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20d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。
To compare nursery effect between open field and greenhouse sowing seeds ,the effect of different so-wing 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 Catalpaovata 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 green-house .
