摘　　要：通过对不同参场１～６ａ生参土的稀释分离情况来看，田间致病细菌Ｅｒｗｉｎｉａｃａｒｏｔｏｖｏｒａｐｖ．ｃａｒｏｔｏｖｏｒａＤｙｅ的密度为１．６７×１０￣８细菌／ｇ，Ｐｓｅｕｄｏｍｏｎａｓｃａｒｙｏｐｈｙｌｌｉ（Ｂｕｒｋｈｏｌｄｅｒ）ＳｔａｒｒＢｕｒｋｈｏｌｄｅｒ的密度为２×１０￣８细菌／ｇ，表明人事细菌性软腐病的初侵染源是土壤．从不同地区１～６ａ生１８０支健康参根厌气诱发试验结果表明，参根各部位的潜伏带菌率都在４０％以上．不同部位的潜伏带菌率存在差异，以芽孢为最高，而且真菌和细菌可以复合侵染，加速了参根腐烂的进程。Through diluting and isolating of ginseng soil from 1 to 6 years, the re-sults showed that the density of Erwinia carotovora pv. carotovora Dye was 10￣7～10￣8cfu/g,and of Pseudomonas caryophylli Burkholder was 10￣6～10￣7 cfu/g.It indicated thatthe priliminary infection and all the parts of ginseng were latently infected by bacteria,The rate of latent infection in every part of ginseng was over 40%,The rates in differ-ent parts varied,the bud was the highest.The fungi and the bacteria could be infectedcomlexly and this made the rot speed up.
