容器苗造林与裸根苗造林比较,具有根系完整、缓苗时间短、造林成活率高、延长造林季节等优点。但在常规栽植覆土踏实过程中,存在着影响造林成活率的两个重要技术问题。挤压不实、不均,造林苗木的土坨与土壤之间形成缝隙,如遇降水量少的年份,造林苗木就会因失水而干枯。挤压用力过大,造成伤根,造林成活率将会降低。为了解决上述栽植过程中的问题,笔者摸索着制作了容器苗植苗挤实铲。制作技术。容器苗植苗挤实铲由铲面、连杆、手柄三部分组
Container seedling afforestation and bare root seedling afforestation compared with a complete root system, Huanmiao time is short, high afforestation survival rate, extending the advantages of afforestation season. However, there are two important technical problems that affect the survival rate of afforestation in the practical planting and soil-covering process. Squeeze the false, uneven, reforestation soil seed lumps and the formation of gaps between the soil, in case of precipitation less years, reforestation seedlings will dry due to dehydration. Squeeze too much force, resulting in injury root, afforestation survival rate will be reduced. In order to solve the above problems in the planting process, I grope for the production of container seedling seedling shovel shovel. Production technology. Container seedling seedling shovel squeezed by the shovel surface, connecting rod, handle the three groups
