“三北”地区风沙干旱严重地影响造林成活率和林木生长，影响防护林体系建设。解决抗旱造林是该地区林业建设当务之急。修剪侧枝可提高造林成活率９％左右；浸根可提高造林成活率９％～１１％；深栽可节约用水，促进幼林生长。１９７８～１９８７年间，辽西地区，采用此技术营造的近３３３３３３ｈｍ２杨树速生丰产林，成活率高达９８％，一次成林，节省了大量人力物力财力。 The wind and sand droughts in the “Three Norths” region seriously affect the survival rate of afforestation and tree growth, and affect the construction of shelterbelt system. Resolving drought and afforestation is the priority of forestry construction in this area. Trimming the side branches can increase the survival rate of afforestation about 9%; soaking roots can increase the survival rate of afforestation 9% ~ 11%; deep planting can save water and promote young forest growth. From 1978 to 1987, nearly 333333hm2 poplar fast-growing and high-yield forest with this technique was built in western Liaoning. The survival rate was as high as 98%. Once forestation was completed, a large amount of manpower, material and financial resources were saved.
