为花榈木苗木的科学培育管理和培育优质壮苗提供理论依据，利用 Logistic方程拟合方法，对花榈木1年生实生苗木的苗高和地径的年生长发育节律进行了研究。结果表明：花榈木苗木的年生长量呈明显的慢－快－慢－快－慢”的生长发育节律。花榈木生长可划分为出苗期、生长初期、速生期和生长后期4个阶段，出苗期为5月上旬至6月上旬，持续时间长；生长初期为6月中旬，持续时间短，仅10 d；速生期为6月中下旬至8月中下旬，持续时间长，生长量最大，占整个苗高生长量的56．46％、地径生长量的54．69％；地径比苗高提前10 d 进入速生期，持续时间比苗高短22 d，苗高在8月中下旬还有较大生长生，地径在8月中旬提前进入生长后期，苗高持续生长一段时间后在8月下旬进入生长后期。

The annual growth rhythm of height and ground diameter of O.henryi seedlings with one-year old was studied by Logistic fitted equation to provide the theoretical basis for scientific cultivation management of O.henryi seedlings and nursing quality and strong O.henryi seedlings.The results showed that the annual increment of O.henryi seedlings presents the growth rhythm of slow-fast-slow-fast-slow. Growth of O.henryi seedlings can be divided into emergence stage (from the first ten-day period of May to the first ten-day period of June),early growth stage (during the middle ten-day period of June),fast-growing stage (from the mid-to-late ten-day period of June to the mid-to-late ten-day period of August)and late growth stage (from the late ten-day period of August).The growth of ground diameter enters the fast-growing stage 10d early than growth of seedling height,and the duration shortens 22d compared with duration of height growth.The increment of height and ground diameter accounts for 56.46% and 54.69%of total growth amount respectively.The growth of ground diameter and height enters the late growth stage in the middle ten-day period of August and the late ten-day period of August separately.
