摘要
根肿病严重威胁着大白菜的产量和品质,并对其他十字花科植物也有较大的潜在威胁。本试验从育苗、栽培、田间管理等环节对大白菜根肿病进行综合防治技术研究,包括在育苗基质中加入生防菌、不同药剂对育苗基质和定植田土壤进行消毒处理等。结果表明:育苗基质中加入大白菜内生混合菌株Bacillus subtilis和Paenibacillus azotofixans(基质中平均每株大白菜施用量1×108CFU)并结合50%氟啶胺悬浮剂(OF)消毒定植田土壤(使用量4500mL·hm-2)对大白菜根肿病的综合防治效果最好,防效达85%以上。
Clubroot severely influences the yield and quality of Chinese cabbage〔Brassica campestris L.ssp.pekinensis(Lour)Olsson〕.In addition,the pathogen of clubroot,may infect other plants of the family Cruciferae.The experiment studied the integrated technology for controlling Chinese cabbage from seedling,cultivation,field management etc.The integrated technology includes adding biocontrol bacteria in substrate,different medicament disinfection treatments on nursery substrate and field planting soil.The results showed that adding endophytic Bacillus subtilis and Paenibacillus azotofixans with 1×108 CFU per seedling and 50% fluazinam OF to disinfect the field soil(4 500 mL·hm-2)in nursery substrate for controlling Chinese cabbage clubroot.The relative control effects were more than 85%.
