Kudzuvine root endophytic bacterium JK1801053 and application thereof

Abstract

The invention discloses a kudzuvine root endophytic bacterium JK1801053 and application thereof, and belongs to the technical field of crop biocontrol strains, the kudzuvine root endophytic bacterium JK1801053 is preserved in Guangdong Microbial Culture Collection Center on April 29, 2024, and the preservation number is GDMCC No: 64583. The bacteriostasis rate of the radix puerariae endophytic bacteria JK1801053 obtained through screening on the rice sheath blight disease can reach 80%; compared with a control group, a JK1801053 fermentation liquor treatment experiment group has the advantages that the relative growth rate of the plant height can reach 20% or above, and tillering is generated earlier. The radix puerariae endophytic bacterium JK1801053 obtained through separation and screening can promote rice growth and has an inhibiting effect on rice sheath blight disease, and the radix puerariae endophytic bacterium JK1801053 has a wide application prospect in the aspect of rice yield control.
