ramosissima cutting seedlings can provide good technical support for the production of S.ramosissima seedlings.
