为了提高水杉扦插育苗的成活率,我们采用ABT生根粉浸泡水杉插穗,取得了较好的效果。从10—15年生的水杉树上,取1年生成熟枝中段,截成长10—15厘米的插穗,枝稍截成15—20厘米,用50ppm、100ppm的ABT生根粉溶液,分别浸泡12小时,清水为对照。4月6日扦插田间,共浇水6次,松土除草2次、不遮荫。插穗发芽后,分别为5月24日、7月12日、8月9日和9月22日调查苗木成活情
In order to improve the survival rate of Metasequoia cutting propagation, we use ABT rooting powder soaked in Metasequoia cuttings, and achieved good results. From 10-15 years old on the fir tree, take 1 year to generate the middle of ripening, cut 10-15 cm cuttings, branches slightly cut into 15-20 cm, with 50ppm, 100ppm ABT rooting powder solution, were soaked for 12 hours, Water as a control. April 6 cutting field, a total of 6 times watering, soil weeding 2 times, no shade. Cuttings sprouting, respectively, on May 24, July 12, August 9 and September 22 investigation of seedlings into the living
