随着大规模的植树造林运动的深入,全国待绿化的地区多为土壤瘠薄、气候干旱的阳坡、半阳坡石质山区,造林难度大,用传统的裸根苗造林往往要反复补植多次,保存率还很难达到国家的验收标准。这样既浪费人力、物力、财力,又挫伤群众造林积极性,影响绿化进程。为解决这一老大难问题,近几年许多省区都不约而同地把目光转向了容器苗造林。
With the deepening of large-scale tree planting and afforestation campaigns, most of the areas to be afforested in the country are mostly barren and arid climatic slopes and stony mountainous areas with semi-sunny slopes. Afforestation is often difficult. Traditional bare root seedling afforestation is often repeated Times, the preservation rate is still difficult to meet the national acceptance criteria. This will not only waste manpower, material resources and financial resources, but also dampen the enthusiasm of the masses for afforestation and affect the greening process. In order to solve this long-standing problem, in recent years many provinces and autonomous regions have all turned their attention to the container seedling afforestation.
