摘要
通过设计N、P、K、NP、NK、KP、NPK和CK肥等8个施肥处理,重复3次,进行不同肥料对西南桦幼林树高和胸径生长影响试验,通过单因素方差分析和多种比较结果表明:施肥能促进幼林的生长和发育,以NP肥促进作用最大;不同施肥处理高生长和胸径生长差异显著;幼树生长基本趋势是随林龄增长生长逐渐加快;西南桦生长与当地气候关系密切。
The experiments were conducted to study the impact of eight times of treatments by applying fertilizer with repetition of 3 times on height and DBH growth of Betula alnoides sapling. The result showed that applying fertilizer could promote the growth of Betula alnoides, in which NP fertilizer was the most; and the differences of height and DBH growth were tremendous with different treatments; and the tendency of the growth were speeded up gradually with growing up ; and the growth of Betula alnoides related with the local climate.
