天然苗移植造林,在大兴安岭林区是从1954年开始的。当时在缺少种苗的情况下,就采用了这一方法。并本着“间密补缺、就地疏开”的原则进行的。从1954年以来,淖尔材业局完成的150公顷移植任务中,经逐年调查,成活率达到了90％以上,有的已生长成林,即将郁闭,因此说这项作业是成功的。从苗木生长情况来看,1954年春季移植的到1958年的四年生长过程中,最高已达2.07米,根基茎3—5厘米,平均年生长为39.2厘米,特别在1958年一年高生长竟达79厘米。这一成功经验,在目前种苗不足的情况下,采用天然苗移植的方
Natural seedlings transplant afforestation, forest in Daxinganling started from 1954. At that time, in the absence of seedlings, this approach was adopted. And in line with “close secret fill, open in place” principle. Since 1954, after completing a 150-hectare transplanting mission by Seoul Bureau of Natural Materials, the annual survey shows that the survival rate has reached more than 90%. Some have grown into forests and will soon be closed. Therefore, this operation is said to be successful. From the seedling growth point of view, the 1954 spring transplant to 1958 four-year growth process, the highest reached 2.07 meters, root stems 3-5 cm, the average annual growth of 39.2 cm, especially in 1958 a year of high growth As much as 79 cm. This successful experience, in the current shortage of seedlings, the use of natural seedlings transplantation side
