摘　　要：采用大田对比试验,以中烟100为材料,研究了Agri-star松土促根剂对烤烟生长发育、主要病害及经济性状的影响。结果表明,与不施松土促根剂相比,施用Agri-star松土促根剂处理烟株的农艺性状均有提高,移栽后45 d,株高增加4.4 cm,茎围增加0.26 cm,叶片数增加0.8片,叶面积增加184.1 cm2,其中叶面积提高最明显;降低了烟草花叶病和气候斑点病的发病率,二者分别下降14.3、7.5个百分点,提高了烟株的抗病能力;增加了烟株根、茎、叶干物质质量和根系体积,促进了根系发育;使得烟叶的经济性状有了明显提高。In this study, a specific Agri-star soil conditioner was tested to investigate its effect on the growth,main diseases and economic traits of tobacco using the variety Zhongyan 100 as tested material. The results indicated that, compared with the conventional fertilization, treatment with Agri-star soil conditioner improved the tobacco agronomic traits, which increased the plant height, stem girth, leaf number and leaf area by 4. 4 cm,0. 26 cm,0. 8 and 184. 4 cm2 at 45 d after transplanted,respectively, with the leaf area increase being the most obvious. The rate of tobacco mosaic and weather speck decreased 14. 3 percentage points and 7. 5 percentage points,respectively. Agri-star soil conditioner could enhance the growth of root, stem, leaf biomass of tobacco significantly, and also improved the economic traits.
