- 摘要:
- 为比较梓树露地播种育苗与大棚播种育苗的育苗效果，研究了不同播种方式对梓树播种后种子破土时间、出苗时间、出苗率以及梓树植株性状的影响。结果表明：与露地播种育苗相比，大棚播种育苗出苗时间可提前20 d左右，出苗率高出7%，幼苗植株高度高出57.2%，基茎高出35.7%，叶片数高出75.8%，而且大棚内梓树幼苗叶片较大。
- Abstract:
- To compare nursery effect between open field and greenhouse sowing seeds,the effect of different sowing methods on ground-breaking time，emergence time，emergence rate，plant character of Catalpa ovata D.Don were studied.The results showed that:compared with open field seedling，emergence time of greenhouse seedlings was shortened 20 days，emergence rate of Catalpa ovata D.Don increased 7%，plant height increased 57.2%，basal stem increased 35.7% and leaf number increased 75.8%,seedling leaves were larger in greenhouse.
