摘  要：
文章以蒙古栎种子为材料,研究不同播种时期对蒙古栎出苗、生长的影响。2015年5月初开始调查出苗率、苗高、地茎、地上部和地下部生物量。结果表明:在9-10月播种的出苗率以早期(Z1)的最高,大于80%,出苗第35天达到90.2%。其他时期播种的蒙古栎出苗率也均在60%以上。早期播种的苗木苗高差异不大,但是Z1处理下较大,为15.9 cm。Z1和Z2处理地径较大,分别为4.83和4.95 mm。早期播种的蒙古栎生物量也较大,明显高于其他播种时期。所以,蒙古栎在秋播育苗时适宜早播。

摘  要：
Mongolian oak seeds were selected as the research materials to study the effects of sowing time on seedling emergence and growth. The results show that seeds sowed from September to October have the highest rate of seedling emergence in the early stage( Z1), greater than80%, and the rate is 90.2% on the 35 th day. The germination rate of Mongolian oak in other period was also more than 60%. No big difference among the heights of the early seedling, but it can be 15.9 cm after Z1 treatment with bigger difference. The diameters of Z1 and Z2 treatments were larger, which were 4.83 and 4.95 mm respectively. The biomass of Mongolia oak was also larger in early sowing, which was significantly higher than in other sowing times. So early sowing is more suitable for Mongolian oaks during the autumn sowing.
