Abstract:: In order to raise the seedling efficiency by cutting of Thymus mongolicus in greenhouse in winter，taking the current year branches of T.mongolicus as experimental material，the experiment was designed as 3×5 factorial and arranged randomly，effect of different types of cuttings（top，middle and lower）,different concentrations of ‘strong root powder’on the rooting number，root length，plant height，rooting percentage and seedling percentage of T.mongolicus Ronn.were studied.The results showed that the cutting from the top of branches were significant or very significant better than the other two kinds on the rooting number，root length，plant height，rooting percentage and seedling percentage;for the same type of cutting，the 5 indexes were increasing with the higher concentration of the rooting powder，and then descending with the lower concentration after the 5 indexes were up to the most;the best treatment in all the 15 treatments was the cutting from the top of the branches,after cutting the end of them were dipped in the rooting power solution with 100 mg/L，the rooting number was 25.38，the average root length was 31.00 mm，the plant height was 8.95 cm，rooting percentage and seedling percentage were all 100%.
