Method for planting trees in high altitude regions

technical field [0001] The invention relates to a method for planting trees for greening, in particular to a method for planting trees in high-altitude areas. Background technique [0002] The survival rate of trees planted at high altitudes is extremely low, especially in areas above 4,500 meters above sea level, such as the Nagchu region. Over the years, although many attempts have been made in the Nagchu area, most of the trees died in the winter of the year they were planted, and the few that survived became shorter in the second year, and basically died in the third year. Although the "Research and Demonstration of Key Technologies for the Introduction and Cultivation of Plant Resources for Environmental Control on the Northern Tibetan Plateau" won the second prize of the Tibet Autonomous Region Science and Technology Award from 2008 to 2009, the research conclusion of this project is that the growth period of woody plants is short and the accumulated growth temperature...
