AbstractTo investigate the growth rhythms of two-year-old Pinus huangshanensis，Pinusmassoniana and hybrid pine in Jiuhua Mountain area，this study adopted a randomized block design and conducted sowing and seedling cultivation experiments on these 3 tree species groups in the same nursery plot.The dynamic changes of seedling height were continuouslyobservedand recorded.The results showed thatthe total growth volumeof oneyear-old seedlings of the 3 pine species accounted for 30.62% ，29.98 % and 21.14% of the total growth volume in two years，respectively.The growthrhythms of all3species were characterized byarelativelysmall growth amount inthe firstyear，andasignificantly higher growth amount inthe second year compared to thefirst year.3rapid growth periodsoccurredduring theseedling stage forall 3species，and theoverall growth processof plant heightfollowed the“S”curve characteristics.There were differences inthe total growth volume among the3species，andthe total growth volume of seedling height from largest to smallest was Pinus massoniana > Pinus hwangshanensis > hybrid pine.This study providesareference for thecultivation of artificial forest seedlingsof pine，seedling management during the seedling stage，and the selection of high quality seedlings.

黄山松（Pinushwangshanensis）、马尾松（Pinusmassoniana）是重要的造林树种，在九华山的部分海拔区域呈现马尾松和黄山松分布重叠的现象，在分布重叠区，二者存在天然杂交现象并形成天然的杂交种（以下称为杂交松）。（剩余3933字）
