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,筛选出石灰岩山地原生树种——白枪杆的育苗、造林技术,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 experiment, we have screened the seedling and afforestation techniques of the native tree species of limestone mountainous area - white gun bar and popularized and popularized in the local rocky desertification control project.
