摘要
根据单株旱柳解析木资料,建立了以时间为自变量的树木生长量函数,通过对函数的求导等数学运算,求出树木生长的成熟龄。结果表明:旱柳的期望成熟龄为21a。
According to data of analytic trees for individual Salix matsudana,the function of tree growth was established by taking time as independent variables.Through derivation and other mathematics on function,the maturity age of tree growth was calculated.Result shows that:expected maturity age of Salix matsudanais 21 a.
