Primary Study on Co-inoculum of Peanut Bradyrhizobium and Molybdate and Boron

Abstract:

Aiming at molybdate and boron deficient acid purple soil from main peanut cultivated areas in Sichuan, and Mo and B requirement of peanut growth，the feasibility of Co-inoculum of peanut Bradyrhizobium and molybdate and boron was studied. The tolerance to molybdate and boron of the tested strains Spr2-9, Spr4-5 was inspected. The result indicated that the two tested strains could tolerate higher concentration of molybdate than that of boron. The compound inoculum of Bradyrhizobial strain and trace element Mo was developed. The optimum concentration of Mo was 0.4%.

Key words:Bradyrhizobium sp.(Arachis), Boron, Molybdate
