Problems solved by technology
The invention relates to a method for increasing the amount of trapping organs of arthrobotrys oligospora serving as a nematode-trapping fungus, belonging to the field of applied microbiology. The final concentration of a spore suspension of the arthrobotrys oligospora is up to 20mM through adding sodium nitrate into the spore suspension of the arthrobotrys oligospora, so that the amount of the trapping organs of the arthrobotrys oligospora is increased, and the nematode killing capacity of the trapping organs of the arthrobotrys oligospora is improved. The method has the beneficial effects that a great number of trapping organs are generated by the arthrobotrys oligospora after NaNO3 is added in the spore suspension of the arthrobotrys oligospora, so that the nematode killing capacity is remarkably improved, and the death rate of nematodes is up to 85.88% when the nematodes are added for 12 hours; and when the nematodes are added for 24 hours, the amount of the trapping organs generated on a flat plate on which sodium nitrate is added is more than six times as much as the amount of the trapping organs generated on a flat plate on which no sodium nitrate is added, and the death rate of the nematodes is up to 99.80%.
