樟子松是沙地荒山绿化的主要造林树种。为了克服干旱对樟子松造林成活率的不利影响,科右后旗林业科技人员经过几年的造林试验实践,摸索出樟子松移床苗造林抗旱保活的科学方法——小坑垂直靠壁造林法。此法比原造林方法成活率提高25％。具体做法是:顺开好的沟进行挖坑,规格为坑宽6～10厘米,长20～25厘米,深16～25厘米(视根系长短而定)。栽植时,苗根靠住上部垂直的坑壁,然后覆土踩实。在土壤干旱的情况下,每穴
Pinus sylvestris var.mongolica is a major afforestation tree species in sandy desertification. In order to overcome the negative impact of drought on afforestation survival rate of Pinus sylvestris var. Mongolica, Forestry Science and Technology personnel of Section Youhouqiu worked out the practice of afforestation experiment for several years to find a scientific method of afforestation and seedling survival of Pinus sylvestris var. Mongolica - Wall Afforestation Law. This method improves the survival rate of the original afforestation method by 25%. The specific approach is: along a good ditch digging, specifications for the pit width of 6 to 10 cm, length 20 to 25 cm, 16 to 25 cm deep (depending on the length of the root system). When planting, seedling roots against the upper vertical pit wall, and then soil cover real step. In the case of soil drought, each hole
