用扦插造林是建立杉木无性系种子园,进行无性系当代鉴定和繁殖、推广优良无性系的方法之一。但杉木老枝扦插生根困难,为此,一九七四年我们进行促进杉木老枝扦插生根的试验,获得初步成效,其中用吲哚丁酸1000～2000PPM浓度的溶液浸泡处理的生根率达65～80％。现将试验结果初报如下:

Cutting with afforestation is the establishment of Chinese fir clonal seed orchard, clonal identification and reproduction of the contemporary promotion of excellent clones method. However, the old cuttings of Chinese fir were difficult to root. Therefore, in 1974, we carried out the experiment of promoting the root cutting of old cuttings of Chinese fir and achieved the initial results. The rooting rate of soaking with the solution of 1000-2000 PPM of indole butyric acid reached 65 ~ 80%. The first test results are reported as follows:
