微生物菌剂对重茬地人参根腐病防治效果的研究

Study on the Control Effect of Microbial Fertilizer on Root Rot of Panax ginseng in Continuous cropping land

根腐病是重茬地人参种植中需要解决的主要问题之一.本实验采用不同微生物菌剂对重茬地人参根腐病防治效果进行研究,结果表明,不同微生物菌剂的不同施肥方法对人参根腐病病情指数、人参外观品质及耐储性存在不同程度的影响,其中施用地养力微生物菌剂(粉剂)350kg/亩和高保康3号微生物菌剂(液体)60kg/亩对重茬地人参根腐病的综合防治效果最佳,防治效果达到80%以上,鲜参的外观品质和耐储性都有明显的提高.

Root rot is one of the main problems that need to be solved in ginseng cultivation in repeated cropping fields.In this experiment,different microbial agents were used to control ginseng root rot.The results showed that different fertilization methods of different microbial agents had different effects on panax ginseng root rot disease index,appearance quality and storability.Among them,350 kg/mu of nutrient microbial agents(powder)and 60 kg/mu of Gaobaokang 3 microbial agents(liquid)had the best control effect on panax ginseng root rot disease in successive cropping fields.The control effect is over 80%.The appearance quality and storage resistance of fresh panax ginseng were obviously improved.
