深栽造林技术自从1980年引入我国以来,已经有了很大的发展。从较湿润的地区发展到干旱地区、甚至荒漠地区,从单一树种(杨树)发展到多树种深栽,从机械钻孔发展到机械钻孔与人工深挖相结合,宜钻则钻,宜挖则挖。从1981年起,中国林科院林研所先后在北京、山东、宁夏、甘肃、内蒙古等地推广深栽造林技术,较系统地研究了深栽树木水分代谢的特点,证明了深栽树木的吸水作用与其水分优势。地处干旱荒漠地带的酒泉地
Since the introduction of deep forest cultivation technology into our country in 1980, great progress has been made. From more humid areas to arid areas and even desert areas, the development from single tree species (poplar) to multi-species deep planting, from mechanical drilling to mechanical drilling combined with manual digging, drilling should be drilled, should Dig digging. Since 1981, Lin Institute of Chinese Academy of Forestry has successively promoted deep planting techniques in Beijing, Shandong, Ningxia, Gansu and Inner Mongolia. The characteristics of water metabolism in deep planting trees have been systematically studied, and it has been proved that deep planting trees Water absorption and its water advantage. Located in arid desert areas Jiuquan
