摘　　要：通过对苦槠1年生实生苗苗高进行定期观测,采用Logistic方程拟合其苗高生长过程,并根据拟合方程划分苗木生长阶段。结果表明:苦槠1年生实生苗苗高年生长呈现“慢-快-慢”的规律;Logistic方程拟合效果显著,拟合曲线与实测曲线吻合度高,可进行苗高生长量的预测;同时可把苦槠苗木生长期划分为4个阶段,分别为:出苗期(1月28日—5月5日)、生长初期(5月6日—8月3日)、生长盛期(8月4日—10月16日)、生长后期(10月17日—12月20日),其中生长盛期的苗高生长量占总生长量的58.95%。The height of one-year-old seedlings of Castanopsis sclerophylla was observed regularly,and the growth process of seedling height was fitted by Logistic equation,and the growth stages of seedlings were divided according to the fitting equation.The results showed that the growth of one-year-old seedlings of Castanopsis sclerophylla showed a"slow-fast-slow"pattern.The logistic equation fitting effect was remarkable,the fitting curve was in good agreement with the measured curve,which could predict the growth of seedling height.At the same time,the growth period of Castanopsis sclerophylla seedlings could be divided into four stages,which were:seedling emergence stage(from January 28 to May 5),early growth stage(from May 6 to August 3),peak growth stage(from August 4 to October 16)and late growth stage(from October 17 to December 20),in which the seedling height growth in peak growth stage accounts for 58.95%of the total growth.
