摘要
试验对 5.5年生尾叶桉实生林砍伐后 ,进行不同桩径的萌芽率、萌芽力、萌芽条的高和径生长调查。结果表明 ,桩径对萌发率的影响不显著 ,但对萌芽力有极显著的影响 ,在桩径 3～ 1 7cm的范围内 ,萌芽数量随桩径的增大而增加 ;萌芽条的高和径的生长也随桩径的增大而显著增大。
The effect of stump diameter on sprout regeneration in Eucalyptus urophylla was studied in Huadu site where E. urophylla plantation is 5.5a. The study is based on observations of different diameter of stumps. The results showed that sprouting percentage of the stumps did not change in diameter 3~17 cm. But sprouting number per stump increased with stump diameter. The height and diameter of sprouts increased with the increases in stump diameter.
