| 摘 要： | 在油松育苗中应用不同浓度的双吉尔-GGR6,探索其对油松出苗及幼苗生长的影响。结果表明,使用20mg/L的双吉尔-GGR6对油松幼苗粗生长的促进效果优于100mg/L喷施宝,而对幼苗高生长的作用与100mg/L喷施宝和空白对照无明显差异;用40mg/L的双吉尔-GGR6对油松种子出苗有一定的抑制作用;用GGR6和喷施宝处理苗木后,幼苗猝倒病的发生率均有明显降低。建议在油松育苗生产中使用浓度为20mg/L的双吉尔-GGR6。

| Abstract: | Using different concentrations of GGR6 in growing seedlings of Pinus tabulaeformis Carr.to explore effect of GGR6 on the growth of seedlings and on lifting.The results showed that GGR6 at 20 (mg/L) is more effective than the PSB at 100 mg/L to promote germination of seeds,lifting and the growth of diameter,but has no marked difference with PSB at 100 mg/L and CK to promote growth of height.GGR6 at 40 mg/L has inhibition to seedling.The resistance to disease of seedlings increases after using GGR and PSB.So the suggestion is given that GGR6 at 20 mg/L can be used in the production of Pinus tabulaeformis Carr.seedlings. |
