Abstract: In this study, the effects of soilcovering thickness and sowing time on the emergence rate and seedling growth of [WTBX]Quercus wutaishanica,[WTBZ] a kind of natural secondary forest on the Loess Plateau, were researched. The results were as follows: ① Soilcovering thickness affected significantly the emergence rate [WTBX](P<0.05),[WTBZ] the emergence rate was increased with the increase of soilcovering thickness and reached its maximum value when the soilcovering thickness was increased to 10 cm. The effect of soilcovering thickness on the seedling growth was not significant; ② The effect of sowing time on the emergence rate was significant when the soilcovering thickness was 0-3 cm [WTBX](P<0.05).[WTBZ] The emergence rate that the sowing time was on November 1 was higher than that on December 10 because of the temperature difference, and the emergence rates that the sowing time was on these two days were (11.9±1.2)%-(53.2±20.7)% and (1.5 %±0.8)%-(42.0±0.7)% respectively; the effect of sowing time on the seedling growth was not significant but the leaf area [WTBX](P<0.05).[WTBZ] Therefore, it could be concluded that soilcovering was advantageous for improving the emergence rate of [WTBX]Q. wutaishanica,[WTBZ] but its effect on the seedling growth was not significant.
