摘要
通过对羽叶丁香播种时间、环境、种子处理、播种深度进行对比试验研究,掌握了羽叶丁香播种繁育技术。研究结果表明:4月中下旬在日光节能温室采用经催芽处理的种子进行播种,播种深度为0.5～0.7cm时出苗率最高。
Through comparative experimental research on sowing time,environment,seed treatment and sowing depths of syringa pinnata,the sowing and breeding technology of syringa pinnata was mastered.The results showed that the germination rate was the highest when the seed depth was 0.5 ~ 0.7 cm when the seeds were sown in the solar energy-saving greenhouse in the middle and late April.
