在小山谷两岸和冲沟斜坡进行森林土壤改良,由于斜坡坡度、土壤片蚀程度、方位,冲刷等,营造人工幼林利用机械化整地,栽植和进行抚育是很困难的。在斜坡允许机械化工作的方法之一是梯田化。梯田化适应于推土机或犁。1966年在白俄罗斯作了斜坡梯田化的最初试验。这个试验在莫兹尔畦地进行。小山谷两岸的梯田化用筑梯田机T—4进行。梯田宽为2.4±0.3米。中心距随斜坡坡度而变化,一般为3—10米。梯田的第一线应从小山谷的坡顶起,梯田的中心必 Forest soil improvement takes place on both sides of the valley and on the slope of the gully. It is very difficult to create a young artificial forest for mechanized land preparation, planting and tending due to slope gradient, soil erosion, azimuth and erosion. One of the ways mechanizations are allowed on the slopes is terraced. Terraced adapt to a bulldozer or plow. In 1966 the first trial of terraced slope in Belarus was made. This test is carried out in Mozart. Terraces on both banks of the valley are constructed with T-4 terraces. Terrace width of 2.4 ± 0.3 meters. The center distance varies with the slope gradient, usually 3-10 meters. The first line of terraces should be from the top of the valley, the center of the terraces will be
