| 摘 要： | 对铁核桃、黑核桃生长发育规律及耐涝性进行了分析,结果表明:(1)与铁核桃相比,黑核桃萌发期偏迟,但新稍封顶早、落叶早。(2)铁核桃在整个观测期生长迅速,5—6月生长速度最快,而黑核桃主要生长期集中在5—7月,7月中旬以后生长量偏小;(3)极端高温天气、水分不足是黑核桃在引种区生长较差的主要因素;(4)黑核桃耐涝性强于铁核桃。

| Abstract: | The growth regularity and waterlogging resistance were analyzed for Juglans sigillata and black walnut ( J. nigra ).The results showed that (1) leaves of black walnut germinated later than of those J. sigillata ,but new shoots would stopped growing and wilting early.(2) J. sigillata grew fast,especially in May and June, and black walnut grew up mainly in May ,June and July;(3) Extremely high temperature and water shortage were the main influencing factors of black walnut s poor growth;(4)Black walnut was more resistant to waterlogging than J. sigillata . |
