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.
