基肥对依兰香造林成活率及幼林期生长影响

The afforestation survival rate and comparison growth of Cananga odorata using different kinds of based fertilizer

依兰香(Cananga odorata)也称为依兰依兰,是一种热带珍贵木本香料树种,枝繁叶茂、花形雅致、香气独特浓郁,具有重要的生态景观及药用价值。它原产东南亚的印度尼西亚和菲律宾等地,现热带地区具有广泛分布。采用单因素随机区组设计,对比了不同基肥对依兰香造林成活率及树高胸径生长的影响。结果表明:施用基肥可以适当提高依兰香造林成活率,其中以处理2(每株施1600g乐岛有机肥)效果最好,造林成活率达94.81%,显著高于对照。施用不同的基肥,对依兰香的生长均有不同程度的促进。各处理间对依兰香树高、胸径影响大小的顺序均为处理2(1600g乐岛有机肥)>处理1(800g乐岛有机肥)>处理4(250g钙镁磷肥)>处理3(125g钙镁磷肥)>处理5(空白对照)。

Cananga odorata, also known as ylang-ylang, is a type of tree that thrives in many tropical environ-ments. It is prized for its fragrant flowers, which has important ecological landscape and medicinal value. This plant is native to Indonesia and the Philippines, but is now present in many different tropical areas. A single factor randomized block design was adopted to study on the survival rate of afforestation and the influences of growth of Cananga odorata. The results showed that： Applying basal can improve appropriately ylang af-forestation survival rate, of which deal with 2 （per 1600 g LeDao organic fertilizer rates） effect is best, af-forestation survival rate was 94.81%, significantly higher than control. Application of different basal, all have different degrees of influence on the growth of ylang incense. Between different processing of yilan incense tree height, diameter at breast height influence the size of the order are all treatment 2 LeDao organic fertilizer （1600 g）＆gt;1 LeDao organic fertilizer （800 g）＆gt;4 calcium-magnesia phosphate fertilizer （250 g） ＆gt;processing treatment 3 calcium-magnesia phosphate fertilizer （125 g）＆gt;5 （ck）.
