秃杉中幼林施肥试验

The Fertilizing Experiments on the Middle-aged and Young Forests of Taiwania flousiana Gaussen

在云南省腾冲县对11~14年生的秃杉人工林开展大量元素N、P、K和微量元素Zn、Mn、B、Cu等不同肥料的连续施肥试验。连续4 a的试验结果表明,施肥对秃杉树高、胸径、单株材积生长量的影响差异均不显著,说明秃杉在中幼林期不必施肥。研究结果可为秃杉人工林经营提供参考。

We applied fertilizers containning elements of N,P,K and trace elements of Zn,Mn,B,Cu on 11~14 year saplings of Taiwania flousiana Gaussen by successive 4 years.It demonstated that there was no statistical significance in performance of tree height,DBH and growth of volume of single trees.This suggests that in management of the sapplings of Taiwania flousiana Gaussen,applying fertilization is not necessary.
