摘　　要：以关苍术种子为试材,研究了不同温度条件下土壤基质、覆土厚度对关苍术出苗及秧苗质量的影响。结果表明:粉壤土中培育的关苍术种子出苗率和总存活率最高,分别达35.4%和71.9%;粘壤土虽然出土率不高,但总存活率可达69.8%;从关苍术出苗率、幼苗鲜重及总存活率来看,15℃时适宜覆土厚度为4cm,20℃时适宜覆土厚度为3cm;15℃条件下关苍术出苗时间为20d,比20℃晚8d,但出苗率和总存活率比20℃高。Taking the Atractylodes japonica Koidz. ex Kitam seeds as materials, the effect of soil matrix and overlying soil thickness on seed emergence and seedling quality under different temperature conditions were studied. The results showed that the emergence rate and the total survival rate of Atractylodes japonica in silty loam were the highest, which reached 35.4 % and 71.9 %. Although clay loam unearthed rate was not high,but its total survival rate could reach 69. 8%. From the emergence rate, seedling fresh weight and the total survival rate of Atractylodes japonica, the appropriate overlying soil thickness was 4 cm when the temperature was 15℃,and the appropriate covering thickness was 3 cm when the temperature was 20℃. The Atractylodes japonica emergence time was 20 d under 15℃ ,which was 8 d later than 20℃, but its germination rate and total survival rate were higher than 20℃.
