摘要
对西双版纳景洪市景哈试验点团花与马占相思混交林4年生的统计分析证实,团花纯林树高年均生长量为2.73 m,是混交林树高的1.26倍,纯林胸径年生长量为3.24 cm,是混交林胸径的1.44倍。混交林伴生树种马占相思对团花树高和胸径的生长影响很大。
A statistic analysis on 4 years Anthocephalus chinensis. ＋ Acacia magnum mixed plantation trial was presented in the paper. The results showed that the annual mean growth on height of Anthocephalus chinensis pure stand was 2.73 m, 1.26 times of that of the mixed plantation ; and the annual mean growth on DBH of Anthocephalus chinensis pure stand was 3. 24 cm, 1.44 times of that of the mixed plantation. The fact suggested Anthocephalus chinensis was affected remarkably by Acacia magnum in the mixed plantation on both height growth and DBH growth.
