Study on Introduction and Transplantation of Taxodium hybrid'zhongshanshan'in Southern Shandong Region
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.
