摘要:

对桤木无性系植株不同处理对嫩枝芽数的影响进行研究。结果表明:不同无性系的嫩枝芽数主要是由栽植密度和无性系特性决定的,并且同苗高、修枝强度和施肥有密切的关系。对于建立桤木无性系采穗圃来说,适宜的栽植密度和苗高应该分别是1m×2m和90cm,修枝强度应该采用轻度或中度短截,同时需要加强施肥管理。以上措施不仅能够增加嫩枝芽数,而且可以增大树冠,促进树木生长,确保桤木无性系采穗圃的高产稳产。

Abstract:

Effect of different treatments of Alnus cremastogyne clones on Buds of Browse was studied. The results showed that the total buds of browse of different clones were mainly determined to theirs age, planting density and characteristics, and had close relationship to theirs seedling height, pruning density and fertilization. For establishing cutting orchard of A.cremastogyne clones, the suitable planting intensity and seedling height should be 1 m×2 m and 90 cm, respectively. The pruning intensity should be light or medium-level short cutting, and fertilization management should be strengthened too. Such methods mentioned above would not only increase the total buds of browse, also enlarge theirs tree crowns and boost tree growth status to guarantee the high and stable yield of the cutting orchard of A. cremastogyne clones.
