云南东南部红河州的半干旱暖热石漠化地区,年降水量仅800mm左右,而蒸发量达降水量的3倍左右,是云南石漠化植被恢复较为困难的地区之一。经过多年的造林试验,探索出半干旱石漠化地区白刺花双月苗育苗造林技术,研发的育苗、造林技术将在当地的石漠化治理工程中得到大面积推广应用。
In the semi-arid warm-hot rocky desertification area in Honghe Prefecture, southeastern Yunnan, the annual precipitation is only about 800 mm, while the evaporation amount is about three times that of the precipitation. Therefore, it is one of the more difficult areas to recover the rocky desertification vegetation in Yunnan. After many years of afforestation experiments, we have explored the technology of birch seedling afforestation in semi-arid rocky desertification area. The research and development of nursery seedling and afforestation technology will be widely popularized and applied in the local rocky desertification control project.
