窿缘桉是我局各场队现有桉树人工林的主要树种之一。该树比较速生,适应性强,能耐干旱瘠薄,萌芽力强。木材可做矿柱、建筑、农具等;桉叶能蒸桉油,提取栲胶等。但我局因台风常风频繁,土壤干旱瘦瘠,加之初期造林工作较粗放,没有严格选种,导致早期营造的窿缘桉出现比较严重的“慢弯倒”现象。为了改造这类林分,我们于1961年8月着手进行窿缘桉萌芽更新作业的试验研究,1963年总结初步成果后,在局属各场队扩大试验和推广。近十年来采用这种方法培育起来的萌芽林已达20万亩。生长普遍良好,初期长得快,干形直,基本上改变了原来“慢弯倒”现象。生产实践证明:萌芽更新作业法是改造三类桉树林比较迅速、经济、有效的方法。
Eucalyptus eucalyptus is one of the main species of Eucalyptus plantation existing in all the teams in our bureau. The tree is relatively fast, adaptable, able to drought barren, strong sprout. Wood pillars can be used, construction, farm tools, etc .; eucalyptus leaves Eucalyptus oil can be extracted, such as gum. However, due to the frequent typhoons and the arid barrenness of the soil and the extensive afforestation work in the early stage, there was no strict selection of species. As a result, the eroded eucalyptus in the early stage showed a rather serious phenomenon of “slow down”. In order to rebuild this kind of forest, we started the pilot study on the sprout regeneration of eucalyptus eucalyptus in August 1961. After the preliminary results were summarized in 1963, we expanded the test and promotion in the local team. In the past ten years, the sprout forest cultivated by this method has reached 200,000 mu. Growth is generally good, the initial grow faster, dry straight, basically changed the original “slow down” phenomenon. Production practice has proved that the sprouting and rejuvenation method is a quick, economical and effective way to transform three kinds of eucalyptus forests.
