福建龙岩米老排林分生长效果分析及优树选择
|
摘要
应用随机抽样法对福建省龙岩不同林龄米老排现有林分进行调查,结果表明:影响米老排生长的关键因子是立地类型;不同林龄米老排树高年均生长量为0.8~1.2 m,胸径年均生长量为0.7~1.6 cm,其树高、胸径、单株材积总生长量随着年龄增加而增加,年均生长量均超过米老排人工林自然生长量,呈现生长迅速、适应性广、抗性强、萌芽力强、树干通直、成材早等特性;米老排是马尾松近自然改培针阔混交首选阔叶树种;以生长性状为指标精选出米老排优树20株。
The existing stand of Mytilaria laosensis at different ages was investigated by using random sampling methodin Longyan County of Fujian Province. Result shows that the key factors influencing the growth of Mytilaria laosensis are site types; the average annual growth of Mytilaria laosensis at different tree ages is 0. 8-1. 2 m,the average annual growth of DBH is 0. 7-1. 6 cm. The total plant growth of tree height,DBH and individual timber volume increase with stand age,and the average annual growth exceeds the natural growth of Mytilaria laosensis plantation,which shows rapid growth,wide adaptability,strong resistance,strong sprouting force,trunk straightening,early fruiting and other characteristics; Mytilaria laosensis is the first choice of broad-leaved tree species for Pinus massoniana to transform natural conifers and broad-leaved mixed conifers; twenty Mytilaria laosensis were selected with growth traits as indicators with excellent trees.
