摘　　要：[目的]找出绿色植物生长调节剂GGR6在杉木育苗上应用的最佳浓度。[方法]利用GGR6对杉木种子进行浸种处理,研究3种不同浓度处理对杉种发芽率和杉苗生长的影响。[结果]杉木播种育苗,采用GGR620 mg/L浓度浸种处理,对提高种子发芽率效果更好,能提高种子发芽率2.9个百分点;采用30 mg/L浓度浸种处理,对促进苗木生长效果更好,与对照相比,苗高增长3.8%,地径增长15.8%。[结论]使用绿色植物生长调节剂GGR6,可以提高杉木的种子发芽率、苗木成活率,并促进苗木生长;对杉木浸种育苗,以30 mg/L浓度为好。[Objective]The aim was to find out the optimum concentration of green plant growth regulator GGR6 in the application of Chinese fir seedling cultivation.[Method]GGR6 was used to soak Chinese fir seeds,and the effects of three different concentrations on the germination rate of Chinese fir seeds and the growth of Chinese fir seedlings were studied.[Result]GGR620 mg/L concentration soaking treatment had better effect on improving seed germination rate,which could increase seed germination rate by 2.9 percentage points.Seed soaking treatment with 30 mg/L concentration had better effect on promoting seedling growth.Compared with the control,seedling height increased by 3.8%and ground diameter increased by 15.8%.[Conclusion]The use of green plant growth regulator GGR6 can improve the seed germination rate and seedling survival rate of Chinese fir,and promote the growth of seedlings.The concentration of 30 mg/L is better for Chinese fir seedling.
