造林前整地可以改善造林地环境条件,增强地力,提高造林成活率,促进林木生长。造林整地在春、夏、秋季均可进行,如在春季造林,先一年夏天就应整地。山地造林整地常用的方法有如下几种:水平带状整地.适宜在易受风蚀的沙荒和水蚀的缓坡地采用。带宽,带距应根据造林的行距和立地条件而定,一股为0.8~1米,深度为25厘米。带的方向应与等高线一致。水平阶整地.干旱的石质山地、黄土山地的缓坡和中等坡均适用。具体做法是沿等高线将坡面修筑成狭窄的台阶状台面。阶面水平或稍向内倾斜,有较小的反坡;阶面宽因地而异,石质山地为0.5~0.6米,土石山地及黄土地区1.5米;阶的外缘培修土埂;阶长为1~6米,视地形而定,
Site preparation before afforestation can improve afforestation land environmental conditions, enhance soil fertility, increase afforestation survival rate and promote forest growth. Afforestation in the spring, summer, autumn can be carried out, such as reforestation in the spring, the first summer should be the site. Common methods of afforestation in mountainous areas include the following: Horizontal banding, suitable for use in lowland and water-erosion gentle slopes susceptible to wind erosion. Belt width, belt spacing should be based on the line spacing and site conditions, depending on the afforestation, a stock of 0.8 to 1 m, a depth of 25 cm. The direction of the belt should be consistent with the contour line. Level leveling. Arid rocky, loess and gentle slopes are applicable. The concrete method is to construct the slope into a narrow step-shaped countertop along the contour line. Step or slightly inward slope, a smaller anti-slope; step width varies from place to place, stony hill 0.5 to 0.6 meters, rock and mountain and loess area 1.5 meters; The length of 1 to 6 meters, depending on the terrain,
