不同播种方法对连翘种子出苗率影响的试验研究

为了提高连翘播种出苗率，发展连翘产业。通过不同处理方法播种对连翘种子出苗率影响的试验研究分析。结果表明，春播以惊蛰后播出苗率高，秋播以9月下旬播出苗率高；连翘果实9~10月成熟，以10月中旬充分成熟的种子播后出苗率高；晒干和阴干的种子以阴干种子播后出苗率高；成熟合格的种子播后以砂壤土出苗率高；在播前冬季种子沙藏处理后播出苗率高；种子用萘乙酸（NAA）200 μg/g溶液催芽处理后播出苗率高。对连翘种子出苗率的试验研究为商州区连翘播种育苗提供科学依据。

Effects of Different Sowing Methods on Germination Rate of Forsythia Suspensa

To enhance the seeding rate of Forsythia suspensa seeds and promote the development of the Forsythia suspensa industry, an experiment was conducted to investigate effects of different treatments on the seed emergence rate. The results showed that sowing after Jingzhe in spring or late September for autumn sowing led to higher emergence rate; the seed emergence rate was higher when the fully mature seeds were harvested in mid-October; the seed emergence rate was higher when the air-dried seeds were used compared to sun-dried seeds; the seed emergence rate was higher when using sandy loam for sowing with mature and qualified seeds; the seed emergence rate was higher when using sand storage for winter seed before sowing; and the seed emergence rate was higher when using a 200 μg/g solution of naphthaleneacetic acid (NAA) for seed germination treatment before sowing. This experiment provides a scientific foundation for Forsythia suspensa seedling-raising in Shangzhou area.
