摘　　要：中山杉(Taxodium hybrid'zhongshanshan')是落羽杉属种间杂交良种,有突出的经济价值、生态价值和美学价值。通过引进邻近地区江苏等地中山杉良株在鲁南地区连续多年观察物候期,开展异地栽植试验研究的结果表明:春季解冻后,移栽时间越早成活率越高,2月20日前后是鲁南地区最适宜时间。在生根粉浓度相同的条件下,沙壤地成活率(95.67%)高于粘壤地和棕壤地成活率(92.67%和87.00%);沙壤地最佳生根粉浓度为45μg/kg,粘壤地最佳生根粉浓度为75μg/kg。Taxodium hybrid'zhongshanshan'is an excellent interspecific hybrid species of the genus Taxodium,which has high outstanding economic,ecological,and aesthetic value.By introducing high-quality Chinese fir plants from neighboring regions such as Jiangsu to observe phenological periods for many consecutive years in the southern region of Shandong,we conducted experiments on off-site planting.The experimental results show that after thawing in spring,the earlier the transplanting time,the higher the survival rate.The most suitable time for the southern region of Shandong is around February 20th;.Under the same concentration of rooting powder,the survival rate of sandy soil(95.67%)is higher than that of clay soil(92.67%and 87.00%);The optimal concentration of rooting powder in sandy soil is 45ug/kg,and the optimal concentration of rooting powder in clay soil is 75ug/kg.
