水杉是我国特有的珍贵树种,自1964年在四川省万县发现以来,世界许多国家竞相引种,做了大量地科学实验工作。1973年3月,我们从2年生水杉苗上截取1年生枝条,以不同浓度的生长素(吲哚丁酸、萘乙酸)作了浸泡处理试验,其方法如下: 插穗长10厘米,径粗0.3—0.5厘米,距下切口0.2—1.0厘米处留芽眼。应用吲哚丁酸、萘乙酸作高浓度快速处理,其处理浓度是500、1,000、2,000PPM,处理时间为5秒,每组20株,共6个处理组,对照组10株,计130株。每组将下切口浸于不同浓度的药液。1973年3月10日扦插于砂床上,砂层厚10厘米,扦插深
Metasequoia is endemic to China. Since its discovery in Wanxian County, Sichuan Province in 1964, many countries in the world have competed to introduce and have done a lot of scientific experiments. In March 1973, we cut 1-year-old branches from 2-year-old Metasequoia glyptostroboides and tested the soaking with different concentrations of auxin (indole butyric acid, naphthalene acetic acid) as follows: cuttings 10 cm in length and 0.3 in diameter -0.5 cm, 0.2-1.0 cm away from the next incision bud eyes. The indole butyric acid and naphthalene acetic acid were used for rapid treatment at a high concentration. The treatment concentrations were 500, 1,000, and 2,000 ppm, and the treatment time was 5 seconds. There were 20 plants in each group, with 6 treatment groups and 10 control plants . Each group will be immersed in the lower incision at different concentrations of liquid. March 10, 1973 cuttings in the sand bed, the sand thickness of 10 cm, cutting deep
