试验表明,人参锈腐病菌[Cylindrocarpon destructans(Zinss)Schol-ten]具有潜伏侵染的特性。在1—5年生外观无病斑的参根内,是普遍带有潜伏的锈腐病菌,参根的带菌率和潜伏侵染点值,随根龄的增长而增高。3年生人参的根系中,主根对锈腐病菌的感染率最高。春季移栽3年生参根、盆栽鹿粪和50%禾穗胺600倍侵根,均对该病菌有一定的防治效果。 Tests showed that Cylindrocarpon destructans (Zinss) Schol-ten possessed latent infection characteristics. In the 1-5 year-old appearance of disease-free ginseng roots, is generally lurking with rust bacteria, ginseng root zone infection rate and latent infection point value, with the increase of root growth. Roots of 3-year-old ginseng, the main root of the highest infection rate of rust-rot fungi. Spring three-year-old roots transplanting roots, potted deer and 50% Wo Wo Sui 600 times invaded the root canal, the bacteria have some control effect.
