| Abstract: |
| A pot experiment was conducted to investigate the effects of nodule bacteria inoculation (Non-inoculation, Inoculating XC3.1, Inoculating ACCC16101) and N application levels (Non-N, 0.3 gN/kg soil) on pea and maize growth and N content in different cropping patterns (pea and maize sole, pea/maize intercropping). The results showed that inoculating selected strain XC3.1 increased effectively nodules number and weight by 79.5%～131.6% and 174.1%～205.4% respectively, and improved N nutrition status of intercropped maize and pea in two cropping patterns. The improvement of N nutrition resulting from XC3.1 was better than that from strain ACCC16101. Inoculating XC3.1 promoted pea biomass in mono- and intercropping system by 22.0%, so did intercropped maize under non N applying condition by 123.1%. More effective pea nodules were formed in intercropping system than that in mono-cropping system. Intercropped pea accumulated less dry matter than mono-cropped pea at the same N level, and the average rate of decrease was 13.7%. Inoculating XC3.1 increased significantly not only the competition of maize to pea, but also the resistance of pea to maize. |
