豫南杉木萌芽林生长规律的研究

Study on Growth of Common Chinaff Sprout Land in the South of Henan Province

摘要: 通过定点试验观测和典型抽样调查,研究了豫南杉木萌芽林生长发育规律.结果表明:杉木萌芽率随伐桩直径增加而下降,平均萌芽率可达90%以上;萌芽林生长与立地条件和原杉木生长情况有关,山区和丘陵立地条件为10立地指数以上;萌芽林生长前期快于实生林,但其树高、胸径、材积和生长过程与实生林相差不大.

Abstract: By fixing position observition and model sampling investigation the growing law of common chinaff was researched,the results showed that the sprouting rate of common chinaff declines with the lumbering diameter incersing,the average rate is over 90%.The well the site type is original plantation grows,the well the sprout land grows.The site type is over 10 site index.The sprout land grows faster than seedling stand in prophase,but there is hardly and differece from height,diameter,volume.
