解析1株天然林中148年生伯乐树倒木树干，表明其树高连年生长量在65年生时达到最大值，和树高年平均生长量曲线相交于80年生时；胸径连年生长量在70年生时达到最大值，与胸径年平均生长量相交于95~100年生时；而材积连年生长量的最大值出现在80年生时，与材积年平均生长量于135~140年间相交，此时可以认为是伯乐树的材积数量成熟年龄。

A 148-year-old fallen trunk of Bretschneidera sinensis was discovered incidentally in natural for-est and analyzed by researchers.The results showed that during the whole growth period of Bretschnei-dera sinensis ,the current annual increment of tree height reached the highest point at the age of 65,and intersected at the curve of average increment of height at the age of 80;the current annual increment of tree DBH reached the maximum value at the age of 70,and intersected at the curve of average increment of DBH at the age between 95 and 100.At the same time the current annual increment of timber volume reached the maximum value at the age of 80,and intersected at the curve of average increment of timber volume at the age between 135 and 140,and this period of time could be treated as the right time for the mature age of timber volume of Bretschneidera sinensis .
