生物质材料在三七土传病害防治中的应用

Application of biomass materials in the control of Panax notoginseng soil borne diseases

  • 摘要: 三七是我国特有的名贵中药材,其生长受到土传病害的影响,甚至可导致三七绝收. 生物质材料在土壤病害微生物的防治中具有明显的应用价值,但目前较少应用于三七栽培. 研究选用高温烘焙碳化制成的生物材料A和发酵腐熟制成的生物材料B为供试材料,通过三七大棚原位栽培试验,探究了生物质材料相对于对照(CK)和三元复合肥处理(F)在一年期三七种苗出苗、根腐病防治及存苗率方面的作用;并通过土壤理化性质与酶活性分析,解释生物质材料防控土传病害的机理. 结果显示:未施用生物质材料的CK 组和F 处理组,在出苗后4 个月全部死亡;施用不同生物质材料的处理FA、FB、AB、FAB,对降低三七根腐病的危害、提高三七出苗率和中后期存苗率具有明显的作用,相对于CK和F处理差异均达极显著水平(P<0.01);施用生物质材料提高了酸性土壤的pH值及其蛋白酶、纤维素酶、脱氢酶、磷酸酶、脲酶活性(P<0.05),降低了土壤EC值及盐离子浓度影响(P<0.05);试验各处理对抑制三七根腐发病率的综合作用效果为FAB>AB>FA>FB>F>CK.

     

    Abstract: Panax notoginseng is a precious Chinese endemic herbal medicine. Its growth is affected by soil-borne diseases and can even lead to serious death. Biomass materials have obvious values in the prevention and treatment of soil diseases, but it has seldom been applied to the cultivation of P. notoginseng. In order to study the mechanism of prevention and control of soil-borne diseases by biomass material, biomaterial A made from high temperature baking and biomaterial B from fermentation were selected as experimental materials; In situ cultivation experiment was carried out to investigate the relative effect of biomass material on control (CK) and three elements compound fertilizer treatment (F); Seedling emergence, root rot prevention and survival rate of seedlings were recorded; Physical-chemical properties and enzymatic activities of the soil were also analyzed . The results showed that P. notoginseng in CK and F treatment groups all died in 4 months without biomass material treatment. FA, FB, AB and FAB treatments with different biomass materials had significant effects on reducing the harm of root rot on P. notoginseng, increasing the emergence rate and survival rate of P. notoginseng in the middle and late growing stages, and the effects had very significant difference with CK and F treatments (P < 0.01). Biomass material application increased the pH, cellulase, protease, dehydrogenase, phosphatase, urease activity (P <0.05), decreased the EC value and the concentration of salt ions in soil (P <0.05). The comprehensive evaluation of each treatment on the the control of P. notoginseng soil borne diseases was FAB> AB> FA> FB> F> CK. A new method for the biological control of soil-borne disease of P. notoginseng is provided in this study.
