鼎湖山自然保护区森林茂密,郁郁葱葱。这里有南亚热带季风常绿阔叶林及大片的针阔叶混交林。在保护区外还有不少的马尾松、大叶桉林和灌木草丛植被。为了保持生态平衡,扩大森林面积,在六十年代初期和近几年来,我们曾用育苗造林的方法对一些马尾松林进行人工改造,已取得显著效果。但育苗工作比较繁锁,花工多,为了加快荒山绿化和低劣林分的改造速度,我们在今年春季进行了荷木和(木黎)蒴种子直播造林试验。现将试验的情况作一介绍。一、试验地概况试验地位于树木园实验大楼后山的中上 Dinghushan Nature Reserve lush forest, lush. Here are the southern subtropical monsoon evergreen broad-leaved forest and large coniferous and broad-leaved mixed forest. Outside the protected area there are plenty of Pinus massoniana, Eucalyptus grandis and shrub vegetation. In order to maintain the ecological balance and expand the area of ​​forest, we have made remarkable improvements in some man-made pine forests by means of nursery and afforestation in the early 1960s and in recent years. However, the nursery work is rather complicated and laborious. In order to speed up the afforestation of the barren hills and the transformation speed of the poor stands, we carried out the direct seeding experiments of the seeds of Shijimu and Muli in this spring. Now the trial of the situation for an introduction. First, the test site Overview Experimental site in the Arboretum experimental building in the mountains
