1982年6月,日本新县林业公司在日本柳杉造林试验地上采用斜栽造林,在减轻大雪危害方面取得了成效。他们把斜栽造林作为一项指导性技术被普遍采用。斜栽造林之所以减轻大雪危害,主要是用这种方法栽植的苗木倒伏角(沿斜坡面倒伏的角度)比普通栽植法小,可以防止根系损伤,即使在平坦地也能防止树根折损。另外,作为深栽的变形,使埋干部分变长,较多地生出不定根(二次根),防止根悬和冻拔,促进了树高生长。斜栽造林工序:(1)清除栽植点中70厘米以内的落叶、杂草以及地被物。(2)栽植穴挖掘的大小,以使根系能很舒展放入为准,深度以使幼树下端2～3枝能放入为度。切忌过浅,免使根部露出地表。(3)挖上来的土,堆在下坡方向一 June 1982, Japan’s Shinsengu forestry companies in Japan Cryptomeria plantation test ground afforestation with oblique, in reducing the damage caused by heavy snow has achieved results. They have adopted oblique planting as a guiding technique. The reason why oblique planting is to reduce snow damage is mainly that the seedling lodging angle (the angle of lodging along the slope) planted by this method is smaller than ordinary planting method to prevent root damage and prevent the root damage even even on the flat ground . In addition, as the deformation of deep planting, the burying part is lengthened, adventitious roots (secondary roots) are generated more, root hanging and freezing are prevented, and tree height growth is promoted. Oblique planting plantation process: (1) clear the planting points within 70 cm of the leaves, weeds and ground cover. (2) planting hole excavation size, so that the roots can be very well into the depth, so that the bottom of the young tree 2 to 3 can be put into degrees. Avoid too light, so that the roots exposed surface. (3) dig up the soil, heap in the direction of a downhill
