我省滇南、滇东南、滇西南地区,光照充足、热量丰富、水热条件好、土壤疏松、是开展飞播造林,发展林业的理想之地。但是,这些地区属高草地区,植被深密,给飞播造林带来困难。飞播造林对植被的要求是:一、要求植被的盖度与高度不能阻碍种子着地,二、要保证种子着地后有一定的阻挡和依托,能附着于地面,不会被雨水冲走,有利于扎根生长;三、种子发芽后有适当的植被荫蔽,但不能全部遮死。根据以上要求, Yunnan Province, southern Yunnan, southeast Yunnan, southwest Yunnan region, adequate light, rich in heat, good hydrothermal conditions, loose soil, is to carry out aerial seeding afforestation, the ideal place for the development of forestry. However, these areas are tall grassy areas with dense vegetation, which make it difficult for aerial seeding and afforestation. The requirements of aerial seeding afforestation are: First, it is required that the cover and height of the vegetation can not hinder the planting of the seeds. Second, to ensure that the seeds have a certain block and support after landing, they can be attached to the ground and will not be washed away by the rain, Rooted in growth; Third, the seeds germinate with appropriate vegetation shade, but not all cover up. Based on the above requirements,
