摘要
平榛播种育苗试验结果表明：平榛种子处理应于11月末至12月初进行,浸种120h左右,水温为5~20℃为宜;采用沙藏层级法,层级时间120d以上;最佳播种时间为4月中下旬-5月初。播种方法为垄播或床播;播种密度为每公顷床播1 313kg、垄播1 125kg。
The experiment about the seedling raising of Corylus heterophylla Fisch were summarized.Seed were treated with water at the temperature 5℃-20℃for 12 hand was kept under stratification for 120 d.The best time for sowing was from April to early May.The seed was sowed in bed or ridged bed.The density sowed was 87.5kg in sowing bed or 75 kg in ridged bed per ha.
