摘要
This paper studied that the significant difference exists among the ten provenances of 9-year-old Fraxinusmandshurica stand. The rule of geographic variation is that dual continuous changes with longitude and latitude, and theprovenance in the southwest range grows rapidlv. There are positive signilicant correlation when the tree growth is influencedby≥ 10℃ accumulated temperature. duration of sunshine and annual precipitation So it is suggested that Lushuihe and Maoershan provenances should be emploved first in Maocrshan Forest Farm and its neighborhoods.
