文摘

Bio-fertilizer significantly decreased soil bulk density while increased soil N, P and K contents. Bio-fertilizer was superior to organic fertilizer in improving the enzyme activity and antagonistic bacteria abundance. Higher input rates of bio-fertilizer have a greater suppressive effect on Fusarium and Verticillium dahliae. SOC and available P were positively correlated with the Bacillus, Trichoderma and Pseudomonas.
