摘　　要：南方根结线虫Meloidogyne incognita引起的根结线虫病已经成为我国农业生产上的重要威胁,利用生物防治的方法控制根结线虫病是一种安全有效的植保措施。本研究在日光大棚探究不同剂量的生物菌肥YB-04对番茄根结线虫病的防治效果,并利用Biolog-Eco板研究YB-04对番茄根围土壤微生物群落功能的影响。结果显示,不同剂量的YB-04菌肥均能显著降低土壤中根结线虫的数量和番茄植株的根结指数,其中YB-04300 kg/hm^(2)沟施处理的线虫减退率和防治效果分别达66.0%和63.5%,且增产效果达20.2%。同时,番茄根围土壤微生物对碳源利用率增多,Shannon指数、McIntosh指数和丰富度指数显著增高,PCA分析结果显示土壤微生物群落功能与对照有明显差异。结果表明,YB-04生物菌肥既具有防病促生功能,又能改善土壤微生物群落功能,具有较大开发利用前景。The root-knot nematode Meloidogyne incognita has become a great threat to agricultural production.Biological control is a safe and effective measure.In this study,the effects of different doses of YB-04 bioorganic fertilizer against root-knot nematode were measured in a sunlight greenhouse,and the influence of YB-04 bioorganic fertilizer on the function of microbial community in tomato rhizosphere soil was studied using Biolog-Eco plates.The results showed that the number of nematode in soil and the root-knot index of tomato were significantly reduced after applying different doses of YB-04 bioorganic fertilizer.The nematode reduction rate and control efficacy of YB-04300 kg/hm^(2) applying along the rows reached 66.0%and 63.5%,respectively,with a yield increase of 20.2%.The utilization ratios of carbon sources,the Shannon-Wiener index,McIntosh index and richness index of microorganisms in the rhizosphere soil in the treatment group with YB-04300 kg/hm^(2) were significantly higher than that of the control.PCA analysis also showed that the function of soil microbial communities was significantly different from that of the control.The results indicated that YB-04 bioorganic fertilizer not only controlled root-knot nematode effectively and promoted plant growth,but also improved soil microbial community function,which have great potential for the management of root-knot nematodes.
