摘要
山苍子（Litsea cubeba（Lour）Pers.）是我国重要的传统林果类经济树种,具有生长快,结实早、耐瘠薄,易繁殖的特点,加强其树种良种选择和壮苗培育、种质发掘具有十分重要的意义。山苍子又名木姜子、山胡椒、毕澄茄、山鸡椒,为樟科木姜子属的珍贵芳香油料小乔木。在全世界约有250余种,主要分布于亚洲东部、大洋洲和太平洋诸岛。我国约有46种,广泛分布于长江以南贵州、广西、福建等省（区）,以野生资源为主,在食品、医药、香料等方面用途广泛,为我国主要的林副特产之一。
The annual growth rhythm of Litsea cubeba seedling was studied.The average thousand-grain weight of L.cubeba was 35 g,and the germination rate was higher than 70%.The results of cluster analysis showed that,the growth period could be divided into 4 stages,i.e.the stage of seedling emergence（from March 2 to March 17）,the initial stage of growth（from March 18 to May 31）,the vigorous growth stage（from June 11 to August 29） and the late growth stage（from August 30 to December 27）.The height and diameter of one-year-old seedling were fit with logistic curve law,and the growth process followed a ＂slow-fast-slow＂curve.The equation of average daily growth showed that the fastest growth appeared in July which had the highest monthly average temperature.This conclusion provided a reference for the seedling stage management of L.cubeba forest.The authors recommend vigorously developing L.cubeba forest in the mountainous area of Guizhou Province,and providing scientific and technological support to the forest tenure reform.
